During our roam of Storage Visions we noticed a bit of a trend. Of the limited devices on display, an increasing number of them were of the M.2 form factor. Our first sighting of an M.2 device was last CES, at a Micron press briefing. Since then, we have only seen a few announcements of support for this form factor. The key to M.2 is that host will be able to support both SATA and PCIe connectivity through the same physical port. While many of the SSDs available will start off using well-known SATA controllers, M.2 will make the transition to PCIe storage controllers significantly easier.
Here are some of the M.2 devices we spotted. First a couple from SanDisk:
M.2 makes things a bit simpler as far as PCB size goes. Where mSATA had a bunch of random names denoting various sized, M.2 simply puts the dimensions (in mm) right after the name. For example, M.2 2260 is 22mm wide band 60mm in length. Below are some more examples from various vendors:
Above we see samples from Toshiba (upper left), Kingston (center left), and Intel (two right). We also spoted an engineering sample of an M.2 Intel 1500 Pro:
The part number of this unit is CVDA321500BX180H, and like other 1500 Pro models it is equipped with a newer low-power SandForce 2281.
Here's hoping these devices trickle out into the mainstream. Standardization should help with adoption and upgradeability, especially in Ultrabooks and smaller devices incorporating these units.
