Your QNAP TBS-464-8G supports PCIe Gen 3 x2 interfaces, but it's important to note that it is backward compatible. This means you can use SSDs designed for PCIe Gen 3 x4 interfaces without any issues, although they will operate at Gen 3 x2 speeds. So, the lanes don't necessarily need to match.
When selecting NVMe SSDs for caching, reliability is crucial, especially considering the high read and write operations involved. It's essential to look at metrics like DWPD (Drive Writes Per Day) and MTBF (Mean Time Between Failures).
Here are a few NVMe SSD options with their respective DWPD ratings:
Samsung 970 Pro: 0.66 DWPD
Seagate FireCuda 510: 0.7 DWPD
Seagate FireCuda 520: 0.9 DWPD
Seagate IronWolf 525: 0.7 DWPD
Seagate Firecuda 530: 0.7 DWPD
Synology SNV3400: 0.68 DWPD
WD Red SN700: 1.0 DWPD
Choosing SSDs with DWPD ratings of 0.5 and above ensures durability and longevity, making them suitable for caching purposes. You can refer to this list for more details: NVMe M.2 List with Endurance (DWPD/MTBF).
