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
- SATA Storage - SR1520
- Total: $3996
Kurobox + Netgear Switch
- 15 Kuro Box HG WR vblades
- 15 x $149 each = $2235
- NETGEAR GS116 16-port Gigabit Switch 10/100/1000 Mbps
- $167
- Total:$2402
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
- USB Drive
- 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
- My Client
- In this case I have a PIII/600 Compaq Armada laptop running Ubuntu Dapper Drake. - Ramuk
Transfer speeds
- Very interesting indeed. Mounting a 20 GB USB 2.0 External Drive over a 100baseT switch using the StarPort software from Rocket Division Software on a Windows XP computer I was able to get a sustained 4 Megabyte/sec or 32 MB/s transfer rate..... not too bad. I'll have to try it with a EXT3 block device and a Unix computer. Ramuk 01:36, 29 August 2006 (EDT)
