    4TB data written is absolutely tiny. So, that is a *very* low write system in my view.

    This is totally off topic.
    I work for a private company not a school (boo!), I want to go about things the right way on here.
    I do not want to be a spammer and will enjoy the tech debates (like this) but would like to know who I would need to contact to look at sponsorship of the site. I had emailed web admin a couple of times but I presume that is spammed to hell anyway. I would be a liar if if I said some of the opportunities on here were not of interest, but also having been dealing in education for over 15 years I want to go about things the right way.
    So unfortunately that will still mean you get my bad opinions on hardware matters.

    This would be a case of setting up system monitoring of SMART data, giving an alert when the "usable life" attribute drops below a certain level (I'd go for 25% just to be safe, maybe higher).

    Some SSDs (Kingston SSDNow E100 for example) do not support TRIM at all and rely on having aggressive GC routines, so it really depends on the SSD.

    Off topic, ban him, ban him

    I'd try PMing @Dos_Box as a starting point... if he doesn't know, he'll know a man who does

    Cheers.

    But on SMART I would go for Below 50%, from experience they start running like a dog at that level.

    I think on the desktop the break is now. The OS drive on a server, the break is probably now. For the rest... Well I'd personally like to see a couple of more things happen first:

    1) RAID support
    2) Longer Warrantys
    3) A couple of decent reviews that say "this drive won't die after x number of writes)
    4) Prices to drop a little more.

    To be honest, we're almost there. I can't see magnetic disks still being popular in 5 years or even available in 10 years. I just don't buy the argument that these drives are so uber reliable that you don't need RAID, besides that's whats back ups are for. No, I like my RAID security blanket, thank you.

    Exactly my point.

    Both SQL and file servers dont read/write much data at all.

    Our Sims server is used everyday for registration in a school for 1000 pupils. The actual DB size is over 2gb now. I doubt if it goes over 100mb of data actually written a day. Our file server is less than 2gb from my 24hr test since yesterday.

    1) RAID support - See @Arthur's point above
    2) Longer Warrantys - most decent ones tend to have 3-5yr warranties (same as HDDs)
    3) A couple of decent reviews that say "this drive won't die after x number of writes) - trying to find some reviews currently... manufacturers are being more forward about this now.
    4) Prices to drop a little more. - prices are dropping all the time (see ebuyer's £30 60GB SSD last week, and someone reported a 120GB cheap as well), Intel 520 is around the 50p/GB mark as well

    RAID, either stick some SSDs in RAID (see point 1) or use some network technology to "RAID" over network.

    Thanks to all the advice on this thread I have decided to go ahead with this. Current plan is:

    2 x Dell PowerEdge R320 with 600GB Intel 320 SSDs. Running Hyper-V + DFS
    1 x Dell PowerEdge R320 with 300GB OS Drive + 600GB Intel 320 SSD. Running Hyper-V + Backupexec 2010 + Veeam
    1 x Netgear GS724T gigabit switch

    Hopefully that gives me complete redundancy for our entire file system and 600GB to play with. Our current file server is around 220GB so this should give us loads of extra space for the future.
    We currently also have a Video and Audio server. I will keep this hard disk based for now.

    And here is the first pic of the change over. Bye bye seagate "enterprise" constellation. I won't miss your random failures!!

    This is the most fun I've had in years setting up a server.

    Just copied a 4GB .iso file from one server to the other. Took 15 seconds!! 150mb/s transfer.

    Wow!

    Got the parts for actual file server today and built the VM. Oh my word I'm in speed heaven!!

    117 MB/second!! Our current file server has never been above 20 Can't wait to see how long our normal 13hr backup takes at this weekend.

    Does anyone know how to get the aero interface on Windows 2008 R2? I've installed the desktop experience but can only really set backgrounds so far.

    thats all you do, i should imagine the server doesn't have a good enough graphics card to do it.

    Simple answer for any server that isn't a terminalserver (tbh i haven't even bothered on that front myself): You don't.
