That drive is a Kingston A400 SSD and is much faster then a hard drive will be even for the foreseeable future. It reads data at over 500MB/s and writes at over 300MB/s. This drive has no moving parts and therefore does not have an RPM specification to go with it.
While this maximum speed spec is for large sequential data, it is only about 2-3 times faster then a harddrive. But this is not where it will shine compared to an HDD. HDD's really suffer when reading or writing random files. The heads must travel all over the disk and really slows the reading/writing process down. SSD's, having no moving parts, they simply have to address the new internal flash memory location and end up being about 100 times faster then a hard drive.
