Tha an draibhear seo a’ nochdadh V-NAND 64-layer ùr Samsung agus rianadair àrd-choileanadh a lìbhrigeas suas gu 3,000 MB/s de thoraidhean leughaidh leantalach agus 270,000 random read IOPS.

Chaidh rianadair cuimhne Samsung Polaris V2 a chleachdadh anns an dreach tràth, but ARM Phoenix memory controller was used in the later version.

It was popular for a while because of its good value for money.
