Our Verdict

The CS2140 NVMe SSD performs like a mid-tier travel, but is out there for lowball price ranges. It’s a PCe 3/DRAM-significantly less (Host Buffer Memory) style and a serious discount, nevertheless we desire the organization would display screen TBW guarantee facts extra prominently.

NVMe SSD rates have been progressively dropping, but we have been still astonished to see the 1TB PNY CS2140 obtainable for less than $one hundred. Correct, it was only 5 pounds less than that, but which is continue to a good cost for a good accomplishing PCIe three SSD. It even sports a 5-year warranty, nevertheless that is offset to some degree by lower TBW rankings. All instructed, this drive is an excellent preference for any person hunting to snag a good each day SSD at a wonderful cost.

This review is section of our ongoing roundup of the ideal SSDs. Go there for information and facts on competing products and solutions and how we analyzed them.

Layout and features

The CS2140 is a PCIe three x4, M.two 2280, NVMe SSD using a Phison PS5019-E19-35 controller to move information in and out of unspecified NAND. We researched the numbers on the chips to no avail and PNY wasn’t forthcoming.

Thinking about the functionality, and that there were only two chips on a single facet of the PCB, with home for two far more, we’d guess a hundred thirty+ layer TLC. There is no DRAM cache, and PNY verified that the push is HMB (Host Memory Buffer), i.e. it takes advantage of some of your PC’s memory for most important cache. The general performance in our lengthy copies indicates that there is NAND as secondary cache becoming assigned dynamically.

Be aware that the Playstation 5, and some older Computer units do not guidance HBM. Slower performance may final result.

PNY states obviously that the generate carries a five-12 months guarantee, but does not make it simple to obtain the TBW (TeraBytes Created) score. It’s in a guarantee document that you can discover online at this url (scroll down to Warranties & Guidelines, broaden it, and open the PNY SSD Warranty Assertion.)

Hurdle prevail over, the TBW ratings for the numerous capacities of the CS2140 are: 250GB/150TBW, 500GB/200TBW, 1TB/400TBW, 2TB/1200TBW. Usually, they scale evenly and we can simply just say 150TBW per 250GB of ability or some these. These are odd to say the the very least.

Irrespective, looking at the pricing, they are realistic, if comparatively low—very low, in the 500GB and 1TB versions. Keep in brain that most people won’t generate even that a lot knowledge in five many years, and that reads are free. They set no don on the generate.

Why is the TBW rating vital?

The rationale we fuss is that SSD warranties are constrained by two components. 1 is the time interval, which is 5 many years in this circumstance. That’s great. The other is the amount of money of data which is been created to the push, which is typically calculated in terabytes, or yes, TBW.

For instance, if a travel is warrantied for five years but rated for 150TBW, and you’ve prepared a hundred seventy five terabytes, the warranty is void, even if it is been only a few a long time. PNY need to place this data exactly where it is less complicated to find.


The CS2140 is a very fantastic performer. It’s “only” PCIe 3, so you won’t get slicing edge quantities over PCIe 4, but just one of the strategies in the business is that find instances keep on being mostly the identical no matter of PCIe generation. Lightning quickly seek times generate at least half the NVMe encounter.

Regardless, we in contrast it to other drives utilizing DRAM-much less, host buffer memory drives running more than PCIe three.

The PNY CS2140 is a a lot quicker reader than its two HBM competition, but only the 2nd swiftest author.

The CS2140 was good, if not amazing in our 48GB transfers shown under.

The PNY CS2140 quickly bested the Atom fifty, but couldn’t match the SN770’s time which was mainly accrued by using great functionality with compact data files. Quite a few of the information in the several folders are duplicates.

Most load/save operations are very modest and in no way consider benefit of PCIe 4’s doubled throughput. Even packages that load/help save bigger (1GB to 10GB) chunks of facts enhance minimally with the newer PCIe bus.

Exactly where you will genuinely observe a variation is in pretty very long copies, these types of as our 450GB publish (revealed under) wherever the amplified bandwidth really has time to element in.

The PNY CS2140 was a little bit slower than the Adata Atom fifty, but not by much. The WD SN770 was relatively tragic in this specific exam.

All in all, regardless of the very low selling price, there is no real gotcha with the CS2140’s performance. Pleasant.

The PCIe 3 tests make the most of Windows 10 sixty four-bit operating on a Core i7-5820K/Asus X99 Deluxe system with four 16GB Kingston 2666MHz DDR4 modules, a Zotac (Nvidia) GT 710 1GB x2 PCIe graphics card, and an Asmedia ASM3242 USB three.2×2 card. It also is made up of a Gigabyte GC-Alpine Thunderbolt 3 card, and Softperfect Ramdisk three.4.six for the 48GB examine and generate tests.

Create functionality will minimize as the drive fills up. Also, in exceptional circumstances, components could adjust for the worse. PNY states it could improve NAND because of to a variety of factors but the drive will normally sustain the performance on the bundle and other advertising. Our standard ask for with all drives is that, if, specified very similar hardware, they do not perform as properly as our check device, make sure you permit us know.


Except if you regularly create really significant contiguous documents, the PNY CS2140 is a terrific offer and a very great every day performer. That PNY isn’t entirely forthright in exhibiting warranty data and ingredient specifications, however, limits our enthusiasm.
