    • Good Value
Capacity: 1TB Style: 2280 M.2 SATA
I picked up this drive when it was $51. (It's a bit more at the moment.) For a Silicon Power 1TB M.2 drive I thought this was a pretty good deal, and a good value. I can't really give heat, speed, or longevity specs, because the system is a fanless, low wattage, media device that sits idles 99.9% of the time. I don't have a testing system with the tools necessary to do any real testing. The board didn't have a NVMe connector and so I used an ELUTENG M.2 to SATA Adapter (see here: https://amzn.to/49dZ851 this is my Amazon associates support link). The SATA III speed is fast enough for this system, and the adapter was $7 at the time, but please note that this adapter has a plastic housing and does not allow for heat dissipation. I can not recommend this SATA III adapter for drives that will be heavily used. ... show more
