SanDisk Ultra Plus SSD review: Fast and inexpensive

A solid state drive meant specifically to replace aging hard drives.

When SanDisk announced the arrival of its Ultra Plus solid-state drive (SSD) at CES two weeks ago, the company made no bones about whom it was targeting: the consumer retrofit market. In other words, this SSD was made specifically to replace that old hard drive in your laptop or desktop.

Right off the bat I liked two things about this drive: It's extremely light (it only weighs 1.37 oz.) and it's cheap -- as in very inexpensive. The Ultra Plus comes in 64GB, 128GB and 256GB capacities. On SanDisk's site, they sell for $75, $110 and $210, respectively, but you can find them in retail outlets for even less. For example, the 256GB Ultra Plus -- which is the one I tested for this review -- can be had at for $170.

As I've said in past reviews, there is no single upgrade that will give you a bigger bang for the buck than an SSD, and it's all the better when it's an inexpensive one.

The Ultra Plus is a 2.5-in drive that uses multi-level cell (MLC) NAND flash and a SATA 3.0, 6Gbps drive interface. If you don't have the very latest laptop or desktop model, you are likely still using a SATA 2.0, 3Gbps drive interface, so the SSD won't perform quite as well for some applications. (The Apple MacBook Pro I tested the drive on has the latest SATA drive dock; more information about my test machine is in the next section.)

When SanDisk announced the Ultra Plus, the company also announced an upgrade to its NAND flash density: it went from 24-nanometer (nm) lithography to 19nm with the drive, which may account for the low price. The smaller the technology used for the semiconductor, the fewer chips are needed to build a drive.

The Ultra Plus sips power, using just 0.12 watts when active.
