If you can afford it though, get one of our best PS5 SSDs . Just bear in mind that the maximum capacity is 4TB, not 18 and that it will cost you more, much more. High capacity 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. Triple-Level Cell (TLC): TLC stores 3-bits per cell for up to eight levels of charge. Commonly used for consumer grade products, TLC has a lower performance, reliability and endurance to the previous two. However a cheaper price and higher memory density make up for the drop in performance. The 3D variant can reach up to 3K P/E cycles. It's easy to assume that SSDs and hard drives are simple products when compared to laptops, TVs, or PCs, but there's still plenty to consider if you want to buy new storage.
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. 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 MarketsBoth the Western Digital G-Drive 18TB and LaCie d2 Professional 18TB are perfect for storing massive quantities of data whilst offering very fast data access. They both feature 7200 RPM drives for fast data transfers. The LaCie includes a Thunderbolt 3 interface where the Western Digital only USB 3.0. You need to move up to the Western Digital G-Drive Pro 18TB to get the faster Thunderbolt 3 interface. They feature aluminium cases for improved heat distribution. Hard drives can get quite hot under continuous load, therefore having adequate ventilation will help extend the longevity of the drive. 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. Operational Data - represents data that is used to support your daily workflows, such as documents, images or videos. For such a large drive this would typically be needed for larger files such as with video or virtual machine files. Single-Level Cell (SLC): They can only store one bit per cell and take up to two levels of charge. SLC NAND offers the highest performance, reliability and endurance (up to 100K P/E (program/erase) cycles). However, the memory density is the lowest among the variants and the price per GB is considerably higher than the other types. SLC is only available in 2D format and mostly used in enterprise setups. The EXOS drive beats the IronWolf Pro with a workload limit of 550TB, a significant improvement over the 300TB of its brother mechanism. These are the same workload limits as the Western Digital UltraStar DC HC560 20TB and WD Gold 20TB.
The matrix below shows the current pricing for each available capacity point in all the considered hard drive families. HDD Pricing Matrix (as of November 4, 2022) Business buyers should buy an SSD or a hard drive that has a higher endurance rating. That's because productivity PCs and laptops tend to read and write files to storage at a greater frequency than the storage in consumer systems. That's true for internal and external hardware in equal measure. 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. If you want to have a PCIe drive instead, expect to pay a significant premium although the difference in speed will be one magnitude higher thanks to the use of PCIe Gen 4 protocol. Other 8TB SSDs include
TOPICS
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? 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 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. 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.
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. 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. 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.

Another Seagate drive with ten 2TB platters in the classic 3.5-inch form factor to sit alongside the new IronWolf Pro 20TB. The only significant difference on the outside is that the EXOS comes in a SAS flavor in addition to a conventional SATA variety model. 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.
