Micron in mass production of 232-layer QLC NAND

Update: April 17, 2024 Tags:250ecoeliclt

The NAND chip comes in capacities of  512GB, 1024GB and  2048GB. It has a  sequential 1MB read up to 7100 MB/s, a sequential 1MB write up to 6000 MB/s, a random 4KB read up to 1000 KIOPS and a random 4KB write up to 1000 KIOPS. Latency is read (TYP): 50μs, writev (TYP): 12μs. MTTF is  2 million device hours.

The Micron 2500 SSD claims to be the first QLC SSD that approaches PCIe Gen 4 theoretical saturation performance, boasting up to 7.1 GB/s sequential read speeds. It outperforms TLC-based NAND and QLC-based NAND SSDs in the value segment, with superior performance to competitor offerings: 4

Micron 2500 SSD performance
Performance Metric Versus TLC Client SSDs Versus QLC Client SSDs
Sequential read Up to 48% better Up to 72% better
Sequential write Up to 32% better Up to 97% better
Random read Up to 38% better Up to 131% better
Random write Up to 25% better Up to 85% better

The Micron 2500 SSD is available in 22 x 30mm, 22 x 42mm and 22 x 80mm form factors, in 512GB up to 2TB capacities. It has a compact 2TB 22 x 30mm option suitable for handheld gaming devices.

The single-sided design of these SSDs provides greater flexibility for OEMs to integrate into systems that range from ultra-thin devices to workstations.
