Western Digital’s SiliconEdge is the brand’s first solid-state storage solution for the consumer market, and its 'Blue' tag is a hint that faster drives may be around the corner.

Western Digital’s SiliconEdge is the brand’s first solid-state storage solution for the consumer market, and its 'Blue' tag is a hint that faster drives may be around the corner.

While many SSD units are appearing from memory or other semiconductor specialists, the SiliconEdge Blue is the product of a heavyweight in the old-school hard disk arena. Western Digital’s SiliconEdge is the brand’s first solid-state storage solution for the consumer market, and its 'Blue' tag is a hint that faster drives may be around the corner: Scorpio Blue is WD’s midrange hard-disk range, with Scorpio Black standing above.

At 109g, the WD SiliconEdge Blue is no lightweight itself, weighing the same as a regular 2.5in laptop drive. Construction may be solid in in what appears to be a brushed stanless steel jacket, but this isn’t an SSD you’d chose to shave a few grams off your laptop’s mass.

Running the WD SiliconEdge Blue’s show is a JMicron JM618 controller and 64MB of cache.

In performance terms, the WD SiliconEdge Blue was relatively lacklustre - although it would still give a traditional hard drive a good thrashing. Sequential reads in HD Tach and HD Tune Pro were 200MBps and 190MBps respectively, but write speed was comparatively low at 103MBps and 86MBps in the same tests.

CrystalDiskMark again hinted at good headline sequential speeds (243/185MBps), but the WD SiliconEdge Blue saw no real lift with the 4kB-QD32 benchmark: 19MBps and 17MBps read and write speeds.

In the more modern AS SSD sequential transfer test, the WD SiliconEdge Blue performed much faster, achieving 241/176MBps for read/write performance. But small 4kB files lagged a little at 15MBps, and with no respite when a series of these files were queued up.

  • Overall: We give this item 7 of 10 overall

The WD SiliconEdge Blue is solid but heavy. Performance is good, but it's a little less impressive when the SSD is asked to multitask with a series of smaller files (a common task for a computer’s OS to field).
