The most exciting recent development in SSDs (until 3DXpoint is released), is bypassing the SATA interface, connecting drives straight into the PCIe bus (no more expensive raid controllers). Just a shame hardly any server motherboards come with M.2 slots right now.<p>The 4x speed increase and lower CPU overhead means it is now possible to move RAM only applications (for instance in-memory databases) to SSDs, keeping only the indexes in memory. Yeah, we&#x27;ve been going that way for a while, just seems we&#x27;ve come a long way from expensive Sun e6500&#x27;s I was working with in just over a decade ago.
