WD Explains Its Windows-Only Software-Based SSHD Tech 286

crookedvulture writes "Seagate and Toshiba both offer hybrid hard drives that manage their built-in flash caches entirely in firmware. WD has taken a different approach with its Black SSHD, which instead uses driver software to govern its NAND cache. The driver works with the operating system to determine what to store in the flash. Unfortunately, it's Windows-only. You can choose between two drivers, though. WD has developed one of its own, and Intel will offer a separate driver attached to its upcoming Haswell platform. While WD remains tight-lipped on the speed of the Black's mechanical portion, it's confirmed that the flash is provided by a customized SanDisk iSSD embedded on the drive. The iSSD and mechanical drive connect to each other and to the host system through a Serial ATA bridge chip, making the SSHD look more like a highly integrated dual-drive solution than a single, standalone device. With Intel supporting this approach, the next generation of hybrid drives appears destined to be software-based."

To be fair most people that need that serial port either are interfacing with 3.3V logic or have a pile of 3.3V->USB serial converters in their junk box. At least the BeagleBone follows the FTDI convention so that many of the off-the-shelf converters will Just Work, unlike the competition.

Say you had a VW Microbus, and the insides of the windows are permanently fogged with antifreeze from a leaky heater core. You lend your friend Eddie the Microbus for a few days, but before he picks it up you write "frist psot" on the front passenger window. After a day of driving it, Eddie loans it to his pal Joe to move a couch, but before he gives it up he writes "hot grits" on the back window. Joe adds "STFU noob" to the windshield, but before he has a chance to move the couch, his grandma needs to borrow the Microbus to get to a bingo tournament. This goes on and on for years. Eventually you get your car back, with every window covered in messages.

Now imagine there are hundreds of thousands of VW Microbuses in your pants. This is what's happening in Cuba.
