Review on 💾 High-Performance 4TB Datacenter HDD - WD SE 7200 RPM 6 Gb/s SATA with 64MB Cache - WD4000F9YZ by Jeffrey Nunes

Bought a few of these drives for my QNAP NAS. The performance is excellent and they are not too loud. Revain packaged them well and I haven't had any issues with damage from rough handling during shipping. These drives were shipped overseas, so I'm even more impressed. Note that when mounting these drives using the 6-32 threaded holes on the bottom of the device, be aware that they are smaller than other drives. The 3/16" pan head screws that came with my NAS were TOO LONG to securely mount the drive. The screws jammed, leaving about 1/32 inch unthreaded. I had to file the screws to make them fit all the way. You might want to make sure you have 6-32 short screws.
