4 out of 5 eggsGreat card - DOES NOT INCLUDE CABLES!

Pros: This card performs as advertised. Drivers are stable. Installed with no problems.

Cons: Contrary to when the specifications say "Complete kit package includes necessary cables and brackets", this does NOT include your breakout cables. It includes no cables of any kind.

5 out of 5 eggsGreat card with updated bios

Pros: The olders LSI cards had a goofy webbios that you needed to really click around alot to get anywhere.

the NEW LSI cards use the wonderful dell lsi raid bios (perc) which is awesome and you can get in and build your raid in seconds. We are definitely getting good speeds with 6 Samsung evo drives connected to this card. anyone who cries about boot up time - needs to realize this is a SERVER raid card - NOT a workstation raid card. workstations can use software raid - windows 8 and windows 2012 have excellent sata raid that is good enough for windows on the baremetal. the ONLY reason to use a hardware raid card is for vmware which requires one (until the new vsan but we are holding off on that until its a little more proven in our use scenario and bug free).

Cons: need to buy LOTS of add on's which triple the price - to get cache cade 2.0, battery backup, etc.

Other Thoughts: These cards a HUGE performance boost over the old 9271-8i cards from LSI we used to use. those are reliable as hell also - but 12gbps is key with lots of 6gbps ssd drives needing I/O.

1 out of 5 eggsWhat happened to LSI?

Pros: Um...It was easy to repackage.

Cons: * Could not initialize array
* Was not detected by Windows 7 during install, not even after providing a driver disk.
* Computer became prone to freezing up while attempting to perform device detection in the above mentioned install.
* UEFI initialization during POST took a long time while this card was installed (about a minute and a half) before the actual OS booting process could begin, but the card was evidently being skipped.

Other Thoughts: I don't like giving negative reviews. In fact I tend not to. I'll address the cons one by one. This is the second LSI card I've tried in a week. I've already replaced it with an Adaptec card and now this project is WAY over budget. I need RAID5, and I need SAS and SATA support for only 4 drives, but I'm not going to spend days or even hours troubleshooting a build of this level. This isn't a Fiber Channel SAN with multiple LUNs, this is a CAD workstation that will also see some light gaming (EVE, Skyrim, FallOut 3/NV)...a pretty straight forward build.

ASUS Rampage IV Gene (X79 chipset is the main thing here)
Samsung 840 Pro 256GB x4 (on LSI's supported hardware list)

Array initialization: Forget initializing the array, I couldn't even get into the card's BIOS to create the array. The option never came up. I kept smashing Ctrl + C (the key combo to get into the LSI RAID BIOS) like it was obsessive compulsion, hopping to make headway but could not. This is likely an ASUS implementation of UEFI, not an LSI card issue. UEFI on this mobo is real finicky about hardware. I didn't dock an egg for that, but I am mentioning it for posterity.

Windows Detection: self-explanatory. Windows simply couldn't see it. Linux could (kernel 3.8+ required in this case. Tried 2.6.38, 3.2, 3.7, 3.8, 3.10, 3.11 and 3.13), but couldn't do anything with it. But this is supposed to be a Windows-only box (at least until AutoCAD supports Linux. I'm joking, that will never happen.). No dice. I did not have this problem with the other LSI card I tried (but it also made the system unstable.) -2 eggs.

Computer instability: A lot of LSI cards have this complaint. LSI used to make great stuff. Now when I hear hardware uses an LSI chipset, I cringe and proceed with caution. I imagine when there are a group of engineers working on tightly controlled hardware for a complete system, LSI's chipsets will get the job done, but I'm still weary now. But I have no way of knowing how one piece of hardware will behave with another in a consumer context. LSI should compensate for that. -1 egg.

UEFI initialization: This computer boots in 8 seconds without this card. I expect a RAID card to make boot times increase because it will do it's own hardware checks and bring the array online. Fine, but 1 minute tops. But 1 minute, 38 seconds without an OS?! I'm subtracting the 11 seconds it takes to load a windows installation disk off my USB drive. Even High Point cards add only 20-30 seconds. -1 egg.
