Silicon-Power V20 Velox: Technical Specification

The storage unit produced by Silicon-Power is a product with interesting features. Let's see them up close:

The V20 Velox uses a penultimate generation controller produced by SandForce, well-known company that is specialized in this type of product. In particular, as already seen in the analysis of the controller, this unit is equipped with an SF-1222TA3-SBH. This controller provides high performance compared to traditional mechanical disks but also compared to older first-generation SSDs. The company reports a value of only 13 seconds from the boot phase to a full Windows startup. The presence of Trim and GC technologies also allow to maintain its performance over time, and avoid the performance deterioration typical of the first SSD with old controller.

The SandForce controller guarantees, thanks to DuraClass technology, a much higher life expectancy than traditional SSDs. Moreover, as already shown in previous pages, we get an included adapter from 2.5" to 3.5" in order to house the unit in any cabinet at our disposal.

The PCB is equipped with well 16 flash memory chips, 8 on each side. Each chip has a capacity of 4 GB but, as you might guess, this way we go beyond the 60GB SSD offered by the unit, to be exact the exact amount of memory is 64 GB.

This difference between the amount of available memory and memory used is actually caused by overprovisioning technique, which dynamically allocates more space to replace the cells that are no longer functional.

NAND flash memory modules are classic FG-MOSFET transistor type multi-layer cell that carry the serial number Intel 29F32G08AAMDB. They are 34nm MLC, generally long-lived than the new 25nm chips.

We analyze the technical specifications of the Velox V20 Solid State Disk unit:

• Transfer rate: 285MB/s maximum read, 275MB/s maximum write
