What's the fastest Ultra ATA drive under $200? (The new IBM Deskstar 75GXP goes up against
Seagate, Quantum, Maxtor and Western Digital models.)
I saw some impressive numbers posted by other sites for the newest Deskstar 75GXP drive from IBM. I had to see if I could get the same numbers and if it was the new Ultra ATA champ:
The new IBM Deskstar 75GXP drive clearly beat out the others in my favorite "real world" test. Duplicating the three large files forces the drive to read and write simultaneously. That's why I show it first. I believe it before I believe benchmarks.
Some readers wanted to see how fast these drives can duplicate hundreds of documents. As you can see, it takes longer than three big documents. However, IBM 75GXP wins again.
But if I used a benchmark, my favorite is ATTO's ExpressPro-Tools benchtest. Below are those results for your edification.
And the new champ is...
The IBM Deskstar 75GXP. Awesome drive!
Where to buy...
Best prices I've found are at BUY.COM -- IBM Deskstar 75GXP I tested was the 30GB which sells for $196. It comes in various sizes from the 15GB for $112 all the way up to the 75GB for $519. $20 off on any purchase over $100 before June 30th at Buy.com
If you are a Maxtor fan, BUY.COM has the DiamondMax Plus 30GB 7200 RPM going for $193. They also have the popular 40GB for $249. CNET SHOPPER shows the 40GB going for as little as $222.
The Seagate Barracuda ATA II was $149 for the 20GB (Onvia). The 30GB version is $189 (also Onvia). FREE SHIPPING!

Questions & Answers
Which drive was the quietest?
The IBM Deskstar 75GXP by far.
I have a Beige G3/266 Desktop. If I buy one of these drives, will it achieve 20+ MB/sec read/write rates like the G4?
Pretty close, but only if you add an Ultra ATA/66 PCI controller card. The internal IDE interface is too slow. The only Ultra ATA/66 cards available at this writing are the Acard and the TurboMax. According to MacFixit, some new cards are expected at the NY MacWorld Expo. I would wait to see what shakes out of the Expo before you buy one.
What about the "PCI" Power Mac (7500, 9600, etc.)?
Your read speed will be in the 20+ range but your write speed maxes out at 15MB/sec due to bus speed constraints. But it's still better than 5 or 10MB/sec.
I heard you can use SoftRAID to create a striped array of fast Ultra ATA drives. I thought that only worked with SCSI drives.
It's a cheat. If you use an Ultra ATA/66 PCI controller card, it fools the Mac into thinking it's a SCSI bus. I've observed varied speed results depending on what Power Mac I'm using. For example, the G4/400 Yikes achieved 48MB/sec sustained write speed with one controller card and dual cables. Same setup on a G4/400 Sawtooth hit the wall at 31MB/sec. Even with dual cards, the Sawtooth maxed out at 43MB/sec sustained write. (Both achieved 64MB/sec sustained read.)
Why would I want one of these drives instead of what Apple ships with their current G4 line?
All 5 "third party" drives beat the Western Digital Expert 20Gig that ships with the mid level G4 Sawtooth. That's why, if you are doing a "build to order" G4 from Apple, I recommend buying the cheapest, smallest drive (10 gig) and ordering a third party drive to replace it. That is a cheaper way to go than buying Apple's upgrade to the 20 gig plus it gives you a faster drive.
How do I format one of these faster drives? Aren't they made for Windows PC's?
All 5 third party drives can be formatted with Apple Hard Drive Setup utility and be designated Startup Disk. That's the beauty of IDE. Even if you are running the drive using an Ultra ATA controller, you can make it the Startup Disk.
