Is anyone trying Ceph clusters containing larger (4-8TB) SSD drives? 8TB SSDs are described here ( https://www.anandtech.com/show/16136/qlc-8tb-ssd-review-samsung-870-qvo-sabrent-rocket-q ) and make use QLC NAND flash memory to reach the costs and capacity. Currently, the 8TB Samsung 870 SSD is $800/ea at some online retail stores. SATA form-factor SSDs can reach read/write rates of 560/520 MB/s, while not as great as nVME drives is still a multiple faster than 7200 RPM drives. SSDs now appear to have much lower failure rates than HDs in 2021 ( https://www.techspot.com/news/89590-backblaze-latest-storage-reliability-figures-add-ssd-boot.html ). Are there any major caveats to considering working with larger SSDs for data pools?
