Comparision

This isn't really a fair comparision for cost at all, after all Coraid's devices are SATA and Gigabit Ethernet optimized. But still it's a fun comparision to see what opensource hardware and software can get you.

15 blades no included hard drives

15 blades x 750GB = max 11.25TB

Coraid

Kurobox + Netgear Switch

Savings

Open Source Saves you $1594

Conclusion

As I said certainly not a fair comparison, the Coraid hardware is different (SATA vs PATA) and optimized from a ethernet switching standpoint vs the Kurobox/Linkstation.

But still a savings of $1600 is nothing to sneeze at!

At 1000Mb/s / 8bits/Byte / 15 kuroboxes = 8.33 MB/Sec needed in transfer rate per kurobox RAIDed together to completely soak a 1Gb/s ethernet connection. Seems like it could be doable expecially with XFS....hmmmmmmmm

My Setup

  1. USB Drive
    1. I bricked my LS when trying to mount an internal partition the first time I tried this, so I used a usb drive this time around. Which on my LinkStation was /dev/sda1 - Ramuk
  2. My Client
    1. In this case I have a PIII/600 Compaq Armada laptop running Ubuntu Dapper Drake. - Ramuk
