I need to replace the first 16 drives in our newly inherited san. They are 300G 10K 2.5 SAS drives and I would like to replace them with the 1.2T version. I am seeing some priced around 450-500$ and then some at 700$+. Looking at HP’s specs I see two groups, the cheaper seems to be HP 1.2TB 6G SAS 10K rpm SFF (2.5-inch) Dual Port Enterprise 3yr Warranty Hard Drive 718160-B21 while the more expensive seems to be HP MSA 1.2TB 6G SAS 10K 2.5in Dual Port Enterprise 3yr Warranty Hard Disk Drive E7W47A or compatibles.
Anyone know what the difference is other than the first is listed as PL and the second as MSA?
