Found this presentation where there is head to head comparision between organisation which have Lotus Notes or Microsoft Exchange deployed.
Check out SysTools Software Export Notes Migration Tool “Export Notes” which migrates Lotus Notes to Microsoft Outlook PST file.

Considering today’s requirement and availability of better hardware the question of which RAID level should be used for Domino can be answered very quickly.
Before we go ahead let’s know more about various RAID level (source: http://en.wikipedia.org/wiki/RAID)
- RAID 0 (striped disks) distributes data across several disks in a way that gives improved speed and no lost capacity, but all data on all disks will be lost if any one disk fails. Although such an array has no actual redundancy, it is customary to call it RAID 0.
- RAID 1 (mirrored settings/disks) duplicates data across every disk in the array, providing full redundancy. Two (or more) disks each store exactly the same data, at the same time, and at all times. Data is not lost as long as one disk survives. Total capacity of the array equals the capacity of the smallest disk in the array. At any given instant, the contents of each disk in the array are identical to that of every other disk in the array.
- RAID 5 (striped disks with parity) combines three or more disks in a way that protects data against loss of any one disk; the storage capacity of the array is reduced by one disk.
- RAID 6 (striped disks with dual parity) (less common) can recover from the loss of two disks.
- RAID 10 (or 1+0) uses both striping and mirroring. “01″ or “0+1″ is sometimes distinguished from “10″ or “1+0″: a striped set of mirrored subsets and a mirrored set of striped subsets are both valid, but distinct, configurations.
Considering RAID 10 is better in Write compare to RAID 5 and RAID 5 is better than RAID 10 for READ (http://weblogs.sqlteam.com/billg/archive/2007/06/18/RAID-10-vs.-RAID-5-Performance.aspx) the decision to choose should depend upon the following factors
- How much is allocated for the deployment?
- If the number of WRITES on Domino server is more than RAID 10 is recomended.
- Go with mix strategy i.e. have the Domino Data directory on higher RAID level and the program files on lower RAID level.
