Scality plans to introduce Nearline Solid State Drives (NL-SSDs) as a complement in the storage tiers for hot and warm data, and has already tested prototypes of NL-SSDs from Solidigm and Samsung. Samsung positions NL-SSDs as a replacement for mechanical hard drives, adopting the EDSFF E3.L/E2 form factor, with single-drive capacities starting at 250TB and reaching up to 1PB. In a 4RU space, the total capacity can approach 50PB, while a single rack can reach nearly 0.5EB. NL-SSDs are based on a NAND flash technology different from traditional QLC, with a write endurance of 0.1 full drive writes per day (0.1 WPD), lower than QLC's 0.5 WPD, but with no significant difference in performance compared to QLC.
