Product Information

We also test power consumption and temperature. Power consumption will vary with drive performance, RPM, and more, and it’s important to look at four different cases: maximum power draw, average power draw, idle power draw, and workload efficiency. Power usage can add up with multiple drives. Temperature is also an important metric for hard drives, as overheating is a common cause of failure, particularly during sustained workloads. In considering the non-enterprise drives, we note that the 'Unrecoverable Read Errors' metric is 10x worse for the WD and Toshiba drives compared to the Seagate ones. The MTTF metric for the IronWolf Pro is slightly better than the other drives (at 1.2M vs. 1M hours).

Those that work at home, like many people these days, want files they’ve modified to be secured the moment that they’ve closed them, not an hour later. As that increases the probability that data won’t be secured before something unfortunate happens. 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? 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.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. Western Digital is one of the most trusted names in data storage, and trust is vital for a device that will hold so much of your valuable memories, media, and information. WD’s My Book external hard drive comes in an 8TB size and includes all the reliability, performance, and convenience you could want in a personal storage solution.

There are a few differences between a hard drive and an SSD, but it’s important to first note that they pretty much have the same job, they just function differently. It is important to be aware of the drive’s form factor, with 3.5” being the most common for the best HDDs (this is the only type we cover). If you need 2.5”, your options are more limited, especially for capacity. Otherwise, your computer case’s ability to house a certain number of 3.5” drives might be your primary limitation. For performance, HDDs are also often gauged by rotations per minute (RPM), which is usually a direct indicator of performance. The RPM value impacts sequential transfers as well as random access latency. Lower RPM drives tend to be quieter and more efficient, while higher RPM drives have better performance. There are also variable RPM drives that try to achieve the best of both worlds. Power draw, heat, and noise are factors related to performance.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 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 Price-wise, you’ll typically find that hard drives are less expensive than SSDs and offer quite a bit more storage capacity for a lower price. However, SSDs tend to be a lot faster than even the best hard drives because they don’t have to rely on moving parts like HDDs. The best SSDs can function up to 10 times faster than traditional hard drives. 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 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.
