Solidigm is produced with a 61 TB SSD

The company would base its new developments on a QLC 3D NAND flash design with 192 cell layers.

A solid a Technology Field Day 2022 presented a roadmap to the event, which revealed a lot about their upcoming developments targeting the large business sector. The company is planning two product ranges for the 192-cell QLC NAND flash chip, namely an Essential Endurance line and a Value Endurance line. The former would use 4, while the latter would use at least 16 kB of alignment.


One of the fundamental problems here is QLC-type nand flash memory which stores four bits per cell, which has a bad reputation in terms of the number of programming (write / erase) cycles. At the same time, according to Solidigm, this doesn’t really matter much in practice, because the top of the Value Endurance series is designed for a load capacity of around 65 PBW, which means 35.6 TB of data can be written per day. after five years. This is a high enough number that QLC shouldn’t be a problem, and according to the company, only 15% of the officially specified load capacity is used for most SSDs entering data centers.


Solidigm plans the Essential Endurance series for capacities of 3.84, 7.68, 15.36 and 30.72 TB with the E1.S, E3.S and U.2 formats, while Value Endurance will arrive at 7.68 TB and that would take that to 61.44 TB. The latter will also have E3.S and U.2 formats, but E1.St will be replaced by E1.L.

The biggest benefit of the company’s upcoming developments is that they can offer up to four times more capacity within a U2 high server than data center SSDs running on traditional TLC NAND flash chips, which may be a consideration. meaningful to potential customers. The release is scheduled for the first half of next year.
