Intel's 335 Series hasn't changed much since the preceding 330 Series — to the point that opening the drive up reveals the circuit board to be almost identical and still SandForce 2281-based. The secret is hidden in the serial numbers on the NAND itself, with Intel transitioning its memory from 25nm to a 20nm process.
Otherwise, things are, at least from a physical standpoint, exactly the same, with only firmware tweaks to provide a difference.
It's sold only as a 240GB capacity at this stage (with 224GB of that being usable), and in kit form — meaning you get a 2.5-inch to 3.5-inch bay adapter, a four pin to SATA power connector, a 6Gbps SATA cable, and a few screws along with the drive itself.
For benchmarking, both CrystalDiskMark and Anvil's Storage Utilities were set to 1GB datasets, using incompressible data.
