Specifications, Pricing and Availability


When we wrote the preview article two weeks ago, the A110 wasn't on SanDisk's website. We took the image above from the new web page and we now have all of the specifications. The A110 comes in two capacity sizes, 128GB and 256GB. Both are M.2 2260 form factor.

SanDisk claims up to 740 MB/s sequential read performance and 625 MB/s sequential write performance. The 4K read IOPS rating is 115K and 73K for 4K writes. Getting this level of performance doesn't come easy, though. The motherboard and Windows both have PCIe power savings features that you need to turn off to reach maximum performance. Even then, reaching maximum performance is difficult without additional tweaks. We ran the A110 on a few different boards and couldn't hit some of the specifications SanDisk claims. We learned quite a bit, and we'll go over a lot of details on the last page of this review.

At the time of writing, I wasn't able to find the A110 available anywhere. Haswell based ultrabooks and notebooks are rare right now. Later in the year we'll see a massive push in the ultrabook space with high resolution displays, amazing battery life and M.2 based SSDs.

The new M.2 based SSDs play a large role in the amazing battery life. SanDisk claims just 80mW in slumber mode (256GB model). Early next month we'll publish an article on new power states in Haswell based systems and talk about how SSDs like the A110 can operate on the same amount of power you generate just by walking across the floor.
