Can you recommend a specific brand of PCIe flash card? How reliable are they?

We are running these in OnMetal: http://www.lsi.com/products/flash-accelerators/pages/nytro-w...

Reliability is similar to an SSD. The underlying storage tech is basically the same: some flash chips, with a controller that handles wear leveling and so on. Just that instead of running operations through a SATA controller it uses the PCIe bus, which offers higher bandwidth and lower latency.

Interestingly, Apple is shipping PCIe flash in all (I think) of their latest laptops.

Oh, I see, just plain SSDs with PCIe instead of SATA. Yes, that seems logical.
