ThunderBay 4 is highly configurable to perfectly match your performance needs. Choose between traditional hard drives or Solid State Drives. Use each drive independently, or in the RAID configuration of your choice for the optimal balance of performance and data-redundancy. Get the most out of your storage, take the brakes off your workflow, and do more with a ThunderBay 4. Certified and Tested Each ThunderBay 4 solution undergoes OWC's multi-hour drive "burn-in" performance certification procedure prior to shipping. This ensures your ThunderBay 4 arrives operating properly, ready for demanding use. 4 drive bays plus so much more. Built on OWC's time-tested enclosure cooling technology, ThunderBay 4 utilizes an open "flow-thru" vented design with an oversized 92 mm, low-turbulence, noise-quieting fan to keep the drives running cool and reliably. Daisy-chain up to six ThunderBay 4s for massive storage capabilities and increased performance, or connect multiple ThunderBay 4s to multiple Thunderbolt 3 ports to achieve exponential speed capabilities. ThunderBay 4's drive isolating design reduces sonic resonance, and is aided by over-sized, rugged, vibration-absorbing, non-skid feet.

Fairly easy setup and mac-friendly. After my Drobo 5D flaked out on me and I was unable to get ANY help from them I had to get a new raid drive for my oversized photo storage needs. So far So Good.

The construction is solid. In RAID 10 (1+0), it's fast enough to edit ProRes 422 4K video. For 6K video editing, I would suggest to use SSD drives instead of the HDD.

Bought bare enclosure (no RAID) Sept 2020 - the enclosure just failed (Oct 2024). Contacted OWC and told that warantee is only 1 yr for empty enclosures - 5yrs if HDD added. Repair also not available - outrageous given the price. I have Mediasonic enclosures that are over 10 years old and I've never had a problem with them. Buyer beware.

Previously I had an OWC Drive Dock that held 2 drives, and it had a USB connection. That one would frequently disconnect, and thus it was totally unreliable. I decided to give OWC another chance, and I purchased the ThunderBay 4. I was hoping that it would be more reliable since it uses Thunderbolt 3 rather than USB. And yes...it solved all of my connection problems! I've been using it constantly for several months with my M2 MacBook Pro and an OWC Thunderbolt Pro Dock. It's been working flawlessly. Yeah, it costs a lot more than the 2-drive USB dock, but the reliability is worth it.Pros:• 100% reliable, no disconnects• Solid metal construction. It's heavy!• Thunderbolt connection is fastCons:• I wish the drives were easier to install and remove. They are held in by screws. I'd rather have a tool-less installation similar to a Synology NAS.• I wish it was possible to close the front panel without locking it with a key. I don't need that kind of security, and now I have to worry about losing a key. Right now I'm just storing the key in the keyhole. That's fine, but I'd prefer not to have a key at all.Those are some minor gripes though. I would still highly recommend this device. I'll give it 4.5 stars, and round up to 5.

The drives seem to be working pretty well, and they are fast, but man, this thing is a little noisy when it's working. My wife came into my office, and asked what was wrong with it because it sounded like it was breaking. Plus, it has a bunch of blinking lights which can be distracting when you're trying to concentrate in a dark editing suite.

Le soft est limité à 30 jours d’utilisation. Mais une fois paramètre en RAID 5 vous pourrez supprimer l’App pour éviter d’être harcelé par le message au démarrage.
