Flash drive raid x13, 11 second bootcharted linux

[ak47gen]

I rarely see it over 35 MB/s. But this is on 8 USB hosts. 6 cards 2 internal so 384 MB/s cap. When I created this USB 3 wasn't thought of yet.

[apanson95]

are you able to do this or use this in windows, and does it have the same speed as ssd drives?

[schmidtbag]

i'd like to see how long it takes to create a large file. i'd also like to see the flash drives blinking as things are loading, i'm intrigued by what drive does what when disks are in action

[ak47gen]

I would suspect a gig in 3 seconds with the bandwidth I got. And to let you know the blinking are random, I thought on raid 0 they would have some pattern but they seem not to go in any.

Rendering a video wouldn't be really any bit faster with usb raid. And windows doesn't support usb booting. It would be cool to do this with windows since benchmarking tools are better on them.

[schmidtbag]

windows supports usb booting, not usb software raid. as far as i'm aware, only linux and mac put flash drives, zip drives, floppy drives, etc into raid

[ak47gen]

Windows raid is call dynamic discs. In short its a crappy software raid thats very limited.  Such limitation is also using a dynamic disc for boot support and also removable devices are not supported, though you still can fake the OS and make a USB drive dynamic.

Windows doesn't support USB booting either, but you can via 3rd party software.

Install Windows on that and then render a Video in full HD :D

I would live to know in detail what hardware you're running and maybe some hdtune benchmark results? =)

[ak47gen]

Combatarms268 you will need to run linux for this to work (using MDADM or BTRFS). Also you will need mulitple usb hosts to get any good performance out of it. USB caps at 60 MB/s but almost all USB runs at 40MB/s or less.

USB2.0 is 480 Mbit, so the raw rate caps out at 48 MB/sec. Due to protocol overhead, you're unlikely to see greater than 40 MB/sec out of it. USB3.0 is 3 Gbit, so the raw rate caps out at 300 MB/sec. Due to protocol overhead, 250 MB/sec is likely the upper limit.

N1 but the kernel is verry slow..

My Archbox booting up in 11sec with sata drives (Custom Kernel etz)

[ak47gen]

Problem i have is mdadm has to be built into the kernel and intializing all 13 USB devices takes 4 seconds. I plan to try BTRFS so i don't have to use mdadm

Nice, I wish I could get mine to boot up fast like that.

+1 :o
