    I don't think they are common enough for us to have any experience with them yet.

    If they have similar characteristics to PC RAM, then they should do quite well in the winter. Although many car PC's are operated below the manufacturer's spec temperatures, I'm unaware of any instances where a very cold PC board has failed due to the RAM.

    Sometimes they won't boot because of shrinking/expanding connectors and so forth, but that is *probably* less of an issue with an SSD. I think SNO is probably right when he says that it will be at least as reliable as a current drive and I would expect it to be more reliable in the cold.

    Main issue with cold is/was fluid bearing hard drives get so close to freezing they can't be spun by the HDD motor. This usually fixes itself after the HDD heats up a bit. Second problem is the LCD monitors with CCFL are very dim at first until they warm up.

    SSD *should* be the least of your problems but nobody knows at the moment.

    I've have cold boot problems with my 3.5" drive, but this coming winter will be the first with my SSD, but i'm confident it'll work flawlessly. I don't think it gets -20 here, but I'll let you know how it does if you wait that long. If not, stick one in your freezer and try to boot it

    I have been searching mp3Car forum and I had not found this thread. It answers some of my questions and ideas.
    Thanks for this link

    I am starting to think that SSD will not give me so much problem. It rarely goes down to -20c here in Iceland. Very often it is around -5c

    If anyone needs a hard drive for the cold, I've got a new 80GB EE25 automotive grade drive for sale.

    I tried an OCZ Summit which works even in -40C, but anything below -15C it's speeds went from 100+ MB/s down to less than 10 MB/s. Ive read that some SSDs dont work at all in the cold while others have no problems. Im going to wait until more people comment on what models of SSD work properly before going solid state again. Until then Im sticking with dual EE25 drives which have never had problems even in -40C.

    One other thing to consider is the controller/motherboard which the drive is connected to. Although chips are solid state, they can fail to work in the cold as well. I know for certain that my EE25 drives are good down to -40C when hooked up directly to my motherboard, but I had one hooked up to a 2.5" to USB adapter (Vantec brand) and the drive failed to spin up. I then hooked it up to another adapter (generic brand) and no problems.

    Go to the manufacturer websites. I only looked at OCZ and they have all the specs there. They all look the same:
    Operating Temp: 0C ~ 70C
    Storage Temp: -45C ~ +85C

    So you could probably assume a little beyond those numbers, but at -40 I'd think it might reduce the life heating and cooling down often. Still a much better option than a mechanical drive.

    Shock Resistant up to 1500G. I think we need to test that.

    Yeah, all consumer grade stuff are 0 and above, but a certain brand will do fine in the cold. If you want anything rated for -20*c or lower then prepare to pay a hefty amount for it.
