Hot potatoes: Solid state drives can only write a limited amount of data over their lifetime, which is indicative of the “health” of each drive. A disturbing number of recent reports of Samsung’s 990 Pro SSD losing health have surfaced too quickly, and Samsung has been slow to address them.
Users have reported faster than normal health degradation of Samsung 990 Pro SSDs for about a month. No one seems to have pinpointed the cause, which affects all drive sizes. Samsung only recently opened an investigation into this.
multiple users on reddit And Overclock dot net He says storage utility software is reporting alarmingly low health numbers for 990 of its positives and massive amounts of data written after only a few weeks of use. Various utilities such as CrystalDiscInfo and Samsung Magician suggest that the same stats move more quickly.
Samsung warranty wrappers 990 Pro for up to five years or 600 terabytes written (TBW) for the 1-TB model and 1,200 TB for the 2-TB model, starting at 100 percent health on initial install. Magician and CrystalDiscInfo told one user that a 2TB SSD had only 93 percent health left despite only writing about 7TB, which puts them at over 99 percent health. Others report similar health ratings despite writing less.

At least one user drive loses about one percent per week, which could kill an SSD in 18 months. Another lost three percent in one day. A bad example on Twitter shows a CrystalDiscInfo results screen with 64 percent remaining after only 2TB of writes (above).
Newin Ruby Khan faced problem and I sent his SSD to Samsung, hoping the techs will reveal the root cause. Samsung put the drive back in after a factory reset, which should have brought it back to 100 percent health, but it only had 94 percent. Samsung offered to replace the SSD and take Kahn to try to replicate the problem.
It is unclear whether the problem stems from software or hardware. There may be a bug in how SSDs report their values to health checks. The only common denominator among the affected drives is that they are all Windows OS drives, so the problem could also be an operating system error. Hopefully, Samsung will make an official public statement soon.
