Hi,
So I've recently been building me a NAS for home use (FreeNAS with 4 disks in a microserver, zfs raidz2).
The drives have mostly been accumulated from different batches, well 2 share the same batch it seems.
Problem seems to be that when putting the disks through various burn in tests and benchmarking that not all drives are created equal!
Two in terms of I/Ops, read/writes etc are the same. One is a tad bit slower. However the last drive is a good bit slower to spin up and in general is about 5 - 7% slower than the other 3. (As well as being audible above the others when writing..).
My question being, would any Hard disk manufacturer accept an RMA on the grounds that the drive is slower than expected? If so, is there a % slower it has to be than the model average? Or would there HAVE to fail a smart test?
FYI the drives are WD red pro's for anyone interested.
Thanks,
Flakey
