Just a quick one.

Will the raspi recognise a 500 gb hdd (example only) or can it only recognise upto a certain amount of formated memory? Also, what format(s) will be recognised by the os/chip architecture?

Thank you.

Will be dependent upon the OS and drivers for USB HDDs. I would think.

Totally dependent on what format support you have in your Linux kernel. There would be no problem connecting a 500GB ext4 external USB hard drive, and for NTFS you\'d probably want ntfs-3g installed for read/write support.

I don\'t know about limitations on SD(HC) card size.

FYI, my Ubuntu 10.04-based ARM v7 (Cortex A8)-based has no issue handling both of my 3TB drives. One is ext4, the other NTFS. Both use GPT instead of MBR (which tops out at around 2TB). I don\'t see why the Pi would have any issue witth that same setup.

Things are slow though, I get 8MB/s network to ext4 HD or the other way, and 4-6 MB/s HD to HD or network to/from NTFS HD. I\'m expecing the Pi, with a weaker CPU, and shared bandwidth between all I/O (USB and Ethernet) to do much worse.

Not exactly on-topic, but what board are you using? (Just interested on what Ubuntu ARM is running successfully, being a fan of Ubuntu)

hercules eCafe, a $150 ARM netbook (512 MB, iMX 515, SDx2, USB2x3, 8GB SSD, ethernet100, Wifi.. G I think)
www.ecafe.hercules.com/
*warning* that thing does NOT like USB3 things. I started off with USB3 enclosures for my HDs, got them to run every which way with my AMD PC (disk to USK3 with USB3 cable, to USB2, swpapping cables..) and nothing at all with the eCafe, had to return the enclosures for straight USB2 ones. Bugger !

it\'s on amazon. http://www.amazon.com/s/ref=nb_sb_noss? ... fe&x=0&y=0 a bit more expensive at $200; Go for the low end model, the high-end one is the same except for more RAM and USB (oops, wrong gizmo ^^) an 8GB SD card and larger battery.

I really like the look of the ecafe after remotely playing with obarthelemy\'s pity it is out of my price range as my chinese el cheapo mipsbook is pretty much dead (and in about 50 pieces too) as it\'d be perfect for a few things i have (and want to do) that the raspi really isn\'t suitable for.

Anothrr thing came to mind. Will there be enough power to the raspi to connect and power a usb powered portable hdd? The answer may seem obvious to a lot of you, i\'m just trying to bring them all out in the open as soon as possible so all the people affraid of asking \'dumb\' questions will be in the know. Cheers guys :)!

There\'s actually a a couple threads (at least 2, possibly three) that all end up discussing this topic, go ahead and use the search feature to find them so this thread doesn\'t get hijacked (It may already be too late!) :P
