whats an scsi hard drive?
- Thread starter King-C
- Start date
scsi was a competitor interface to IDE/ATAPI interface, and it's a serial interface, similar to SATA, but rather than focus the bandwidth toward a single drive, creating as fast of a connection as possible, it allowed you to link dozens of drives together off a single controller.
it was primarily used for servers, and the first RAID arrays were SCSI.
Now there's a new version of scsi called SAS, which is supposed to compete with SATA, which allows up to ~250 15,000rpm drives to be chained together. So although no single drive has as fast a data transfer rate as SATA, you can link TONS of drives together, to be accessing HUNDREDS of different files/segments at one time. And 15,000rpm drives have the fastest seek times of any hard drive to date.

what about that I saw the rpms were crazy can this be used or is no good?????????

yes, of course
but understand that SCSI drives are for very specific purposes
yes, that drive has a 15,000rpm platter speed
but that means several things
1st of all, it's ****ing hella-expensive for the size. You could get a 500GB 7200 SATA drive for that, and it's only 40GB.
2nd, it's gonna have INSANELY fast seek times, but CRAP peak data transfer rates. It's like a gigantic flash drive.
3rd, have you looked at the price of controller cards, yet?

there's two cheaper ones on newegg, but they're pcmia or whatever for laptops, and are only 2MB/s

ya, a regular hard drive
it doesn't matter, the fastest hard drive in the world might save you 5-10 seconds of loading time
once you're in the middle of a game, everything's being loaded from the GPU's onboard video memory, and the ram
the only things that will still be loaded from the hard drive are extensions to the map as you move around, which are buffered FAR in advance, and are not time intensive.
if you're seting up a gaming machine, you've got many other more important things to spend all your money on than a hard drive
spend $130 on a 500GB 7200rpm SATA, and be done with it.
if you need more speed down the line, buy a 2nd identical hard drive, and run them in a RAID-0
