Hi,

Could anyone offer some suggestions on a dedicated raid card that supports up to 12 HDDs in Raid0?

Thanks
 
While a 12 disk RAID 0 array is not my cup of tea for any number of reasons I know the Dell PERC H710P controller will do a RAID 0 array with 12 disks in a Dell PowerEdge 720XD system.
 
wow that is a lot of drives to RAID.

I have an LSI host adapter I am pretty happy with. Maybe they have other models with more ports available? I think this one can do 8.

Curious is the RAID for speed on continuations file size? I'm a guessing you want a PciE x8 or x16 solution either way.

This one supports up to 16 devices, based on a real short read. http://www.lsi.com/products/host-bus-adapters/pages/lsi-sas-9300-16e.aspx

If you go LSI the one issue I had is the cards have two types of bios, one supports raid the other a very large number of attached drives, like 255 or something massive, but does not support raid.

The one I got came with the non-raid bios by default. Downloading the other was very easy. Getting it to flash was not. The flash program would not work with the UEFI system in this board. Ended up plugging it into an older board/system I keep to play around with that has bios.
 
Make Sure you get the LSI cables if you go this route. One end is standard sata, the other is (I belive) unique to their cards.

Mine cabe with 2 cables, each with 4 sata ports so I can do 8 drives in various raid configs or flash back to the other bios and have up to 1024 sata/sas drives with port replicators connecting them all.

I see the cards have both internal and external ports.

Any more questions about mine let me know. Though once I got the boot raid working I havent done much, need to pick up some more ssd's - read about some huge ones hitting the market - if I wont have to sell body parts to get them.

A 16i card would make more sense than a 16e.

They're standard cables, however on eBay you might easily buy the wrong ones, so personally I stick to the ones they recommend, the brand is 3Ware.

Putting 12 disks in a RAID 0 array is.... not wise.

Hopefully this is for a scratch disk for editing video files or something like that where you do not care if it fails and you loose everything because the processed data is somewhere else.

Even so... *12* disks? Assuming this is 12 relatively small disks, it would be more cost effective and better for performance to sell those off and get a smaller number of large disks. If you're using 12 large disks, then..... what. Even if using SSDs, holy cats.

The only thing I can think of would be for recording uber high bitrate HD(or higher) video. (like raw feeds from a 4k camera or something)
 
I don't know if such a camera exists but apparently 8K @ 60fps RAW 4:4:4 would give you 1,19 GB/s. Of course you'd have to connect that puppy with something like infiniband, and such a bitrate must be a nightmare to work with even with the right array of SSDs and plenty of video cards packing GBs of RAM.
