Using SSD 960 PRO NVMe M.2 as cache/slog

[tbaror]

Hello All,

Anyone ever used SSD 960 PRO NVMe M.2 for cache L2ARC/ZILL drive, and if it would be a good choice?
Thanks

Fine for L2ARC.
Less sure about the SLOG (not ZILL, nor ZIL) part.
Does it have power loss protection? What's the durability?

Does it have power loss protection?

Nope. That immediately makes it a very poor choice for SLOG.

@tbaror, this device might be okay as an L2ARC, but it doesn't have the features you need for a SLOG device. In particular, it lacks power loss protection (as pointed out by @Ericloewe) and has a low durability rating as well.

For example, the Intel DC P3700 SSD has an endurance rating up to 62.05 PBW (Petabytes written) or up to 17 drive writes/day. The NVMe SSD 960 PRO is warrantied for 5 years or 400TBW (Terabytes written) for the 512GB model, 800TBW for the 1024GB model, and 1200TBW for the 2048GB model. In a nutshell, the Intel (which I highly recommend for a SLOG device) has better durability by two orders of magnitude.

Good luck!

Should make a great l2arc if with no PLP it's not a SLOG
