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 !
