Of course uptime is a concern, but it needs to be put into perspective. |
| 20 |
|
| 21 |
Let's assume that without RAID, the hard drive in use fails every 3 |
| 22 |
years and causes 24 hours of downtime with good backups. That's a |
| 23 |
loss of .09% uptime over 3 years. If the server makes $100,000/year |
| 24 |
(and the same amount every day), that's a loss of $273 over 3 years. |
| 25 |
However, my host wants $105/month for a second 15k hard drive and RAID |
| 26 |
controller card. The cost of that over 3 years is $3,780. |
| 27 |
|
| 28 |
Plus I like to keep things simple and RAID is another layer to learn, |
| 29 |
install, and maintain. Plus RAID isn't foolproof: |

Any opinions on Barcelona vs. Harpertown or 10k vs. 15k? |
