Ok, because of this post I had to try a Intel SSD. So I bought this one here. I moved all my data over like this. It all worked well and now I am running on my new SSD. And there is a big difference. So a quote from here is totally true:
If you’re curious, it’s the random write performance that you’re most likely to notice and that’s where a good SSD can really shine; you write 4KB files far more often than you do 2MB files while using your machine.
Also Startup-Time of your computer is crazy fast! I can hardly see my Gentoo-Message while BootUp anymore. If your are on Linux, also consider these options for fstab and booutup: noatime, elevator=noop. But read more of your own in the above mentioned links.
Update: There is a newer, faster and cheaper version out now: X25-M G2

Afer I saw Linus’ post some weeks ago I knew you will buy one once a day 😉 Have fun with it – I’m very happy with my SSD as well with my MB Air, although not with the famous Linus featured Intel drive…
Ok, if your Intel SSD came preinstalled with an OS you should Secure-Earse it. I done that as well for our new Linux Server. Use HDD Erase 3.3:
