So, I have Crucial MX500 SSD, and on their spec sheet, the SSD Endurance TBW is 180TB
Crystal Disk Info says the health is at 33% Health, despite Total Host Writes being 54039 GB (30% of specified SSD endurance TBW of 180TB)
So is their specified endurance wrong, is the Total Host Writes data in Crystal Disk Info misleading or wrong, or is there more things that go into determining the “health” of an SSD besides Total Bytes Written? Or could it be that I mistreated the SSD causing its health to get worse?
Ok. Thanks. The drive looks fine. The 33% health seems to come from the average block erase count. This is the most expensive operation on SSDs.
Why does it increase faster? Because blocks are written partially. Worst case is that if you write 1 Byte to a block and then 1 Byte into same block, it would need 1 block erase (usually a block is 128 kB, not 4 kB like HDDs have).
Your SSD is very busy. You should review what is going on on your system.
