USB 'Psuedo Floppy' - 8GB solid state raid in an old floppy case

USB \
After looking at a similar project here, I finally figured out what to do with a handful of 2GB USB thumb drives that I had laying around, along with a $4 USB 2.0 hub I picked up along the way. The idea has been done a couple of times here, but since I was building it anyway, why not take some pictures?

The project took all of about 30 minutes and I've used it to store a 'master image' of a virtual machine that I copy whenever I want to test out a piece of shareware without risking my regular PC. I had though about actually using this to run the virtual machine on, but I didn't think the performance would be up to snuff. I had considered using a mirror configuration instead of striping so I would have multiple copies of the same data and keep critical stuff on there.... but really, anything that critical is on paper in the safety deposit box.

Anyway, without further ado, here's what I used:

4) PQI 2GB USB Sticks
1) 4 Port USB Hub
1) old 3.5" floppy drive
1) 3ft USB cable
4) rubber or felt feet (optional)

A small pair of wirecutters
A small Phillips screwdriver
Elmers (or hot melt) glue

I've added comments to the pictures, also.

Step 1Gutting the floppy drive

Gutting the floppy drive
This one is pretty simple, actually. Most drives I've played with come apart with a mixtures of screws and tabs. As you are pulling things apart, the most critical concern is not bending up the case or breaking plastic tabs. Take your time and you should get the guts out with little to no trouble. Also, remember there are lots of parts for inside that could be useful for other projects. Mother and daughter particularly liked the little copper armature inside.

The USB sticks were a little more difficult to remove from their cases. Some small, sharp wire cutters let me chew away at the plastic without destroying the insides. The next three were quick and painless once I saw how they came together.

The USB hub was the easiest of all. I knocked it from the counter by mistake and the case flew into two pieces on the floor. The only mod to the hub was the removal of a small power connector so I could push it lower into the case. Your model will most likely be different, but don't be afraid to trim as needed, as long as you don't cut any foil traces or hack through a component.

huge fan of the floppy mod. i don't think i'll use it for RAID, but i think an ubuntu mobil implementation (i.e. 3 sticks, 1 wifi) would be very handy.

Is it possible to both stripe and mirror them to get less overall capacity but more read speed?

In Windows, it's doable by using Disk Management to convert the disks into Dynamic Disks, then connecting the 4 partitions/drives to make a single one xD. Anyway, nice trick. I did that once with my two 1GB drives in Windows Vista because I had this big 1.8GB game that I had to "mobilize." If only that was native, wherein it will still act as one even without the OS..... that would RULE xD

So that won't work when you switch it in between computers?

Striping may bee faster, but if one stick is lost, all your Data is gone. There's no way to get it back. I would recomend using Raid 5. Enough speed, and if one stick ist lost, you can just exchange it, and wait for the raid to rebuild the Info of it.

If you use raid they will all register as one drive on any computer, right? Any chance of Os clashes? (windows to mac)

can i do this in windows?

Anyone know of any Raid Software that could be used?

Is there any RAID stuff 4 windows, because i have a 10-drive hub deal, but they are all E, f, g, h, i, j, k, l, m, and n.

Reminds me of the goofy CD-RW drive in my computer. Used to just write and read CD's. Now I stuck a slim-line drive in the top and underneath, a USB hub with 12 GB worth of space (2x 2GB, 2x 4GB) on it, stealthily hidden under the drive. Hub's stripped down, covered in Electrical tape, USB sticks are not. The worst part: I've had people wondering why it doesn't open all the way like a normal computer drive. I tell them, "The open door mechanism is damaged. It just pops the tray out slightly," Leads to lots of laughing.

With this idea, couldn't you also set it up to have like SD Memory used in digital cameras? Or add another hub to get 8 drives? OF is that making the floppy drive to messy?

Company called Photofast has this the CR-9000 and the CR-9100 you can use 6-8 SDHC cars up to 32bg and it connects up to Sata. 280MBs read and 200MBs write.

I'm not familiar enough with software RAID implementation, but would it be possible to have one of the drives load some kind of software RAID controller that automatically configures the other three as a single drive ?

Very nice ible

instead of gluing eject button in place, use it as an ON/OFF switch?

I would love to know what would be involved in making this a hardware raided setup. How is the RW life of thumb drives? Would such a setup (in hardware raid) be capable of running as a system drive? SSD are just still to rediculously expensive, but having nice low power non-moving drives is very nice.

nice idea

They flicker a little bit when writing, but there wasn't a practical way to bring them up front

Attack an optical fibre christmas tree or lamp with a pair of scissors :) get four lengths of fibre, hot glue onto the LEDs and route to the front of the drive? They would lose a fair bit of light being a) cheap plastic b) sharply bent, but they are only for indication not illumination so it's not such a big deal.

I have been looking for something to do with my old floppy drive, and Aldi sells 2x 2GB USB sticks for about a tenner, so this might be a plan if I can find a cheap hub.

I do indeed live in the 'burbs, but nothing so interesting at yard sales here- the only one I've seen in months was all dusty LPs, naff trinkets and threadbare curtains. I looked at everything they had and the only interesting thing was an old photo projector I considered swiping for the optics, but never got round to going back for. Maybe I'm looking in the wrong place, but people don't seem to get rid of useful "junk" around here- even the skip dipping is pretty lean. Shame.

Doh! You stole my idea! :)

Stole, or "beat you to commenting with"?

"beat me to commenting" :) I was sooo excited to have something to say! Then I saw your comment...LOL... well, back to lurking!
Aug 28, 2008. 5:56 AMcarpespasm says:
I'm thinking you could make a cool setup by removing the connectors, using jumper wires between the sticks and hub and stacking the boards to allow it to fit into an even smaller enclosure. Cool concept.

Oh mine..awesome job~ what about the performance? Does it really working well? I am kind of looking for one, otherwise I go for ramdisk
Aug 28, 2008. 3:08 PMaskvictor says:
Software RAID doesn't slow things down on modern computers. It uses such a tiny fraction of CPU power as to not be noticable; in fact some people suggest it is faster than hardware RAID (really, hardware RAID is still software RAID just on a dedicated controller, so if your main CPU+software can run the RAID algorithms faster than a dedicated controller...) Either form of RAID should speed up performance in most configurations (mirroring will speed up reading, while possibly slightly slowing writing; striping will speed up everything). I'm more curious whether the single USB cable back to the motherboard could handle the bandwidth; if the speed of each thumbdrive is more than 120MB/s then the bottleneck will be the cable - in which case individual cables back to individual USB controllers would speed things up.

Would you mind running xbench on it for some numbers? I'll bet the software raid is actually improving things a lot over just a single drive.
Aug 28, 2008. 6:20 PMJellyWoo says:
where did you get so many flash drives?
Aug 28, 2008. 5:23 PMdmm59 says:
Nice idea. You can add 4g, 8g, 16g, etc sticks as they become cheaper, for an even larger capacity drive.
Aug 27, 2008. 7:50 PMjoejoerowley says:
Neat Idea!
Aug 27, 2008. 1:57 PMdacker says:
Neat idea. I'd like to have that for my annual, "Windows is all messed-up; it's time to reinstall from scratch" (from a Ghost image.) I've never seen a $4 USB2 hub; I need to look around.... I'd suggest adding a bulleted list of materials and tools near the top.
