The proven lethal effects of NAND Flash on other portable media also point to the current controversy between SSD and HDD advocates. Hard disk drives retain their lead over SSDs in storage capacity and storage cost/bit and HDD vendors continue to move heaven and earth to maintain that lead. SSD vendors seem just as eager and determined to overtake HDD vendors and the historic record of NAND-Flash-based storage devices’ ability to kill older, competing media formats is pretty compelling. Already, enterprise-class storage systems are finding compelling applications for SSDs as storage accelerators. Leading-edge PC users including gamers and video producers find SSDs compelling for their speed, albeit at a higher cost for storage. Today, SSDs are mostly used as HDD helpers. Tomorrow may be another story. It obviously won’t happen next year or even the year after that, but I wouldn’t bet against the ultimate outcome.
