[SOLVED] is Phison PS3113-S13T controller only for QLC NAND?

[Pextaxmx]

I was curious about the Inland Professional 256 Gb SATA SSD, which is advertised as a TLC drive. (https://www.microcenter.com/product...6-gbps-25-inch-7mm-internal-solid-state-drive)

Then I found that someone opened up this drive and found PS3113-S13T controller.
Searching for the controller, it appears to be a QLC specific controller?
There is no DRAM on the board either.

NAND markings are:
TA59G63AWV
K2119N
AB5075A12

Is it really a DRAMless QLC drive??

My bad... there were many articles about how this controller is a solution for QLD NAND chips.
Then there is Phison reference spec sheet that specifies 3D TLC NAND.

The Inland drive above must be DRAMless, TLC drive.

Anandtech is reporting that this controller has been validated for QLC NAND.

"To date, Phison has validated three of its controllers for use with 3D QLC NAND flash memory: two SATA controllers and one PCIe controller. The PS3111-S11T and PS3113-S13T are aimed at entry-level SATA SSDs, whereas the PS5013-E13T is designed for inexpensive PCIe 3.0 x4 NVMe drives. "

TP5NE76AWV --> BiCS4 QLC NAND
NA5BG66AOA --> N18 QLC NAND

Note that Anandtech's Phison reference PCB designs are marked with "A117013VF0000E1A" for the BiCS4 PCB and "A117011NP004402N-V3" for the N18 PCB. In fact your PCB appears to be the same reference design as the BiCS4 version.

This review (of a different SSD) refers to "Toshiba TABBG65AWV BiCS4 3D TLC NAND":

https://news.xfastest.com/review/review-06/90235/t-force-cardea-iops-ssd-xf-review/

Therefore your NAND part number is looking more like BiCS4 3D TLC.

This review ...

https://www.tweaktown.com/articles/...iew-toshiba-bics-tlc-micron-3d-mlc/index.html

... states that TA79G51ARA is "Toshiba's BiCS Gen 2 3D TLC (3-bit per cell) flash".
