IMO, one interesting thing is about the native support for SSDs and elimination of long known & trustworthy HDDs. Clearly the sign of things happening!!
SSDs, HHDs: Could I get some clarification on those TLAs? :)
Solid-state drives and hard-disk drives. HDDs are mechanical devices with spinning platters. SSDs have no moving parts; it's all silicon. (HHD is not what he mentioned, but it's a hybrid hard drive; solid state cache with normal disk drives.)
SSD = Solid State Device (Drive)
HDD = Hard Disk Drive
