For quite a long time Samsungs SATA-II PM470 had to compete with much faster SATA-III SSDs. But finally Samsung managed to bring their PM830 SSDs to the market which now also comes with a 6 Gbps interface. Furthermore the drive should also offer very high IOPS regarding read operations.

Behind the scenes

Finally, with the PM830, Samsung has a SATA-III SSD in its product portfolio. The core of this Solid State Drive is a furhter development of the controller Samsung has already used for the PM470. Meanwhile it is based on a triple core ARM CPU but unfortunately that is almost as much information as Samsung discloses. Regarding specific algorithms there is no further information.
The fact that Samsung still uses a page mapped architecture with the PM830 SSD require quite a big cache. In this case Samsung uses a 256 Megabyte DDR2 Chip to buffer a sufficient amount of data. A closer look at the flash memory reveals that Samsung uses its own 2x-nm Toggle-DDR-NAND that offers 133 Mbps per Interface. To get a reference: ONFi 2.x NAND offers a similar performance level.


The test sample that reached our office arrived nicely cushioned in a plastic box but that was about it. the retail version Samsung sells to end users also comes with a 2.5-to-3.5-inch adapter bracket as well as a full version of Notron Ghost 15.0.
Samsung is especially proud of the PM830s nice design. The drive comes with a hairline brushed aluminium plate and therefore leave a very good optical impression.
