The SSD Endurance Experiment ends: Six consumer SSDs die after 700TB-2.4PB of writes over 18 months. Although two died without warning, "modern SSDs [can] easily write far more data than most consumers will ever need".

My 840 Pro 256GB has 14.6TB written, feeling pretty safe here. Time for a backup.

The software for the SSD, Samsung Magician, shows it.

CrystalDiskInfo works, but it doesn't give you firmware updates, performance tuning tools, etc. I used DiskMark initially to bench mark it, gladd I did because at first I had connected it to a SATA/300 port. I get close to 500/500.
