Many TLC drives have SLC cache so if you limit usage of the drive you may effectively use it in SLC-only mode. This does not say anything about its endurance however. If you want endurance, better mirror your data to HDD.
- wtallis 4y agoIf you want to use a drive as pure SLC, you're probably better off buying a QLC drive than a TLC drive. QLC drives are more reliant on SLC caching and tend to be more reluctant to migrate data from SLC to QLC when it isn't absolutely necessary.
- efreak 4y agoShow me software that can mirror an SSD to HDD in realtime without the "backup" being affected by the slower write speeds. I was looking for a way to do this a few years ago, and couldn't find anything. I'd be very happy if I could pull my SSD out, change my boot drive, and boot into my existing OS without any issues. My understanding is that existing solutions for this delay write confirmation until both drives are complete, negating the speed advantage of the SSD.
