This week I got myself an intel SSD 750 series SSD (400 GB) for my Dell Optiplex-9010 desktop PC. A machine that is almost 3 years old now.
It has an Intel i7-3770 CPU (4 cores + hyperthreading) and 32 Gigabytes of RAM. I already had a small 128GB SSD in that machine.
To increase performance and to bypass the SATA2 bottleneck, I decided to get the 750SSD, which comes as a PCI Express Card (Gen 3 x4)
