    Do you have Ubuntu + LUKS on a SSD hard drive?

    I would like to buy a SSD hard drive and install ubuntu + LUKS on it.
    But first I'd like to hear the advices from someone who has already done it.

    I only use this programs:
    - firefox
    - openoffice
    - virtualbox (with some wxp and w7 guests)
    Before we wish or believe in something, we must know that that something exists and is real

    Advice on what ?

    I have Fedora and Slackware on SSD with LUKS, what is your particular concern or question regarding Ubuntu ?

    Well, I just want to know if there is any danger of data corruption, because I've read somewhere that SSD drives have write limits (sorry for not being able to explain im more detail).

    That, in conjunction with LUKS and virtualbox makes me think twice before jump into SSD scene..

    People say the same thing about USB flash drives, I have one from about 10 years ago which has gone through the washing machine twice and still works fine

    You will be fine, no concerns IMO, you will want to look at SSD optimisation though with things such as noatime and TRIM.

    Here is a primer to get you off on the right foot to ask specific questions once you have one etc http://apcmag.com/how-to-maximise-ss...with-linux.htm

    I use 2 SSD in my main system, one for multiple OS and one for backups and I use a 3 x 2TB HDD for data storage (primarily as the larger size mechanical HDD are cheaper)

    My system is on 24/7

    There are no issues IMO.

    Enjoy

    They do, but in practical terms so do old-fashioned spinning drives. No drive will last forever, but SSDs do have wear-levelling algorithms that ensure that the drive doesn't write to the same spot too often and wear it out. Many people (including myself) have been working SSDs hard for years now, they've proven to be at least as reliable as spinning drives (probably considerably more so in fact).

    In short, don't worry about it. Carry out some of the optimisations alluded to above to improve performance, but limited writes isn't something to worry about unless you have one of the ropey old first generation drives such as those in the early Eee PCs.

    Thank you both very much

    That kind of information and first hand experience was what I exactly what I was looking for!
