Author: EIS Release Date: Apr 24, 2024

Micron is in mass production of a 232-layer QLC NAND which is  shipping in select Crucial SSDs, in volume production to enterprise storage customers and sampling to OEM PC manufacturers in the Micron 2500 NMVe SSD.

 

The NAND chip comes in capacities of  512GB, 1024GB and  2048GB. It has a  sequential 1MB readIMG_2917-150x150.png 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.
