The bottleneck in flash storage is often the interface. SAS/SATA interfaces were designed specifically for hard disk drives not for flash media. For example, flash storage can support many more simultaneous I/O operations. The resolution to the problem is to use a different interface, one that is higher throughput and is more directly accessible from the CPU. Leveraging one of these interfaces and extracting optimal performance from the flash media means leaving the confines of the SCSI protocol with customized proprietary drivers. The result is complexity and slow innovation.
