The new WD Blue and WD Green solid state drives are the first product of Western Digital’s acquisition of SanDisk in May 2016. However, it was not Western Digital’s first acquisition of a solid state manufacturer, or even their first solid state drive.
Western Digital acquired the SSD manufacturer, SiliconSystems and released the WD SiliconDrive family in 2009. However, the SiliconDrive family didn’t gain much traction. The SanDisk acquisition though was much larger and far more substantial. Western Digital not only gained access to a wide array of SSD and NAND intellectual property, they now have a substantial and stable NAND flash supply.
Today, we are going to take a look at their top-of-the-line solid state drive – the 1TB WD Blue SSD (WDS100T1B0A), which features SanDisk’s second-generation 15 nm TLC NAND technology. Check it out!
