Hi,
I held of getting an SSD for years.
I just bought a new laptop (W230SS- i7 4700m, 860M etc), which came with a 1TB 5400RPM drive. I installed W8.1 (on the mech drive) and everything ran quickly and smoothly.
I then bought a mSata SSD (Samsung Evo 840). I was very excited to see a 'massive' difference in my day-to-day activities. I wiped the 1TB drive, and installed W8.1 onto the mSata (of course).
I'm quite disappointed. Boot time isn't much quicker, and programs hardly load faster.
Is this because my mechanical hard drive is brand new, so realistically it would start slowing/lagging soon?
Run Crystal Disk Benchmark on both drives, and post up the results. Maybe something went wrong. Is your SSD aligned properly, for instance? Is Windows actually installed on the SSD and not on the HDD?
