LR3 choice - 5400rpm to 7200rpm or 4GB to 8GB

What will LR3 like more... faster HD or more memory?
Macbook Pro 2.4 i5

First of all, let me clarify, Haven't a clue about much of this stuff and certainly not on par with your experience, But, funny, just read an article in PC World that defragging the newer bigger drives was a Waste of time?
What are us Know Nothings to do?:) I deleted Defragger right after I read the article, should I re-install?

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.

Noticeable difference between 5400RPM and 7200RPM?

I am just wondering if anyone notices a large difference in loading times, games, etc. between the 5400RPM and 7200RPM hard drives? I am a bit worried with movie editing and music, gaming, etc. Thanks.

Yes, well sort of. I upgraded my 5400 RPM drive to a 7200 RPM drive and the difference is very noticeable. Some 5400 RPM drives are slower than others some are faster..same for 7200 RPM drives. So if you go from a slow 5400 RPM drive to a fast 7200 RPM drive the difference is very noticeable.

5400rpm or 7200rpm? - MBP 2011 17''

Hi people!
I will buy an MBP 17'' but...
I don't know if I should choose 5400rpm or 7200rpm hard-drive.
I am developer and I want good mobility...good battery autonomy.
With 5400rpm, mac have 7 hours browsing... but with 7200rpm drive, how much i will have? 6,5 hours?
7200rpm makes much difference in terms of performance, heating, battery?
15'' model has Seagate Momentus 5400.6 500Gb...
What are drives from 15'' and 17'' from 750Gb 5400rpm or 500Gb 7200rpm?
Thanks!
Sorry for my bad english...

Unfortunately the drive mfgrs. don't agree. Both variations carry the same MTBF estimations. Power consumption of the 7200 variant is usually between .1-1.0 watts depending upon the operating state: idle, startup, read, write. Heat generation is also negligible although the 7200 RPM variant may be warmer during heavy usage like doing a backup or restore. However, 7200 RPM drives are faster, and more so than just minor. Realizing the difference, however, depends a lot on the rest of the hardware. Put a fast drive in a USB box and it's slow. Firewire it's faster. But both interfaces are saturated before the drive can reach its potential. If the drive's SATA interface supports 3.0 Gb/s then putting it in a machine whose controller only supports 1.5 Gb/s will prevent the drive from reaching its potential. And this only deals with the basic interface.

I've searched and read 4gb vs 8gb discussions, but still need help.

Hi again,
I've done my due dilligance by searching and reading all discussions related to this matter- but I still have a question.
I've decided on the 13" Air, 15, 256gb. My last decision is the ever so debated 4gb vs 8gb.
From ALL of the discussions I've read (here and elsewhere online) 4gb seems to be enough for the average person, and some have even tested the capacity by opening 16 applications and programs. Most of the responders are also saying 4gb is enough "if you want to keep the computer 2-3 years". Well- what if I'd like mine to last 5-7 years? (I'm working on a 2006 dying MacBook Pro currently with 2gb memory and a 100gb harddrive).
This is a HUGE purchase for me, as I do not have money to spend often on replacing big ticket items. I'd like to NOT spend the extra $136 unless I need to, to make this machine last longer than 3 years.
Thank you! This community has been a great help to me today

Since cost seems to be an issue for you, between the 128 and the 256,....go with the 128 and the 8 GIG of memory,.....such as you have detailed, it would be a better choice given what you have well explained what you want out of you computer. Just pack around a super slim HD 500GB drive in the laptop bag with your air,..they’re only 7mm thick HD, much thinner than the AIR.
I have an 13” I5 128 gig, and have nearly ever APP imaginable installed, and still have 82 Gig of wiggle room for editing, and other space needed for work.
IF ASKED which is the better upgrade choice for the money,….256 upgrade, or the 8GIG of memory, most here will agree that it’s the 8gig of memory.
HD space is extremely cheap (except inside the AIR, its SSD). If you don’t mind packing around a tiny HD, 65$ will get you 1TB, or 500GB in a superslim HD

4gb to 8gb ram: Big help for LR?

I am running LR 4.1 RC2 on my Win7 64-bit 17.3" laptop. Here are the basic specs:
i3-330M 2.26ghz, 4gb, 500gb hd, 17.3" 1600x900 screen, Intel graphics (with latest driver)
Fortunately, I have not had the terrible performance problems that some people report, but it is still somewhat sluggish. Occasionally, even when I am not doing anything the ram usage will go from 450-550mb up to about 2gb for no apparent reason. Also, the cpu usage will go up. It only does this from time to time, but something is going on in the background. Maybe some of the times it is building previews in the background, but that is just a guess. Also, I discovered that any use of luminance NR really slows things down,. Now I wait until the last step before exporting an image to do that so that it doesn't interfere while working on that image in the develop module.
My laptop works well and except for LR is fast enough. I am wondering if going to 8gb would be the biggest bang for the buck change I could make for LR? Often that is the case, but looking at the task manager I usually have quite a bit of memory available, although when LR is really busy like exporting an image to a resized jpeg file the memory of the PC can be up to 95% usage. That drops down though when LR is done. The raw files I am working with are from 16mp and 18mp cameras and I don't do batch processing, just one photo at a time.
This laptop is 2 years old, but still running fine so I would only get a newer one with a faster cpu and more ram if I really thought it would help quite a bit -- or this one develops problems. Changing from 4gb to 8gb though is relatively inexpensive. What are your thoughts? Thank you.

I agree with your statement that 20 GB is probably ample for caching up to 40,000 raw files in LR4 and LR3.6 (see why below). Even using large 21Mp raw files that will hold up to 33,333 images before over-flow (20,000/0.6).
I know this is going off topic, but I'm sure it's of interest. I also thought that LR4.1 PV2012 stores different ACR cache information than LR3.6 PV2010. What is interesting is that the "file size" of LR3.6 PV2010 created ACR cache files are identical in size to LR4.1 P2012 created files. Below is a screen shot showing a purged cache snapshot for three (3) Canon 5D2 MKII 21Mp CR2 raw files processed first in LR3.6, and then in LR4.1 in the same order.
Cache0000000001.dat = Picture 1 in LR3.6 (530KB)
Cache0000000002.dat = Picture 2 in LR3.6 (608KB
Cache0000000003.dat = Picture 3 in LR3.6 (590KB)
Cache0000000004.dat = Picture 1 in LR4.1 (530KB)
Cache0000000005.dat = Picture 2 in LR4.1 (608KB)
Cache0000000006.dat = Picture 3 in LR4.1 (590KB)
What is more interesting is that the ACR cache .dat files are not being updated after making multiple changes to the images in LR3.6 and/or LR4.1 Develop module, only the 1 KB 'Index.dat' file is updated. I had always thought that changes made in the Develop module were updated in the ACR cache, but apparently that's not the case. I went back and hit 'Auto Tone' on each of the pictures, with no change even after zooming in to 100% on each picture. I also tried switching to the Library module and back to the Develop module, hitting 'Reset' on image, and repeating the same 100% viewing. You can see below that the 'Date Created' for the .dat image files is same as the 'Date Modified' (i.e. NOT modified), only the tiny 1KB 'Index.dat' is updated.

4GB+4GB or 8GB+2GB Ram?

Hi,
I'd like to add more RAM to my mid-2012 Macbook Pro (without Retina) and I'm just thinking about these two options.
a) leaving one of my current 2GBs and adding 8GB (it will give me a chance to upgrade it to 16 in the future if needed)
b) changing both 2GBs to 2x 4GB
which solution is better? why? I heard that it's better to have 2 slots with rams from the same producer but I just want to make sure with it. Thank you!

You do not need two of the exact same ram. 2GB and 8GB would be perfectly fine.
2 x 4 GB would be a good choice too but you would only have 8GB RAM. 10GB Ram sounds a lot better.
Or you could spend a lot more and go with 2 x 8 GB totaling you 16GB ram but that would be too expensive and you might not get a big use out of it.
Bottom line, go with 10GB RAM and look at activity monitor to see how much memory you're using, then upgrade to 16GB if your computer requires it.

Does Equium M70 support 4GB or 8GB SDHC card

Could anyone help please?
My laptop reads standard sd cards fine (1gb),
However i want to buy a 4gb or 8gb SDHC card to transfer pictures from my camera onto my laptop and then onto my ipod.
Cant find any info in the manual
Any replies really appreciated
Thanks, Mark

Hi!
The Equium M70 supports only SD cards up to 1GB so SDHC cards will not work.
You can find this information in the user manual. I have checked it and so I know this.
If you dont have the user manual you can download it on the Toshiba website.

Mac mini (mid 2010) RAM upgrade 4GB or 8GB

I have a mid 2010 Mac mini with 2GB of RAM. My question is - Should I upgrade the RAM to 4GB or 8GB?
Thank you, DZetko

It's is better to go for the full 8GB upgrade now,
that way you will not have to upgrade again when OS X and your personal usage demand more.

MacBook Pro. 4GB to 8GB Upgrade.

MacBook Pro. 4GB to 8GB.
Introduction
"Cost-Benefit Analysis"
Features
Boot Time: Is it affected by the upgrade?
Applications
Conclusion
1. Introduction
Greetings, today I am going to discuss the positive and negatives aspects about the
upgrade that many are tempted to perform, before during and after the purchase of an Apple
Personal Computer i.e. MacBook, MacBook Pro, iMac and so on.
I am going to use my first and recently bought MacBook Pro as a "guinea pig" today
by performing and reviewing the upgrade from 4GB of Random-Access Memory (RAM) to 8GB.
I hope you all enjoy it and that this review is useful to you as a guide to aid your decision
to upgrade or not.
Well let's get started shall we?
2. "Cost-Benefit Analysis"
We all know how expensive Apple Computers are for the vast majority of the population,
however I am sure if you are here you do appreciate, like me, the reasons why such cost,
but this is another discussion. Let me focus.
The first option we have right off the bat is to do the upgrade as we purchase the machine,
which is offered to you when you order online, through the phone or buy it directly from an
Apple Store.
I did consider upgrading directly with Apple for the obvious reasons but unfortunately
I wasn't able to this time, the £160.00* upgrade price was a little too high for me, not overpriced,
just a little too high for me. (* or $200.00 USD)
So here is what I have done: I have acquired the part from a third part company which
offered the so called upgrade for £59.99. So I decided to give it a go, before you ask my
warranty will not be voided as RAM and any user replacable parts DO NOT void your
equipment warranty as stated by Apple®.
As you can see the specifications of the product match perfectly what is already inside
a MacBook Pro. But obviously still won't be as good as the 8GB from Apple.
Now to the benefits. rest assured that this upgrade will not be noticed by all of you, and
what I mean by that is: If you only use your Mac for browsing the web or office suites, you do
not need this upgrade, however if you do heavy video or image processing or anything that
requires that little bit extra, you will notice the difference in performance baring in mind that
this model of MacBook Pro has no dedicated graphics card therefore upgrading is a fantastic
way to avoid "paging" and I think for 60 bucks that is a bargain.
3. Features
RAM is constantly used by the system, obviously, serving as temporary storage and
working space for the operating system and its applications.
You may or may not know that most computers use something called "virtual memory"
is a method that consists of a portion of the system's hard drive being set aside for use as
a paging file that extends ram capacity. I.e. 4GB of RAM + 1GB of Paging file gives a system
a total of 5GB of memory available. Obviously upgrading from 4GB to 8GB will enable you to
have more memory without "sacrificing" a part of your hard drive.
RAM is used in numerous others ways on a computer.
3.1 Boot Time: Is it affected by the upgrade?
| To be updated soon. |
3.2 Applications
     | To be updated soon. |
4.0 Conclusion
| To be updated soon. |

3.1 Boot Time: Is it affected by the upgrade?
I did not notice any differences, maybe some miliseconds more or less.
3.2 Applications
        Applications it's a hard one to speak about, it seems to me that the system is coping more easily with tasks that require that little extra. Video and Photo editing and so on.
4.0 Conclusion
         Is it worth it? The truth is for some people yes, for some definitely NOT. If you are looking for that little extra performance just to feel good about it, definitely do it! However if all you do is browse the web and the odd word processing and a few presentations a month, it may not be that beneficial for you. I believe that if you truly want some serious performance, look for the power processing first i.e. Get a 15'' or a 17''; even though they are a bit more expensive they are recommended for video editing and tasks that require high speed and performance.
          In terms of where to buy it from, I found that buying from the third party company Crucial was no different than what would have been from Apple itself, it is EXACTLY the same memory, I compared them both side a side and all the specifications and manufacturers where the same on the 4GB and the 2GB unit.
          Few things though guys:
Please be sure to use a good quality Phillips #00 Screwdriver, you DO NOT want to damage those screws and you want to have ease on opening the machine.
Please only install quality RAM.
Please discharge yourself of any static by wearing a Static Bracelet or touching a metal surface inside the computer.
Please be sure to turn OFF the computer "Shut Down", I repeat do NOT put it to sleep, SHUT IT DOWN.
Please be patient; do not rush things.
          That's it for my adventure Upgrading my MacBook Pro RAM, guys I hope you enjoyed, sorry about the delay and enjoy your 8GB MacBook Pro, I certainly will.
If you have any queries please do not hesitate to contact me.
Walter.

Can I upgrade my RAM from 4GB to 8GB for my MacBook Pro 13(early 2011 2.7GHz)? And how much would it be?

Can I upgrade my RAM from 4GB to 8GB for my MacBook Pro 13(early 2011 2.7GHz)? And how much would it be?

you can upgrade to 16GB if you wish to do so...
average price for 8GB 1333MHz DDR3 is around $50 - $75 depending on the brand.
why not spend $100 and go with 16GB 1333MHz from Crucial or Corsair.
you can get them from Amazon.com or newegg.com
see image below with 16GB Patriot Mac Series 1333MHz for $100.

I want to upgrade my ram from 4GBs to 8GBs, can you help me?

Dear Apple company,
     I have a Macbook 5,4, but I want to upgrade its RAM from 4GBS to 8GBs, can you help me this quest?

This is a customer forum, and not Apple folks. If you wish official or formal Apple assistance, please call Apple directly or visit your local Apple store, or check directly with an Apple reseller.
I don't immediately see a MacBook5,4 around, but I do see a Apple MacBook Pro Core 2 Duo 2.53 GHz 15" model MC118LL/A Mid-2009, and that configuration does reportedly support up to 8 GB of memory per the Apple Specs.
Apple might not stock or offer memory upgrades that far back (but do ask them), though I'd expect various third-party memory providers will likely still have some 4 GB 1066 MHz SO-DIMM DDR3 memory sticks around.
But if yours is really a MacBook5,4 model here — the closest I can find is a MacBook5,2 — then ignore this.

I have an 21.5 Mid 2011 iMac and i want to upgrade my RAM. Currently I have two 2GB and two free slots. Do I have to put in two 2GB in the free slots or can I use two 4GB or 8GB?

You can leave the existing RAM in their current slots and add compatible modules in the empty slots. For best performance, add two of teh same size. Our 2010 iMac 21" shipped with 4GB RAM---two 2GB modules in two of the four slots. I added two 2GB modules to the empty slots and now have 8 GB RAM.
Be sure to order RAM from a trusted Mac-savvy RAM vendor. Some vendors thing a Mac is a hamburger. For over a decade I've bought all our Mac RAM (and we have 18 Macs in teh family!) from one vendor:

The link is to the proper RAM for your Mac.
Crucial.com is also a trusted vendor.

Can I upgrade the ram memory of my Macbook air from 4gb to 8gb?

Anybody knows if I can upgrade the ram memory of a Macbook Air from 4gb to 8gb?

Welcome to Apple Support Communities
The memory in the MacBook Air is soldered onto the logic board, so you can't upgrade RAM after buying your computer. It's important to buy your MacBook Air with the amount of memory you will use because you won't be able to install more RAM

N91 4GB/N91 8GB

Is Nokia going to release any more firmware updates for N91 4GB/N91 8GB? coz dey both have some bugs still left that needs eliminating on these firmwares.
If you find my post useful then click on
Kudos!Nokia N96 (v20.050 / RM-247)
www.shaysoft.net | Competitions!

Nope, besides Nokia stopped production of N91/8GB. It is natural newer FW for N91 is abandoned. The last was 2.20.008 and it was released AGES ago-and the phone is still buggy. I gotta disagree the N91 8GB is still as buggy as N91. It has 3.10 and is very stable on my N91 8GB.
