5 out of 5 eggsSpeachless

Pros: FAST!!! Supports Raid 6 & 60, Best Raid Management GUI we've ever seen. Unbelievably fast rebuild times- less than 6 hours for a failed 3TB drive on an 8 drive Raid 6 array. The BEST rebuild time we'eve ever seen for the same failure on our LSI or Areca cards is 20+ hours.

Cons: $800 for a card that supports 16 drives and Raid 60 is almost 3 times the cost ($300 vs $840) of similar HighPoint cards, which we have been running in other servers for over 2 years now. Our Highpoint cards also support Raid 6. Also these adaptect cards have looooonnnggg initialization times- we purchased 2 of these cards for new servers and it took each card more than 3 days to initialize a single Raid 60 array.

Other Thoughts: HOWEVER, to be fair I must say that we believe the other performance increases are worth the setup time. While the new array creation & initialization took 3 days, we are now getting read times 300-500% faster than ANY of our other cards... same with drive rebuilds. After installing this card I plugged (16) 3TB standard Segate Barracuda DESKTOP drives into it (not NAS or enterprise drives). I then created a single Raid 60 Array using all 16 of those drives- giving us 32TB of usable space. I then copies 31.5TB of data over to fill up the array (after waiting 3 days for it to initialize and format).

Then I pulled 4 drives out of the array at the same time. (2 from each Raid 6 set). The Array beeped, but the server continued to run without issue. I then replaced the drives, and the controller spent 10 minutes to read each one and re-add it to the Array.

I then pulled out 2 different drives (1 from each raid 6 array) and replaced them with 2 brand new formatted drives. 5.5 hours later BOTH drives had been rebuilt!! and added to the array, and the array was now marked as 'Healthy' status. The card was actually able to rebuild 2 drives at the same time- amazing.

For those who purchase this card I HIGHLY recommend purchasing the backup battery module that plugs into it:

http://www.newegg.com/Product/Product.aspx?Item=N82E16816103187

We're getting 300+mb/s write and 450+mb/s read from the Raid 60 array, mostly because we have all caching and write-back enabled on the drives and raid controller. One of the coolest things about this controller is that you can configure it to only have the cache active when the batter backup is plugged in and working. If the battery dies it disables cache to provide that additional level of data protection.

This card is AMAZING- and the only card we will be using from now on for all our server builds.

5 out of 5 eggsGreat RAID ! ! !

Pros: Fast
Easy to use GUI and BIOS
Port expander compatible
Tons of configuration options / RAID levels / informational alerts

Cons: Does not support UEFI out of the box. I had to install the card in a different machine with a plain old fashion BIOS to perform a firmware update and actually setup the RAID on the older machine before moving it all over to the newer server with a UEFI BIOS. Trying any of that in a different order led to a blank screen and no booting on the new server.

This bugger gets hot ! ! ! Make sure it has adequate airflow, better yet a dedicated slot fan.

Other Thoughts: Don't set up e-mail and SMS array messaging on anything more than the warning/error level. Otherwise you will wake up with 900+ e-mails in the morning about everything your arrays did the previous night.

5 out of 5 eggsAwesome Little Card ! ! !

Pros: It work flawlessly ! ! !
Fast throughput with no hiccups.
Pretty "Night Rider" activity lights.
Easy to use BIOS and GUI with the later having a ton of options and settings that strangely do not confuse the new guy. =P

Can be set up to e-mail/SMS on any/all faults/bad sectors/drive failures.

Cons: Hot, hot, hot ! ! !
Make sure this card has plenty of airflow as it gets rather toasty.

New guy set up the e-mail/SMS options to send on all events and went home for the day.... I had 900+ e-mails the next morning. >_<

Other Thoughts: Does not play well with UEFI style BIOS. If your server does not boot at all, you will need to flash the card on a different machine to the most recent firmware and possibly initialize the RAID there as well before installing the card and RAID in the server where you want it.
