To finish off the story - i have received the Samsung 830 128GB today - cloned the standard disk with Acronis - mounted the SSD drive ....... and MY GOD!!!!! It is fast - i am very impressed, boot time is about 20 sec. and experience index say disk performance = 7.9.
I am a very happy man today!

I also have the Samsung 830 SSD (128 GB) with Ubuntu 11.10 in my X220 (BIOS 1.21) and I am so far very happy with it. There are two things I want to ask/point out though;
When I am docked (Mini Dock 3 Plus, 90W PSU) I get read speeds (hdparm -t) between 260 - 350 MB/s depending on my power scheme (Powersave < On Demand < Max performance) - the variation in speed with power scheme is strange, but not as strange as:
When I am on battery, I get (the expected) read speeds of 450 - 530 MB/s
(again depending on the power scheme; Powersave < On Demand < Max performance)
What do you make of this? I am baffled - when docked, the system should have all the power it needs... why slow down?
Now that you have put SSDs in you X220s, they should be very quiet. However, if I put my ear to the keyboard I can hear a noise very much like the seeking noise of spinning hard drives, only more quiet - it is definitely coming from the area of the SSD and I can reproduce the sound by running hdparm -t.
Can you guys please listen closely to your disks and tell me whether they make this sound ?
(run Crystalmark or some other HD test software if you are using Windows)
What is more, I can hear the processor squealing when doing the same tests - a noise that gets lower and then disappears on the more conservative power schemes (On Demand and Powersave)

Thanks for your reply orion9727 - I think I have eliminated most of the eventualities you mention, and the X220 has had some power issues before, which could explain the stranger SSD performance behaviour.
On a side note; I do not share your opinons on Linux capabilities regarding SSDs and such (e.g. TRIM is supported, although best manually at this point), at least as long as they are not substantiated by yourself or the community. You are right though that SSDs have been well integrated into Win7.
Could anyone who has the X220 with the Samsung 830 SSD or any other SSD please have a close listen to their motherboards/disks - You will need a dead quiet room and to put your ear to the keyboard, as well as to control your fan speed/noise to be able to distinguish.
Thanks in advance, it is much appreciated!

I've just bought & installed a 256gb Samsung 830 SSD for my new X220. My power scheme is "energy saver" and i've not changed any factory default settings. The only sound i can hear is from the fan and even then i have to put my ear right next to it in order to hear it.....ie its a low whine. There is DEFINITELY no noise coming from the SSD drive area.
On a slightly different note, when my notebook boots up, Samsung Magician v3.0 displays a pop-up message saying that "magician update available" and yet when i click on this, it just takes me to the samsung ssd website and i can't find any newer versions that 2.0. Anyone else get this?

I have read that RAM sometimes makes noise. If you have >1 stick try removing one at a time and see if that helps.
