2TB NAS rated m2 SSD
Working great so far. Seems to be a genuine drive. There aren't a lot of options when it comes to NAS rated m2 SSD's, so I'm glad this is a good product. Don't forget to register your drive on the WD website for your warranty.

Versatile SSD for NAS
Had to replace a failed seagate rotational HDD in a 4 disk NAS but wanted to increase reliability after repeated disk failures. I was concerned that mixing the SSD replacement would be a problem with the RAID array. I needn’t have worried as the new drive was quickly installed, straight in to the disk carrier and quietly and quickly rebuilt the array - saving precious data in the process. It should massively improve durability of the array and remaining disks will be updated to these as they fail so the whole array will be more resilient.
