Have installed in my old IBM T23 laptop the plate. I wanted to improve the performance of the old treasures (at lower power consumption, less noise and less heat). After installation, I realized that was the plate with WIN-XP extremely slow (well below 10MB / second). The old Hitachi disk with 7200 U / min contributed as much more. By googling I found out that partitions must be aligned to MB boundaries and no longer on sector boundaries. Because Win XP can not do that, I have aligned in accordance with a separate program the partition. After re-install Win-XP was now achieved the performance of the old Hitachi drive. After two months of use, the write speed can but after again. Googling brought to light that the data must be even "trimmed" stored on disk, so that the performance is not breaking. A feature that only Windows 7 has. So let's just improve the performance of an old system with a new SSD was a shot in the oven. At best, I reach the performance of the old board. The battery life has remained about the same. Noise caused by the fan and not from the hard disk. My recommendation: Better choose a new system with SATA interface and a new operating system.
