### ⭐⭐⭐⭐⭐ Good drive. M.2 SATA, not NVME
*by N***. on February 12, 2026*

Keep in mind this it M.2 SATA, not NVME. Not all port and adapters support M.2 SATA. Did not work with my USB M.2 caddy, but worked great in an AM4 ASUS build!

### ⭐⭐⭐⭐⭐ Good Value
*by P***E on October 23, 2025*

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.
