WD 18TB Elements Desktop External Hard Drive - USB 3.0, Black

Product Information

Since your computers work on the binary system, there is an increment of 2 to the 10th power or 1,024 in each storage level. Therefore, in the computer system:

If you want to buy a hard drive for a specialist business PC or the best gaming SSD for your PC or console, there are some additional considerations. 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.

Maak een einde aan de kosten en complexiteit van het opslaan, verplaatsen en activeren van gegevens op schaal. The drive is made up of nine 2TB platters (with 18 heads) offering the highest areal density across the industry, 256MB cache and has a spindle speed of up to 7200RPM. There’s a dual-attached motor and RV sensors to guarantee steady performance, which means 1.2 million hours MTBF.

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 The Exos X20 does not have the three-year recovery plan that other Seagate drives on this list have, which further hints that it's a better choice for data and cloud centers. This doesn’t preclude its use in NAS systems or for other applications, but it won’t be as cost-effective in those scenarios. You can also consider a drive that supports RAID (Redundant Array of Inexpensive Disks) that can offer data redundancy by writing data to multiple hard drives in parallel. This is referred to a RAID Level 1, and is supported on popular models such as the Western Digital G-RAID 2 or LaCie 2big RAID 16TB drives. Note that due to the drives being mirrored the available disk capacity will be half that of the total, so a 24TB drive will be 12TB, 16TB will be 8TB, etc. Note : While this is a WD drive, this is not affected by the wiping bug that's affecting some WD and SanDisk external SSDs. 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.Hard disk drives still make up the most of the storage market both in the enterprise and in the consumer markets in terms of capacity. However, they’re stalling with CMR reaching a plateau and SMR, proving to be a poisoned chalice and not a technology that will get NAS owners enthused. 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. 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. Find out more about how we test. One feature that I like about the WD My Book Desktop external hard drives is that they have built-in support for 256-bit AES hardware encryption, which means that you can encrypt your data without relying on some third-party software -- it's all handled on the drive. And for those seeking recommendations, we've curated a list of the best NAS hard drives suitable for personal, home office, and small business use, utilize our custom price comparison tools to ensure you're obtaining value for money.

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 is certainly a massive amount of data. Whilst some will easily be able to consume it all, many will never be able to need such large data storage. Therefore I recommend you look at your specific needs before choosing a hard drive capacity. Simply choosing the largest capacity drive you can find may not make the most sense. Having multiple copies of data for additional redundancy, it may be safer to have 2 (or more) smaller drives with the same copy of data, therefore reducing the event of data loss if a drive were to fail. For power efficiency, the drive is designed to go to sleep after about ten minutes of inactivity. For most home users, this is a perfect setting, but it can be customized or disabled using the WD Drive Utilities software. I've had mine set to not go to sleep since day one, and it has no problem with this. 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 MarketsIn 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 Consumer Hard Drives: November 2022 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 Even if you invest in the best NAS device, an inferior drive could mean not only a poor return on investment but also potential data loss. When looking for the best hard drive for your NAS, consider your priorities. Is top-tier speed paramount, or is storage capacity at the forefront of your needs? Features like enhanced cache and vibration protection might also play a role in your decision. 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.
