M.2 SSD’s are now pretty common and rely on either SATA or PCIe interface, but apparently there’s a new form factor with an M.4 SSD showcased at the recent Computex 2019 exhibition, and with Silicon Motion SM2270 controller leveraging a PCIe 3.0 x8 interface for up to 3,200 MB/s sustained sequential reads, 2,800 MB/s sustained sequential writes, as well as up to 800K/200K IOPS for respectively 4K read/write random operations.
Spotted by Anandtech at the event, Agylstor’s M.4 NVMe SSD come with the following specifications:
- Silicon Motion SM2270 controller with a three dual-core Arm Cortex-R5 processors with 2KB LDPC error correction and 16 NAND channels with 8 CE per channel (128 CE in total)
- Host Interface – PCIe Gen3 x8
- Command Protocol – NVMe 1.3
- Max Capacity – 16TB
Anandtech explains the M.4 SSD is essentially two M.2 SSDs glued together with (8) NAND packages on each side of the board. The company has now announced when we can expect the new drive to come to market, nor the target applications, but Agylstor’s website highlights the company provides storage solutions that aim at film & video production, energy monitoring, drones, and oil & gas exploration.
You’ll find a few more details about SM2270 controller in the product brief. It will probably take a while before we regularly start seeing M.4 sockets in single board computers or other embedded hardware platforms.
