CalDigit T3 Thunderbolt. Versatile And Fast In A Sleek Package

March 13, 20140 Comments



The need for speed is always growing. Files are getting bigger and the way to move them with the likes of Thunderbolt has made it easier. I’m a cinematographer by trade and an avid photographer with a growing library.  The next format I will be shooting with is 4K or UltraHD. These are big files so I need the fastest storage I can afford to edit in real time. To get ready I decided to purchase a 15″ Macbook Pro Retina with Thunderbolt ports. Thunderbolt has been around for a while now, but not until recently have we seen enclosures that are using it. I like to have smaller RAID’s for my laptop to use on my desk and when traveling. I have a two drive CalDigit VR RAID 0 that is performing very well to this day. The only downside is the fastest connection it has is eSATA. That was fast back when I purchased it and eSATA is still pretty fast but compared to Thunderbolt? Well….

Along comes this new CalDigit T3. A new Thunderbolt three bay enclosure. This very handsome solid enclosure comes with three drives in four different capacities starting at $450 for the 3TB model with standard HHD. 6TB, 9TB and 12TB configurations retail for $749.99, $899.99, and $1199.99. Several options are also available with SSD drives. For the fastest possible combinations you can even mix 3.5 HHD with SSD’s. Pretty flexible.  CalDigit doesn’t offer this as an empty enclosure and you will void the warranty if you replace the drives with non CalDigit purchased drives. I do wish an option was available to get this very nice enclosure empty but at this time it’s a no go.



Thunderbolt is the game changer when it comes to moving media. it’s very fast, and the CalDigit T3 is a top performer that can easily deliver 500 MB/s. The T3 comes with two ports so you can daisy chain other T3’s and other devices. I wouldn’t mind if a USB3 port was added just in case I needed to share with another computer that doesn’t have a Thunderbolt port. The T3 I have for review has three 2TB Toshiba’s

I’m all about speed so I left the T3 configured as a RAID 0. What makes the T3 unique is the ability to be configured a few different ways. RAID 0 + JBOD. This gives you speed and swappable storage in one enclosure. RAID 1 + JBOD gives you a mirrored option. Below is a video on how to configure the T3. Very simple.

As for speed the T3 delivers. Check out the speed test I did with 4K 10 bit settings in a RAID 0. 563.9 MB/s is pretty darn good.


Build Quality


The look and build is great. Very solid and is quieter than my VR since the fan is in the back of the unit as opposed to the front of the VR. The T3 has a smart fan, and in combination with the aluminum design keeps it running cool. I have been using the T3 non stop for two weeks and it just keeps humming along. The drive bays lock, and you need to use the provided key to open each bay. Dont lose the key! To release the handle on the drive bay you insert the pin in the tiny hole and the handle pops out. Pretty easy.


If you go for JBOD configuration CalDigit has archive boxes to safely store your hard drives in the drive sled. Retails for $10 each.

I like the CalDigit T3 a lot. It’s nice to look at as well as screaming fast for demanding large files. Having the extra bay is a nice touch if you want both speed and one swappable disk you have that option. With Thunderbolt the bottleneck of pushing and reading files is over until the next storage media gets even faster. I have had very good experiences with all my CalDigit products from eSATA Mac Pro cards, eSATA and Firewire express cards as well as hard drive enclosures like my VR, and the T3 is right up there in what I expect from CalDigit.

The T3 delivers but has a few cons.

  • It would have been nice if a Thunderbolt cable was included. I know they are fairly expensive still but would have been nice.
  • The ability to buy the case empty for the thrifty storage user.
  • A little longer warranty than one year since the drives are not swappable without breaking the warranty.

Pick one up at the CalDigit Store On Amazon
