I have 2 OWC 4-bay external drives which I run with 4 3TB drives in RAID5 mode (9TB user data). My first is about 4 years old, my second about 1.5 years old. Never had any issues with the enclosure. I had individual disk failures along the way, but I had bought "spare" drives so I would have identical drives to substitute. OWC service is good.I need more storage space and would very much appreciate to hear your views on the offerings from OWC, Raidsonic and Sonnet.
Thanks very much in advance

Thanks a lot Clark. This is very helpful. Are those enclosures also useable as JBOD? I'm asking because I've set up my Mac Pro to clone the internal drives using SuperDuper. Or does the OWC have a hardware RAID controller too?

You might want to consider IcyDock as well. I have four of them, two are my 24TB backup in RAID and two are JBODs. I think that I've had them about a year and a half now, they replaced some equally inexpensive enclosures that failed. I use these because they have eSATA ports and I have an eSATA card in my MacPro, but they also have USB-C, so they are flexible. The reason that I went the IcyDock route is that prior cases tended to overheat, and the fans on the IcyDocks and their more open design are less likely to overheat either the case or the drives. I haven't had them long enough to say definitively that they will prevent problems of overheating, but I am happy so far, knock on wood, fingers crossed.
My models have a rotating switch (screw with various position) that sets the configuration at the hardware level. Raid 0, 1 , 5, JBOD. In checking out their current web site offering, they have moved to softRAID rather than hardware settings. They explicitly support JBOD, and the starting size/set includes a softRAID lite which supports RAID 0,1. SoftRAID 5 requires you purchase the upgraded software. If you want to just run JBOD so you can SuperDuper copy other individual drives to the External enclosure, should work just fine without RAID5 upgrade. I see they also have adopted USBC connections, but typical OWC, they include a USBA to USBC cable to facilitate backward compatibility with legacy systems. When I first went to their web site, I was frustrated as all I could initially see was marketing speak. I added a system to the cart, then clicked on the item in the cart, and up popped the technical descriptions with all the detail I was looking for. I was surprised they didn't have a link directly from the web site to the tech specs, they used to.....
I have a Mac Pro 2008 and no eSATA ports. Initially I considered getting a Sonnet E2P which seems to be an inexpensive way to get it. But perhaps I should get a Thunderbolt card instead?
You can't just buy a Thunderbolt card for the cMP. The motherboard would need to support it and for those models the hardware support is not there.
Thank you Loren. I had forgotten about IcyDock, so thanks for reminding me. Any particular model you would recommend?
Here's a link to the ones that I have: https://www.newegg.com/Product/Product.aspx?Item=N82E16817198061
You will need an eSATA card if you want to go that route, but it also has USB 3.0, so that's an option as well. I found one with four ports, so I have four hooked up right now as I said.
If you have a Mac Pro 3,1, the best bang-for-the-buck external interface you can add via PCIe is going to be USB 3.1 Gen 2 (USB-C). Faster and more flexible than eSATA.
Lots of storage space in my home and home office. Plenty of SonnetTech products in my company offices, bulletproof so far (need to find wood to knock on now...). OK, I'm back. Zero experience with the other two vendors.
IMO you should consider a couple of other products, both of which I own and have had zero issues with.
For DAS, I own a few 8TB WD easystore external drives; this drive is offered in 4-8TB configurations, only available at Best Buy, but only buy the 8TB unit - the secret to these are the Red or White NAS drives inside. USB Gen 1 interface, the Red drives have a cache twice the size of that in the stock bare drive, and they're pretty much on rotating sale price around $150-$160 every few weeks or so (the bare Red or White drive alone runs around $100 more than the easystore 8TB drive. There's posts about the 8TB unit and how to tell the difference between the drives with White and Red disks inside, but you'd have to go to a B&M store and look at the SN on the bottom of the boxes - all of mine are Red drives. 16TB of Red NAS drive storage for around $300 - good luck beating that! I use Arq Desktop with these, connected to my Mini Server.
The other drive is WD's own fairly new WD My Book Duo 20TB at $800. These are intended to be DAS, but it's set up pretty much as a NAS but with a USB 3.1 Gen 1 interface and dual Red NAS drives installed. You might be tempted by the 16TB unit at $600. These are fast units with different RAID modes available. This unit was IMO one of the first WD devices like this with USB 3.1 Gen 1.
Thank you. I've read up a bit on USB-C, that would definitely be the best. Can you recommend a good card? I only have one spot left in the computer, a non-full length spot. I see Sonnet has an Allegro card with USB-C 3.1 Gen 2. Am I right that 3.1 Gen 2 is the fastest implementation on USB-C?
I need more storage space and would very much appreciate to hear your views on the offerings from OWC, Raidsonic and Sonnet.
Thanks very much in advance

I would NEVER again in a MILLION YEARS use anything from OWC. I purchased one a couple of years ago and had 4TB of data literally disappear overnight. I literally came home to the thing beeping. Tech support was absolutely useless. I even tried purchasing another OWC and moving my drives into that unit... but no luck. My data was toast. Thankfully I was able to reconstruct most everything from miscellaneous backups.
Now I use a Synology NAS. It is excellent! It even supports apps that will automatically backup your device to Amazon Glacier, S3 and other cloud services so I'll never have to worry about losing my data again. Highly recommended:

Sorry, no recommendation on a USB-C card, but even with the eSATA cards, I always went with the cheapest, and have used cards that were basically add-ins for something else I bought. Generally, it seems most of the cards use the same base chipset, so as long as you have the most recent generation card, it will work. I've never had a PCIe card for either eSATA or USB fail in either of my 3,1 or 5,1. Good luck.
[doublepost=1529479515][/doublepost]Btw I just had a reply from Raidsonic that they will soon start to sell a 4-bay enclosure from Akitio with Thunderbolt 3. I guess it is this one.I would NEVER again in a MILLION YEARS use anything from OWC. I purchased one a couple of years ago and had 4TB of data literally disappear overnight.

Thanks for the tip on the Synology NAS. Does that play well with Apple TV 3? I often stream my movies from the Mac Pro but it's a bit of a hassle to go flights of stairs to turn it on so a NAS might be what I need.
This may be a little late. But consider other manufacture like DATOptic, Areca...Thanks a lot Clark. This is very helpful. Are those enclosures also useable as JBOD?
