Better than standard, but smaller

I bought the SSD to tune the "old" laptop. The SSD is as expected, quickly.
The latest firmware update to 1.5 was difficult, first went with the OCZ tools Boot CD, not on Vista.
Since the SSD is smaller, had movies and music on an external 2.5 "disk.
The high speed is quite noticeable in all walks of life, from booting up to multitask. Previously the disk was the bottleneck, now it is the processor (Core2Duo).
However Executed benchmarks show substantially lower throughput rates to, as advertised, namely rather ~ 200MB / s
Also IO / s are much smaller. Can I speculate whether the situated at the old laptop. In practice, the plate is sauschnell! No comparison to previously. Windows 7 boot after BIOS goes into what felt like 15 seconds. Ubuntu Linux is even faster.
