    Down, Down, Toshiba's are down!

    Now $138 at Umart. Rest of the players unchanged, but expect to see some follow suit soon.

    Sorry, it had to be done :)

    The Toshiba 7200rpm and WD Greens are now pretty much the same price or within a dollar or two at most shops. I know which ones I would prefer.

    Clearly the WD Greens of course? :D :lol:

    Also, here's my calculations based on 8 drives for my home system... (onboard LSI SAS/SATA chip):

    I don't think I'll be getting the 4TB drives at that price difference :wired:

    I know the Toshys have the superior warranty but wouldn't the Greens be quieter and less power consuming?

    Probably been done to death but...

    Power (idle-r/w)
    Toshiba: 5.2W-6.4W
    WD green: 5.5W-6W

    Acoustics (idle/seek)
    Toshiba: 27/28dB
    WD green: 24/29dB

    Looks pretty much the same to me, my toshibas are quiet and seem to run cool.

    Why you dividing by 2 ? (RAID1?).

    over 8 drives I'd go RAID6 instead, giving.

    3TBx8 = $1120 = 18TB RAID6 @ $62/TB useable
    4TBx8 = $2000 = 24TB RAID6 @ $83/TB useable

    RAID1 makes it look worse, as of course you're 'loosing' half the space.
    3TBx8 = $1120 = 12TB RAID1 @ $93/TB useable
    4TBx8 = $2000 = 16TB RAID1 @ $125/TB useable

    At the moment, the 4's are at the price point, that you buy them if you need the density (storage per drive/port) where the 3's won't suffice.

    If port count isn't a problem the getting the same storage with 3's. kinda evens out. e.g.

    24TB in 3's R6 is 10 drives, so $1400, still cheaper than the 4's (in only 8 drives) @ $58/TB useable (not factoring you'd probably need to spend extra to get 10 ports instead of only 8)

    The controller doesn't do RAID6, so I was dividing by 2 for RAID10 :( It's an LSI chip but a bit cut down compared to their stand alone boards.

    It's just with the ~$800 I save by losing 4TB, i could grab a bunch of SSDs as well :) I suppose long term it's not as good... but considering it's taken me this long to fill 2TB, 12TB will be massive!

    Smells like onboard raid.

    Onboard raid is fail.

    Cheaper to just replace the controller and use RAID 5/6.

    This is an ASRock X79 Extreme11 with an LSI SAS2308 controller built in to the mobo.

    I'm not blowing a few hundred on an unnecessary extra controller :-\

    What's wrong with RAID10? I've been using a 2TB RAID10 array (4 x 1TB drives - yes, it's an old array) for ages with no issues.

    Edit: It's the same chip used by this SuperMicro board: http://www.supermicro.com/products/motherboard/xeon/c600/X9DR7-LN4F-JBOD.cfm

    Ah, not exactly :lol:

    I got a pair of HP P410's from the US for $340 delivered, or about $170 each. Can do 8 drives in RAID5, or RAID6 with appropriate Cache, battery backup and HP SmartArray Advanced key.

    I've also seen some cheap Intel RAID cards on eBay also, around $140 per card. Two Mini-SAS ports, I believe they do RAID5 and possibly RAID6.

    The 4TB drives have additional value as it will be much longer before you have to upgrade your array, which to me makes up for the initial cost of the drives. Already I am seeing people upgrade there 2TB drive arrays, I myself moved from the 2TB to the 4TB drives.

    This is especially important in a device with less than 8 bays.

    I am fortunate that I have more flexibility than some here (No Wife :D ) and don't have to justify the cost of technology.

    Ok lets do a comparison.

    RAID 10
    8x 3TB = 12TB
    Cost : ~$1200 @ $150ea

    RAID 5 with RocketRAID 2720 (expandable to 8 drives)
    5x 3TB = 12TB
    Cost = $750 for HDD @ $150 ea + $220 for RAID card + cables = $970
    Or
    RAID 6 with RocketRAID 2720 (expandable to 8 drives)
    6x3TB = 12 TB
    Cost = $750 for HDD @ $150 ea + $220 for RAID card + cables = $1120

    Same storage capacity with heaps less cost. And much better performance gain.

    The 2308 is more designed as a JBOD controller for software raids since it doesnt have any kind of BBU or onboard processor/ram
    You want something like this

    http://www.supermicro.com/products/motherboard/Xeon/C600/X9DRH-7TF.cfm

    Which uses a LSI 2208 which is a dedicated processor and has 1gb ram cache, and supports all the relevant raid modes.

    The issue is that less spindles = less speed, especially if your running more then a single gigabit connection (ie 10gb or LAG connections)

    Best time to buy 4tb's is when B&H have them on sale for <200 bucks US like they did the other day, then they become economical enough to purchase.

    Different levels of redundancy. You could save even more money by going RAID0, but not everyone wants to live that close to the edge. :D

    That's a ridiculous comparison. Every example I've used has redundancy built in. RAID 0 has no redundancy. RAID 6 allows for up to 2 drives failure. How often do you get 2 drives failing within an array? If it's caused by other hardware, then RAID is not going to save you. Either way, if you're that paranoid about redundancy, perhaps a suitable backup solution should be a priority.

    I could run a RAID card... but if I was going to do that I wouldn't have got this mobo.

    Actually, if you can even find a mobo that'll run a RAID card, sound card and 4 video cards then maybe I could look in to doing it, but I'm not sacrificing video cards or my sound card for a RAID card :)

    My current RAID for example is simply running off the X79 chipset (before that it was on a few different X58 boards), and I've been happy with it for years!

    So the LSI chip is a shiny new improvement in comparison :p

    R4E can if you use single slot coolers, pciex1 for the sound card and the black pciex16 for the raid card.

    Also the MSI Big bang xpower is the same deal as its pciex16x7
