10k hard drive

[AJFILMS]

I wanted to get a raid card for my computer, but to save money I was going to buy a 3gbps raid card instead of a 6gbps one. But would a 3gbps one be a bottle neck for a 10k sas drive?

Take a look at the specsheet for the drive. Can it exceed 300Mbps?

ok i found a spec sheet and its 375mb/s

No a 3Gbps RAID card will be fine. A 10K disk sustained transfer rate isn't that high, 150 MB/s-180MB/s, and the actual reason to buy them is lower latency for more IOPs which isn't bandwidth constrained.

 

That 375MB/s is it's cache burst speed and can only do that for less than a second.

ok thankyou also a second question and im guessing this varies from card to card, but do most cards support hotswapping drives? do you know?

Yes all SAS cards.

Have you actually got a PCI-X slot? I suspect you don't since anything with those is extremely old.

 

Any one of these would work (Not sorted by price):

All above mentioned cards will also need SFF-8087 to 4 SATA cables if you don't have a SAS HDD back-plane/cage. If you do have a back-plane you'll need SFF-8087 to SFF-8087 or SFF-8087 to SFF-8643 depending on type.

It would work only if you have a PCI-X slot. Since you haven't told your motherboard model, we can't say.

What's the motherboard you are going to be putting it in to?

Nice, yes the card you got will work then. That board has 2 PCI-X slots.
