If you are looking to buy a new SSD, you may want to wait just a few more days until the Micron M600 drives hit the store shelves. These are based on a new 16nm process and offer great features and performance that includes Dynamic Write Acceleration. These new drives will come in 2.5-inch, mSATA and M.2 platforms. It will be interesting to see how this write acceleration performs in the real world. In theory, it looks impressive.
According to Micron, accelerating writes in this fashion can lead to dramatic improvements in total power consumption because, while the drive consumes slightly more power in some cases, it still slashes the amount of time required to perform the write. There are a few caveats with Dynamic Write Acceleration. It cannot accelerate sustained random write workloads indefinitely -- eventually the drive will begin performing garbage collection, and write acceleration doesn't function when it's taking out the trash.
