Mac Pro :: Most Efficient SATA / RAM Configuration For Speed
Sep 15, 2008
I am getting heavily into 3D animation and modelling, and as such have purchased a 2.8Ghz 2008 Mac Pro 8-core. I currently have raid-0 my two 320Gb hard disks; I know it's not very secure, but I'm just in the setting up phase right now, so that doesn't matter. My question is this; is there a MASSIVE performance increase, when upgrading from the stock 2x1Gb FBDIMM sticks, to, say 16Gb in 2Gb sticks, or 32Gb in 4Gb sticks?. What is most noticable? Finally, what raid configuration is optimal for both speed and peace of mind?.

I'm looking to upgrade my hard drive, cloning everything over to the new one via external adapter. Are there any adapters out there that use FireWire 800 so I can get the best speed possible?

I have a Power Mac 2.3Ghz (see spec in sig) with the standard 250GB Maxtor 6B25050 hard drive. I was wondering, how I could increase the speed of the computer? If I upgrade the hard drive to something like a Western Digital Raptor X 150GB 10kRPM SATA drive would this provide any performance increase over the standard disk? Memory-wise I never have any "page outs", so I understand that a memory upgrade will not increase the speed of my computer.

I have a 13" MacBook Pro 2011, 2.3gHz, 320GB. What connector does it have? And would SATA still work with my laptop? One more question, what are the exact dimensions of the hard disk drive bay in my laptop, the manual only says 2.5".

ive put 4 of the hitachi 1tbs in my new mac pro.. and i really want to do Raid on them eventually.. and buy the pricey apple raid card.. i'll do it.. but speed wise:
How fast is a Sata connection straight from HD>Motherboard... ~75mb/s?
Is the Raid 5 config with all those drives much faster... around ~110mb/s?
Do you know if there is anyway to get a 5th drive into the raid 5 array? using the ODD space.. or some externals too... i need as much as space as possible...
And boot camp wont work with raid card anymore? I was thinking to have the startup disc be a raptor to increase speed on the apps, how would it integrate with the raid card, etc

Im considering purchasing a higher capacity internal hardrive around the 750Gb/1Tb mark. However my macbook is the early 2008 model, and it seems the majority of hardrives are SATA II, having speeds of 3Gbt, which my mother board may not be capable of (apparently only 1.5Gbt) From researching and reading some reviews of others who have purchased internal drives on Amazon UK, some have had difficulty due to this problem, but have been able to fix the issue with a firmware update reducing SATA II drive speeds to 1.5Gbt.
Questions I have: Do all SATA / SATA II internal hardrives need a firmware update if replacing on to a new computer?(If so, would I need to look for a specific firmware update for the specific drive I intend on buying? And if you're in the knowledge would you mind posting links to these updates?)What is the process of updating the firmware i.e. would I need to put firmware on external usb hardrive 1st, then upload it to macbook after installing new internal drive (if it boots up my OS that is) etc. Would a 'hybrid' (disk+solid state) drive be compatible with a macbook as old as mine?Do I need to update my operating system to OS X Lion first, or can it be done after installing the drive?

I'm looking for a new HD to replace the original, now failing Maxtor drive in my G5 tower (1.8 Ghz dual processor, purchased in Aug. 2004), and have just about settled on the Western Digital Caviar SE16 series. It seems there are two types -- SATA and SATA II -- and I'm not sure about how to make a decision on which particular WD model to buy.
Will either type work in my machine? Or would the SATA II have potential compatibility problems? I read somewhere in these forums that someone with a G5 had bought an SATA II drive, and it wouldn't run with his system. (He said he had to reset some jumper switches to reduce the transfer rate of the drive ??, but now I'm told elsewhere that SATA drives don't have jumper switches.

I've got a Mac Pro 2008 with four internal SATA drives which I back up with Deja Vu (don't care for Time Machine) on to four SATA drives housed in an Icy Dock. I back up all the key folders from Drive 1-Internal (users, apps, library, system, along with some other folders) but I do not have an OS installed on this drive. If my Drive 1-Internal fails, the option is to boot an OS from a DVD or USB drive and do a clean install onto an empty drive. I can then copy my backed up folders onto the newly-formatted drive.
The first issue is that you have to have a hard disk at your disposal that is either new or you're willing to wipe clean. The second concern is that it takes more time to do a clean install and transfer backed up files than if you had a backup drive with an OS installed that you could boot from.
What are the advantages of installing an OS on Drive 1-External? Doing this would mean having to run software updates on two separate drives? Apart from decreasing the downtime involved to reformat a new drive, isn't it preferable to do a clean install on the new main hard disk? Opinions?

I just received my new mac and few days ago I had found a link in one of the threads about how to reinstall the oSX without all the unnecessary crap, in order to reduce the size of it.
I DON'T REMEMBER THE LINK...I spent hours and hours in the forum but I didn't find it...anybody knows about that article?

I have ordered my first Mac, a Mini 2.66Ghz and I will put a Intel X25-M SSD in the machine to speed it up further. I hope I will be pleased with it
However, the question I encountered was whether the sata connection in the Mini is SATA-150 or SATA-300? Does anyone know?

I am now shopping for a new internal HD of MAC G5; previous HD died. I have decided on a Western Digital and was about to order one when I became alarmed by the SATA II listings. Is there a difference between SATA and SATAII that I should be concerned about the comptability? Don't want to get it and find out it doesn't work!

I'm running two of these enclosures: [URL] each with 2x2TB drives in RAID0 (i.e. 4TB per enclosure). I use one 4TB array for my user files, and the other for TimeMachine. My user array is connected via FW800, my question is - is it more efficient to connect the other (TM) array via USB2 or via daisy chained FW800? The enclosures use the Oxford 934DSb chipset, which is capable of saturating the FW bus, so thats 100MBps. As i understand it very few interfaces are capable of saturating a USB2 bus such that practically speaking even FW400 gives greater real-world throughput than USB2, despite the 60Mbps difference in spec.
Since one is a TM volume, when backing up from the user array to the TM array will the data have to pass through the computer's controller? It definitely will if it's FW800 -> USB2, but will it have to if it's daisy chained FW800? I'm told this might not be the case as some FW controllers support P2P communication but i can't find too much info about it. Even if there is P2P support the OS needs to know the progress of file transfers and so forth so can it do this even if the drives are transferring via P2P or can it only monitor that sort of thing if the data goes through it's controller? Essentially is it up to the OS or the controller to select the optimal route for data? If it's up to the OS does Mac OS support FW P2P? That said, even if the data does have to go to the computer from one array and back through the daisy chain to the other array, is it still practically faster than the USB2 route?

Sorry for the title but I couldn't think of anything better. Hopefully I'll be able to explain my problem. I have a MPR 2.53 ghz, 4 gig ram, I'm using Safari 4.04. I am using the WIFI at a guesthouse in Thailand (but I had the same issue in China, Vietnam ...). I ran a speed test and it said download 7mb/sec and upload about 1mb/sec. I have an "app" that says bandwidth in 1.3kb/sec out 1.0kbs. I thought maybe it was Safari so I downloaded and installed Firefox. firefox gives me similar speeds. When I downloaded Firefox though I had a download speed of over 1mb/sec. But as soon as it finished downloading the speed went back to around 1kb/sec. I have rebooted my MBP many times. I did some Google searches but didn't find anything helpful.

I am interested in adding a webcam to my desktop Imac (power pc)- Isight is no longer available- an option that I found is the Ecamm Image- but apparently it is USB and not firewire and it will only run with high speed usb- how do I know which type is on my computer? I checked system profiler but quite frankly wasn't sure of the designations.. does anyone have any experience with this camera, by the way? is USB 2.0 by definition "High Speed"?

I have a WDS local network at my house. I use a Airport Extreme in my main part of the house and a Airport Express for my back part of the house i.e. the backyard. Now every two weeks or so my internet speed through my Airport Express slows down about half the speed but when I am connected trough the Airport Extreme my speed is normal. I know this because I test my connection very often. Now when I want the Airport Express to get back up to speed I have to unplug, and plug it back in. Then after awhile it starts to slow down again in a time period of two weeks or so.

Have an Extreme base stations and express repeater connected to my DSL services. On my primary iMac connected via ethernet I get 5.25MBps speed. The speed on this computer is always constant. On the remote MacPro I get anywhere from 1.5MBps to 5MPps speed within a half hour of testing.

I'm using Data Rescue III on a USB powered hard drive with and it's taking a very long time with my iMac G5... It says 42,291 hours remaining (about 5 years) If I did it on my Mac Pro would it go faster, or is the recovery speed based on the hard drive speed?

i have a 1.5 Mbps AT&T DSL connection, and multiple speed tests show a download speed of 1.2 Mbps (and 200 Kbps upload). when i download files, such as software updates from Apple, various podcasts, and even Silverlight from Microshaft, the speed is always between 140 - 160 Kbps. i contacted AT&T, and the rep said it was because of buffering by the servers i was receiving the files from. is this a reasonable explanation? is this an accurate use of the term "buffering"?
