4 out of 5 eggsGreat card overall with a couple flaws

Pros: Pros
Good performance. I am currently running a 3 and 5 disk RAID5. Sequential read/write speeds scale linearly. Also handles random IO at high queue depths well (I had to crank the queue depth up pretty high, but managed to eek out over 1000IOPs on a 3 disk RAID5). Rebuilds are also quite speedy.

Massive amount of ports for the price - similarly priced controllers are in the 8 port range.

Supports flexible use of free space on disks, such as using part of a disk in one array, and the rest in another array. Also supports a 'pass-through' mode. If you plug in a drive that hasn't been initialized, it exposes it to the OS as is.

The arcconf Commmandline utility is intuitive and easy to use.

The Locate drive function can work without an SGPIO enabled backplane.

The heatsink actually has screw holes to mount a 40mm fan! I purchased a thin 40mm fan (40mm x 40mm x 10mm), and M3-.5x20mm screws from home depot. Keeps temps down - the controller reports temps around 40C. Unfortunately this protrudes into the next PCI slot’s space. Take a peek under the heatsink as you screw the fan in to make sure the screw don't go too far and hit the circuit board - if they do you'll need to add some spacers or get a shorter screw length.

Cons: Cons
maxView Storage Manager... is not a very good piece of software. I had some issues setting it up, but for now I've got it working. Once you log in and start using it, it generally works OK to view controller status, array properties, etc... until you actually DO something. Then, it starts acting inconsistently. For example, after opening properties and setting the cache mode of an array to write-through, re-opening the properties will show that the cache mode is write-back (which it isn't, I JUST set it to write-through), and you can't even set it to write-back because it thinks you didn't make any changes. Long story short, there are a lot of bugs which make maxView Storage Manager at best annoying to use, and at worst unusuable.
The only saving grace is that the arcconf CLI is easy to use and actually WORKS. In practice I start with maxView, and switch to the CLI tool when the GUI starts being difficult. The CLI also provides some functionality that isn't in maxView.

Online Capacity Expansion/Online Raid Level Migrations are dog slow. I would not recommend doing any OCE/ORLM, especially if it entails adding drives. One thing I noticed is that expansions to take up additional free space without adding/removing drives is pretty fast. However, it seems like fast OCE/ORLM is rare among high end RAID controllers.

If you enable informational events in the email notification, every day, it will send you a “Drive map” notification email for every disk.

Other Thoughts: Other
Write performance is horrible if write-back is not enabled, but that is pretty standard.
The controller’s boot initialization takes about 40 seconds for me. The BIOS management utility is not very full featured. You have to go into the OS and use maxview or arcconf if you want to do anything useful.

Verify/initialize opertaions started in BIOS management utility aren't visible to maxView or the commandline utility. However activity LEDs continue blinking, meaning the operation is still ongoing.

Has an LED light show on the back of the board for whatever reason. My guess is an engineer got bored one day...

Not recommended, but I was OK mixing SAS and SATA drives, even on the same connector.

5 out of 5 eggsGreat Card

Pros: Small form factor. Easy to install. Set up is not as complicated as some make it out to be. Card does ALL raid calculations onboard. Windows just sees a disk . Has options for just about any array possible. Maxview Storage Manager is easily navigated . Reads all smart attributes . RAID migration is easily done. Can set power saving setting for drives , arrays , and the card itself . It will email any reports to you.

Cons: Must read instruction manuals . This is not a plug and play item . Card does run warm @ ~68C . Maxview says this is normal. I am no noob . But I still read manuals. Maxview Manager must have same password as Windows. Then , every time you login , you MUST also logout . Cannot just close the window. If you do not , system has to be restarted.(This is MY observation...not in directions). I only access locally,so I cannot comment on remote access to arrays. BIOS takes ~45 seconds to load and check array status.

Other Thoughts: I have this card running a 4 SATA SSD RAID5 boot array and a 4 SAS Hard drive RAID5 storage array. Have been up over 3 months now with no errors or problems. I have the SAS drives slow down , then park , recheck in 8 hours. Also have the back-up capacitor/board installed. This thing is fast ! For writing to a RAID5 , I was worried about the temp files for ripping DVDs . With NO GPU acceleration , only compute from CPU and temp bins , I rip full movies in under 8 minutes. Windows7Pro boots in 3-4 seconds AFTER this boards' BIOS loads . This is only thing I wish I could change..BUT..it is designed to run 24/7 and the cold hard fact is my machines last longer and have fewer problems (read as:Windows errors) when I leave them always on. I use this in a HTPC/Media Server I built. So glad I paid no heed to the other two reviews here. I am happy with this purchase !

2 out of 5 eggs

Pros: When you can get it working, it works really well.

I managed to set up a 10 drive raid 5, alongside a three drive raid 0, and the speeds were as expected.

Cons: While I did not have the slow raid 5 performance mentioned in the other review, I did have several other problems.

The main problem was that their maxview storage software is absolute junk. That's what you use to configure and monitor the raid and format drives from the OS. It would only let me connect maybe 1 out of 6 tries, and I could never figure out what the pattern was for getting it working. Most of the time I had to uninstall and reinstall just to check the status of my raid, and that wouldn't always work either! This was on windows server. My only other option was to shut down the server and boot into the cards bios to check the raid, which obviously is not an option... unless you want a lot of angry employees.

After a week of fidgeting, I finally got it running good. I can't seem to get maxview to connect to it anymore, but it's been running smoothly for a few months now. I am fearful of the day that a drive fails, because who knows if I'll ever be able to log back in and fix it!

Also, the default settings for some of the raid modes are quite odd, and you really should be very very careful about going through the options even after using the wizard.

I guess the whole point of my experience is I can not trust anything this card does. I went in expecting it to take some elbow grease, being an advanced raid card, but this thing needs more work.

1 out of 5 eggsHas serious issues

Pros: Very FAST and smooth with my two OCZ Vertex 4 SSDs in RAID 0. I average 850+ MB/sec reads and over 600 MB/sec writes.

Cons: On the other hand with my five Samsung F3 HD103sj 1TB hard drives (that ARE on their compatibility list) it is completely unusable. Whether I try RAID 5 or RAID 0 mixed with 5 (through multiple logical arrays on same drive set), I get horrendous performance. I get anywhere from 30 MB/sec to 65 MB/sec READ speeds which is much less than even if I was using just 1 drive.

Furthermore apparently the Install DVD that they ship with it is defective - a problem noted by others such as a review on Am*zon. It is supposed to be bootable and give you more control over the controller's settings but it appears to not even be readable in many DVD drives such as mine and that other gentleman's.

They bill you for calling Tech support.

Other Thoughts: Updated to the latest BIOS - 30260 - dated 8/15/2013.

I'm going to have to RMA this. It certainly isn't worth the extra cost for RAID 5 capability (vs the 71605e RAID 0 capability) when it can't do RAID 5 with hard disks. I haven't yet decided to get a refund or try again with a replacement one of these.
