Samsung volition offer iv versions of the 830 Serial that range in capacity and include 64GB, 128GB, 256GB and 512GB models. All four feature the aforementioned 520MB/s read performance, but writing speed goes down as you compress the drive'due south capacity. The larger 512GB and 256GB versions claim write throughput of 400MB/s, the 128GB version is slower at 320MB/south, and the 64GB model spec indicates just 160MB/south, making it one-half as fast every bit the 128GB version.

The new 830 Series SSDs receive a new Samsung S4LJ204X01-Y040 controller. This purportedly three-core ARM-based controller supports the SATA 6Gb/s interface and tin also exist paired with the latest 20nm NAND wink retentivity.

The 470 Series featured a pair of 128MB Samsung DDR2-667 enshroud chips for total enshroud capacity of 256MB. The 830 Series is as well equipped with a 256MB cache just using a single fleck, Samsung has used their own DDR2-800 (K4T2G314QF-MCF7) memory.

Our 512GB review unit carried Samsung NAND flash memory labeled K9UHGY8U7A-HCK0. This memory is made using 20nm tech, in total at that place are 8 chips with each IC having a massive 64GB density. The drive uses a thin 7mm chassis that will fit virtually modern ultraportables that require it.

Samsung claims a MTBF of i.five million hours and 1500G shock resistance. This is a typical guess that most manufacturers label their SSDs with.

Like all SSDs the 830 Series is meant to be very power conservative. At idle all four models use 0.078 watts and a mere 0.127 watts when agile according to spec. The active ability rating is amazing as compared to almost other SSDs that use between two and four watts of power. however early on tests performed by Anandtech seem to contradict Samsung'south claims. The Samsung 830 Serial drives measure 100 10 69.85 10 7mm and counterbalance 62.5 grams. The drives are backed by a express 3-year warranty.
