1 out of 5 eggsWorst RAID Card

Pros: None

Cons: Very limited support
Slow performance even with write cache enabled (30mb/s)
Runs very hot
Didn't come with cables

Other Thoughts: I bought this card in late 2014 where there were very few reviews out so I didn't know what I was getting into.

I'm running cheaper Adaptec RAID cards with better compatibility and speeds than this junk. I've updated the firmware to the latest and cannot for the life of me getting speeds over 30bm/s using either RAID 0 or RAID 5.

Beware to those considering this, stay away and don't waste your money!

2 out of 5 eggsDoes not work on boards with integrated graphics capability

Pros: Was able to re-flash the card to 9300-8i (non-raid HBA) firmware + BIOS, and now the card is recognized (earlier review said flash to 9411, which doesn't exist). Could also be flashed to 9311-8i and work. Of course it is now just a plain old HBA and have to use software raid.

Cons: Basically, any consumer level board with integrated graphics capability is incompatible with the raid firmware on this card. Since it has no on-board RAM it needs to use the same access to main memory that is taken up by the iGPU.

Other Thoughts: You have to move up to the 9361 series card if you want hardware raid, which has 1GB on board.

2 out of 5 eggsServer board only

Pros: 12Gb/s port with RAID feature

Cons: Will not work in most desktop and workstation motherboards

Other Thoughts: Tested and will not work with the following workstation motherboards with Windows 7 system:
Asus P8C WS
Asus P9X79 WS
Asus X79 Deluxe
Gigabyte X79SUP4-WIFI (this one listed as compatible as per LSI document),
Asus X79Deluxe, amount other common desktop motherboards.

These system already have LSI Raid controller installed and working (LSI 9260, LSI 9211, LSI 8704,etc...)
Install this LSI 9341 on the same slot will not work (code 10 or 12).

Install to an old Intel Server board S2000 and it works without any problem.

Some people end up flash the LSI 9341 to LSI 9411 as HBA (no RAID feature) in order to make use of it. Not sure if I will go that way.
Stay away from this controller if you intend to install to desktop motherboard.

1 out of 5 eggsAvoid this model, not a real HW RAID controller

Pros: Since it doesn't work, I can't really think of any.

Cons: Not a real HW RAID controller according to LSI support. It is fakeRAID with a heatsink. This controller is SW RAID and relies on INT15 to allocate RAM on the motherboard for cache. If your motherboard doesn't fully support this legacy function IT WILL NOT WORK.
You can create your volumes, initialize, and think everything is ready to go, but when you install the OS and driver it fails immediately.

Other Thoughts: Do not buy this card.

5 out of 5 eggsGreat card when used as designed

Pros: Excellent card, performs very well. Relatively easy to setup RAID in the BIOS, good management software.

Cons: No cables included.
SAS connection not as tight as I would like.

Other Thoughts: My experience reinforces the positive reviews. I don't think most of the negative reviews are applicable to those of us building servers. This was perfect with Windows Server 2012

1 out of 5 eggs:(

Pros: Lots of forums on how to make this piece of junk card working.

Cons: Drives don't work with windows 8. Many forums have tried to help but nothing worked for me. Some people got it fixed on theirs but my luck isn't good enough.

Other Thoughts: Stay away.

5 out of 5 eggsGreat Raid Card

Pros: I have a number of SSD's and Physical hard drives on this controller in a high end CAD/CAM workstation running windows

Cons: Cant really think of any...

Other Thoughts: A great workstation raid card (lacks BBU options as far as I can tell, so I would not use it in a critical server)

I would recommend this card to anyone wanting a high speed filesystem in a workstation or entry level server.

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.
