USB RAID

[Shapa10]

So after doing some more research into the benefits and drawbacks of using a RAID configuration, I've decided to start a new project.
I'm going to take a 4-port USB hub and 4 32GB flashdrives and configure 3 of them to RAID 0 and then use the fourth for redundancy (in theory).

I don't know if there is a technical name for that configuration, or if it will even work, but I'm calling it RAID 0+1.

 

If anyone has ever tried this before or has any ideas for it, please let me know!
I will update as soon as I get started on it, which might be a little while, flashdrives aren't cheap when buying multiples....

USB raid has been done before and is a great project. You could get cheap 8GB or 16GB drives.

32GB sticks will barely exceed 100MB/s, so a RAID 5 array (3 in raid + 1 redundancy is technically a 4-drive RAID 5) will not exceed 300MB/s. You may as well get a single 100+GB SSD then.

Then there's the matter of the USB hub you mention. That basically means that all the sticks would be connected to the same USB port. If it's a USB 3.0 port you'll be fine in terms of data throughput. However if it's a USB 2.0 hub or port, we're talking 15MB/s or thereabout.

Also, USB sticks typically have cheap memory chips inside, meaning they wear a lot faster than SSDs.

If you have money to spare it's a nice project. However if you want performance on the cheap, look elsewhere. If the initial cost doesn't exceed the price of a similar-sized SSD, the long-term cost will.

It's generally called RAID5 but is sub-optimal because with RAID5 you generally (not always) want powers of 2 plus one (3,5,9,etc) .

Are you using Windows or Linux? This is easily doable with ZFS in Linux or BSD. However on Windows it could be quite a challenge.

I'm runnign Windows, so I guess I'll have to tinker with it. And I'm not really doing it for long term storage, I just thought it sounded cool
speaking of sounding cool, RAID 0+1 sounds better than RAID 5 lol
