Hi. I have a software MDRAID 10 that I set up in 2010. It has 6 disks. One has blown. Unfortunately the exact disks I used are no longer made. So I need to figure out what an acceptable replacement model will be to rebuild the array.

the drives I used were

Seagate Barracuda 1TB 7200RPM 32MB SATA2 ST3000528AS

So I need to buy a drive that is as similar as humanly possible to that.

It's a crappy, unstable array which is my fault. I partitioned over a cylinder boundary i think. so it's unusually sensitive. There is no time to move the data and make a completely new system at the moment.

So I have to stick with what I've got for now, but I'm not sure how to figure out what drive to get.

thanks

as you say it's sata3 and has a different cache size.

but it has the same latency

it would be a problem possibly if my motherboard supports sata3 since then the new drive might transfer data twice as fast as the 5 existing drives.

I basically have no idea whatsoever.

there is this:

but the manufacuterer is different.

if the sata3 and cache size shouldn't destablise the RAID I'm guessing it's best to get the drive you suggest. I expect it's basically the same physical drive with different electronics.

what do you think?
