Made by Red Hat.
The important thing to note: the FUD about discard and claims of poor
performance are against engineering sample SSDs - not retail SSDs. My
retail Intel G2 SSDs have no issues with discard.
Hi Michael,
The testing we have done on recent kernels does show a wide variance in
performance across *shipping* drives, not just samples.
That is why we default discard to "off" in upstream kernels still :)
