10,000 RPM

Recommended Posts

I put 3 Seagate SCSi 10K RPM drives in a dual Pentium Pro 233 server a few months ago, RAID 5 config. It was very fast, but I don't know if it's worth it for a work(play)station. Are there 10K IDE drives now? If so, unless the data transfer rate can sustain >40Mb/sec, I'd pass.

the fastest drives out there now are the seagate cheetah 15K. that is 15000rpms!!!! scsi is an expensive interface, these drives require the ultra160 scsi which sell for at least 215 a card. as for 10k ide drives, NO. not now anyway. fastest drives are scsi. if you want cheap speed, go for ide raid using ibm deskstar 75gxp and a promise ultra100 raid controller.

ok i need a bit more info about raid, hoping you guys can help me out.

i know raid stands for redundant array of inexpensive drives, or at least i think it's that.

but i don't really know about its actual benefits and how it can be faster than ide.

any of you guys care to enlighten me?

Well, you can set up the drives in several formats.

"0" lets you stripe 2 drives, alternating putting chunks of data on one then the other really fast, which I think allows a steady stream of data to be recorded as opposed to intermittant recording with just one drive.

"1" allows you to have one drive as the primary and the second as a backup, so the second just copies the first one exactly. There's no speed gain here.

"0+1" allows both the striping of 2 discs and a backup for each striped disc. Obviously, you need 4 HD's (or more).

That's about all I know about RAID. I don't know exactly how much performance gain you would get.
