Seagate launched another 22TB hard disk drive for the enterprise market. The IronWolf Pro (ST22000NT001) has 10 platters and uses CMR (conventional magnetic recording) rather than the controversial SMR to reach that capacity. It has a 256MB cache and a 7200RPM rotational speed, which means that it is likely to be one of the fastest HDD around.
What’s perhaps more important to our readers though is that it is optimized for NAS (network attached storage) devices with a five year warranty, a 550TB/year workload rating, a bunch of proprietary features and a mean time before failure of 2.5M hours. Seagate’s marketing literature mentions “AgileArray with dual-plane balancing, time-limited error recovery (TLER), and rotational vibration (RV) sensors to deliver top RAID performance in multi-bay environments”
