Introduction

A-DATA, most well known for their world-class DRAM memory has ventured into solid state storage a few years ago. Their enthusiasts products are centered around Sandforce's flash controller offerings. The new A-DATA S511 SSD uses Sandforce's new SF-2281 controller chip, which is the fastest the company offers. A major improvement of the ADATA S511 SSD is support for the SATA 6 Gbps interface which promises significantly improved transfer rates compared to the SATA-II interface. A-DATA's S511 is available in capacities of 60 / 120 / 240 and 480 GB. We tested the 120 GB model of the ADATA S511.

Packaging

ADATA's package comes with a small window which lets you take a look at the capacity printed on the SSD. This is a clever method, so ADATA does not have to print different packaging for each model. All important product specifications are easily visible on the front, with more detail on the back.


You will receive:

• The SSD
• Documentation
• 2.5" to 3.5" adapter

The Drive

The drive conforms to the dimensions set forth by the 2.5" form factor. It uses a rugged metal casing that feels extremely solid and high quality.


ADATA's S511 uses the SATA 6 Gbps interface. It is compatible with any other SATA standard, but will work at reduced performance in such a case.


ADATA is using 16 flash chips and the Sandforce flash controller, which is located in the middle of the PCB. An additional DRAM cache chip, like other SSDs use for additional caching, is not available.


As controller the recently released Sandforce SF-2281 is used.


The 16 flash chips are made by Intel and have a capacity of 8 GB each, they are produced in a 25 nanometer production process.
