By sdd do you mean ssd and is sat3 a SATA 3 HDD (SATA is just an interface)? If so that is a HUGE FREAKING difference, far more than the CPU and RAM (unless your entire app and database fit in RAM). SSD's are orders of magnitude faster than disks, particularly for random I/O which is the bulk of what web servers and databases do. SSDs can do upwards of 90,000 random operations per second while disks can do somewhere around 100.

yes, sorry lots of typos in my previous post Dodgy

it was SSD now it's HDD with SATA3 interface. However, I now have 8Gb RAM vs 2Gb before, and all my website is cached in RAM, so that the HDD should not have any negative impact. In fact I find my website much faster now on the new server (the opposite would have been quite upsetting considering I'm paying twice as much!)
