DapuStor unveils J5060 SSD splitting QLC flash into a fixed high-speed pSLC zone

DapuStor introduced a dual-mode firmware for its enterprise J5060 SSD that lets operators carve out a portion of QLC flash to run as pSLC, boosting speed at the cost of capacity. Depending on configuration, users sacrifice 6% to 20% of QLC storage in exchange for random-write performance that's over seven times faster, with the fixed region exposed as its own block device rather than a dynamic cache. The drive, shown at FMS 2026, spans 15.36TB to 122.88TB capacities but still has no announced price, customer, or release date.

1TB iPhone 18 Pro Max's QLC storage slows to 1.1 MB/s under heavy write loads

Testing by Bilibili channel Homolab found that the 1TB iPhone 18 Pro Max, which uses QLC NAND, suffers major performance drops compared to the 512GB TLC-based iPhone 18 Pro. Once its SLC and secondary TLC caches are exhausted, sustained writes fall to about 79.4 MB/s and can dip as low as 25.6 MB/s, worsening to just 1.1 MB/s once the drive is 60% full.
