Quantum Atlas 10K II & Adaptec 29160 Review (Page 1/4)

If you're building a high-end PC that you want to perform at extreme levels in every way possible, SCSI has to be included. IDE is nice for a cheap PC, but if you want that same amazing performance that high-end servers utilize, SCSI is basically the only option.

SCSI is expensive. That's a well known fact. But is it worth the money? Hopefully this review will answer that question. As I take a look at Quantum's Atlas 10K II drive, keep in mind that I'm a gamer. I use my PC for just about anything, but the majority of entertainment I get from my PC is from gaming.

The Drive, The Card.

I am usually an IDE guy. In fact, the first SCSI drive I've ever installed on my own PC was this drive. It wasn't as if I hadn't dealt with SCSI before; it's just that I never thought it was worth the money or that I'd make good use of a SCSI card and drive(s) in my own PC. So what SCSI card was worthy enough to be teamed up with this monster of a hard drive; the Quantum Atlas 10K II 36.7 GB? Well I knew it had to come from Adaptec. And the best option at the time (thanks to Ultra160 SCSI support of the hard drive) was Adaptec's 29160 SCSI card.
