There's another new SSD in town: Samsung's PM830. Although you won't find the drive lining store shelves or appearing in e-tail listings, Samsung has already begun shipping the thing to notebook and tablet makers for use in their systems. A standalone version targeted directly at end users is in the cards, but it's not available just yet.
So, what's the scoop? According to the official press release, the PM830 features a 6Gbps SATA controller and between 128 and 512GB of Toggle DDR NAND. Samsung doesn't reveal too much about the flash modules, which weigh in at 32Gb each and are built using a "20 nanometer class" fabrication process. Looks like these are the same ones the company put into mass production back in May.
Samsung has a history of developing its own SSD controllers, and the PM830 looks to be no different. It should be quite a bit faster than the 3Gbps 470 Series SSD (also known as the PM810 in OEM circles) that we reviewed last year. While the 470 Series is rated for 250MB/s sequential reads and 220MB/s writes, the PM830 is claimed to be capable of hitting 500MB/s and 350MB/s, respectively. Performance figures for random I/O aren't provided, but 256-bit AES encryption is supported by the new model.
The PM830's predecessor was a good all-around performer with one rather glaring exception: used-state copy performance. Let's hope Samsung has a better TRIM implementation this time around.
