So I have an HP Proliant DL380 Gen9 that came with 5x6TB HP SAS drives (MB6000JVYZD) in it.
Naturally I used them since they seemed to be in good enough condition, and I set them up as a RAID6 just to be safe.
So now it's a couple of years later and one of the drives seems to be failing, so I need to replace it.
A brand new Ultrastar costs about 230€ here, ~~an EXOS about 250€,~~ while a MB6000JVYZD goes for about 300€ on ebay (brand new according to the shop).
At this point I'm leaning towards getting the original drive. But for future reference, could I replace a faulty drive with another brand?
I know that one potential problem is if for example the new drive has fewer sectors than the old ones. But are mismatches common? How could I check before ordering? Are they possible within the same SKU?
~~Then again, an 8TB EXOS also goes for 250€ for some reason... So I could just get that and waste 2TBs but play it safe.~~
EDIT: I just realized that EXOS drives are SATA, which I think disqualifies them.
Thoughts? Thanks!
