The four-port LSI MegaRAID® SAS 9240-4i controller card allows small to medium business owners and gaming enthusiasts to enjoy the latest RAID 5 technology at affordable prices with low power consumption

this eight port looks good for a cheaper full featured raid card...

Hmmm....

Which is the "better" controller - the 9260-8i, the 9261-8i or the 9750-8i?

Their feature list seems to be very similar. The 9750-8i supports up to 96 devices using expanders, and 9260-8i/9261-8i "only" 32 devices. But who needs more than 32 internal devices? Other than that, there's only some (perhaps minor?) differences (SafeStore Encryption Services and hot-spare possibilities).

The 9260's have a 800mhz processor and 512MB of 800mhz of ddr2, these don't list any cache/cache speed and have a 533mhz processor.

The eight-port 3ware® SAS 9750-8i controller card provides a new level of reliability, availability, and performance to businesses that are facing storage challenges, particularly in sequential I/O intensive and multi-stream environments. This 3ware controller, great for inside-the-box connectivity, employs the latest in LSI RAID-on-Chip (ROC) technology and provides a higher standard of data protection and performance. Additionally, StreamFusion™+ can deliver breakthroughs in high-load applications and provide enhanced features and functionality in all environments.

•Eight internal SATA+SAS ports
•Two mini-SAS SFF-8087 x4 connectors
•6Gb/s throughput per port
•LSISAS2108 ROC
o 800MHz PowerPC®
•Low-profile MD2 form factor (6.6” X 2.536”)
•x8 PCI Express® 2.0 host interface
•512MB DDRII cache (800MHz)

9240 uses system ram as cache so it has no onboard cache. keeps costs low.

The number of drives the controller can "actually" support isn't representative of those numbers. Rather, those numbers are for the benefit of market segmentation from a business perspective. The controllers are all supposed to support the standard 256 devices with expanders.

FYI, that's from my 3ware/LSI FAE contact.
