Hi, Just to revisit this one last time . . . Is the issue only with the SandForce SF-2281 in the Kingston E50? Or are all SandForce controllers considered dodgy, including the SF-2582 in the Kingston E100 and a few other manufacturer's enterprise SSDs? Thanks, Simon. On 16/05/14 22:30, Carlos M.

The replacement is the 1200 series which are more 2x the price but have a SAS 12gbps interface. You can still find the 600's out there at around $300/drive. Still a very good price based on specs and backed by the reviews. > > The Kingston E100's have a DWPD rating of 11 at the 100/200GB capacity, and similar specs to the S3700's (400GB), but more expensive per GB & PBW than the intel S3700, so I'd probably stick with the S3700s. > > Carlos M.
