OWC / Other World Computing ThunderBay 4 overview

  • 1Description

Add RAID 0 storage to your Mac or Windows computer with the ThunderBay 4 Four-Bay Thunderbolt 3 RAID 0 Enclosure from OWC / Other World Computing. As you can guess from its name, the ThunderBay 4 features dual Thunderbolt 3 ports, which utilize the USB Type-C connector. There is also a DisplayPort 1.2 port for connecting up to a 4K display. The ThunderBay 4 has four drive bays, which supports both 2.5" and 3.5" hard drives (2.5" HDDs do not need adapters). With the included SoftRAID Lite software you can format the ThunderBay 4 to RAID 1. RAID 4, 5, and 1+0 are also supported with a RAID software of your choice.

Thunderbolt 3
Thunderbolt 3 is a hardware interface that utilizes the reversible USB Type-C connector. Doubling the speed of its predecessor, Thunderbolt 3 features a maximum throughput of 40 Gb/s when used with compatible devices. The connector also transmits data via USB 3.1 at up to 10 Gb/s, and dual-bandwidth DisplayPort 1.2 allows you to connect up to two 4K displays simultaneously. Additionally, you can daisy chain up to six devices from a single Thunderbolt 3 port.
RAID & JBOD Support
The ThunderBay 4 comes pre-configured in RAID 0, but also supports RAID 1, 4, 5, and 1+0.
Time-Tested Cooling
Built on OWC's time-tested enclosure cooling technology, the Thunderbay 4 utilizes an open "flow-thru" vented design with an over-sized 92mm, low turbulence, noise-quieting fan to keep the drives running cool and reliably.
Daisy-chain up to six ThunderBay 4s for more storage capabilities and increased performance, or connect multiple ThunderBay 4s to multiple Thunderbolt 3 ports to achieve higher speed capabilities.
Vibration Dampened
The ThunderBay 4's drive isolating design reduces sonic resonance adn is aided by over-sized, rugged, vibration-absorbing, non-skid feet.
DisplayPort 1.2 Support
Dual Thunderbolt ports let you connect the display of your choice that your computer can support, including 4K displays.
OWC Thunderbolt Cable
The ThunderBay 4 comes with a 6.6' (2 m) certified OWC Thunderbolt 3 cable.

    ThunderBay 4 Four-Bay Thunderbolt 3 RAID 0 Enclosure is rated 2.4 out of 5 by 5.
    Rated 1 out of 5 by from Be careful Got this new box since i wanted to upgrade from my old thunderrbolt 2 that is still working great. on this box drives keep disconnecting. at one point 2 drives disconnected at the same time. DATA LOSS no good. worked with the software guys to see what could be done. nothing software guys are great wiling to help so looks like this is common with this box looks like i am not the first one dont buy until what ever the problem is gets fixes B&H processes my return. glad it failed within the first 30 days

    Rated 4 out of 5 by from A great high-density storage solution. Little bit too noisy! Nice and sturdy built. A high-density storage solution that replaced my 2010 Mac Pro Tower that at this point was used only for file archiving and backup. I had to upgrade the fan to cut 5dB of noise. I was able to bring it from 57dB to 52dB. Running HDs are still pretty noisy. If I'd be in OWC's shoes I would work on making it quieter.

    Rated 2 out of 5 by from Loose Thunderbolt 3 Connection I've been using the ThunderBay 4 for years and have four of the thunderbolt 2 models. This one keeps disconnecting at the slightest touch of the thunderbolt cable due to a loose thunderbolt 3 connection on the rear ports. Sadly, I'll be returning this new model. Also, although unrelated to OWC, SoftRAID cannot be used on the iMac Pro. Read the notice on the SoftRAID website for more information.

    Rated 1 out of 5 by from drives randomly disconnect This enclosure would be great except for one major problem. The drives keep disconnecting. I have 4 4tb HGST drives and they'll just randomly disconnect for no apparent reason. Unless you like having corrupted hard drives due to random disconnects while you're writing to the hard rives stay away from this garbage. Side note: OWC tech support was nice and tried to be helpful but this is beyond their ability to fix.

    Rated 4 out of 5 by from Drives Dropping Solved (at least for me) I had this problem extensively when I first bought the Thunderbay 4 enclosure. But I've since solved the problem. It now has happened only one time since then. Please bear with me while I explain how I fixed the problem. BTW no amount of searching the internet will help you. This took months of trouble shooting to figure out the solution. I have a new (2017) iMac Pro base model. I have the ThunderBay 4 enclosure and an OWC Thunderbolt 3 dock. The dock is used to add some much needed extra ports, most needed was the legacy Firewire 800 of which I have many FW800 external drives. There are two buses on the iMac Pro for the four (4) Thunderbolt ports on the back. The first two ports are on one bus, the last two are on the other bus. Being the neat freak that I am (and why I buy Apple products) I had both the TB4 enclosure and the TB3 dock connected to the last two thunderbolt ports, thus being on the same bus. You cannot do this (why, I don't know). You can check this by clicking on the About this Mac in the (black) Apple menu (top left corner) and then go to System Report. Go to Thunderbolt and you'll see Bus 1 and Bus 2, you'll see what I'm talking about. SOLUTION: You MUST have the TB4 enclosure and TB3 Dock each on it's own bus. So, connect one device to either the first two ports and the other device to one of the last two ports. Since then, I have only had a drive drop once (and that was when I had another external USB-C drive connected to the same bus as the TB4 enclosure). So I would guess this would be a problem on any Mac. Keep the TB4 Enclosure on its own bus and I'm guessing it's fine. So, at the end of the day, it's a GREAT enclosure. Compared to my other RAID drives, it's way quieter! Still some fan noise, but way more tolerable than my Sans Digital 2 bay RAID. The TB4 Enclosure sleeps and wakes with the iMac - Nice!. You do get the SoftRAID software, which is pretty nice. The only issue there is the drives do not show up in the Storage tab of the About this Mac window (my reason for only 4 stars). So you have to do a Get Info on the drive from the Finder window to see how much storage is available on the drive. Lastly, if you do have an iMac Pro, be sure to contact tech support when you set up the drive. Apple has installed some unique security settings on the iMac Pro that need changed. OWC will be happy to walk you through the fix. Everything WILL work fine. Hope that helps.
