5 out of 5 eggsIt's a full-height card!

Pros: Assuming it's like my other Areca cards this will rock. Get the BBU so you can safely use the cache for writes and you'll have one screaming setup

Cons: Not a "con" really, and not the fault of the card, just the fault of the idiot that bought it (me)! But this is a full-height card, doesn't fit too well in a 2U case. :-) Make sure you have the room for it, or the ability to mount cards horizontally w/a riser card.

4 out of 5 eggsRAID 6 - 11TB

Pros: I chose next day shipping. Running 8 Seagate Constellation ES.2 ST32000645NS 2TB in RAID 6 on this card - just because I can. As you can expect, Windows 7 x64 takes some time to look at a drive this large during boot and Disk Management.

Array access is quick under normal file transfers and network access.

Cons: Price. However, you get what you pay for.

Other Thoughts: Internet port is awesome to manage the card remotely.

5 out of 5 eggsSolid as a rock

Pros: I have had this running in my server for over 2 years now. I have 5 1TB drives running in a RAID 5 spanned across 2 partitions (OS and Storage). I have put all my important data on here and am amazed at the speed!

For those having issues installing in Windows 7 (32 or 64 bit) there are new drivers out there. This includes Server 2008 drivers as well, as that's what this is running in at home.

The HTTP proxy interface rocks as well - I can see the status of my array from any computer in my home, and even online if I set up my firewall and port forwarding correctly on my home network.

I set up a RAID 0 on a separate Array on this card, just to test Write speeds to the Raid 5. (I wanted to maximize read speeds from the RAID 0 to eliminate what bottlenecks I could from the drives themselves). I reached 700-800MB WRITE speeds. Insane. Copying a 3gb ISO file took, what, like 5 seconds? Anything smaller and I don't even see the windows file transfer dialog box. Awesome.

Cons: If you've never done RAID before, I suggest you read up a bit beforehand. If you don't know what you're doing, you'll probably configure it incorrectly, if you get it working at all.

Other Thoughts: Get the battery, or at least have (and be confident in) a serious UPS solution. If you invest the money in something like this, you are serious about your data. Be serious as well about your redundancy and support of the hardware environment you put it on.

You know it's fast when 700MB movie files transfer just as fast as word documents do on your laptopl, lol!!!

5 out of 5 eggsARECA= AWESOME

Pros: I bought this card back in 2007 and it has worked flawlessly in every motherboard I have put it in without a hiccup.
The Card is a Stellar Performer and you will not beat the Bios Options and config options Areca Provides on their controllers period

Cons: None in 4 years of owning it!

Other Thoughts: If you are a overclocker and change boards allot then the ARECA brand is what you want. I have had this card in Primarily D.F.I Boards but also aBIT EVGA ASUS as well

5 out of 5 eggsAbsolutely awesome RAID!

Pros: The built-in Web server is amazing; simple, effective, and very easy to use; much easier than the front panel LCD screen (ARC-1000), and it can be used realtime while your system is running.

Neat trick: Pass one of the SATA expanders out the back of your case, along with one SATA power cord. Have either standalone drives, or drives in a 4:3 cage (4 3.5" drives in a cage that fits into 3 5.25" bays, like the COOLER MASTER STB-3T4-E3-GP 4-in-3 Device Module Hardisk Cage). Mount SATA power Y cables to the drives, so there's only one plug. In the cage, add the power supply for the cage's fan with another Y cable. Plug in your one power cable, and four SATA data cables to the drives; any order, the controller reads data on the drives to see what they are. Set them up as passthrough (individual drives) if you like, or as a raidgroup. Have your OS rescan the SCSI bus (Debian:, Google it).

Cons: Out of respect for other reviewers noting heat issues, I rubberbanded and cable-tied a quiet, low speed 40mm fan to the heatsink, and plugged it into the card. I've never once had a heat related alarm.

Does work wonderfully on a GIGABYTE GA-890GPA-UD3H, just doens't boot.

Other Thoughts: NOTE: I've had issues with the rescan not seeing a new LUN on an existing bus and ID in Debian Squeeze (testing); just assign another ID instead. On the Volume screen of the Web interface (remember, the card itself has an Ethernet jack), instead of, say 0:0:3 (0th bus, 0th ID, 3rd LUN), select 0:1:0 and rescan the buss.
Works fine with a GIGABYTE GA-890GPA-UD3H rev 2.0 for drives; _except_ that I was unable to boot from the RAID card. Solved by putting a regular SATA boot drive in, and regularing drive imaging that to an NTFS RAID volume (Acronis Trueimage sees the RAID volumes just fine).

I've done both live Raidset expansions (3 to 4 drives), and live VolumeSet raid level migrations; no issues in either case. Good performance throughout; it just takes a long time for 2TB Volumesets to be checked.

SCHEDULE YOUR VOLUME CONSISTENCY CHECKS! I've seen an HP NAS lose over most of its data because after one drive in a RAID5 actually failed; another drive revealed it was corrupt.

5 out of 5 eggscheap virtual storage pool

Pros: - Good warranty and tech support
- Firmware is actively developed
- Seems to be especially good at dealing with older SSDs

Other than that, the benefits are mainly related to the big cache:

- your system maintains QoS with fully committed physical memory
- cached reads can saturate the PCIe link; writes can come close
- build small shared storage with decent performance using inexpensive disks

Cons: - should include battery module, because you need it anyway
- for desktop use, it would be better if one of the SFF connectors were external

Other Thoughts: I use this card in servers and technical desktops. It's a good price/performance point for me, and having done lots of embedded and systems programming I'm always impressed at how well-tuned the Areca disk scheduler is. This card can wring more IOPS out of an ordinary desktop drive than any other I've seen.

5 out of 5 eggsAreca 1231

Pros: Easy to configure, 12 channals, Win 7 64 drivers, SNMP capability, ethernet port for management when on-line, and finally, this card is fast, almost 2 GBs throughput in Raid 6...!

Cons: Bad boy runs hot. Alarm comes on at 70C. Installed small fan, now runs at 46C.

Other Thoughts: Easy to install, can be set up as 'boot' drive in Win 7 64, I have in Asus P6T6 WS Mobo. Don't forget to order a small fan for it.

1 out of 5 eggsTotal waste of money

Pros: It worked for a few months, but not reliably.

Cons: Areca makes horrible products and doesn't support them. Card worked for a few months, then died. RMA'd the unit, when I received it back all they had done was reinstall firmware (their own admission). Spent a considerable amount of time and money swapping out other parts to satisfy their phone support reps. Months gone by with no reply on support requests, no reply to phone messages.

I now have 4Tb of data that I cannot access easily, and flushed ~$2k down the drain for new mobo/CPU/Mem & power supply. I expect better support for this kind of product, as is Areca products are a liability in any kind of mission critical situation.

Other Thoughts: If you need a RAID card, don't buy it from Areca! I did not purchase this from Newegg, wish I had!

5 out of 5 eggsGreat Controller - Some Driver Issues With Windows 7 Pro x64

Pros: Amazingly fast! Makes my 2 OCZ Vertex Limited Editions work faster then on my motherboard's Intel ICH10R!

I'm running 6 drives running in 3 different Raid0 arrays (2 drives per array) on this single card!

WEI score of 7.9 (max).

The 2 GB of cashe works great!

Cons: It took about 3 hours to figure out how to use it in Windows 7 Pro. From what I can see, there is no way to add it to this card an existing install. So I did a clean install.

I tried tons of different drivers including the one I ended up with, and they gave me error code: areca error 0x80300001. I'm not sure how the driver ended up working... but it does....

It runs hot at 64c, I have extra room so I think I'll add a fan.

Other Thoughts: I copied driver version: arcs64_V6.20.00.19_91126_W7WHQL to a memory stick and used it while installing.

I live in a remote area where the power goes out all the time so I spent extra for the battery backup. I only hope my power comes back on within 48 hours :).

While this is a server grade product I purchased it for gaming which it works great at.

If you have a ton of hard drives you want to run in raid, or want the maximum performance from your drives, I highly recommend this card despite the price!

Windows 7 Pro x64.
eVGA x58 4-way MOBO
2 x 100GB OCZ Vertex Limited Edition SSDs
2 x 600GB WD VelociRaptor (released spring 2010)

5 out of 5 eggsWonderful raid card

Pros: Very very fast card. I replaced it with a 1210 card which could only support 4 drives. The 1210 card was fast enough but this card is in it's own class. With 4 Velociraptors running in RAID 0 my bursts reads went from 600mpbs on the 1210 to over 1000mpbs. My sustained read didnt improve much but then again we are limited to the drive's specs. The sustained reads went from 400mpbs to 420mpbs.

Cons: Very loud beep during startup

Other Thoughts: If you have some SSD's or high quality drives such as the velociraptors I recommend this card. It utilizes your hardware 100% and if you are going to pay a pretty penny for the drive you might as well go all out
