[QUOTE="RonD, post: 1042415, member: 117536"] All SSD have concerns with how many times you can erase/write the same data blocks and a large number 10,000-100,000 erase/writes to the same block(s) can degrade the reliability of the high traffic data blocks. Since timeshift buffers sees a lots of writes they are more likely to see problems and I would not recommend using a SSD for timeshifting. A SSD used for the OS disk is less likely to see this problem since a lot of the data is static, write once or only write a few times. But there can be "hot spots" that see a lot of writes to the same data blocks. The SSD internal controllers try to detect this do "wear leveling" to spread the writes over the SSD to help with this problem.
