Forinstance, if data is read from the device during a garbage collection operation, the M550 will protect that data
insteadof introducing corruption of old data. This is listed as "power loss protection" on the spec sheet but it's not
thelevel of protection that people on this list would expect from a drive)

Yes - the MX200 board (see):

looks to have the same sort of capacitors that the M550 uses, so not
ideal for db or transaction logs!
