There was no CM8, and the CM7, which was introduced almost three years ago, follows directly behind its successor as the CM9. The PCIE 5.0 SSD for data centers uses the new BICS8 generation TLC NAND for storage capacities up to 61.44 TB. 14.8 GB/s and 3.4 million IOPS should be possible when reading.
BICS8 TLC for More Capacity and Performance
The new presentation is the new BICS8 Flash, which is being used for the first time on a Kioxia enterprise SSD as a TLC version. In terms of energy efficiency, performance, and density, the memory should offer “significant advances” while doubling the “available storage capacity per flash memory module,” the company advertises, comparing it to its predecessor, which is still equipped with BICS5.
Writes approximately twice as fast as its predecessor
We’re talking about performance increases of up to 65% for random writes, 55% for random reads, and 95% for sequential writes. MB/S Pro Watt efficiency is expected to increase by 55% and by 75% for sequential writes. As is often the case, it’s unclear which model is being compared to its predecessor.
Specifically, Kioxie mentions maximum throughput rates of 14.8 GB/s for reading and 11 GB/s for writing. The focus on data reading becomes clear with 3.4 million IOPS when reading the no-choice elections and only 800,000 IOPS in the no-election letter.
The Kioxia CM9 is expected to be offered in 2.5-inch form factors (up to 61.44 TB) and E3.s (up to 30.72 TB). There’s also talk of dual-port support and variants with 1 DWPD (Drive Write Per Day) or 3 DWPD.
The CM9 is now being sampled and will reportedly be seen at Dell Technologies World, taking place in Las Vegas from May 19th to 22nd.
