Solid-state drives are popular among enthusiasts and are available in many laptops and ready-made computers, but most users to store large amounts of data continue to be content with hard disks. Samsung is working on eliminating the need for HDD using NAND memory based on QLC.

This type of flash memory is slower compared to the popular TLC NAND in SSDs, but has a higher storage density. One chip can accommodate up to 1.5 TB of data. If the composition of the drive includes 32 chips, its volume in this case will reach 48 Tb, and for corporate drives Samsung will offer a capacity of up to 128TB.

The latter will not be available for purchase in stores, but 48 TB is two orders of magnitude more than the modern SSDs offer. Naturally, they will be very expensive, but there is a possibility that the price of drives with a capacity of several terabytes will come close to hard disks.

The volume is not the only value-relevant drive, do not forget about the durability. It's QLC lower compared to TLC NAND, but storing 4 bits in a cell is an attempt to increase it.

Together with the existing technologies for equalizing wear and correcting errors, the duration of the work will continue to exceed the average user's need.

Although the maximum speed of QLC is not impressive, parallel access to data in similar RAID configurations will speed up operations with files.

Also in the coming months should be updated drives Samsung 960 NVMe. It's unlikely that QLC NAND will appear in them, but it's impossible to exclude it yet..
