It works differently than standard external hard drives, and you can plug it straight into the router to get a direct internet connection. You can share files to and from your devices via Wi-Fi, and it also means that you can get your data at any time from anywhere, and you don’t need to leave a specific computer on to access your data. The UltraStar DC HC560 is the only direct competitor for the EXOS 20TB, as Toshiba hasn’t released a 20TB drive yet. This Is a 3.5 drive, so be sure that it will fit your console or whatever you are placing it in. It's important that people know this is not a standard drive and is made for surveillance cameras, or something that is access to an overridden on a regular basis. Unlike a standard hard drive in your PC that has correction control most of these drives for the surveillance systems do not have correction. Meaning once it copies the data there is no verification that the data was copied correctly. Why this is not usually a problem on a system is a good hard drive and a smooth running operating system it could result in data loss. That is why it is advised to buy a surveillance hard drive, something that is specifically made to run off and and to keep copying the files without correction.

Alongside its IronWolf Pro, Seagate also makes a 20TB EXOS design that we’ll be covering shortly, aimed at the same slice of the Enterprise market that the UltraStar DC HC560 was created. It comes with 256MB of cache, a five-year warranty and three years of Rescue Data Recovery Services. MTBF (Mean Time Between Failure) is 1.2 million hours, and the yearly workload is 300TB.Seagate brought its 20TB products to market alongside Western Digital, eliminating any special bragging rights on this scale of drive.

One surprise was that considering the performance improvements, we had expected the 20TB drive to pull more power and generate more heat. It comes in a trayless design that offers a simple way of HDD installation. Just pull out the lever to insert or withdraw the HDDs. Once you set up the device, you can easily switch between RAID modes, connect the cable, and turn on the power to enjoy the massive capability and outstanding performance of the Mobius. In terms of operational speed, we found it difficult to separate the IronWolf Pro and EXOS 20TB in our benchmarking. Connecting external drives to this unit and managing different settings on this drive is very easy, and you won’t face any issues while setting it up or operating. This drive is available in a different storage configuration, and it is available in 4 TB, 6 TB, 8 TB, 12 TB, 16 TB, and 20 TB storage capacities. The SATA EXOS comes either with Standard or SED FastFormat, and the SAS model adds SED-FIPS to those options.

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. 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.”

The Mobius 5-Bay FireWire 800 is offered by Oyen Digital. It is a powerful RAID storage management device that offers flexible connectivity and easy HDD access. It comes with flexible RAID storage management options such as RAID 0, RAID 1, RAID 3, RAID 10, RAID 5, and JBOD combined. 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. In a physical hard drive, as the EXOS is, wear happens whenever the platters are rotating, irrespective of the reading or writing that accompanies that movement.

The veracity of massive capacity

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. 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. That’s a worse workload than the cheapest unbranded SSD available. But it is even less impressive when you realise that Seagate defines the workload as “Annualized Workload Rate = (Lifetime Writes + Lifetime Reads) * (8760 / Lifetime Power On Hours)” What we see here is the reality of technology with moving parts, where each operation the drive performs contributes to its ultimate failure, much like the playing of a vinyl record.

But, the WD Red Pro 20TB that’s in direct competition with the Seagate IronWolf Pro 20TB is much cheaper, at least at the MSRP level. 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.

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. That’s still not amazing compared with an unbranded NAND SSD, though it’s much better than the 75TB of workload transfer that the IronWolf Pro offers. 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.
