Kingston V series SNV425S2128GB, 128 GB

It is but recently that we reviewed the first-generation V series from Kingston and now we have a second-generation model in our hands. The differences are dramatic. While its predecessor was based on a JMicron 602B controller, the second-generation V series features the newer Toshiba TC58NCF618G3T, which is a slightly modified version of the JM618 controller. This SSD has MLC flash memory and 64 megabytes of cache. It is declared to support TRIM. The 128GB model is specified to have a read speed of 200 MBps and a write speed of 160 MBps. The lower-capacity models (30 and 64 gigabytes) are somewhat slower at writing.

The firmware version of this SSD is C091126a.

Major HDD makers couldn’t neglect such a rapidly developing and potentially dangerous market of solid state drives but were not among the pioneers of it. It is only recently that they have begun to produce SSDs of their own. Western Digital is at least ahead of its main rival Seagate in providing SSDs for us to test.

The first thing you can note about these products is the word Blue in the series name. Western Digital’s HDDs fall into three main series and the Blue series is not the fastest among them. Thus, we can expect this manufacturer to produce a Black series in the future which has to be even faster. As for the Blue series, it currently includes three models with capacities of 64, 128 and 256 gigabytes. They are all based on MLC memory and a JMicron 612 controller, possibly modified by Western Digital, which is backed up by 64 megabytes of cache. The series is declared to support NCQ and TRIM and deliver peak read and write speeds of 250 and 170 MBps, respectively.

These SSDs both have the same firmware version: 5.12.
