Micron and Intel are finally breaking the fourth wall with their four bits per cell NAND memory SSD tech. These one terabit dies are made up utilising a 64-layer QLC design, which can fit far more data into its dense structure than TLC-based NAND drives, but has been tricky to implement so far.
The new chips from Intel-Micron show of ‘the world’s highest-density flash memory’, which is 33% denser than the TLC (3 bits per cell) structures found within many current SSD drives on the market. Supposedly, these are the first chips of this density to ever be commercially available, and Intel-Micron has already started to ship them out.
Don’t want to wait for QLC? Here are the best SSDs for gaming on the market today.
They’ll need a memory controller for that QLC memory, however, but luckily those have been in the works for some time. Earlier this year, Marvell created the 88SS1088 (catchy) which could deal with the latest QLC flash memory, among other third-party controllers. However, Intel have also been discussing how to get QLC functioning since they first utilised 64-layer memory last year - so it shouldn’t pose too much of an issue in getting this flash tech to market pretty swiftly.

As it stands, TLC memory is the cheapest to manufacturer for higher densities, but those extra bits come with their own set of drawbacks. TLC largely suffers from shorter lifespans compared to two-bit MLC and single-bit SLC structures. SLC, in particular, is favoured for reliability, although usually comes with a much higher cost for high capacity drives.
