Silicon-Power Velox V20: High Performance 2.5” SATA II SSD

In today's review we will consider another Silicon Power product. It is the Velox V20, high-performance Solid State Disk, characterized by a good balance between price and performance, SATA 3 Gb/s interface, 2.5 form factor and SandForce SF-1222 controller.

CrystalDiskMark 3.0.1

CrystalDiskMark is a very useful software to measure performance in reading and writing sequentially (sequential) and random (random), with full support for NCQ (Native Command Queuing). In the last test the order of input and output is optimized to improve performance with a Queue Depth (file queue) of 32. This test allows to observe the behavior of the drive when transferring many small files.

The latest version of the program currently available is 3.0.1. Recall that in versions 1.0, 2.0 and 2.1 were found critical bugs so they are strongly recommended.

In normal mode we have an average of just over 200 MB/s using the sequential mode. Good performance in 4K QD32. In sequential mode the 0-fill results are close enough to those declared.
