About this deal

This hard drive has very similar specifications and pricing as the Seagate IronWolf Pro, which has the advantage of a slightly higher maximum sustained write speed and Seagate’s three-year rescue plan. The Red Pro has a larger DRAM cache, though, and its OptiNAND technology gave better 4KB results, so its better for workloads that have small I/O. Synology has introduced 8, 12, and 16TB enterprise hard drives (rebranded Toshiba Enterprise HDDs with custom firmware), but they are meant specifically for Synology NAS units (no warranties if used in other systems) and are not part of this buyer's guide. Toshiba's MG09 18TB HDDs based on FC-MAMR are quite new in the market, and will be added in a future update to this buyer's guide It’s a little unfortunate that the Seagate IronWolf NAS drives come at a premium, but they aren’t priced much more expensively than a standard hard drive at their capacity. However, their native NAS optimization makes that premium totally worth it. The most common use for hard drives, though, is simple file transfers. Our DiskBench test estimates transfer performance with a real-world workload that is useful for calculating how long a transfer could take. Hard drives have consistent performance and will hit their maximum sustained speed at QD1 with large enough I/O, which is illustrated in our ATTO benchmark results. This is particularly useful for showing differences in technology and capacity as drives get bigger and faster. The IronWolf Pro has larger caches for many of its models with the same storage capacity, including 20TB, and also a corresponding workload rating increase, from 300 to 550 TB/year.

Traditional hard drives have a circular disk (platter) that stores your data - as the disk spins, the read-write arm reads data on the disc or writes data to it as it spins. Solid state drives (SSDs) have no moving parts, instead using NAND (Negative-AND) flash memory - the more memory chips an SSD has, the more storage capacity.

It must also be kept in mind that the Segate Exos Enterprise and WD Gold are enterprise drives meant to be used in server rooms where noise and power consumption (to a large extent) are not as important as performance. As per the Exos 16TB and 18TB Exos Enterprise product manuals, the acoustics specifications are around 28-30 dB at idle, and 32-34 dB for performance seeks. Power consumption ranges from 1.31W at standby to 9.45W for high queue-depth random writes, with idling average being around 5.26W. The numbers for WD Gold are very similar. On the other hand, a drive like WD Red Pro has idle acoustics around 20 dB for the high-capacity models, though performance seeks are around 36 dB. Unless one is buying for a datacenter storage array, it is fair to expect that the drives are going to be idle for more time than doing performance seeks in SMB or SOHO NAS units. While WD doesn't break down power consumption by access trace type, the specifications indicate power numbers between 0.6W and 6.2W - considerably lower than the Exos / Gold. Price can be a key factor (which is the reason for shifting a number of our recommendations to the Exos series), but data hoarders with multi-bay NAS units or those in a SOHO setting may prefer thte NAS to be not as noisy or consume more power than needed. That’s about a half of what you might expect from a SATA SSD externally connected via USB 3.0, and about a fifth of the best NVMe SSD external drives connected via USB 3.2 Gen 2 ports. There are two important issues here that need to be confronted, in our opinion, those of redundancy and securing live data. Based on these metrics, it is clear that the enterprise drives (Seagate Exos Enterprise and WD Gold) are rated to be more reliable in the long run over a big sample set. However, most consumer use-cases do not need a 550 TB/yr workload rating. 180 - 300 TB/yr workload rating is plenty reasonable for most users when the drives are going to be used as part of RAID arrays.

There are three active vendors in the consumer hard drive space - Seagate, Toshiba, and Western Digital. Their retail offerings currently top out at 20TB, 18TB, and 22TB respectively. Western Digital is about as established an HDD brand as it gets, and even today, it is putting out incredibly solid hard drives for long term storage at great prices. Nowhere is this more the case than with its line of WD Blue hard drives.Mainstream hard drives of 8TB capacity generally can’t fit into a portable size, but the WD My Book is still a reasonably compact unit that houses a 3.5-inch hard disk drive (HDD). It stands upright and measures 6.7 inches tall, 1.9 inches wide, and 5.5 inches deep. You must plug it into the wall with a power adapter, so it’s not easy to tote around different places. After filtering out models that don't apply to your use-case (as an example, for usage in a 4-bay NAS enclosure, one could rule out the Toshiba X300 straight away), we can then take a look at how the specifications of various drive families compare. Hard Drive Families - Metrics of Interest What’s great about the My Book is that it is remarkably easy to configure and use, being the definition of a plug-in-and-go scenario. One of the aspects not mentioned in the above table is that the WD Red SMR drive is in the 5400 RPM class, while the other drives (including the Red Plus) are all 7200 RPM. Despite similar spindle speeds, the Red Plus firmware is optimized for a low noise profile across most capacity points. It might not win out on benchmarks, but possesses qualities that are important for some consumer use-cases. Another aspect to be kept in mind is that the WD Red line is now exclusively SMR-based, with the CMR drives moving to the WD Red Plus line. Unless the consumer is technically savvy enough to understand the pitfalls of SMR and its applicability to the desired use-case, the SMR-based WD Red line is best avoided. Hence, we do not include the WD Red lineup in our recommendatios. Pricing Matrix and Concluding Remarks Seagate’s Exos X20 drive is very similar to its IronWolf Pro line. Its higher workload rate and MTBF specification suggest it is more for enterprise use, however. It doesn’t reach 22TB like the WD Gold, and also has less cache. That aside, the performance and warranty are both good, so this is a choice that comes down to pricing.

Game consoles hard drives fill up fast with massive libraries. And, like laptops, the upgrade path for 2.5-inch hard drives isn’t all that great, but that’s where an external drive comes in.Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you.

As we’ve already mentioned the review drive is sold as 8TB, and without dismantling it, we’ve assumed that the drive inside is a WD RED mechanism of the same capacity. So how do you know which hard drive is best for you? There are a lot of things to consider, so it's not as simple as just buying the "best" hard drive. Which hard drive is best? If you're looking for a large amount of storage, faster transfer speeds, and are okay with a large form factor and higher cost, an external drive is the best option. In our series of Hard Disk Drive guides, here’s the latest update to our list of recommended HDDs. All numbers in the text are updated to reflect pricing at the time of writing.

Best of all, because this is an external hard drive, you can take all your favorite games on the go. Or, if you're working on a major project that requires a certain degree of portability, the Western Digital My Book is also a great work storage device in a pinch thanks to its large capacity. How to choose the best hard drive for you One of the easiest ways to narrow down the search for a suitable hard drive is to look at the target market of each family. The table below lists the suggested target market for each hard drive family we are considering today. Hard Drive Families - Target Markets But curiously, another choice comes from another line at Western Digital, the Elements Desktop Drive. It’s priced slightly lower, has less attractive styling, and doesn’t come with the software that the My Book line includes. It might not be anything groundbreaking, but if you need to dump 8TB, or more, of data from your computer and have it still accessible, the Western Digital My Book does this job admirably.
