A good SSD should have:
- power-loss protection (if it has one, the manufacturer will advertise it)
- high TBW/DWPD (part of every datasheet)
- quality NAND so SLC>eMLC>MLC>TLC>QLC (not all manufacturers will tell you this and often the same model is available with TLC and QLC NAND so you can't even trust reviews as the production might be changed from TLC to QLC later)
- big DRAM cache (usually manufacturers won't tell you the size)
- fast interface, so NVMe 4x PCIe 5.0>NVMe 4x PCIe 4.0>NVMe 4x PCIe 3.0>SAS>SATA/mSATA>USB)
Maybe other stuff like:
- proper documentation
- monitoring that not only updates offline
- encryption
- long warranty
- tools to configure and flash the SSD from linux or bootable device
- sufficient cooling (M.2 SSDs re terrible at that and might thermal throttle)
