10 Best 4TB SSDs: M.2 NVMe, SATA, and External Drives

With SSDs being the ideal storage choice for consumer devices like laptops, desktops, and consoles, manufacturers are increasingly pushing the technology to higher capacities. If low storage capacity was a cause for avoiding SSDs in the past, now’s the time to reconsider as larger capacity SSDs are becoming more prevalent. More specifically, 4TB SSDs are finally going mainstream, driving manufacturers to cut prices significantly. Therefore, we have carefully crated this list of the best 4TB SDDs.

You can thank TLC or Triple Level Cell flash NAND for high storage SSDs. Compared to older SLC and MLC SSDs, manufacturers can pack more storage in the same form factor and keep costs low. QLC or quad-level cell technology SSDs are also being introduced, though we would recommend them for 8TB SSDs as they are slower and depend highly on their SLC cache, which fills up fast on lower capacity SSDs.

With so many 4TB SSD options available in the market, it’s tough to determine which one is best for you. We did the research and developed this comprehensive list of 4TB SSDs to help you make the right choice as these SSDs cost a lot.

Best 4TB M.2 NVMe SSDs

1Sabrent 4TB Rocket

Capacity:256GB, 512GB, 1TB, 2TB, 4TB | Controller: Phison PS5012-E12S | Memory: Kioxia BiCS3 96L 3D TLC | Interface: M.2 PCIe 3.0 x4 | Sequential read: 3,450MB/s (4TB version) | Sequential write: 3,000MB/s (4TB version)
Key features:
  • Fast TLC flash NAND with DDR4 cache
  • Sabrent Acronis True Image software included for free
  • 5-year warranty (1 year without registration)

Sabrent’s Rocket SSD manages to pack quite a lot of storage in the M.2 2280 form factor. The SSD employs TLC flash to store a large amount of data in such limited space. The SSD’s read and write performance is rated at 3,450 and 3,000 MB/s, with a real-world performance expected to be around the average for NVMe SSDs, a testament to the TLC flash NAND used.

Apart from the drive itself, Sabrent offers several features like a free version of the Acronis True Image software, a five-year warranty, and even a free aluminum case if you need to store your SSD externally. You also get a five-year warranty, provided you register the device on Sabrent’s website within 90 days of purchase.

The Rocket utilizes the Phison E12S controller, which is smaller than the traditional E12, letting the SSD use the extra space for the additional flash modules. Kioxia manufactures the TLC flash used in the Sabrent Rocket SSD. With an increase of newer high capacity SSDs like Sabrent’s own Rocket Q launching with QLC, it’s not long before drives like this become scarce.

With a rough estimate of a 3000 TBW capacity, the Sabrent Rocket 4TB SSD should last you a fair bit of time. While SLC and MLC are way better in endurance, we hardly find any of them in the 4TB capacity anyway, so this is the best you can get. With a price tag of $699.99, the SSD is pretty expensive but is way more valuable if the applications you work with can use high speeds.

If you’re looking to show off your blazing fast NVMe SSD in your PC build, then the XPG S40G from ADATA is the best choice for you. Sporting RGB LEDs on either side, the S40G also syncs with your motherboard to be compatible with your existing RGB software. The 4TB capacity is the XPG S40G’s latest release, and it performs well with a top read and write speed of 3500 MB/s and 3000 MB/s, respectively.

The SSD’s RGB takes up a bit more space than a typical M.2 SSD, making it the ideal choice for PC motherboards as laptops have very tight space constraints and will cover up the RGB. The Realtek RTS5762 controller is not what you would find on standard 4TB NVMe SSDs, but it nevertheless performs on par with the other NVMe SSDs available in the market.

The SSD also employs a Micron TLC flash memory, which is again much faster and longer-lasting than the QLC NVMe drives sold today.

The S40G does have some quirks, though. Its RGB software is pretty buggy and makes the RGB on the SSD almost unusable. Add to this the inadequate cooling due to the LEDs’ plastic being thermally insulating, forcing the drive to shut down after some time.

For a price tag of $599.99, the ADATA XPG S40G is the cheapest 4TB NVMe SSD with a TLC flash NAND for sale on the market. Its limited support for laptops, buggy software, and insufficient cooling keep it from being the best, and we would recommend spending extra if your data is mission-critical.

4WD Black 4TB AN1500

Specifications:
Capacity:1TB, 2TB, 4TB | Controller: Marvell 88NR2241 | Memory: WD 96L 3D TLC | Interface: PCIe 3.0 x8 | Sequential read: 6,500MB/s (4TB version) | Sequential write: 4,100MB/s (4TB version)

  • RAID0 PCIe Gen3 x8 configuration for faster speeds
  • WD Black Dashboard software included
  • 13 LED RGB lighting

The WD Black AN1500 is different from the typical 4TB NVMe SSD you would usually find in the market. While some manufacturers use the M.2 interface to transfer data at high speeds, WD instead opts for the PCIe 3.0 x8 slot via an add-in card. To fully utilize the PCIe 3.0 x8 slot, the AN1500 employs two 2TB NVMe SSDs in the RAID0 configuration. This configuration allows the SSD to reach a write speed of 4,100 MB/s and a read speed of 6500 MB/s.

The AN 1500 features an enterprise-level RAID controller and two WD Black SN750 NVMe SSDs. A plug and play RAID0 configuration such as this makes it extremely easy to achieve high speeds without the need to source SSDs and a custom PCIe add-in card with a RAID controller separately.

It still utilizes TLC SSDs, so the endurance and speeds will not be as good as you would get with an SLC or MLC SSD. WD’s five-year warranty is also a great addition as the endurance of a RAID0 configuration like this is not easy to calculate. The AN1500 also comes with RGB LEDs to spruce up your PC’s lighting and should seamlessly sync with existing control software.

For $999, the add-in card is the most expensive 4TB SSD you can currently buy. Newer PCIe Gen4 SSDs matching the AN1500 in speed are a better option to consider once they and the motherboards and CPUs that support them go mainstream. However, most people with existing hardware can consider the WD Black AN1500 is the fastest you can go with a 4TB SSD right now.

NVMe VS. SATA:

Most SSDs in the market today come with either one of two interfaces, NVMe or SATA. NVMe is a relatively new interface that employs PCIe to transfer data from the host’s storage device at much higher speeds. SATA, on the other hand, being initially developed for hard drives, is much slower and can only output a maximum transfer rate of 6Gbps.

NVMe speeds are instead capped on the number of PCIe lanes, with a typical PCIe 3.0 x4 connection having a speed of 16Gbps. This speed variation gives rise to the differences in NVMe and SATA SSDs. All NVMe SSDs come with either the M.2 or PCIe connectors. Today, most SATA SSDs are still available in the 2.5-inch form factor, but some employ the M.2 interface but are slower than M.2 NVMes.

At their core, all SSDs utilize the same technology for storage. To accommodate larger capacities while maintaining the same form factor, most manufacturers use Triple Level Cell flash, more commonly known as TLC flash NAND. This flash structure stores three bits per cell compared to the two and one bits per cell of MLC and SLC cache, respectively. TLC does come with its shortcomings, though. It has a much lower write speed and endurance than MLC and SLC.

Final Thoughts

In the end, the 4TB SSD you choose is solely dependent on how much speed, endurance, and portability you need. While 4TB SSDs do not have a significant price difference between SATA and NVMe, choosing the right one for your needs will ultimately lead you to save quite a bit of money. So, go through and decide the best one from our handy list. We hope that you found this article helpful and informative.
