Lenovo T420s upgrade

My Laptop is a Lenovo T420s with 8Gb RAM and a 7400 rpm SATA disk.

I’m using lots of virtuals machines, especialy for BlueMind development and clients projects, and sometimes my laptop is overloaded.
There is mainly 2 bottleneck:

  • SATA disk IO/s
  • swap operations, which increase SATA disk IO/s

So, I decide to upgrade my laptop using:

  • SSD 500Gb: Samsung 840 series – MZ-7TD500
  • 16Gb RAM: G.Skill SO-DIMM DDR3 2×8 Go PC10600 SQ

Speed-up is pretty impressive !
