If you're not doing anything crazy with them, you probably won't be able to kill your average MLC/TLC SSD.
Let's say you write 20 GB to your SSD every day. The SSDs mentioned in the article have a lifetime of 72 TB, which means you can write 20 GB daily for more than 10 years. Also, 72 TB is probably a pretty pessimistic estimate.
That being said, if you do anything I/O-intensive (write-heavy databases, anything with lots of small write operations, ...), YMMV. That's why "enterprise" SSDs are still unbelievably expensive - quite often they use SLC technology (though there are more and more server MLCs) and they usually have way more "spare" cells which are used to replace other cells killed by too many writes.
- tobylane 14y agoEnterprise quality seems to mean a different quality improvement each time. Is there any realistic point in average heavy desktop users sticking to SLC?
- pfg 14y agoCan't think of a reason. SLC is a bit faster at writes, but a lot of new MLC SSDs are able to fully saturate SATA 6Gb/s, so there's really no point in going any faster. If you're really worried about write endurance, stick to MLCs with a lot of spare cells (I think Intel is a good choice there).
