Abstract
Solid State Drives (SSD) can yield very high performance if it is designed properly. A SSD typically includes both a front end that interfaces with the host and a back end that interfaces with the flash media. Typically SSDs include flash media that is designed with a high degree of parallelism that can support a very high bandwidth on input/output (I/O). A SSD front end designed according to a traditional hard disk drive (HDD) model will not be able to take advantage of the high performance offered by the typical flash media. Embodiments of the invention provide improved management of multiple I/O threads that take advantage of the high performing and concurrent nature of the back end media, so the resulting storage system can achieve a very high performance.
