Got bait-and-switched with Kingston NV2 2TB

[askopte]

Saw TPU's review with 1TB with some good numbers(5.5GB/s Read, 2.5GB/s write and 750mb/s when SLC cache is drained). Bought the 2TB version.

My one can only do 2GB/s R/W and when SLC cache is all used, all I end up is 200mb/s of write speed. In my opinion, very possibly an QLC drive.

Do not buy this product unless you are interested in gambling. Will try to return it but considering that package that force you to destoy it, don't think MemEx are going to accept it.

If anyone is interested in some shitty benchmark result for entertainment, just let me know.

that kinda goes for all Kingston products ¯\_(ツ)_/¯

its not going to "beat" my Kingston a400, with whooping 2.5mb read/write = )

See Kingston NV2 1 TB Specs | TechPowerUp SSD Database

and Kingston NV2 1 TB Specs | TechPowerUp SSD Database

There's two different controllers used, but performance shouldn't be very different due to them.

The advertised speeds are 3.5 GB/s read, and 2.1GB /s write ... also see the note at the bottom

NAND Die

Although this Die is a 4-plane design, most Kioxia BiCS5 NAND Dies used in most SSDs are dual planes design because of Yield and production cost.
And because of the die being dual-plane the Throughput is cut in half to 66 MB/s per die.
There is no CuA (Circuitry under Array) in the Dual-Plane variant.
Typical Endurance: 1700 P.E.C.
Rated Endurance: 5.000 (up to) P.E.C.

so if  the 2 TB model uses 4 dies, that could explain the maximum 4 x 66 MB = max 264 MB/s throughput

 

Maybe the reviewer got lucky or got a cherry picked SSD with dies that all have 4 planes and higher throughput.

It can come with QLC, yes. If you know the controller you can run a utility to identify the flash.
