Hey Everybody, So I'm working on first build for a NAS/SAN and I'm in the final stages. Been doing a lot of reading on NL-SAS and brands of hd's, but it seems that HGST is coming out on top for reliability? Western Digital owns Hitachi (HGST) but I'm kind of torn now that I know that, hopefully they have not changed processes. There was a report that came out related to the drive reliability, https://www.backblaze.com/blog/what-hard-drive-should-i-buy/ that also made me question going with Seagate and WD.
MTBF on the HGST are higher then all at 2,000,000 versus 1,200,000.
Primary use of the system will be:
VmWare Datastores via HBA
I'm running HBA's between ESX and storage and HBA internally. Also, network is going to be 10 GB.
So my question is would you go with WD SE/RE, HGST (7K4000), or Seagate (ES3) and would you bother with NL-SAS when hooking up to a backplane on a supermicro chassis
Also, does cache being 32MB on WD RE drive make much of difference when compared to the Seagate ES3 drives with 128MB of cache?
