The most important things I can think of to report on partitions include not only what Speccy shows now, but also some marginally more difficult ones to find:
1) Cluster size - a critical performance measure
2) Starting offset in bytes (if you want to get really fancy, tell if it's precisely aligned to some higher unit; 64KB, 128KB, 256KB, 1MB, 128MB, etc.) - another critical performance measure
Much less important but still very interesting items, primarily for RAID controllers and SAN volumes, include:
A. RAID stripe size
B. Whether the controller is in Write Back or Write Through mode
B1. Is there a BBU (battery backup unit) or other NV (non volatile) technology for protection
C. Read Ahead enabled
D. RAID level of the Raidset
E. Cache on the RAID card
