WD 20TB Elements Desktop External Hard Drive - USB 3.0, Black

Product Information

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. LaCie is a company popular for it’s Thunderbolt storage. No other company has offered as many different models with this technology. The LaCie 5Big comes with a traditional pedestal form factor that can fit nicely under a desk. This hard drive uses Marvell hardware RAID technology, and you can align the disks in RAID 0, 1, 5, 6, 10 arrays or go for a simple JBOD configuration. Moreover, users can also configure more than one array in the system. While I dont disagree in principle with your take on >18TB HDDs, its worthwhile to point out that even if a drive fails, your data is still accessible. The point of the parity drives isnt just to allow you to rebuild the array, but also to maintain persistent access to them in the event of a failure. Additionally, accessing your media is no more likely to cause an additional failure during reconstruction than it is during a scrub. 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. 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.

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. CrystalDiskMark: 289.07MBps (read); 295.75MBps (write) Atto: 281.32MBps (read, 256MB);275.27MBps (write, 256MB) 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.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 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.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. The UltraStar DC HC560 is the only direct competitor for the EXOS 20TB, as Toshiba hasn’t released a 20TB drive yet.

Evidently, both Seagate and Western Digital did the calculations and came to the same conclusion about these devices and how much use they are likely to handle before they need replacing. But, based purely on the relatively low 300TB/y workload, we’d consider other options that aren’t specifically for the commercial and enterprise NAS sectors. When we first saw these numbers, they sounded reasonable because the workload value isn’t like a TBW number on an SSD, as the 300TB is for each year of operation up to five years.In terms of operational speed, we found it difficult to separate the IronWolf Pro and EXOS 20TB in our benchmarking. Most of the damage to the NAND cells occurs during random writes in an SSD, and relatively minor wear happens when reading. The transfer time of this drive depends on your home network setup. The speed isn’t as fast as an external drive connected to a computer, but you get an added benefit to access your files from any device on your network. Seagate has tuned the EXOS for data centre use, where high-capacity RAID arrays are used for big data applications, distributed file systems and disaster recovery platforms.

Versatile Capabilities: Intelligently adapts to the scale of your AI environment, supporting up to 64 HD video streams and 32 AI streams. 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.The latest Windows 11 update won't install for some users, and tanks gaming performance even if it does To pave the way for even more capacious drives, Toshiba intends to shift towards heat assisted magnetic recording (HAMR) technology. The company says it plans to offer its first 35TB HDD, based on HAMR, before 2026. One surprise was that considering the performance improvements, we had expected the 20TB drive to pull more power and generate more heat.
