7200RPM HDD slower than 5400RPM

I just bought a 13" Macbook Pro and I simply took my old HDD from my white macbook and put it in the new MBP and booted. Everything has been working fine except I've noticed its a little slow. I'm not sure if there is something or anything I can do aside from reloading the OS. Here are the xbench results. The 7200RPM should be faster but it definitely is not both in real world experience and according to this bench. My guess is it has something to do with the move from one macbook to another without reloading OSX.

Thanks for any help!

If you cloned like that and got all of your hardware working you're pretty lucky I would say. To give you an example - take an install drive from say my old Macbook (2007 Whitebook) and pop it into my MBP with the dual graphics cards... It boots, it works.....But can I switch graphics cards? No chance.
It's stuff like that that's your issue here.
Until you have a known good install it's impossible to fault find such things like as being asked. In my opinion anyways. If you have weird stuff going on that you can't bottom often it's a case of making sure stuff is right. Dropping one drive from one platform into another is not one of those right things.
In defence of all things Apple though - just try that on a Windows laptop and see how far it gets you

MBP 15" 2.4GHz - 5400rpm vs 7200rpm HDD?

I intend to buy a 2.4GHz 15" 4GB RAM MBP. I am in a fix right now about going for which of the two HDDs 5400rpm vs 7200rpm (both of 200GB). The MBP with the default configuration(ie with 5400rpm) is for only 1699$ due to some stock clearance offer at my educational store. But, if I go for the 7200rpm the machine will cost me $1799+98, implying more $200. I intend to buy the extra 2GB RAM separately. Is it really worth it spending more 200$ on the 7200rpm HDD in my machine? I am a performance freak, and being a computer graduate student end up spending most of the time on my machine. Anyone who has used both the machines, please let me know if there is any noteworthy difference? I do understand that the decision is my personal one; but, please throw some insight and help me in making a decision quickly.

I bought a 7200rpm 100GB drive with my mbp. About a week ago I upgraded to a 7200rpm 320GB drive because I needed the space. If you, like me, are a performance freak, go with the 7200. I did and never regretted it. In fact i dealt with the space issue by buying a 500GB and a 1TB external (FW800). Because the new current MBPs use a 3.0gbps SATA interface, getting the 5400rpm might give you a bottle neck.
this is what i have now:
http://www.seagate.com/www/en-us/products/laptops/momentus/momentus_7200.3/
original was the momentus 7200.1
If you compare the 5400.5 and the 7200.3 you'll see that there is a 20MB/s difference is sustained transfer rates. Considering the 300MB/s transfer rate of the 3.0 SATA interface, you will notice a difference. SATA likes 10k rpm plus, 5400 just doesn't cut it anymore. If you don't care about voiding the warranty, go to newegg and get the 7200.3 320GB. I got mine for about $175ish OEM (can't remember). Then turn your old one into an external.
Oh, and this thread is off limits for bickering about the differences between mebibytes, megabytes, and megabits.

MBP slower than ever...

I just upgraded to Snow Leopard, then swapped a 250gb 7200rpm hard drive for a 500gb 5400rpm hard drive. Now my computer is slower than ever. It still works, but at a much slower pace. Often the screen will freeze for up to 10 seconds before becoming operable again. This happens when doing the simplest of tasks. I am only running about 5 programs at a time anyways. This never happened on the old system. And I don't think its a matter of the slower hard drive. I was running an old MB with a smaller HD, same RPM, same RAM, and there was no problem. What gives? What should I do?

OK. Let's proceed on the premise it's not the drive. Although, I swapped an 80GB 5400 drive on an iMac G4 for a 160 GB@7200 and noticed quite a difference.
How did you install, clean install with Migration Assistant, clone, Time Machine?
There are some simple troubleshooting steps you can take.
Create a new User go to System Preferences >> Accounts >> "+" (make it an admin acct) and test your apps in this new account, if they are faster the problem is isolated to your User and not systemwide.
If the issue is limited to your user account try starting up Safe Mode (It will take more time to startup in Safe Mode because it runs a directory check.)
If your apps functions faster that way, go to System Preferences >> Accounts >> Login Items, and remove them. Boot normally and test. If not go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving ~(yourHome)/Library/Fonts to your desktop and restarting. Also, delete Users/yourname/Library/Caches. (on the first launch after this some apps will be slow until cache catches up.)
Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
If the issue is systemwide then, you may be able to repair this with the The 10.6.2 Combo Update This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.
Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.

Macbook pro 2012 is slower than macbook air 2012

I have found that my macbook pro 2012 13" (non retina) is slower than macbook air 13" my co-workers own. all macbooks have same softwares and versions.
Macbook pro has better processor but Macbook Air is faster. I guess it is because of Hard drive in pro vs SSD in Air. so my questions are:
Does anyone have a same exprience?
and if I change my HDD to SSD can i beat macbook pro in speed?
waiting for your quick answers because I am feeling bad these days.
Thanks in advance

Take a look at my one and only user tip - Upgrading Your MacBook Pro with a Solid State Drive.

New hard drive slower than old one

Hello, my Seagate 120GB 5400rpm drive crashed 6 weeks ago and I made use of the warranty to get a replacement (refurbished) drive. I think this drive is no good because I have noticed a marked decrease in performance:
-Upon coming back from sleep mode the screen turns on but it pinwheels for several seconds, showing the time it was when I put it to sleep.
-My battery also lasts considerably less now. The battery is about a year old and had been lasting me up to two hours. It now doesn't last much more than one.
-I also tried to rip a dvd today and had to stop because it was going 5x slower than it had even on this drive when I first got it.
Is there anything else that could be causing me this decreased performance besides a subpar drive?
I have been in touch with Seagate again this weekend and they suggested I send it in for another replacement, which is fine, but is there a way I can copy all of this drive onto my replacement when it gets here? Or should I need to start fresh and reinstall everything on the new one?
Thanks.

You might want to check that you have selected a startup disk as "Macintosh HD" so the OS x knows where to boot from. If there is no selection under startup items in System Preferences then boot up is delayed by a few seconds as OS X would look for a functional startup disk.
Check and see if this works for you in bringing down boot times.

New Mac Mini slower than my 4 years old iMac

My Intel iMac (20" display) four years old is out of order (I think the Power Supply was gone), and I bought the new entry level Mac Mini.
When I started using it I noticed that it's much slower in several tasks than my old iMac (when restarting, when opening applications, when working with an app with another appl in the background, etc. etc.). I was concerned about this, but then I asked some friends that have Mac minis and they said that it's normal.
Why? Why a computer with a new i5 Intel processor can be slower than a four years old iMac Core 2 Duo? Is it because of the slow drive (5200 rpm)? Or what is the explanation? If this is normal for the mini, I'll try to fix my old iMac as soon as possible.

Don't downgrade to Lion. For what it's worth, my experience with Lion and Mountain Lion has been almost the exact opposite than what CaptH reported: I find ML to be much faster and more reliable, both on my late-2012 Mini and my mid-2007 iMac.
Your perceived speed issues are almost certainly a result of the slower-spinning hard drive in the Mini as Shootist007 pointed out earlier. Go ahead and disable Spotlight if you want to, but once the indexing is complete (which can take a few hours – or even a few days if you have a lot of data) it shouldn't be a problem unless you are continually connecting different large external drives.
Get the latest Combo Updater and install that. If you have some minor OS issue, that should solve it. Do a normal Software Update / check the Mac App Store for updates after you install the Combo Updater. Get it here:
http://support.apple.com/kb/DL1640
If you continue to be bugged by the slower speed, see if your local Apple Store will allow you to exchange it and a little extra money for an equivalent model with a Fusion Drive. Or go to Other World Computing and purchase their kit to add a second drive, and use it to add an SSD in the second drive bay:
http://eshop.macsales.com/item/OWC/DIYIMM11D2/
http://eshop.macsales.com/search/OWC.INSTANT.481.2
Also, RAM is super-duper-uber-cheap right now. If your Mini has only the stock 4gb of RAM, you might be pleasantly surprised by the improved performance by doubling that. I have 16gb in my Mini, it cost me well less than a hundred bucks, and it makes everything better including graphics performance. But if you don't do something to work around that slow 5400rpm hard drive, it will always be the bottleneck in your system.

7200RPM HDD in 15" MBP (Merom)?

I'm not realy sure if this is the right place for this, but really none of the catagories fit what I'm asking. Basically, I wanted to know if anyone has found a way to get a 7200RPM HDD installed in the Merom-based MBP lately? I know technically, if I wanted it that badly, I could do it myself. But, honestly, I'm a lot more comfortable working on desktops (AMD desktops, at that) than I am mobiles, and I'd rather not have to worry about it. I see the option is available for the 17" - curious if, despite it not being on the site, someone had any advice or input on my chances of getting one put in from the factory? I'm REALLY tempted to get one, but this is kind of a buy-or-don't-buy point for me.
Thanks in advance!

If you're worried about it, do not do the install. Despite how difficult/easy it may be for some, if you all ready think it might be a problem don't risk destroying your new $3,000 machine.
There had to be a reason they did not put the 7200 drive in the 15" and since we know heat is a problem it is reasonable to assume they ran tests with the 15" and determined the heat was just too bad (as many current 15" owners have said themselves). I would just get the 15" with the 5400 drive if I were you.

Preview takes forever to open, much slower than on my old MacBook. It has been like this since I bought the computer last January. Why is Lion so much slower?

Preview takes forever to open, much slower than on my old MacBook running Snow Leopard. It has been like this since I bought the computer last January. Any ideas?

Take it to an Apple Store for testing. If you don't get immediate satisfaction, exchange it for another one, which you can do at no cost, no questions asked, within 14 days of delivery.

Why is Thunderbolt so much slower than USB3?

I'm considering two different drives for Time Machine purposes. Both are LaCie. Either of these:
- Two Porsche 9233 drives, 4 TB each
OR
- A 2Big Thunderbolt drive, 8 TB, which I would configure as RAID 1 (a mirrored 4 TB volume)
My question is this: I've viewed both of these product pages via the Apple Store, and I noticed that LaCie's information for the Thunderbolt drive makes it a lot slower than the USB drives. Meaning: They say that the 2Big Thunderbolt drive maxes out at like 427 MB/s, whereas the Porsche USB drives max out at 5 GB/s. Why is this? Isn't Thunderbolt supposed to be a lot faster than USB (any iteration)?

Not an easy question, short of a whole lot more detail on the construction of those two devices.   You're likely going to need to look at the details of the drives and probably at some actual data.   You're really looking for some real benchmark data that you can compare, in other words.    Particularly which (likely Seagate) drives are used in those (IIRC, Seagate bought LaCie a while back), and what the specs are.
The hard disk drives themselves are a central factor, where the drive transfer rate is a key metric for big transfers (and that can be based on drive RPM as much as anything, faster drives can stream more data, but they tend to need more power and run hotter), and access (seek) time for lots of smaller transfers (faster seeks mean faster access, so good for lots of small files scattered around). Finding the details of the drives can be interesting, though. I've seen lots of cheaper disks that spin very slowly, which means that they can have nice-looking transfer times out of any cache, but then... you... wait... for... the... disk... to... spin.
The device bus interfaces can also vary (wildly) in quality.   I've seen some decent ones, and I've seen some USB adapters that were absolute garbage.   Some devices have decent quantities of cache, too. Others have dinky caches, and end up doing synchronous transfers to hard disks, and that's glacial compared with memory speeds.
One of your example configurations also features RAID 1 mirroring, which means that each write is hitting both disks.   The writes have to pass through a controller that can do RAID 0 mirroring, and that can write the I/O requests to both drives, and that can read the data back from (if it's clever) whichever of the two drives is best positioned in related to the sectors you're after.   If it's dumb, it won't account for the head positions and drive rotation and sector target.   Hopefully the controller is smart enough to correctly deal with a disk failure; I've met a few RAID controllers that weren't as effective when disks had failed and the array was running in a degrated mode. In short, RAID 1 mirroring is a reliability-targeted configuration and not a performance configuration. It'll be slower. Lose a disk in RAID 1 mirroring, and you have a second disk with a second copy.    If the controller works right.
If you want I/O performance without reliability, then configure for RAID 0 striping.   With that configuration, you're reading data from both disks. But lose a disk in a RAID 0 striping configuration and you're dealing with data recovery, at best. If the failure is catastrophic, you've lost half your data.
But nobody's going to make this choice for you, and I'd be skeptical of any specs outside of actual benchmarks, and preferably benchmarks approximating your use. Reliability is another factor, and that's largely down to reputation in the market; how well the vendor supports the devices, should something go wrong. One of the few ways to sort-of compare that beyond the reviews is the relative length of the warranty, and what the warranty covers; vendors generally try to design and build their devices to last at least the length of the warranty.
Yeah. Lots of factors to consider. No good answers, either. Given it's a backup disk, I'd personally tend to favor eliability and warranty and less about brute speed.
Full disclosure: no experience with either of these two devices. I am working with Promise Pegasus Thunderbolt disk arrays configured RAID 6 on various Mac Mini configurations, and those support four parallel HD DTV video streams with no effort. The Pegasus boxes are plenty fast. They're also much more expensive than what you're looking at.

URLClassLoader slower than system loader

I'm subclassing URLClassLoader to load jar files on the local file system. I noticed that URLClassLoader loads about 30% slower than placing the jar files on the system class path. In my app, class loading performance in very important -even though it is just a one time hit.
I suspect the URLClassLoader (which I believe is implemented mostly in Java on Sun's VM) is not leveraging the many performance optimziations that the system loader enjoys (which is probably implemented in native code).
I also experience the same performance issue if I try to do jar loading myself using Java ZipFile i/o.
Comments?

well there is quite more overhead involved - loading from classpath of course is the most optimized one.

I used to be on a voyager 220v router but started having connection problems. After speaking to customer support, and after they ran some tests on the line/router, they told me that the fault was with the 220v and as it was obsolete, i would need to change to a HH3.
After receiving the HH3, im now finding that the d/l speed for webpages is slower than it was on dial-up. Ive tried running speedtester but it fails to complete and just gives an error that it cant be completed at this time and to try later. After reading another thread on this issue, i went and found the settings from the hub itself, these are posted below:-

is their anything amongst the above which explains why its running so slowly?

Bah, this is a PITA.
Got up around 7am and the HH3 was displaying connection time of 10 hours, great, lets leave it for 24 and see what happens. Tried browsing and pages were incredibly slow to load, thats when they did actually load. I said stuff it and took the dog for a walk and left everything as is. Got back and checked again at 9.15 to find a connection time of 14 mins, so obvioulsy something has reset itself.
Tried speedtester and quite simply, the page would not load in order for me to test it.
Tried clean line check, sounds perfect, no noise whatsoever on it.
Tried connecting to the test socket and now get the following results:-

I have my Mac Book Pro with the OS Yesomite since a month and I am feeling that my mac is getting slower than before a month. I want to install OS Lion on my mac. I think i have a DVD of OS Lion which comes when i bougnt Mac laptop in 2011.

I have my Mac Book Pro with the OS Yesomite since a month and I am feeling that my mac is getting slower than before a month. I want to install OS Lion on my mac. I think i have a DVD of OS Lion which comes when i bougnt Mac laptop in 2011. Should i install OS Lion? What wil happen if i install OS Lion, do i lost my Applications or ...????

Hi, the last install dvd that came out for mac's was Snow Leopard,10.6.3. Lion is a download from apple. You cannot just install it over Yosemite. You would have to backup your drive to save files you want and do a clean install. You might want to look into getting more memory. You can run 8 Gig"s of memory on your Macbook Pro.If your Macbook Pro is getting really slow you might want to download EtreCheck and then post the results here.http://www.etresoft.com/etrecheck Check out this article. http://support.apple.com/kb/PH19031

Mac OS internet 5x slower than Windows 7 on BootCamp

Alright, here is my problem...
My one and only computer is a mid 2010 iMac... I recently moved to a new place. Prior to me moving I was stuck with an awful 3Mbps download speed. (You can tell how much I hated it by looking at my username) Now that I moved, I am able to get much faster internet. So, I got a plan that offers up to 50Mbps download speeds (Xfinity Blast cable internet). I didn't want to rent my ISP's modem/router, so I purchased my own. I got a Motorola sbg6580. As soon as I got everything hooked up, it seemed perfect. I used speedtest.net to see what I was getting. I first tested on Windows 7. To my surprise, I was getting around 70Mbps. I then restarted my iMac into the Mac OS to do some speed tests. On the Mac OS, I was getting around 50-60Mbps. A bit slower than Windows 7, but still very good. The next day I decided to do a "real world" test. I downloaded a 1 Gigabyte file just to see how fast it was. Now, if I was getting 50Mbps the file should have taken just under 3 minutes to download. Instead, it took around 7 minutes. I figured it was maybe just the website I was downloading from. (the file I was downloading was the Cry Enginge SDK - http://www.crydev.net/ ) I did some research and discovered the website testmy.net - I am not sure if this is completely reliable or not, but every test I do on testmy.net I get around 10Mbps. At first I thought it was my ISP ripping me off, then I decided to do a testmy.net test on Windows 7 via BootCamp. (please note that on both Mac OSX and Windows 7 I did multiple tests over the coarse of multiple days) On Windows, I could instantly tell that the test was going much faster. The results for testmy.net on Windows 7 were 50-60Mbps. I did not completely trust the website, so I downloaded the same Cryengine SDK on Windows. It took around 3 minutes, just as it should have. I researched a bunch online trying to find info on this problem. I tried many "solutions" but none of them changed anything. (these include but are not limited to: Tried different DNS servers, Disabled ipv6, disabled sbg6580 firewall, disabled mac osx firewall, tried changing the wireless channel, and reset sbg6580. I came to the conclusion that it was the sbg6580. I thought that maybe an airport express would give me better results. So, today I bought an Airport express. With the sbg6580, I was able to disable the router features so it was just a modem. I was then able to set up the Airport express as my router. It fixed nothing. I am still getting the same results, Windows is still getting anywhere from 50-60Mbps while Mac OSX is getting around 10Mbps. I am out of ideas, if anyone could please help me that would be great. Also, if you need to know anything else please let me know. I may have missed something...
A quick note:
At my old house I had my iMac hooked up to a surge protector. For maximum internet performance, my iMac was connected to my router with an ethernet cable. During a bad storm one day, a lightning bolt either hit my house or very close to it. Ever since, my ethernet port has not worked. I have tried multiple eithernet cables as well as multiple routers and networks. I do not have the money for apple to completely replace my logic board. - So anyway, I am unable to test the performace with an eithernet cable.
Extra information:
My sbg6580 as well as my Airport extreme are both sitting on the same desk as my iMac, so it is obviously not a signal problem.
I also own both a iPod touch 5th gen and a iPad 2nd gen. I am getting around 20-30Mbps on both of them. I am not sure what would be a "good speed" on either of these, but I figured that was pretty good for a tablet and ipod.
The upload speeds on both windows 7 and Mac OSX are around the same 5-10Mbps.
I am using Google Chrome on both Windows 7 and Mac OSX but, I have also tried Firefox and Safari.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Flash player 10.1 slower than 10

At least, that's how it is on my secondary computers. On my Dell Inspiron B120, flash 10.1 latest is like a train wreck when it comes to playing Youtube videos in full screen. Disabling hardware acceleration helped a little, but this shouldn't be happening as I uninstalled 10.1 and installed an archived version of Flash 10 with much better playback AND with h/w acceleration enabled. The laptop uses XP SP3 and Firefox.
Simply put, Flash 10.1 feels a lot slower than 10 on my Dell laptop (1.4 GHz celeron-M, intel 915g video, 512 mb ram)
And there's another odd but minor problem I seem to be having with is flash animations on my main computer and any other computer/laptop I have using Flash 10.1. I get this alternating 'lag' every few seconds; it's like the computer is dropping frames because the CPU can't keep up. I could completely understand this, but this is happening on practically any flash animation I throw at the computer. I just tested a flash movie (SWF format) on my main computer (2.8 GHz AMD Athlon x2 240; 2 gb ram, Windows 7 x64, Firefox) and I get this irritating choppy lag here and there. Again, with the previous Flash version 10, I did NOT have this problem AT ALL. Everything was silky smooth; the only benefit I'm getting from Flash 10.1 is x264 hardware acceleration for my ATI Radeon 4200 HD. Before anyone asks, all of my computers were using the latest flash version AND video drivers prior to these tests.
I am VERY frustrated with these problems as I've posted a similar thread twice now in the past. No one seems to be answering or helping me with this; Those that do reply simply claim that they're having the same problem.
Adobe, please look into this problem. Eventually Youtube and several other sites will force me to upgrade my laptop to Flash 10.1.

Has Adobe fixed the problems with version 10,1,82,76 of flash player ?
I compared it and found nothing but problems.
I then uninstalled 10,1,82,76 and rolled back to 10,0,12,36 which works fine on Firefox and Opera but I can't install 10,0,12,36 on Exploer or Chrome
it keeps telling me there is a new version even when I try to install it from local drive with a archived version.
With all the complaints about 10,1,82,76 and the lack of response from Adobe on any fixes I will not be using Adobe auto updates until I let some
other poor guinea pigs suffer all the bugs and problems first.
You would expect a large company to have better development and testing before imposing buggy upgardes on us.
