Seagate has demonstrated a prototype NVMe SSD with a capacity of 64TB and a maximum throughput of 13 GB/s. The drive consists of eight M.2 SSDs in RAID, on a single PCIe card, and multiple high performance controllers.
Samples of products that use the same technology are expected for the second half of 2018. Today’s demonstrated SSD is part of Seagate’s high-performance Nytro series and the SSD uses technology that’s also used in the last year introduced Nytro XP 7200 SSDs. These drives are single PCIe x16 cards with four M.2. connectors and they are able to achieve throughputs of 10 GB/s and capacities of up to 7.7 TB.
Today’s prototype is able to achieve a maximum throughput of 13GB/s and will become available in capacities up to 64TB. Because Seagate reports the 64TB drive is made up of 8 M.2 SSDs, it appears the company has 8TB M.2. in the works.
Update: TheRegister reports that Seagate has told them they are indeed 8TB modules. They are using early 512Gbit/die 3D TLC samples from Micron.
