smino Posted January 9, 2009 Share Posted January 9, 2009 Is there any way to have a raid 5 (software or Hardware) cache drive? Are any raid cards supported? I am looking for the best of both worlds! Speedy transfers with (SPOF) security. Quote Link to comment
WeeboTech Posted January 9, 2009 Share Posted January 9, 2009 Not Raid 5 via adapter card (unless you add drivers in yourself_ However, You you can have raid1 if you use an external case with a steelvine processor. I've used the AMS VENUS DS3R DS-2320SCBK with success. http://www.newegg.com/Product/Product.aspx?Item=N82E16817332006 I have not used these. http://www.newegg.com/Product/Product.aspx?Item=N82E16816215056 http://www.newegg.com/Product/Product.aspx?Item=N82E16816215068 Quote Link to comment
limetech Posted January 9, 2009 Share Posted January 9, 2009 Another idea is to attach a 2-drive port-multiplier-aware external drive case to a port-multiplier-aware controller card and use the bios of the card to set up a RAID-1. Quote Link to comment
bbrodka Posted January 9, 2009 Share Posted January 9, 2009 Take a look at this, I am considering getting it (mirrors 2 internal drives) http://cooldrives.stores.yahoo.net/inbaymosaiir.html Easy installation. No software set-up, driver set-up or hard drive partition is needed when installing in computer. When computer is switched on, hard drive back-up starts automatically, including OS & partition of System Hard Drive (or the hard drive you are going to back up). LED indicator and free software (Free Software supports Windows Vista/XP/2000, Mac & Linux) enable you to monitor hard drive and system status. When system hard drive crashes, the backup hard drive will replace and work as system hard drive automatically without putting your computer on hold. Quote Link to comment

I wonder if you could get 16 of these and mirror the whole system Quote Link to comment

I was going to use one of the addonics bridgeboards. This unit looks like you could get one of those PCI area brackets and install it all internally. Quote Link to comment
smino Posted January 11, 2009 Author Share Posted January 11, 2009 I was looking to do raid 5 for both performance and security as a cache drive. Raid 1 would not cut it. Any other options? Are there and riad 5 hardware cards supported right now? If I do a full islax nstall, will unraid recognise a software raid 5? Quote Link to comment

Are there and riad 5 hardware cards supported right now? I dunno if you can use a hardware card natively. It may be possible if you use a hardware raid card and compile in the drivers manually. There's no guarantee that unraid will see it unless you do some tweaking of the device id's and links. If that does not work, It may require the use of the steelvine processor so that it just looks like a regular drive to the BIOS. If I do a full islax nstall, will unraid recognise a software raid 5? No, the MD driver is replaced and will only work with unRAID. Why do you need raid5? Quote Link to comment
smino Posted January 12, 2009 Author Share Posted January 12, 2009 Why raid 5? I like the speed and temporary safety when transfer files to unRiad cache. Right now instead of move commands, I do copy/sync, make sure the files are off the cache drive, then delete them at the source. Takes extra time and effort. I ofter transfer 8-12GB files on a daily basis to unRaid. Quote Link to comment
smino Posted April 8, 2009 Author Share Posted April 8, 2009 I think I found an expensive alternative: If I ever have 1500$ to spare... So for the ubber rich who want the ultimate performance, use this as both Cache and Parity! Prices will come down in a few years. It will be interesting to keep an eye on this. ACARD is reasonable price for video editing! ACARD ANS-9010 150MB/s write (245$ plus ddr2 cheap ram 40$ for 4GB and up) Problem is sata2 can only go so fast! 510MB/s in raid0. But limited to 64 GB of space. http://benchmarkreviews.com/index.php?option=com_content&task=view&id=308&Itemid=60&limit=1&limitstart=11 Very cool price for 1TB of insane speed on the PCIe slot! 4GB version coming soon. OCZ 1to4TB SSD PCIE card 400-500MB/s Write sustained speeds. 1500$ to 2000$ http://www.engadget.com/2009/03/05/oczs-z-drive-puts-1tb-of-blazing-ssd-capacity-in-your-pcie-slot/ Photofast:256MB-1TB 700MB/s Write sustained: http://www.engadget.com/2009/03/26/photofast-intros-256gb-to-1tb-g-monster-pcie-ssd?icid=sphere_blogsmith_inpage_engadget 1,500,000 hours compared to 1.2 M for Enterprise class Drives (although they are exposed to heat and spinnning…) Quote Link to comment
bubbaQ Posted April 8, 2009 Share Posted April 8, 2009 New Fusion-io SSDs (PCIe bus) can hit 1.4GB/s write speeds. http://techreport.com/discussions.x/16566 Quote Link to comment
bbanks Posted November 21, 2017 Share Posted November 21, 2017 i just mount 3 ssd drives to the cache pool and run the balance option -dconvert=raid5 -mconvert=raid1 so far everything works as expected and have had no problems 1 Quote Link to comment

Sharpey212 Posted January 19, 2019 Share Posted January 19, 2019 Can you use SilverStone SST-ECS01 https://www.amazon.co.uk/dp/B00NNPKOLE/?coliid=I17W5DQF5EQCG9&colid=13QNL4KHHVIHI&psc=1 for raid 5 or 6. Is there any other way to parity on my cash drives because I do have 3 SSDs running on unraids software raid 5 i think. lol I do have pool of cash drives but i would like some sort of hardware raid so can have better error reporting.
