SATA SSD's are in a weird space. HDD are cheaper and more reliable for large storage pools. NVME is everywhere and provides those quick speeds and are even faster if you need that. There just aren't many use cases where SATA SSD's are the best option.

SATA SSDs have one advantage though - their size. You don't see m.2 form factor SSDs going well over 8TBs, but for a larger SATA drive you can find >8TBs easily. Samsung had the best offering for this recently - Samsung SSD 870 QVO The enterprise world has U2, but us plebs don't really have a comparable alternative.

  No advantage over SAS here - it's the same form factor.

    Problem here is I haven't seen SAS connectors in any consumer motherboard.

      Yeah, you need an adapter. Search on eBay for "freeNAS" and "LSI" and you'll find a bunch listed for way under $100.

SATA SSD has a huge heatsink attached to it. It is crucial for 24/7 use. NVME needs active cooling to survive.

  Lots of consumer SATA SSDs don't have any thermal pads between the PCB and the case, and plastic cases are common. Heat just isn't a problem for a drive that's only drawing 2-3W under load. And most consumer NVMe SSDs don't need any extra cooling for normal use cases, because consumer workloads only generate bursts of high-speed IO and don't sustain high power draw long enough for cooling to be a serious concern. In the datacenter space where it is actually reasonable to expect drives to be busy around the clock, nobody's been trying to get away with passive cooling even for SATA SSDs.

  Are any SATA SSDs actually built to sink heat into the enclosure? e.g. The 860 Pro released in 2018 has a PCB taking up a third of plastic enclosure with no heatsinks to speak of: https://www.myfixguide.com/samsung-860-pro-ssd-teardown/ https://www.myfixguide.com/samsung-860-pro-ssd-teardown/ And even in worst-case hammering of drives, thermally throttled NVMEs can still sustain higher speeds than SATA drives.

    It isn't plastic, though, it's aluminum.
