    FS UK: Areca ARC-1220 + 9x Samsung 250GB

    The drives have all sold now Asking 250 for the Areca, reasonable offers considered

    Very fast RAID 6 setup

    It just depends on how important that 600MB/sec figure is really. If its a general guide a single IOP348 or even IOP341 should do the trick, as either of them should top out in the general region of that figure with enough spindles behind them - though the only IOP341 that would do handle that many disks (that I know of) is an Areca 1280, which is getting on the cost of 2x 1680s anyway. If the 600MB/sec figure is an absolute minimum, eg frames get dropped or whatever below that figure, then you're better off going for two. Also with two controllers you would have the luxury of performance to spare in the event of changing requirements. Performance doesn't have to be an issue with 2.5" drives as the physical density of the disks (I'm talking rack space here, not platter density) is far greater. In a 2U chassis for example, you can fit 6x 3.5" disks or 24x 2.5" disks, of course the latter is going to out gun the former in any circumstance, 5400rpm or not. What is the budget for this project?

    Very fast RAID 6 setup

    You would probably need to split the load over at least two controllers to guarantee that 600MB/sec, but you can't go too far wrong with Areca 1680s with a few expanders, leaving you the choice of SAS or SATA. If they're not needing high IO performance some 3.5" 250GB+/platter SATA drives would be plenty fast, a couple 1680s with 12 drives each could nearly double that 600MB/sec figure for reads, and not far behind on writes. The only setback is the rack space that number of drives is going to need, but if that isn't a constraint then you're cruising.
  5. As title Areca ARC-1220 - PCIe 8x, 8 port IOP333 RAID5/6 controller. included is box, manual, driver disc, 8x 1m SATA cables, passive and active heatsinks. - £265 + postage (special delivery recommended) 9x Samsung Spinpoint P120 SP2504C hard disks - £25 each + postage. I would ideally like to sell these as a lot, either the card and the hdds, or just the hdds, and price considerations can be made accordingly. Happy to deliver myself within the Nottingham area, postage to UK only. reasonable offers considered Payment preferred via bank transfer or over the counter payment at a local branch
  6. like so... http://members.home.nl/rvandesanden/raid3.html I've got linux running on there now and the write speeds are far better, but still not great. Hopefully some experimenting/tweaking should get it up to where I want it. At least the bottleneck is now where it should be - with the CPU
  7. I'm using PCI, which will of course limit bandwidth, but not as much as the gigabit network it's going over. This is in a dedicated fileserver, that will do nothing other that serve media and get the occasional system image dumped to it. I'd sooner get a hardware RAID5 card and do it properly than completely replace everything in the system with a C2D setup and still have software RAID.
  8. Great stuff, I didn't realise that Windows' RAID5 was quite so bad. Throwing linux on there at the moment to see if that copes any better, failing that, looks like I may have to pick up another hardware controller (and I only sold an areca 1220 a few months ago, go figure )
  9. Yesterday I set up a fileserver running XP Pro and 6x 320GB drives in software RAID5 (2 on the onboard controller and 4 on a Promise adapter) I configured all of the disks in software RAID5 and this morning (after the 24 hour build) went to dump some stuff on it. 1-2MB/sec - This doesn't come as a huge surprise, but the odd thing is, theres no more than 3% CPU usage. I know a lot of people are pretty unhappy with windows software RAID5 performance, but it seems that that's because the CPU is getting hammered. It was my intention to have a go at it, and if its as bad as I thought it would be, wipe it and throw Ubuntu on there. Reads aren't great, around 30MB/sec and 25% cpu usage, but I wasn't expecting any more, and can't fit much more than that through my network anyway. So is this simply a case of windows RAID5 being terrible, or is something else amiss?

    I've had a dig through my box of endless bits and I've found everything that the retail pack comes with... 8x 1m SATA cables, 90deg connector on one end and a straight ClickConnect on the other passive replacement heatsink (active heatsink fitted) low profile bracket (full height fitted) manual driver/software CD pretty box

    This card is from scan, around 8 months old - The warranty period is 1 year with scan and 3 years with Areca, so either way you're covered. have a look at www.webconnexxion.com for the battery backup - £75 You could also try www.tmc-uk.com. These guys are a nice lot, sold me my first 1220 for a very reasonable price when the only other UK retailer was Insight (who wanted an arm and 2 legs at the time, and still are asking £500) There is a full height bracket on the card. 6 drives were attached to the card, so I've got 6x 1m SATA cables handy for it. Lovely card, and speedy indeed. I'm selling it because this one of two 1220s I have, but I no longer have a use for both.

    price drop to £230 inc postage, sensible offers will be considered

    We all know what an Areca 1220 is I'm sure, but anyway... PCI-E 8x, works in a good number of desktop SLI boards in the "other" graphics slot 8 Port SATAII, proper hadware RAID 128MB onboard cache, IOP333 processor Its around 6 months old, and has had light use, selling it as it hasnt really been used recently (I have another 1220 in my main system that gets used all of the time, but I'm selling all of the bits out of the spare system) Will sell and post within the UK only Cheapest I can find is £380 from www.scan.co.uk Asking £260 including royal mail special delivery via a bank transfer I have lots of positive feedback on ebay, and have been selling stuff on bit-tech forums (forums.bit-tech.net) for a long time where many can attest to my reliability if needs be.
