On the bottom we can find another large sticker, with the model code name, serial number, currently installed firmware, voltage rating and some warnings:

On the top side of the SSD PCB, we can find eight NAND Flash chips, along with the Sandforce controller:

The back side has the rest of the NAND Flash chips:

As the previously reviewed SSD from ADATA, the PYRO also comes with the SF-2281VB1-SDC controller model, which comes in a 256-pin TFBGA package and supports Flash capacities from 12GB to 512B, being able to work with both MLC and SLC Flash types:

The NAND Flash used is manufactured by Micron and comes with the 29F64G08CBAAA serial number; these have a capacity of 8GB/chip and integrate MLC (multi-level cells) on the 25nm process. About 8GB of space is used for provisioning (wear leveling and garbage collection):

The SF-2281VB1-SDC processors also 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.
