Installation:
No problem, flap laptop eliminator, HDD cage out screwed hard drive out and repeated the whole thing in reverse order, was a matter of about 10 minutes.
Speed:
The speed boost is compared to the old record enormous.
Copy operations now need about 1/3 of the time, the startup process has accelerated by more than a minute to just 20 seconds.
I must say that I run the drive to a SATA 2 port, ie it does not even have their full "power" available.
Volume:
But what most impressed me the silence. On my old hard drive jerking and whirring was constantly heard, now the laptop is completely silent in normal work (to my ears)
All in all I can recommend an SSD without restrictions, a full five stars from me!
