ADATA S511 60GB 6Gb/sec Solid State Drive Review

Storage/SSD by stefan @ 2011-10-17

The ADATA S511 60GB SSD offers high read/write transfer rates on SATA3, making it a product to consider when deciding to boost the overall system performance. It comes with the Sandforce SF-2281VB1-SDC processor and 25nm NAND flash, ADATA offering for it with 3 years of warranty.

A Closer Look Contd.

On the back of the SSD, we can find some serial numbers, along with the warranty code:

 

 

 

On the same side, we can find the SATA power and data connectors:

 

 

 

On the PCB, we can find 8 Intel MLC 25nm 29F64G08AAMEI Flash modules:

 

 

 

 

The heart of the SSD is the SandForce SF-2281VB1-SDC, which interacts directly with the modules (there is no need of additional RAM). The processor comes in a 256-pin TFBGA package, supports Flash capacities from 12GB to 512GB and can work with both MLC and SLC Flash types:

 

 

 

 

The SF-2281VB1-SDC processor have integrated enhanced DuraClass technology that is architected to leverage today's densest SLC and MLC NAND flash memory. The processor is built to deliver best-in-class performance, endurance, security and power efficiency in a “DRAM-less”, single chip solution.

The incorporated DuraWrite technology optimizes writes to the Flash memory over conventional controllers increasing the overall endurance and reliability of the complete SSD. Highly intelligent block management and wear leveling also extends the overall endurance.

SandForce SSD Processors deliver performance that maximizes the throughput of a 6Gb/s SATA interface with balanced read/write speeds.

DuraClass technology automatically stores data in a highly secure AES-256 & 128 hardware encrypted format that double encrypts the data.

The SF-2200/2100 SSD Processors provide data protection that surpasses the leading high performance enterprise HDDs used today. This comes from a combination of a superior higher-level BCH ECC algorithm with up to 55 bits/512 Byte sector protection and the unique RAISE (Redundant Array of Independent Silicon Elements) technology. RAISE provides the protection and reliability of RAID on a single drive without the 2x write overhead of parity.
