### ⭐⭐⭐⭐⭐ Works great.
*by N***I on August 29, 2026*

### ⭐⭐⭐⭐⭐ A great standard

### ⭐⭐⭐⭐⭐ Feeling blue is not always a bad thing. Enjoy these drives!
*by B***L on August 22, 2025*

Got a pair of these as parity disks for an Unraid NAS set up. Yes they are “blue”. Yes they are “desktop”. Yes, they are 5400RPM, but they are also CMR! So far they have been reliable - no errors upon delivery. Chew up relatively less power. Even if they last only half as long as I expect (I have working drives from the early oughts!), the price/value ratio is worth it compared to “NAS”-specific Red/Black drives.
