On older machines we use Kingston SV300 plain SATA SSDs. No special problems to report. 0 failures. SMART attributes make sense. (Generally, Kingston (Toshiba) SSDs have good reliability, out of two pagesful of SSDs, in almost 5 years only 2 failures, the very first SSD (SV100) bricked by firmware update, one SV300 turned into a space heater (if powered, heats to more than 50 degC, does not work, internal short in the controller chip. by luck no flames, no fire). > > Do you use them in RAID One at all? > Yes, we have many pairs of SVP200 and SV300 SSDs in RAID1 (linux mdadm). One pair is ZFS RAID1. Why asking? Do you expect linux mdadm raid1 malfunction on SSDs? > > Do you have a favorite PCIe 16x carrier? > Socket M.2 M-key is PCIe x4 (or SATA). So this is 4x M.2 carrier? I got some free M.2 carriers (dual M.2, I think) with some ASUS motherboards. But I cannot use them, as we only have SATA SSDs due to excessive cost of PCIe SSDs. Our typical machine configuration is 120GB SSD for system partition, pair of 6 or 8TB HDDs for home and data storage (mdadm raid1). A nightly cron job to rsync backup the SSD contents.
