Seagate Exos X20 Spec and Price in Brazil

SATA20TB7200 RPM

Exos X20 is Seagate's 18-20TB enterprise nearline generation: helium-sealed 7200rpm mechanics, 256MB of cache, a 550TB/year workload rating, and a five-year warranty, per the Seagate data sheet. Sustained throughput reaches 285 MB/s — the top of the SATA hard-drive envelope — and the CMR recording keeps it safe for every RAID level. On SATA it is a dense, dependable data-center capacity tier, and the price per terabyte is the argument for it.
