My WD SN580 vs TPU's sample

[Xuper]

I bought WD SN580 1TB , TPU Review

I Noticed Both Controller/Chip memory aren't the same with review sample. my Sample
Controller : SanDisk A101-000137
Chip : SanDisk 000888-1T00
Is it safe? My NVMe is older than TPU's sample?

CrystalDiskMark's Test :

Compare to TPU's test , RND4K is 3x slower. is it due to FCLK Ryzen ? ( Ryzen 5900X on X370 Prime pro , PCIe 3.0 4X )

I gather it would be faster in a Gen 4 slot.

Its perfectly fine. Even Kitguru has a review with the Sandisk 000888 1T00 as the controller

Sometimes manufacturers run out of certain chips and they have to source from elsewhere or use a different chip. WD owns Sandisk so everything is fine

@GabrielLP14 Maybe a new variant?

RND4K? Maybe, but I kinda doubt it.

Ya, you're probably right.

A dig up read.

970 evo plus 1tb RND4K performance

Hello i ve just got a 970 evo plus 1 tb for my pc and used crystaldiskmark for the performances. But my RND4K performance shows low i think. When i looked on net i saw 1871 / 2050 on RND4K where mine is only 663/578. I wud be happy if u tell me what cause this plz, thanks.

Yes
Judging by the NAND Flash code which is
"3191YCAVC018" we can see that it uses the same BiCS5 TLC which I think is still 512Gb

The controller on the other hand is not the same Polaris MP16+ we find on TPU review.

Instead it appears to be another completely different controller. I'll let you guys know what I find about it

Actually guys apparently is a much similar controller the "A101-000137"
SanDisk Polaris Mp16+ ARM 32-bit Cortex-R - TSMC 16nm FinFET 4-Channels (16 CE in total) at 1600 MTps

All of these following controllers look identical

20-82-10081-A1

20-82-10082-A1

A101-000137

A101-000138

Same Hardware Configuration

TPU's sample

For the record, I bought mine in retail on Jun 29 2023 from the WD Store

You're most likely held back by the motherboard, as the M.2 slot is only PCIe 3.0, not PCIe 4.0.

Different test settings. Wiz is testing at Q32T16:

And you're testing at Q32T1:

Some of your other test parameters are different also.

I did bench again and Close to TPU , Thanks to all who helped me.
