SSD for Windows - Bad Idea
SSD drives are flash based and have upper limits on writing to any particular region on the disk. "Wear leveling" algorithms built-in to the SSD mitigate this to some extent. Problem is, Windows operating systems, their owners and clueless suppliers, install all kinds of crapware which may have logging functions - that can't be turned off. From spyware-like process monitors to freeware firewalls, these logging processes drive the little blinking LED mad and can use up the limited life of a SSD. Perhaps the larger problem is that for many PCs they can never be "Green" again. One of the largest uses of electrical power in a PC goes to the disk drive. On many PCs today, because of such logging activities, the hard disk drive never shuts down. This means the power-supply never goes into standby. This means the PC uses (at least) 100x more energy than it would have without the crapware.
How many PCs in your business burning a hole in your pocket?
