WD SiliconEdge-Blue SSD Review
Western Digital has been the leading name in consumer storage technology since the early 1970's. Just in time for their 40th anniversary, the WD SiliconEdge-Blue Solid State Drive debuts as the first consumer SSD they've ever offered. Based on the JMicron JMF612 SATA-3Gbps SSD processor, the SiliconEdge-Blue promises 250/170MBps read and write transfers with 5000-4KB IOPS. In this article Benchmark Reviews tests the WD SiliconEdge-Blue SSD, 256GB model SSC-D0256SC-2100, against a myriad of high-performance solid-state enthusiast storage devices.
In a very short time span the entire SSD market has created and recreated itself many times over. Counting the generations of SSD processors has become difficult for experienced experts, and keeping-up with controller architecture has come with its own set of challenges. Benchmark Reviews has tested dozens of Solid State Drive products, and we've seen everything from dual-SATA controllers in RAID-0 to extremely large cache buffer modules used inside of them.
While the SSD industry grows daily, only a few select manufacturers offer popularly-accepted Flash NAND SSD controllers. As of April 2010 the most popular consumer SSD controllers are designed by: Indilinx, Intel, JMicron, Toshiba, Samsung, SandForce, and Marvell. In this article Benchmark Reviews tests the JMicron JMF612 processor, which is used in the WD SiliconEdge-Blue SSD by Western Digital.
For decades, the slowest component in any computer system was the hard drive. Most modern processors operate within approximately 1-ns (nanosecond = one billionth of one second) response time, while system memory responds between 30-90 ns. Traditional Hard Disk Drive (HDD) technology utilizes magnetic spinning media, and even the fastest spinning desktop storage products exhibit a 9,000,000 ns - or 9 ms (millisecond = one thousandth of one second) initial response time. In more relevant terms, The processor receives the command and waits for system memory to fetch related data from the storage drive. This is why any computer system is only as fast as the slowest component in the data chain; which is usually the hard drive.
The theoretical goal for achieving optimal performance is for system memory to operate as quickly as the central processor, and the storage drive to operate as fast as memory. With present technology this is an impossible task, so enthusiasts try to close the speed gaps between components as much as possible. Although system memory is up to 90x (9000%) slower than most processors, just consider that the hard drive is an added 1000x (100,000%) slower than that same memory. Essentially, these three components are as different in speed as walking is to driving and flying.
Solid State Drive technology bridges the largest gap. The difference a SSD makes to operational reaction times and program speeds is dramatic, and takes the storage drive from a slow 'walking' speed to a much faster 'driving' speed. Solid State Drive technology improves initial response times by more than 450x (45,000%) for applications and Operating System software, when compared to their HDD counterparts.
