KingSpec Chinese SSD Teardown

I became curious about Chinese SSDs.

Benchmark results

It's not a scam; it's showing good speed.

Upon disassembly, a chip named PF29F02T2AVCQK1 appeared.
It seems to be Intel's 144-layer QLC.

Around 2018, regarding these kinds of suspicious SSDs, it was hard to imagine them using major brand NAND. According to my research, Intel's SSD business was sold to SK Hynix and seems to have become a new company called Solidigm.

The current excessive SSD inventory might have been due to stock intended for disposing of NAND manufactured by the time of the business sale, which could have caused the price crash.

The 144-layer QLC itself from Intel/SK Hynix was released in April 2021, and considering that the acquisition was announced in October 2020, this might align.
It's likely that even B-grade NAND products, originally made for data centers and rejected for M.2 standards due to failing speed tests, would be perfectly fine with a SATA connection, and Chinese manufacturers might have procured them cheaply for this reason.
