In Controllers / RAID Cards

Flashed this card to the IR firmware, flashed all 4 of my SSD's to the most current firmware then threw them into a raid-0 array. Getting 2GB/s read and write speeds according to ATTO starting at the 128k chunk size.

FAST, does SAS 6GB/s, can use one or more SSD for cache with the CacheCade option. mature drivers and config utility. Am running a pair of Samsung 830 SSD's that are mirrored and used as cache, and 4 2TB SAS drives, and this config runs easily 2-3x in speed what my 3ware 9750-8i was getting with 4 2TB SAS drives. Makes dealing with video editing smooth and fast, OS boots up a lot faster. If I wanted, I could put several SSD's in a RAID0 as cache and it would be even faster, but my config maintains a level of safety while greatly increasing speed. The CacheVault option is good too, with that attached instead of a battery, it uses a supercap to back up its RAM onto a flash when power is removed. A supercap should in theory have a longer lifespan than a BBU.

It's fast, even a six TB array only took about 18 hours to setup fully. Easy to configure, very easy to understand with the slightest knowledge of RAID Arrays. Works in Windows 7, Also works in Ubuntu 9.04, 10.04, 11.04 and 12.04.

I needed more sata ports, and my motherboard only had 3. This allowed me to add 4 more ports, and thus 4 more hard drives. The card was recognized by windows 10, so I had no driver issues. The card worked so great that I ended up buying another card.
