Can someone please tell me when it comes to total bytes written (TBW) on an SSD, which one of these SMART readings is more relevant when it comes to endurance: compressed NAND writes or uncompressed host writes?
I’m assuming the SSD has a Sandforce controller. If so, compressed NAND writes is the better guide.
[QUOTE=Dee;2780989]I’m assuming the SSD has a Sandforce controller. If so, compressed NAND writes is the better guide.[/QUOTE]Thanks Dee for the reply. Yes, you are right the SSD that I have is based on the SandForce SF-2281 controller. So this means that if an SSD has a SanForce SF-2281 controller with a TBW life expectancy of about 300 TB then Compressed NAND writes would have to be deducted from the life expectancy of 300 TB, not the “Uncompressed Host Writes” or the “Lifetime Writes from Host”. Am I right?
Yes, that is correct.
