    Areca 1880i Noob....help!

    Do my settings look reasonable? - Look standard, nothing wrong with that What other things should I do to prepare? - not that i can think of Should I update the firmware on the Areca card? - latest is 1.49, but with the main change being added 3TB support, if you are on 1.48 I guess...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    UPS > BBU in almost all scenario. BBU can only help you restore anything thats stored in the RAID card cache. (assuming you restore power within 24hr) However, UPS will probably let you live long enough to let the RAID card finish doing any write to the drives and also gracefully shutdown the...

    Need advice on an external SAS array/case

    similar to what danny said. what you are looking for is a JBOD chassis with 16 drives and a SAS-expander. You can check out www.cineraid.com as they manufacture the JBOD chassis specifically for areca controllers and are targeted toward video editing.

    Using old "Broken" hard drive as backup drive. Bad idea?

    have u ever considered using 'used' condom? technically if they are not rip, they are still functional!!

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    You are really better off doing from scratch. The migration is probably going to take longer than file transfer. Since its an OS drive too, I'd imagine it might have some issue with migration. (migration simply clone the same image to the new RAID set/drive) This means you also need to expand...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    its common for RAID to drop as much as half of the performance when hit the 75% capacity mark. If you want more speed you can go with RAID5 instead. With RAID5 you also lose less disk space to parity (1 disk). You currently have RAID10 which kills 2 drives for parity.

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    The -12 card means you can only have 12 drives direct attached. (doesn't matter its internal or external) If you need more drives (12+), the forth port has to go through a SASexpander to get to more drives.

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    write back is general better, write-though is only better in very rare cases where all you do is sequential data transfer and the data size is identical to stripe size....etc. Basically, such condition probably only happen when all stars are lined up, LOL. After the internal ports are...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    With six 3G drives, you'll not see much improvement comparing to existing 1680. 6G performance difference only become noticable when paring 8+ SAS drives. This is one reason why Areca don't plan to release a 4 port 6G RAID controller.

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    To reflash firmware, you have to upload all four files before you do a reboot. If you reboot in between the four files, you mixed up the different firmwares. (the firmware is flashed during bootup) I recommend you do it again. (with the BBU taken off as well)

    Linux - Raid5 solution

    You can look at Areca ARC1222, here is a benchmark of RAID5 with 8 WD RE4 2TB drives running AJA benchmark (good benchmark for your video simulation) With 8 drive using software RAID and HBA, you will never achieve this kind of performance. All SATA II HBA now still only run on PCIe x4...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    There is a good chance that mainstream RAID card manufacture like Areca, LSI, adaptec won't make a internal SAS-expander. (or at least distribute under their own brand name) The main reason is they want you to buy the 24 port controller instead of going cheap by using a low port count controller...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    guys... you must realize its never just a simple performance issue when choosing a chipset. Its a complicated business decision that involves cost, performance, features, and even several legal contract issues (<< big one here) For example, a chipset manufacture (not hinting at anybody here)...
