The Seagate Exos Enterprise 20TB (part number ST20000NM002H) is a 3.5" hard drive with a Serial ATA III interface. It offers 20 TB of capacity, spins at 7200 RPM and has a 512 MB buffer. The interface transfer rate is 6 Gbit/s, with an average transfer rate of 285 MB/s, a sustained transfer rate of 272 MiB/s and an average latency of 4.16 ms.
For reliability, the drive is rated at 2,500,000 hours MTBF with an uncorrectable bit error rate of less than 1 per 10^15 bits read. It includes rotational vibration (RV) sensors and is rated for 40 G operating shock and 200 G non-operating shock. It runs on 5 / 12 V and draws 8.9 W during reads, 7.1 W during writes and 6.3 W at idle.
As a high-capacity enterprise SATA drive, it suits servers, storage arrays and other systems that hold large volumes of data.
