SSA Drawer 10K with 15K disks

[bonsky]

i have D40 with one array RAID 5 composed of 4 disks 36GB with 15K rpm each. Now, one of disk failed and unfortunately we dont have any disk available for replacement but 36Gb 10K rpm ssa disk. Can i used this one to replaced the faulty one. My understanding is that theoretically, this can be done but would there be any side effects on top of performance degradation?
thanks!

You may want to make sure that all the disks have compatible microcode before putting them in the same loop:

We have the inverse situation, with 10K drives being replaced under out service contract by 15K drives, either because the CEs don't check, or that's all they have for replacement stock.

We haven't seen any side effects. Check the microcode first, like p5wizard said, but once that's compatible you shouldn't see anything besides the 1/8th performance hit (and might not even see that, depending on how disk bound you already are).
