Good drive. M.2 SATA, not NVME
Capacity: 1TB Style: 2280 M.2 SATA
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
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

.M2 Silicon Power storage failed with NAS cache' use
Capacity: 128GB Style: 2280 M.2 SATA
I have purchased Silicon Power 2.5" SSDs in the past. They are a cheap storage solution that allows me to compare different Linux distros - no issues of its failures. Comparable size storage from other brands are upto 20% more. That said, this particular storage, the M.2 SSD has been a failure. I purchased two of these to create an onboard read/write cache' as RAID 1 to complement the RAID 5 HDDs in my Synology 1517+ NAS device. Initially, the read/write cache' configured successfully. However, after 30 mins, the read/write cache became degraded, reverting to only read only. I spent close to four hours troubleshooting every possible option that included removing the storage, formatting it in linux and windows platforms, hoping to kickstart and make them usable. No luck. The part that bothered was that each time I started from scratch the issue would alternate. The NAS would point to one or the other as a failed resource. With frustrations and lost time, I have returned both and purchased a different brand (Transcend). It has been working - no issues after the initial setup. I do not recommend this product if anyone is planning to install them in a similar use case scenario as mine. Also, at this point, I will not be purchasing other Silicon Power products. The reliability is now in question. thanks for reading. ... show more
