For the 512GB Micron 4600 model, the manufacturer claims a sequential read speed of 10,300 MB/s and sequential write speed of 5,780 MB/s, random read performance of 800,000 IOPS and write performance of 1.2 million IOPS, and a resource of 300 TBW (terabytes of rewritten information).
The 1TB SSD will offer sequential read and write speeds of 14,500 and 11,500 MB/s, respectively, random read and write performance of 1.6 million and 2.1 million IOPS, and a resource of 600 TBW. For the 2TB and 4TB models, sequential read speeds of 14,500 MB/s and write speeds of 12,000 MB/s, random read and write performance of 2.1 million IOPS, and a resource of 1,200 and 1,600 TBW, respectively.
Micron is positioning the Micron 4600 PCIe Gen 5 NVMe drive series as solutions for notebook and PC OEMs. The new products offer a variety of security and encryption technologies, including TCG Opal, Security Protocol and Data Model (SPDM), Data Object Exchange (DOE), and Device Identifier Composition Engine (DICE).
The company also claims that the new SSDs deliver performance gains of up to 61% in media and entertainment applications, up to 59% in energy applications, up to 45% in product development applications, and up to 38% in life science applications, according to SPECwpc benchmarks, compared to PCIe 4.0 drives.
Micron’s 4600 PCIe Gen 5 SSDs are now shipping to PC and laptop manufacturers.
