Solidigm will release a 61TB SSD next year

Solidigm, a division of SK hynix inherited from Intel, will release solid-state drives up to 61TB. The manufacturer announced this when presenting its new roadmap at Tech Field Day 2022, writes the Blocks & Files portal. We are talking about server drives that will be available in U.2 (2.5 inch), E1.S, E1.L and E3.S formats and are expected to be available from the first half of 2023.

The company will release the Essential Endurance and Value Endurance series of SSDs based on the fourth generation of 192-layer 3D NAND QLC memory (4 bits per cell). The Essential Endurance series uses 8 KB blocks. It includes SSD models with volumes of 3.84, 7.68, 15.36 and 30.72 TB with a declared resource for rewriting information up to 32 PB. The Value Endurance Series models use 16KB blocks and are available in 7.68TB, 15.36TB, 30.72TB, and 61.44TB. The maximum overwrite capacity for these SSDs is around 65PB.

According to Solidigm, about 80% of the SSDs on the market use 3D NAND TLC memory (3 bits per cell). The manufacturer assumes that in the future these solutions will be replaced by models based on QLC flash memory. For example, the manufacturer is positioning the same series of Essential Endurance drives as a replacement for models based on 3D NAND-TLC memory with lower performance in 4K random writes. And Value Endurance Series drives become a more affordable alternative to TLC models that are better suited for frequent reading. They are less optimized for small, mixed-cycle read/write workloads.

It is noteworthy that some of the future Solidigm SSDs will have a capacity higher than that of the most advanced hard drive models. For example, the same Western Digital offers a hard drive with a capacity of only up to 26 TB for the corporate sector and up to 22 TB for the consumer sector. The declared resource of 65PB of overwritten information for SSDs that Solidigm speaks of means that they can overwrite 35.6TB of information every day for five years. Solidigm notes that the vast majority of enterprise-grade QLC-based drives on the market barely produce just 15% of their total declared write resources.

The random write performance of future Solidigm drives will reach 113,000 IOPS and throughput of 474 MB/s. According to the company, its SSDs will be up to six times faster than competitors based on 3D NAND QLC flash and almost a quarter faster than competing solutions based on 3D NAND TLC flash. The write delay indicator for new products is 0.563 ms. This is up to 84% lower than competitors with QLC memory and 20% lower than models with TLC memory.
