Samsung gets all the press nowadays because their SSD's are the
highest performing... but I am in IT and I buy these because they
are a good value, and reliable. The Crucial/Micron brand SSD's have
been made in the same factory, and they both offer rudimentary
power protection. This doesn't protect writes that were being made
when you lost power, but it does offer some protection on the rest
of the data.
Other brands without power protection can suffer major file system
damage if power fails during use. I put these in OEM laptops (and
MX200's before this one), where people run out of batteries, and
I've yet to have a serious failures.
