    I am wondering for a low cost server solution for an organization of 50 users what drive type should be used. I lean towards SCSI cause that is what I have always used and I know it to be very reliable. but SATA is so inexpensive and the budget is tight. any ideas anyone?

    If I were to start from scratch, I'd say SATA too.

    when you consider capacity and cost, the solution is apparant : sata.

    SATA... not to be an ass, but do a search as I have seen this thread a few times. i think there is one good thread with a lot of info on this already

    If your budget is tight, SATA.

    Else, fiber scsi.

    Or get some used HSG controllers. They are reasonably priced now since they are discontinued, but still have a lot of ISV support. Overkill for 50 users though.

    If you have a board that supports 64bit PCI then SCSI. otherwise SATA.

    I just got a SATA RAID:

    works great for me, and didn't cost too much.

    very good I think i will go for the sata raid solution. also for anyone who is interested dell
    has just released a new server called the sc 1425 it is crazy cheap a little over eighteen hundred dollars. thanks for all the posts i think i just needed a little push to force me to make the right decision. thanks again everyone.

    for the money, the dell 1425 isn't very good.

    For most desktop/workstation/small server SATA...

    For enterprise level stuff, I had say that SCSI still got the edge, (of which you pay a crazy premium on). I can't comment too much on which interface is technically superior, I never studied their spec, read the whitepaper and dig into it. From what I understand though, serial interface is the way to go, and even the SCSI camp is moving toward that (iSCSI I think that it is called).

    SCSI traditionally had been offering some more exotic features such as command queqing, but we are see that in SATA as well. So, the question really comes down to the hard drives avaliable for each interface. I just don't know why they ain't making 15K drivers for SATA. Perhaps lack of demand? or some technical constrain...

    Didn't you already resolve to buy SATA?

    nope specter I hadn't made up my mind but i have now all i have to do is get my boss to agree. also why is the 1425 not worth the money jollyogre??

    You need to take in consideration what the server will be doing. If its just a file server SATA is probably a better choice (fewer larger reads). If you doing LARGE data bases or even smaller ones with ALOT of hits SCSI (lots of little reads) maybe the better route.

    Then there is reliability:
    "Whereas an enterprise-class SCSI drive has a mean time between failure (MTBF) of 1,200,000 hours, many SATA drives only run to 600,000 MTBF"
    http://storagemagazine.techtarget.com/strgTrend/1,291266,sid35_gci999961_login,00.html

    It is commonly known that manufacturers' rated reliability of ATA drives is 400,000 to 500,000 hours of Mean Time Between Failure (MTBF), while SCSI drives are rated for 1 million to 1.2 million MTBF
    http://www.varbusiness.com/sections/technology/tech.jhtml?articleId=18841251

    That price is not that great, even at Dell. The 1750 is a tried and true server and equally equiped w/SCSI over SATA is only a little more (Whats OT running on?). Or the 750 for a few dollars less with SATA... I suggest you go with Dell, I am up to about 48 servers (From 350 to 7250's) corporate wide and only failure (NIC was dead out of the box)

    Just remember if you buy cheap you get cheap.

    WD Raptor Drives compete with SCSI on speed and reliability.

    :rofl: Yes, but that's still like top of the line SATA vs budget SCSI drives.

    You think it's gonna hang with 15K drives? I don't think so.

    but take cost into consideration...

    show me a set of scsi drives and controller that beat some raptors for the price...

    Well in such case aside form the cost of controller...

    SCSI U320 15K 73G is about 2.5 to 3 times as expensive as the 74G Raptor..
    SCSI U320 15K 36G is about 2 times as expensive as the 36G Raptor.

    That's the price for performance I guess.

    Far as SCSI 10K vs SATA 10K goes... yes SATA is cheaper... no doubt...

    The SCSI cable for 4+ drives alone is :eek3:

    ebay is your friend for cables for SCSI. I got my 5 device round cables with therminator for like $10 CAD shipped if i can remember right. Its like 50 inches long too if thatsa good thing.

    At low budgets, there is no way SCSI can beat SATA. You pay more for SCSI because the companies have to pay royalty fees to use the interface. It is not because it costs more to make the hardware. Just get multiple drives in a raid config based on what the company needs. They don't all have to be fast drives, especially when there are only 50 people.

    I :love: SCSI. It's so damn elegant.

    If only it wasn't so damn expensive :embd:

    keyzs thanks for the links they were really interesting to read and I used them on my boss so now I got her to up my cash flow, with storys of burning sata drives and brimstone. so now I have it between a dell 2650 and a IBM x336 anybody used either of them before, any user pros or cons. from the specs the IBM is all up in the dell some thing fierce but all the enterprise level guys I know all ways complain about
    IBM's support. any ideas?? thanks again to everyone for giving such good information. i really appreciate it.

    I have a bunch of IBM x-series and their support was abysmal. Worse than Dell's. I'm in the process of phasing out our IBM machines back on to our proliants. But this is just one experience. One of our partner, wsj, seems to have good luck with ibm x-series and bad luck with proliants.
