Product Information

The IronWolf Pro 20TB offers some good incentives to choose it over the 18TB version and smaller capacities in each series that go beyond just being bigger. Should the drive fail after exceeding these workload limits, Seagate can reject warranty replacement accordingly. The complete reading of the drive for an integrity test once a week would use up 1,040TB per year, nearly twice the yearly limit, and that’s without any operational use.

This hard drive offers flexible connectivity with ports available for FireWire 800, USB 3.0, and eSATA. This unit offers two FireWire 800 ports for flexibility through Daisy Chain. It is compatible with Windows and Mac and comes with a 2-year warranty. It is rumoured that by the end of the year, Toshiba will reveal a 10-platter 26TB drive based on microwave-assisted switching (MAS-MAMR) technology, to be then followed by an 11-platter 30TB model next year.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. As hard drive capacity increases, but speeds stay the same, duplicating a single hard drive will become an ever longer lasting process. You could duplicate two 10 TB simultaneously in half the time it takes to do the same with a 20 TB drive. One commenter makes the analogy to a city’s water supply: Picture a city with a massive tower, but only garden hose to get it out. The argument for the use of 20 TB drives The UltraStar DC HC560 is the only direct competitor for the EXOS 20TB, as Toshiba hasn’t released a 20TB drive yet.

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.

Many years of close collaboration work with our key component suppliers is leading to impactful technology breakthroughs to achieve higher capacities, which ultimately reduces total cost of ownership (TCO) of our nearline HDDs.” Max Payne 1 & 2 Remake in the “production readiness stage” while fans will have to wait longer for Control 2

This hard drive comes in a sleek white and silver plastic box that matches nicely with most desk decors. The aesthetics of this drive are impressive. You can choose the device with one or two drives bays for hard disks, and if you choose the bigger two-bay option, you will need to look at the overall dimensions of the product. On paper, 20 TB sound like a fantastic innovation. Using just 20 TB drives, you could have 100 TB of available storage space with just six drives in your Unraid server. But Linus, from the Linus Tech Tips YouTube channel, has a compelling argument against increasing the size of hard drives from where they currently are.

While buying an external hard drive for your needs, you need to ensure that you are getting a device that helps to store your data safely. The most important thing to consider is its reliability, as you don’t like to buy an external hard drive which fails on you and causes you to lose all your important data. 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.
