Non-rotating media
Windows 7 detects SSDs by using ATA8-ACS identify word 217: Nominal media rotation rate, with value 0001h as Non-rotating media like solid state devices. But not all SSDs adhere to the ATA8-ACS1 spec section 7.16.7.77, some may need firmware updates.

Seek Time
Unlike a magnetic rotating disk, the SSD has no read/write heads or platter. There is no seek time or
rotational latency issues. Zeus SSDs dramatically improve transaction throughput, particularly for
applications that are configured to take advantage of the characteristics of the drive.

WINDOWS 7
The random read threshold test was added to the final product to address the fact that few SSDs on the market today properly identify themselves as SSDs. 8 MB/sec is a relatively conservative rate. While none of our tested HDDs could approach 8 MB/sec, all of our tested SSDs exceeded that threshold. SSD performance ranged between 11 MB/sec and 130 MB/sec. Of the 182 HDDs tested, only 6 configurations managed to exceed 2 MB/sec on our random read test. The other 176 ranged between 0.8 MB/sec and 1.6 MB/sec.
