Should the drive fail after exceeding these workload limits, Seagate can reject warranty replacement accordingly. The previous 18TB IronWolf Pro could read and write sequentially at about 260MB/s, and the 20TB achieved more than 285MB/s in most tests. That’s nearly a 10% improvement, almost the same margin as the increase in capacity. I would never use 20 TB drives to store my photography, videography, or any work-related files for the reasons listed above. If one of those hard drives was to fail, and I had all my work on it, I would have to wait two days or more, just to be able to find out if everything still was there. Were there two 10 TB hard drives instead of a single 20 TB hard drive and one of them would die, there would be a 50% chance that the file I was looking was still accessible. And if it wasn’t, rebuilding the dead hard drive would only take a day.

Doing the same calculations that we did for the IronWolf Pro, taking the 2750TB limit over five years and dividing that by the capacity, we end up with total bytes transferred of 137.5 TB per TB of drive capacity. Toshiba continues to work closely with the cloud companies to understand their capacity and performance requirements, and the ability to utilize our next-generation technologies will be key to meeting our customers’ needs,” said Ragfhu Gururangan, VP Engineering and Product Marketing at Toshiba America. Oddly, while idle, the 20TB pulls a little more power than the 18TB, 5.5W from 5.2W, but critically when it is running, it uses less power. Down from 8W on the 18TB to 7.7W on the 20TB, its standby power level is also less. Another advantage that you can get from this drive is it’s USB 3.1 2 nd Gen interface. You can expect faster data transfers due to its x2 Thunderbolt 3 ports. Moreover, it also comes with an HDMI port to offer 4K and HDR video streaming. You can easily store large files like 4K videos at a lightning-fast speed.Where the IronWolf Pro 20TB offered an MTBF (Mean Time Between Failure) is 1.2 million hours, and the yearly workload is 300TB. The EXOS 20TB exceeds those levels with a 2.5-million-hour MTBF rating and 550TB annual workload.

The SATA EXOS comes either with Standard or SED FastFormat, and the SAS model adds SED-FIPS to those options. Why in the UK the HC560 is cheaper than the WD Gold is curious, and the Red Pro is the most expensive in the UK of all drives. But unlike the IronWolf Pro, the 20TB design shows no improvements in operational power demands over the 18TB models, and the SAS models use an extra 0.4W over the SATA versions at idle. If you set the drive on RAID 1 or mirror mode, your computer will deal with it as a single drive with half the storage. You will also face slower performance because your computer will only write to one drive. This attracts creative professionals like musicians or videographers who capture moments regularly that can never be recreated. The third mode is JBOD. You can choose this one, and your PC will see the 2Big as two individual drives.The maximum power the EXOS can consume 9.4W on SATA and 9.8W on SAS, but the typical demands are 6.4W and 6.8W, less than the average 7.7W that the IronWolf requires.
