[/quote]The only way you get 3Gbps speeds from spin drives is when they read from the HDD cache. a hdd physically can't spin fast enough to output data at even 1.5Gbps.

hard disk drives[/url] can transfer data at up to 127 MB/s,[7] which is within the capabilities of the older PATA/133 specification. However, high-performance flash drives can transfer data at up to 201 MB/s.[8] SATA 1.5 Gbit/s does not provide sufficient throughput for these drives.
