Our take on the Seagate Exos 7E8 3.5 Inch Internal Hard Drive

The Seagate Exos 7E8 is a 4TB enterprise-class 3.5-inch hard drive spinning at 7200 rpm over SATA 6Gb/s, with a 256MB cache and a rated 2 million hours between failures. It is built for always-on workloads in servers, NAS boxes and workstations rather than for a typical desktop. Its sustained transfer rate of about 226 MB/s and 5.4W idle-to-10.9W active power draw put it in line with other 7200 rpm enterprise drives. Buyers choose it for the endurance rating and capacity per bay; it is louder and thirstier than a 5400 rpm desktop drive, and it is not a fast SSD replacement.

Questions and answers

Is this drive good for a home NAS?
Yes, if the NAS supports 3.5-inch SATA drives. Its 24/7 rating and 2 million hour MTBF suit always-on use, though it is louder than desktop drives.
How does it compare with a 5400 rpm desktop drive?
It spins faster and moves data quicker, but uses more power and makes more noise. A desktop drive is quieter for a single-bay PC.
Does it work in a standard desktop PC?
Yes. It uses a standard SATA 6Gb/s connector and 3.5-inch mounting, so any desktop with a free bay and SATA port can take it.
Is 256MB of cache enough?
For bulk storage, backups and media, yes. The cache mainly helps bursty sequential work; it does not make the drive feel like an SSD.
What is in the box?
The drive itself. SATA cables and mounting screws are usually not included, so check what your case or NAS provides.
Can I use it for surveillance recording?
It can handle continuous writes, but Seagate sells drives tuned for surveillance workloads. Check your recorder's approved drive list first.
Where is the Seagate Exos 7E8 3.5 Inch Internal Hard Drive cheapest?
At Newegg, for $249.99, as of our latest check.
