Mixing internal SCSI hard-drives with different rpm speeds.

One of the Seagate Cheetah SCSI 10K rpm RAID drives failed on a server and apparently new 10K's are not available anymore.

Can I replace a 10K with a 15K drive? Size would be the same at 146GB.

I think generally you'd have to be sure that the replacement drive is at least as fast (which wouldn't be a problem with a 15K drive) and at least as large in terms of LBAs...

Check the product manuals for the comparative LBAs for each drive. Then ask your RAID controller manufacturer whether that would work.

Excuse my ignorance/non-expertise...... what are the LBA's please?

thanks

No problem - it's Logical Block Addressing, the actual measure of capacity.

Search LBA and Logical Block Addressing in the product manual for each drive.
