Areca ARC-8050 8-Bay Thunderbolt to 6Gb/s SAS RAID Storage Review

 

 

In my last post I reviewed external thunderbolt storage devices for our Imac capture station, none of which worked correctly. I came across this Areca 8 bay box on the OWC website. This looked more “promising” than the Pegasus R6 :) sorry Promise Tech…had to do it. Costs around $1500/free shipping. Price is very close to the Pegasus R6 when you take into account 8 bays vs 6 bays. Its empty which is how I would prefer it anyway. Lets me use my existing drives. Here are some quick specs from Areca’s website:

  • The ARC-8050 incorporated on-board high performance dual core 800Mhz ROC storage processor and with 1GB DDR3-1333 SDRAM memory on-board to deliver true high performance hardware RAID.
  • Bootable
  • RAID level 0, 1, 1E, 3, 5, 6, 10, 30, 50, 60, Single Disk or JBOD (just a bunch of disks aka passthru)

Check out their website, they have it all spelled out. Some of the other manufacturers don’t have real detailed spec sheets showing whether they are bootable, JBOD capable, etc. Areca’s was pretty clear. The drive trays have mounting holes for 2.5″ and 3.5″ drives. Seems like a nice piece of hardware.

There were a couple of hiccups to get it going, which ended up being a default being set incorrectly. But from the first time it started up, there was a noticeable difference in operation and a feeling of reliability. The Pegasus box was just the opposite.

We’ve had it running for about two months and haven’t had any issues. In the first bay we placed a 90 GB 6G SSD OCZ Vertex 3 to run the OS (running around 400 MB/sec read & write). The next bay has a HST 4 TB Time Machine SATA drive. Next bay is empty (may use for hot spare or add another drive to the RAID 5 array). Then we have 5  2TB Hitachi SATA HD’s in a RAID 5 setup (these will be used for working still and video files, running around 415 MB / sec read & write).

I still don’t trust the RAID 5 as a single solution for storage and backup. You still need at least two other copies of all data you don’t want to lose, one of which off site at all times.

Here is the iMac machine specs we are using:

Our first attempt at RAID 5 with factory defaults and using their Quick Function > Quick Create option was not successful. The ARC – 8050 would start to initialize for an hour or so then freeze at exactly 5.6%. The box would freeze and crash the iMac. Fun. Now this product just started shipping so they will get cut some slack. The problem was also resolved quickly. See below.

Long story short, after emailing Areca’s tech support over then next couple of days and running some more tests we found a fix. Under System Configurations > Disk Write Cache Mode needs to be set to Disabled, not set to SAS and SATA (which is the default). After changing that it initialized properly the first time and haven’t had any problems since.

If you are looking for a fast external thunderbolt enclosure with all of the bells and whistles…this appears to be the ticket…for now at least.

New 27″ Imac Ordered

Should be here in about 3 weeks, will let you know how it goes. Ended up upgrading to 3.4GHz Intel Core i7 processor because it allows hyper-threading. Will upgrade RAM later through another vendor like OWC.

Will test and see if using the Apple Thunderbolt to Firewire 800 adapter will allow tethered capture with Phase One Medium Format Digital Back and Capture One 6 & 7. USB 3.0 will be nice. Still waiting for more Thunderbolt drive enclosure options.

New Imac – Christmas Comes Early – Shipping Now!

The new redesigned Imac’s are now shipping…well at least the 21.5″ models. 27″ will follow in December.

With powerful processors, USB 3.0 and Thunderbolt…the new Imac’s are decent alternatives to the aging and expensive Mac Pro towers.  I will probably hold out for the 27″ 3.2 GHz model.  I’m looking at the setup below. Will get 32GB of RAM from somewhere like OWC later. Maxing out the video card sounds like a good idea at only $150, been doing more and more video editing lately.  Go here for more info.
