    Akitio AK-T3DP-T3DU3IS-AKTU reviews

    Thunder3 Duo Pro 2-Bay RAID Enclosure is rated 4.1 out of 5 by 8.
    Rated 5 out of 5 by from Brilliant Design Purchased mainly to occasionally attach random drives to a new PC, with a thunderbolt 3 connection. Had no experience with AkiTio before, but quickly admired the toolless design that is truly effortless to swap drives, yet the drives are securely mounted in a solid enclosure, and with optional fan cooling. So far just tested spinning drives, but there is no performance difference from internal Sata 6G connections.

    Rated 5 out of 5 by from Work as expected I use this with a Sager NP9873-S for editing 4k. I put 2 Toshiba 6tb with raid 0 I turn on the Akitio power, plug in the Thunder3 cable and formatted the disk and I was up and running working. Set up was a breeze, put in the HD effortless. nothing more to say.

    Rated 4 out of 5 by from I will buy another at some point. As usual, B&H purchase and delivery service is excellent. The item arrived the next afternoon. I purchased this enclosure for my new ASI Vortex gaming pc., because it has thunderbolt 3 capabilities. After installing two 2tb. hard drives, I had problems getting the drive to mount via thunderbolt or usb. I called Akitio tech support. They were very helpful. We found that the thunderbolt drivers were not up to date. I had been looking on the MSI support site for newer drivers, but failed to find them. The Akitio tech rep said he would search the MSI site and call me back or email me the drivers. About 30 minutes after hanging up on the original call, the tech rep called back and lead me through where to find the latest thunderbolt driver and firmware. I downloaded both and ran the exe. After that the drive mounted. I later ran some speed tests on the Akitio enclosure set up as raid 0. The speeds were not raid 0 speeds. I sort of think the problem is with MSI. When Macs have thunderbolt 3, I will run drive speed tests there. They will probably be better. I did not run speed tests on the enclosure as a USB 3.0 Raid 0 drive.

    Rated 4 out of 5 by from I like it, its got flaws but it works. After one day, it is fairing well. Here are my thoughts: There are 2x 1TB Samsung Evos inside the chassis. The tests I ran were on Windows 10(USB3.0) and macOS Sierra 10.12.6. On Windows 10, using usb3.0 cable/ports I barely came close to the SSDs rated speed. Check the first image, still good through out for 2160p60 but I doubt it will manage a heavy timeline. That speed was the same no matter what mode was picked on the Duo Pro chassis. RAID0/1, Span, Non-Raid, all averaged around that first image. It's because of my dated box with 3.0 ports. Fair enough. The second and third image show how copying from OS ssd to duo chassis faired. It was an 11GB file. Notice how it started super fast then just dipped towards the end to around 340MB/s. Now for macOS sierra side of things: Using the TB3 cable. Before this thing can even work on your Mac computer a few modifications have to be done. A little googling might help. How to enable unsupported Thunderbolt 3 Now I did updates on mine(MBP) from 10.12.4 to 10.12.6 this caused a particular script not to work. So I looked around github, found a different commit from 14days(From Aug 8/3/2017) ago that allowed the script to work. Fourth image shows the EVOs on SPAN(on chassis) mode, notice the drives are approaching rated speeds. 481.6MB/s -- 507.6MB/s Fifth image shows the speeds on Non-RAID mode. 484.8MB/s -- 508MB/s Sixth shows RAID1, write speeds where under but read was doubled. 341MB/s -- 694.6MB/s Seventh image shows RAID0, speeds are up for both write/read. 666.7MB/s write -- 755.7MB/s The last two images show how a copy from one Evo to another faired. Two 11GB files were sent back and forth. Speeds fluactuated around 500MB/s to 630MB/s. I did test the display port on the Duo Pro, the result was strange. If I disabled Display Port 1.2 on my 31MU97-B monitor then I got the display to mirror the MBP or Extended but it was @30Hz with scaling problems. Then I would enable DP1.2 while the monitor was mirroring the MBP, the monitor would immediately start de-rezzing, weird artifacts would appear, it would go back and forth to black then homescreen. Then there was a pop-sound coming from the monitor every 3 seconds or so. I stopped immediately with the monitor usage. Btw, you should know that the Duo Pro supports DP1.1a @60Hz but never could get it to work @60Hz. These are my observations, the benchmarks with BMD-Disk speed test are just that, benchmarks. They're not ideal for determining real world usage even though they do get very close. I'll revise the post later if needed. ^^^^^^^^ August 2 2017 ^^^^^^^^ update ****** 8/17/2017 ****** update I acquired a USB-C to USB-B 3 cable. On macOS Sierra -- Non-Raid 382MB/s Write 415MB/s Read Non-Raid TB3 483MB/s Write 505MB/s Read ---- End OS Sierra------ Windows 10 USB3 330MB/s Write 348MB/s Read USB-C via PCIe 3.1 card(USB-C to USB-B cable) 398MB/s Write 412MB/s Read. Even in RAID0, usb-c speeds did not improve at all. It's fair to say, you can still edit some 2k-4k with it.

    Rated 4 out of 5 by from Quirky, but solid and seems fast! I have an Asus X99 Deluxe II motherboard, that came with a Thunderbolt 3 card Asus makes. No documentation, nothing! And, it is not working. BUT, I think I can give a pretty solid assessment of the array, using its USB 3.1 input for now. Beautifully packaged, and REALLY well constructed. The spring loaded screws to mount the drives and release the cover are the best! Great choice. Aluminum is high quality, thick, great heat sink. I loaded in two of the new, 3.5 10GB Seagate helium packed drives. RAID 0 set on the box, nice to have hardware RAID. Windows 10 Insider beta recognized the new 20 GB disk, and it formatted easy enough. Getting about 300MB reads, and 250 MB writes via CrystalDisk. Once I get Thunderbolt 3 sorted from Asus, will probably put two Intel SSD drives in, and see if I can approach 1 GB/s via RAID 0. Having a fan toggle switch is strange. It is quiet though, my 12 core workstation makes more noise, despite being in a really quiet Phanteks beast of a case. The RAID must be set with the cover off, no idea if that is common. There is no power, on/off switch. Blue round light in front looks like one, but it ain't! All in all, really like it. Wish i could max it out though!

    Rated 5 out of 5 by from Worked as i had hoped for. I had purchased this enclosure to be able to have raid 1 capability and my computer does have two thunderbolt 3 ports. The product works very well and I am happy with the speed that it performs at. Great product.

    Rated 1 out of 5 by from T3 is the only thing that actually works on this brick! I am really steamed about this unit. When I first read about it, and all the wonderful things it could do I was excited and placed my order. The transaction process with B&H was wonderful btw. The unit arrives in beautiful packaging, but although it looks nice, this thing is HUGE. Since the only available cable at the moment is 19 long, and the unit is 9 long and 3 wide either side of the port (cable plugs in at the rear) you get about 6 or 7 of travel on your desk! Try that with a laptop. Next you have to turn the fan on manually at the back of the unit if you want to cool your drives. I since found out after extensive troubleshooting that the fan is not temperature controlled - you the human get to turn it on when you feel so inclined. Unless your fan doesn't work like mine. Next I had planned to run my Acer touchscreen external monitor (Akitio said this would work) I bought the display port to hdmi adapter as the Akitio tech support recommended, and the USB Type-C to USB adapter (for the touchscreen). With the T-3 plugged into my Asus Zenbook Pro UX501VW (either port) and the display plugged in, both my laptop and Acer monitor screens turn on and off repeatedly - sometimes they stabilize, other times they don't. Akitio tech support said they had never heard of that happening before and that I should call Acer! Since Acer doesn't service Asus and both products work fine when not plugged into the Akitio I didn't find that very helpful. Next, the touchscreen on my external monitor simply will not work when plugged into the Akitio (yes, and T3 connected to T3 for power - required for daisy-chaining or using any other ports on this unit). I tested the USB adapter independently, and then plugged a USB flash drive into the adapter and into the Akitio and it didn't get recognized either. So Type-C USB doesn't work (at least on this unit). Again, the tech support fellow told me to contact Acer! I guess Acer is responsible for the USB flash drive not working too. I never got the chance to test the USB-B connection - I have no need for that. So what I presently own is a silver shoe box that is only able to run my two 2.5 SSD successfully and nothing else. Had I have known that I would have bought a T-3 external SSD enclosure. I would be less restricted for the same cable length and have more room on my desk. I hate this thing and wish I could return it but I disposed of the packaging. Do yourself a favour and look elsewhere.
