Data storage capacity and performance requirements are increasing for businesses of all sizes. While conventional hard disk drives can meet capacity requirements, hard drive (HDD) performance enhancements have remained relatively flat and confined to the rotational speed of the media. Hybrid hard drives(HDDs) offer accelerated performance by utilizing integrated NAND flash to cache data. The result is significantly improved performance over today's conventional hard drives(HDDs).- 6 Gbps Hot-Swap and Simple-Swap SAS for optimal performance and system availability- 2.5-inch 600 GB 10,000 rpm hard drives(HDDs) offerings- 16 GB NAND flash to cache "hot data"- Fine tunes storage tiering by caching at the I/O level
