Product Information

Maak een einde aan de kosten en complexiteit van het opslaan, verplaatsen en activeren van gegevens op schaal. 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 Consumer Hard Drives: November 2022

Multi-Level Cell (MLC): MLC takes up to 2-bits per cell and four levels of charge. Available both in 2D and 3D variants, MLC offers good performance, reliability and endurance at a cheaper price than SLC. 3D NAND variants can reach P/E cycles in the range of 30K. Hard disk drives are cheap and offer plenty of capacity but they are bound to disappear in a not-so-distant future. Right now, the biggest portable hard disk drive has a capacity of 5TB; it uses a special drive that is slightly bigger than a standard laptop HDD which has a width of 2.5-inch and a height of 7mm. How about a portable external hard drive? Compact and handy, it's ideal for long journeys or holidays. Simply pop them in the bag and carry it wherever you go, it will make sure your memories are stored and protected so that you can cherish them later. If you need to store data on your computer, then our desktop external hard drive is an ideal choice. Our collection offers storage up to 8 TB. Save files in a single location or you can even free the space on the internal drive of your computer for better performance. From SSD hard drives to HDD hard drives, we have a lot in our collection. Not sure which one to get? Browse our hard drive guide and get all the information you need with your tech queries. 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.

18TB WD My Book Desktop external hard drive

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. 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 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. 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). On the plus side of this equation, the new IronWolf Pro 20TB is 2TB bigger than the 18TB model, about 25MB/s faster at reading and writing, and it's more power-efficient. All these advantages come at a price that is only marginally more than the 18TB option. So it's a no-brainer forcommercial and enterprise NASto support the needs of creative professionals and large businesses, indeed?

Now you might be wondering why the advertised HDD storage does not match the usable data capacity. Most hard drive or SSD users have the same question- why actual drive capacity is lower than the space mentioned on the label? But before you blame the drive manufacturer for giving false information, it’s important to know the reason behind this capacity discrepancy. So, let’s find out how the capacity of hard disk drives is calculated and why their actual size differs from the advertised size. 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. 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.

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 The Seagate Skyhawk AI HDD is designed with “AI'' firmware to improve the drive’s ability to handle recording, video analysis, and GPU analytics workloads. This includes up to 64 HD video streams and 32 AI streams with zero dropped frames. This is combined with a robust warranty, including a high workload rate and Seagate’s three-year data recovery service.

If this product is unavailable in your region, you may need to use a specialist parcel forwarding service to take advantage of the deal. 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.The latest Windows 11 update won't install for some users, and tanks gaming performance even if it does

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.In terms of recent product introductions, the retail availability of Western Digital's OptiNAND-equipped 22TB drives has improved. Pricing for Toshiba's 18TB drives using FC-MAMR, as well as Seagate's Exos 20TB and IronWolf Pro 20TB have shown a downward trend. With the HDD supply chain having pretty much recovered, and the short-lived Chia craze a thing of the past, prices have largely stabilized. Many high-capacity models such as the Seagate IronWolf Pro line are currently running 15-20% lower than launch MSRPs, and the Exos lineup continues to offer great capacity for money. The IronWolf NAS models deliver slightly better performance compared to the WD Red / WD Red Plus, but, have correspondingly higher power consumption numbers. On the SMB / SME NAS front, the WD Red Pro has started reaching better price points compared to previous quarters, managing to undercut the IronWolf Pro across almost all capacities. However, a plus point for the IronWolf Pro is the inclusion of the Data Rescue Service for a 3-year period in addition to the usual warranty.
