Though Micron While not being the first to announce mass manufacturing of 232-layer 3D NAND chips, it’s the first to announce a collection of solid-state drives (SSDs) utilizing this kind of reminiscence. is the 2550 collectionwhich additionally demonstrates the benefit of this kind of chip that condenses way more info per chip, since the collection is obtainable in M.2 2230, 2242 and 2280 codecs in capacities of 256 GB, 512 GB and 1 TB.
These M.2 2230 and 2242 codecs, extra typical of laptops and mini-PCs, will achieve relevance as NAND chips can include extra info. I miss that there have been increased capability choices, 2 TB for instance for the M.2 2242 mannequin, however every little thing will come. This collection has a PCIe 4.0 ×4 interface with an NVMe 1.4 protocol, and implements bodily encryption with AES-256.
|Micron 2550 Series|
|Characteristic||2550, 256GB||2550, 512GB||2550, 1TB|
|Random Read 4 KB||380000 IOPS||500000 IOPS||550000 IOPS|
|Random Write 4KB||400000 IOPS||600000 IOPS||600000 IOPS|
Drives obtain as much as 5000/4000 MB/s sequential learn/write and 550/600 kIOPS random learn/write. The sturdiness ranges from 150 TB to 600 TB, and the consumption in operation is beneath 5.5 watts. The firm doesn’t give particulars of the controller built-in into these models, however ensures that it’s manufactured in an “advanced node”. It is a non-buffered DRAM collection utilizing a reminiscence buffer in the host, so that’s what limits the most efficiency however contributes to creating it a extra economical collection.
