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.

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.

Thanks for bringing that to my attention.
It looks very good until one gets to the Sandforce controller in the specs.
As in, if you're OK with occasional massive spikes in latency, go for
it (same for the Intel 530).
If you prefer consistent perfomance, avoid.
Cool, that saves me from burning £100 unnecessarily. Thanks.
I've one more suggestion before I just buy an Intel DC S3500 . . .
Seagate 600 Pro 100GB
520/300 Sequential Read/Write
80k/20k Random 4k Read/Write IOPS
Power Loss Protection
280/650TB endurance (two figures, weird, but both high) 5yr warranty and
not a bad price

It's not a SandForce controller :) It's a LAMD LM87800.
Cheers,
Simon.
