Using `hdparm` to benchmark, I recorded read speeds exceeding 185 MB/sec when connected directly via SATA. That's faster than Western Digital's claimed speed and almost double what I get from older drives. Transfers and backups take half the time!

hdparm -t --direct /dev/sda
/dev/sda:
Timing O_DIRECT disk reads: 558 MB in 3.01 seconds = 185.50 MB/sec

In addition to the great performance, this drive runs cool and quiet in my NAS enclosure thanks to the 5400RPM rotational speed. And it's designed for 24/7 operation, giving me confidence in its longevity and reliability under constant use.
With 8TB capacity, I've got plenty of headroom for backups, media storage, and archiving important files while still leaving space to grow. And the CMR technology means maximum compatibility with my NAS RAID.
For home and small office NAS setups that demand a perfect blend of high capacity, sustained performance, cool operation and proven reliability, the WD Red Plus line is a winner.
This drive meets my needs perfectly!
