The problem
Laptops equipped with Intel 5 Series chipset like PM55 and HM55 experience low SSD performance and specifically low 4K random reads and writes as well as low access times.
Comparison with a different chipset
The hardware we used to compare the SSD performance is the following:
SSD: Intel X25-E 64GB
Laptop #1
Dell Alienware M17x R1
| Chipset | NVIDIA MCP79 | |
| CPU | Intel QX9300 @ 3.2GHz | |
| RAM | 4GB Kingston HyperX DDR3 @ 1333MHz CL7 |
Laptop #2
Dell Alienware M17x R2
| Chipset | Intel PM55 | |
| CPU | Intel i7 940XM @ 3.44GHz | |
| RAM | DDR3 4GB Kingston HyperX @ 1333MHz CL7 |
OS: Both laptops had MS Windows 7 Professional x64 installed with the latest drivers at that time.

Note that the read access times are 2.86x times slower and the write access times are 3.51x times slower on the R2 compared to the R1
