Our Verdict
In the event you’re searching for glorious efficiency with out undue expenditure, then Kingston’s NV3 Gen 4 SSD is simply what the physician ordered.
Greatest Costs At the moment: Kingston NV3 NVMe SSD
$49.79
Final 12 months’s NV2 from Kingston delivered nice bang-for-your-SSD-buck. This 12 months’s NV3 continues to be splendidly reasonably priced, but massively improved — even setting a file writing our 450GB single file. Who would’ve thought?
What are the Kingston NV3’s options?
The NV3 is a PCIe 4.0 x4 (4 lane), M.2 NVMe SSD utilizing a DRAM-less (Host Reminiscence Buffer/HMB) design to chop down on prices. The controller is a Silicon Movement SM2268XG and the NAND is Kingston-labeled, stacked QLC. A minimum of that’s my assumption given the efficiency off cache and TBW score.
The precise sort of NAND and the variety of layers wasn’t specified by Kingston, and the corporate says that can differ from capability to capability.

How a lot does the Kingston NV3 value?
The NV3 is offered in 500GB/$54, 1TB/$77, 2TB/$154 (examined) flavors. A 4TB model is within the works, however not as of but priced.
Whereas the NV3 may be very cheap, it would simply value you some peace of thoughts. The drive is warrantied for under three years, fairly than the same old 5. Moreover, the TBW (terabytes that my be written) score is a miserly 160TBW per TB of NAND — nicely under the 250TBW per TB of NAND that was our earlier low.
That earlier low was for a QLC drive, therefore our hypothesis that that is what the NV3 employs. For no matter cause, vendor outlooks aren’t almost as sunny on the longevity of QLC as they’re on that of TLC. Nonetheless, 160TB is numerous writing for the common person.
How briskly is the Kingston NV3?
Whereas the artificial benchmark outcomes have been a contact under common for a HMB design, the NV3’s real-world outcomes have been barely higher. To not point out, an enormous enchancment over its NV2 predecessor.
The Essential P310 and Corsair M600 Elite proven within the charts are each equally performing 2TB PCIe 4.0 host reminiscence buffer designs, although the previous is a small form-factor 2230 (22mm broad, 30mm lengthy).
Whereas not rated the quickest of the three drives, the NV3’s CrystalDiskMark 8 sequential switch efficiency continues to be fairly good.
The NV3 additionally did amazingly nicely in random operations, although HMB SSDs aren’t on on par with DRAM designs on this regard.
Whereas the NV3 was quick in our 48GB transfers, it didn’t set any data.
The place the NV3 did set a file was in writing our 450GB file. Candy! Be aware that the NV2 was a 1TB SSD with significantly much less secondary cache, in addition to probably additionally using QLC, therefore the tragically lengthy write time.
As soon as the beneficiant secondary cache (roughly 600GB of the NAND written as SLC) on our 2TB check unit ran out throughout a subsequent 900GB file write, the NV3 additionally slowed dramatically — oscillating between 80MBps and 900MBps, totally on the low aspect.
Be aware that because the drive fills, this slowdown will happen earlier throughout writes. Nevertheless, when this occurred in our testing, the switch charge appeared to stabilize at round 220MBps fairly than oscillate.
This write slowdown will have an effect on only a few customers, however professionals consistently banging on their SSD may go for a extra constant TLC design, to not point out one with the next TBW score.
Do you have to purchase the Kingston NV3?
The NV3 offers you 98 % of the top-shelf NVMe expertise for an entire heck of rather a lot much less money. Until you actually intend to pound in your drive, it’s all most customers want. It is a unbelievable enchancment over the NV2 and an excellent worth.
