What the Seagate Exos X24 internal hard drive 20 TB 7200 RPM 512 MB 3.5" Serial ATA III is worth
The Seagate Exos X24 is an internal 3.5 inch hard drive with 20 To of capacity, spinning at 7200 rpm and using a Série ATA III interface at 6 Gbit/s. It includes a 512 Mo buffer and weighs 685 g.
Its measurements place the drive among those designed for intensive use: a mean time between failures of 2500000 hours, a non recoverable bit error rate below 1 per 10^15 bits read, and rotational vibration sensors to maintain performance in multi drive environments. Power draw stays moderate, from 6.3 W idle to 8.9 W during read operations.
Average transfer rate reaches 285 Mo/s, with an average latency of 4.16 ms, figures consistent with a drive built for large volume storage.
This drive suits PC setups requiring large storage capacity combined with measured long term reliability, typically servers, NAS units or storage oriented workstations.

Who this model suits
It’s for you if
Your first criterion is the capacity: it happens to be its best score.
You want a good score on the speed, above its category average.
You prefer a model tracked across several merchants, to buy at the right time.
Skip it if
Its lowest score is on the interface speed: skip it if that is decisive for you.
