Noticeable speed difference between 5400 and 7200?

My Mac dealer suggests two HD upgrades for the new Mini:
Either the 5400 rpm WD5000BEVT
or
HD intern Momentus 320 GB Sata 2.5" 7200 RPM 16MB
Anybody knows if the WD5000BEVT offers any speed speed advantages worth mentioning over the standard Mini disks?
With the HD intern Momentus 320 GB Sata 2.5" 7200 RPM 16MB, I'm not sure about the extra heat and consequent fan noise.
I do use FCP 6, but no other Studio applications.
Thanks,

The greater density of the platters on the 500GB drive will make it faster than a 320GB 5400rpm drive compared to a 320GB 7200rpm drive, though the latter will still be faster. I'd go with the 500GB drive (which I did end up doing with my MBP) due to greater capacity, lower noise, and it's still fast.

Speed difference between 5400 and 7200

I just wanted to share that I replaced my Seagate 5400 640GB with a Seagate 7200 750GB today, and noticed a substantial speed increase. I mention this because I've seen a lot of questions it. Thanks. Normal programming will now resume.

Difference between 5400 and 7200 hard drive

Looking at buying a new MBP - can't decide on the 750 G 5400 HD or the 500G 7200 HD. I like the extra space for photos on the 5400 HD but will the 7200 be a snapper unit ? I can always use an extra drive for storage - but is the speed benefit noticeable ? I can't seem to find any recent reviews. They all seem a few years old. Plus - not sure whether the bigger drive will be just as snappy (more space) as the faster drive (possibly fulling up).
Advice anyone ?

And probably to your surprise, they still spin at the same speeds. 5400rpm & 7200rpm.

Is there a big difference between 5400 and 7200 hard drives?

I dont know which one to get. Should i upgrade to the 7200. Right now i have a 7200 hard drive in my powermac g5 and its great so would it be alot slower with a 5400 hard drive. Also to upgrade the drive do i have to order it online or can they upgrade it in the apple store?

Barefeats did some tests, and they conclude the Momentus 7200 is worth the upgrade. Also note this drive is slower than some other newer drives, so you could even get a greater advantage from other models. I've bolded pertinent information. Please note most performance increases are not seen in everyday emailing, web surfing, etc.
http://www.barefeats.com/hard56.html
Their Conclusion:
ANALYSIS
The Seagate Momentus 7200.1 takes notebook drive speed to a whole new level. It's not as fast as the fastest 2.5" (ed) 7200rpm drives but it's impressive nevertheless. And its quiet. It's a no brainer for a PowerBook internal drive replacement or as an external drive in a FireWire 800 enclosure.
WILL A 7200RPM NOTEBOOK DRIVE DRAIN MY BATTERY FASTER?
The short answer is, "Probably not." You see, the 7200rpm drives are as much as 28% faster doing random reads and writes compared to the 5400rpm drives. They are as much as 80% faster than 4200rpm drives. Yet the Hitachi Travelstar 7K100 uses the same amount of power as the Travelstar 5K100. The Seagate Momentus 7200.1 uses only 10% more power than the Momentus 4200.2. The Momentus 5400.3 uses less power than the Momentus 4200.2. My theory is that the "speed to power" ratio is so good with the 7200rpm drives that the net effect on the battery is negligible.

Real world performance/speed difference between 3ghz and 3.2

Hello,
I have a 2008, (not clovertown) Harpertown 3.0ghz Mac Pro. I wanted to know if its feasible to upgrade the cpus to the 3.2 ones? Also, what is the REAL WORLD speed/performance difference between the 3.0 and 3.2? I am so stressed out over this that I really need to have an answer to this.
Not that I am going to buy the 3.2 processors, just wanting to see what I am missing here in terms of percentage overall between my mac pro and a 3.2ghz mac pro from 2008.
Thank you,

You realize that by now you can probably guess what some of our answers might be?
Real world... well, in the real world you drive to work stuck in traffic most of the time, too.
Spend your money on a couple new solid state drives.
You want this for intellectual curiosity, so look at your Geekbench versus others.

Speed difference between hotspot and cellular

INternet speed difference between iMac and MBP

I have an imac 27" that is barely one year old and a three year old MBP. Today, I signed up for faster Fios internet service which is supposed to be a maximum of 25 Mbs both up and down. I then checked the speed on my iMac and see I am averaging about 10 Mbs down and about 8 Mbs up. I am not that concerned that I am not getting the theoretical maximum performance. For one thing I am not hardwired to my router but am using wireless g. I also ran the Mac internet tuner that seemed to actually increase the speed somewhat.
I then checked my MBP that is sitting right next to my iMac. I am getting around 15 Mbps down and about 17 Mbps up. I repeated this several times as I did for the iMac. I am surprised at the iMac being so much slower (about 33% slower). I can only assume the hardware in the MBP is better for wireless communication than in the iMac. Can someone explain why this is so?
thanks,
Shannon

Speed Difference between SQR and PL/SQL

Hi
I have converted a whole SQR report code into PL/SQL. The code includes extracting data from tables and then writing them to the extract files. What we've done is we've put the entire logic into PL/SQL within stored procedures and only write to the extract files within the SQR by calling the procedures through SQR. Now the problem we are facing is the timing issue whereas the whole idea was to increase the perfomance.
What takes maybe3 hours to finsh the job in SQR is taking the double time in PL/SQL. I just have a question that before i insert into my rpt tables from where i extract data in the SQR to be written to the extract file, i am doing a lot of manipulation on the variables. Like i have about 10-12 NVLs, RPADs, TRIMS going on just before inserting those variables in the table . I just want to find out is that what is taking so long. We've checked the indexes, used the Hints, the speed is still the same.
Any help right now will be greatly appreciated.
Thanks to all.

WRT54G2 v1 - Substantial Speed Difference Between Wired and Wireless Connection

Hi everyone,
I have a WRT54G2 v.1 router connected to an RCN Cable Modem. My download transfer rate direct from the cable modem is 18 Mbps. Thankfully, I can get the same download rate when I plug my laptop into a wired ethernet connection from the router. However, the wireless connection only gets a download rate of 0.8Mbps. Also, my wireless card is pretty new (Intel 4965AGN) and has the latest driver (I can get far higher download rates at mobile hotspots, for instance). Here is what I've tried with the router:
- I've upgraded the router firmware to the latest build (Version 1.0.04, 07/08/2009).
- I've tried multiple channels on the network (1, 6, 11).
- I use WPA Security.
- Upon advice from the Linksys live chat support, I've changed the MTU settings to manual and set them to 1300.
- They also recommended that I change the following settings: “RTS Threshold” – 2304 “Fragmentation Threshold” – 2304 “Beacon Interval” – 50
- And of course: I've got my own SSID. The router is 5 feet off the ground. There are no other wireless devices that would cause interference. The router is not near large metal objects, fish tanks, or any other physical obstruction.
Is there anything else I can do? Thank you so much in advance for reading. I really appreciate it.

Also, is there anything to the fact that only the download rate seems to change?

Any speed difference between Apple Wifi Router(air express) and Tp link(or others) wifi router)

Any speed difference between Apple Wifi Router(air express) and Tp link(or others) wifi router?
I'm using a tp link router and sometimes it takes a long time delay for my 2 mac computers to connect each other. I don't know this is because of the router compability or the computers.

Anyone knows?

Question about the difference between HDDs and SSDs

Hi. I currently have a MacBook (Black one) that's overheating a lot for the past few months. I'm thinking about purchasing a MacBook Pro for school because it seems to be more stable. I have a question though. What is the difference between HDDs and SSDs? Which one is better? All I know is that with my MacBook and my iBook is that I had hard drive failures (iBook hard drive clicking, MacBook hard drive sounding loud and making my computer overheat). Are hard drive failures normal with Macs?
Thank you

Depends what you mean by "better." Faster? Yes. The 500 has 3x more storage capacity.

Is there much speed difference between the iMacs?

Just wondering, if there is any noticeable performance difference between the 1.83 - the 2.0 and the 2.16?
I'd be surprised to learn that there was (and also, keenly interested to learn).
My experience is that a dual processor is noticeably more capable than a single processor (regardless of minor increments at the end of the processor number).
Anyone?

You are right that it is more about futher differentiating the models than anything else. The speed difference is negligible, but a nice plus is you choose a larger display. Typically you also get a larger standard HD and maybe a better video card and if you add all those things up, the price difference is worth it.

What is the difference between SWF and F4V in the context of Streaming or progressive Download?

Hello everybody,
I am absolutely a beginner in working with Captivate and furthermore my technological know how is not that good.
So, I have problems to understand if the export formats SWF and F4V are both capable to be published in the Internet as streaming video and as progressive Download? Well so, I do not really understand the difference between streaming and progessive download either?
Furthermore I was asking myself if this issue depends on how I imported flash videos (there are these two options) in my Captivate project during the production phase?
I would be very thankful for some helping information!
Greetings,
Mareike the beginner

Welcome to our community
I'm not certain I fully understand the differences myself, but will toss out what I believe to be true about the formats. Hopefully, if I'm incorrect in my bellief, someone with more definitive knowledge will chime in.
It was explained to me a couple of years back and is my understanding that "streaming" only applies to a video based format such as F4V, FLV and it doesn't apply to SWF. With SWF, you may specify a preload value. So when the SWF transmits from the web server to the PC, a certain percentage has to be received before play begins. But that's not streaming. It's preloading.
For streaming to occur, the web server establishes a communication channel between the server and the destination PC. This channel is monitored to see what speed is in use. Only enough information is then transmitted to be comfortable at that speed. If the speed improves during the connection, the server serves data at a faster rate. If the connection degrades, the information transmitted is also scaled back so as to accommodate the lower speed.
With SWF, after it has all been downloaded, a savvy user is able to poke around in their temporary internet files and save the SWF for play later. With streaming, this isn't possible because as the stream is viewed, it evaporates from memory.
Seriously hoping others will chime in here to confirm or deny this.
Cheers... Rick

AppleScript speed difference between 10.4 & 10.5

This post is related to a question I posed in March 2009 (https://discussions.apple.com/message/9226100) regarding the speed difference between AppleScript text handling in OS X 10.5 compared with 10.4.11.
I have recently written a script to search through a text file which is an xml file exported from WorkGroup Manager. The file, which is approximately 1.8 MB, contains all the user names on the school server (just over 1720 of them), their settings and any other information we have added. After adapting some script ideas (using text delimiters and offsets) which I found on the internet to assist with counting the number of users and searching through the information of each one, one at a time, I have a script which works far in excess of my expectations in terms of speed when run under OS X 10.4, but runs slower than molasses in winter under 10.5.
The script counts the number of accounts, extracts each user's log-in name and also their actual name (which we have entered under a 'general info' or 'comments' field - I can't remember exactly where, but it is stored in the file), makes up a complete list of all account names (with the actual name, if present) and also makes up a subset of this information into a separate list which contains only the log-in names of those whose actual name has not yet been recorded on the server, then saves both lists to separate text files.
My original attempts, using some rather clumsy text searching and comparison techniques, took about 1-2 minutes to go through the whole procedure. After some internet searching, head-scratching and a bit more more work, the finished script, when run on my G5 under OS X 10.4.11, takes less than 3 seconds to do all I have described above, including the writing to text files. To say I was pleased would be an understatement!
Because the school/work environment, where the script would be run, is all OS X 10.5 or higher, I thought I should test it out under at least OS X 10.5. The script was developed on my DP 2.5GHz G5 with 8GB RAM running OS X 10.4.11. Using a fresh, clean installation of 10.5 I ran the script and was extremely disappointed. After letting it run for more than 20 minutes and still not finishing, I force quit AppleScript and reduced the number of accounts in the file. 40 accounts took 3 seconds, 60 accounts took 6 seconds, 80 took 11 seconds, 100 took 19 seconds and 120 took 27 seconds. I eventually let the script run right through - total time taken to process 1720 users was 65 minutes, compared to 3 seconds under 10.4.11!
Given that it was tested on the same Mac, with the same amount of RAM, using the same script and the same original text file, the only variable left (that I can think of) is the change of OS version - 10.4.11 vs 10.5.
As was pointed out to me in my previous post, AppleScript in OS X 10.5 handles all text as Unicode and has a greater overhead in processing time as a result. I have implemented the various bits of advice offered by respondents to my original post and changed the way I handled lists, etc. Obviously, if the script works so speedily under 10.4.11, I must have done something right in terms of code optimization/efficiency. It's when that exact same script is run under OS X 10.5 that it slows down incredibly. I even tried it on a 2.66GHz Intel Core 2 Duo iMac running 10.5.8 - it still took 40 minutes and Activity Monitor showed CPU usage by Script Editor constantly above 80% (often well above 90%). Saving the script as an application made no difference in the time taken.
Does anybody have any knowledge about what makes AppleScript Unicode-only text handling so slow? In this case, it is 1300 times slower! Is there any way of coercing/restricting the text handling/parsing to ASCII? If I really have to, I will set up a humble eMac at school with 10.4 on it just to handle large text files quickly with AppleScript, but I would prefer to be able to do it on the normal work Macs which have 10.5 or later on them. As mentioned, under 10.4.11 the script processes the 1.8MB text file with 1720 users and writes results to two files - all within 3 seconds, so I'm not really looking for coding suggestions unless they are directly related to what has changed in AppleScript under OS X 10.5. Without sounding too smug, the script works properly and speedily (at least in 10.4). I really would like to learn about the changes in AppleScript in OS X 10.5 and how to cope with or work around those changes.

Hi,
text 3 thru 14 in largeText

These lines will be slow on Leopard
Getting some text in a variable that contains more than 60000 characters will be slower on Leopard,
but I don't know why it's slower
Here a test script.
script o

end script
set a to "abcdefghij"
set tResult to ""
repeat with i from 1 to 3
    set o's t_text to a
    repeat (item i of {17, 15, 14}) times
        set o's t_text to o's t_text & o's t_text -- add characters in the variable

tResult
Here the result on my old G5, 2 x 1.8 GHZ
Getting text in the variable which contains 1310720 characters, (20 times) = 50 seconds.
Getting text in the variable which contains   327680 characters, (20 times) = 12 seconds.
Getting text in the variable which contains   163840 characters, (20 times) =   6 seconds.
The result on the same machine on Tiger is always less of one second.
Also, I try with 20 millions characters on Tiger, the result : getting text in the variable which contains 20971520 characters, (20 times) = 0 seconds.

Brightness differences between Menus and Video Tracks

I am trying to learn DVD Studio Pro 3.
My project has a "roster" menu that leads to several submenus. I want an animated transition from the "roster" menu, to each of the submenus.
I built each of the animations in After Effects. They all start with the same first frame -- the "roster" menu. Each animation has a different ending frame -- one of the submenus. I rendered the animations as QuickTime movies in After Effects.
Also in After Effects, I used the "Save frame as" menu to make a flat .PSD file of the first frame (for the "roster" menu,) and each end frame (for the submenus.)
I imported all the files into DVD Studio Pro. I laid out the menu structure, drew buttons, and connected them all the way I wanted. Each button on the "roster" menu points to the start of a track, and the End Jump of that track points to a submenu.
The logic of all this works the way I expect, both in DVD Studio Pro's simulator, and on a burnt DVD. However, there is a noticeable brightness difference between the video tracks and the menus.
How can this be, if they are derived from the same graphic source?
Mac OS X (10.3.9)

There could be a ColorSync issue with the PSD. Either take it into Photoshop and try no ColorSync (or a different setting), or take a single frame of the video and make it last a while, and use that as a motion menu.
I have cured these differences both by changing the ColorSync settings of the PSD, and also by setting the monitor to generic RGB. That was enough to make DVD SP ignore the ColorSync settings in the PSD I was using.

Noticeable speed difference between 5400 and 7200?
