While leading manufacturers of SSDs including portable ones, like Samsung, Western Digital, and WD-owned SanDisk, have all been offering TLC (triple-level cell) NAND flash memory for quite a while in the form of popular models like the T7, among others, Micron's Crucial has stuck to QLC (Quad-level cell) for its own offerings so far. These include popular yet affordable models like the X6 and the X8.
That is finally set to change as the company today announced the arrival of two new external SSDs in its family, namely the Crucial X9 Pro and the Crucial X10 Pro. The biggest difference between the new SKUs is the inclusion of TLC NAND this time. In case you are wondering, while QLC or four-bits-a-cell NAND is cheaper than TLC, the endurance can greatly suffer.
The new Pro X9 and X10 are more suitable for frequent usage compared to its previous QLC-based offerings. Crucial has shared the preliminary specifications of the two drives, though, detailed specs like the number of layers, and cache type, ie, whether DRAM or not, aren't available at the moment.
