Got the SSD for some time as an offer for 70 before - bought at Saturn. Built as a substitute for a 120GB HDD in my about 7 years old Fujitsu LifeBook T4220 (Convertible with Core2Duo with 2x 2.6 GHz, 4 GB RAM, SATA II). I have deliberately taken this SSD: 1. Very high write speed when compared to the same size other SSD. 2. deliberately chosen twice the capacity, to allow faster access (without which I exactly understand the technical background: an SSD should have significantly more free space than a HDD). Very easy installation, operating system and programs reinstalled. Success: The laptop starts definitely much faster than before (I have not measured it there, but have the comparison with another similar machine that still has HDD). The battery life has been extended considerably. The machine is used to usable (with HDD I did after the start is always a "coffee break" in the access to the HDD ausbremste everything - that's gone now, the Task Manager shows clearly that the SSD in the period before her "buggers". and other system components are clearly the required). From me strong buy recommendation!
