The Samsung 840 Pro was our top SSD until the OCZ Vector came along several months later and was able to run neck-and-neck with the Sammy through our benchmark gauntlet. As it currently stands, the 256GB versions of these drives both wear a 9/Kick Ass bandolier around their midsections, but there’s still another contest that has yet to be decided. So this month, we gathered the 512GB versions of both drives and set them loose in the blood-splattered arena known as the Lab.

Remember Samsung's 470 SSD series? That marked Samsung's first foray into the retail SSD market, and we rated the 256GB version a solid 8 for its competitive performance. Representing another first for Samsung, meet the PM830, the only SATA 6Gbps SSD in Samsung's stable and offered in up to 512GB of capacity.
Samsung sounds awfully excited about its latest SSD, a 512GB drive utilzing "toggle-mode DDR NAND" memory. It's the first SSD to do so, and according to Samsung, this is a pretty major deal. As Samsung explains it, toggle-mode DDR allows for higher performance without a subsequent increase in power consumption.
"The resulting power throttling capability enables the drive’s high-performance levels without any increase in power consumption over a 40nm-class 16Gb NAND-based 256GB SSD," Samsung said. "The controller also analyzes frequency of use and preferences of the user to automatically activate a low-power mode that can extend a notebook’s battery life for an hour or more."
Samsung's first-run SSD to employ this technology checks in with up to 250MB/s sequential read and up to 220MB/s sequential write speeds. Respectable, though not earth shattering when considering that the competition has begun cranking out high-performance SSDs with read and write speeds in the vicinity of 280MB/s.
Volume production is expected to begin next month. No price has yet been set.
A-DATA this week launced its 512GB XPG 2.5-inch solid state drive (SSD), which it claims is the highest capacity SSD to date. The new drive will be pitched to both laptop and desktop users.
Balancing capacity with performance, A-DATA says its 512GB XPG reads data at up to 230MB/s and writes up to 160MB/s. By comparison, Intel's highly touted X-25M boasts read and write speeds of up to 250MB/s and 70MB/s, respectively, giving A-DATA's a sizable paper-spec advantage in write speeds and a slight disadvantage in read bandwidth.
The new drive comes enclosed in a "dashing, durable, lightweight aluminum casing" and boasts a shock resistance rating of 1500G/0.5ms. In other words, it could probably survive an accidental drop or three, even if the rest of your laptop doesn't.
