Introduction and Testbed Setup
Seagate's premium storage brand, LaCie, has been introducing a wide variety of Thunderbolt 2 products since late last year. We reviewed the 2big Thunderbolt 2 as well as the Rugged Thunderbolt back in July. Today, LaCie is adding one more member to their Thunderbolt family, the d2 Thunderbolt 2. The original d2 USB 3.0 Thunderbolt series was, in essence, a hard drive in an external enclosure with support for both USB 3.0 and Thunderbolt (first generation) interfaces. The product being launched today doesn't simply upgrade the Thunderbolt interface to Thunderbolt 2, but brings in some innovative updates.
One of the limitations of the original d2 USB 3.0 Thunderbolt unit was the SATA hard drive inside the unit. The new version, by default, ships with a hard drive, but also adds an SSD upgrade option (without sacrificing the hard drive's capacity play). The SSD is PCIe-based and not limited by the SATA bandwidth. The unit is, to our knowledge, the first external hybrid desktop storage drive. As we will see in the performance section, it also happens to be the fastest single-drive desktop storage system. On the external side of things, the new unit also has a slightly different industrial design. The detailed specifications of the review unit are provided in the table below.

Testbed Setup and Testing Methodology
Evaluation of DAS units on Windows is done with the testbed outlined in the table below. For devices with USB 3.0 connections (such as the My Book Duo that we are considering today), we utilize the USB 3.0 port directly hanging off the PCH.
|AnandTech DAS Testbed Configuration|
|Motherboard||Asus Z97-PRO Wi-Fi ac ATX|
|CPU||Intel Core i7-4790|
Corsair Vengeance Pro CMY32GX3M4A2133C11
32 GB (4x 8GB)
DDR3-2133 @ 11-11-11-27
|OS Drive||Seagate 600 Pro 400 GB|
|Optical Drive||Asus BW-16D1HT 16x Blu-ray Write (w/ M-Disc Support)|
|Add-on Card||Asus Thunderbolt EX II|
|Chassis||Corsair Air 540|
|PSU||Corsair AX760i 760 W|
|OS||Windows 8.1 Pro|
|Thanks to Asus and Corsair for the build components|

vFunct - Wednesday, September 10, 2014 - linkDrobo also has an external hybrid HD/SSD storage system.
m2inor - Friday, September 12, 2014 - linkDrobo uses mSATA. LaCie is using PCIe SSD for much faster I/O.
simonrichter - Friday, October 3, 2014 - linkYou are right, and also LaCie doesn't match up to some of the really good computer storage devices (see http://www.consumertop.com/best-computer-storage-g... for example).
sheh - Thursday, September 25, 2014 - linkI think USB 3.1's Alternate Modes pretty much dooms Thunderbolt.
tricktech - Wednesday, October 1, 2014 - linkInterested to know when you get an update on the CRC errors and temperature - on the hook waiting to buy one of these drives.
hketterle - Wednesday, October 8, 2014 - linkAnandtech, please review external Thunderbolt devices with a Mac system as well. The past three reviews (2Big Thunderbolt 2, Promise M4, and now the d2 Thunderbolt 2) have all been reviewed on a Windows test rig. First off most Thunderbolt users today are likely to be on Mac systems as Thunderbolt is built into all Macs of the last 3 years. Secondly, I don't think this gives particularly accurate results. The main result I call into question is the R/W speeds of the 2Big Thunderbolt 2. These are much lower than Lacie's claims, and slower than the previous version despite using higher density drives (at least on the 12TB model). It seems likely that there is a performance bottleneck in the Thunderbolt adapter or software your test rig uses.
I really loved your earlier reviews of Thunderbolt external storage (like Anand's review with the Thunderbolt display sound issues) and would like to see your site keep up the high standard of technical review. I think this would require testing Thunderbolt with a Mac system as well.
hketterle - Wednesday, October 8, 2014 - linkhaha, would have been good to read the whole review before posting. Thanks for the effort to test with a Mac too
fredzer - Wednesday, November 26, 2014 - linkIt is much cheaper to just remove the HDD from the unit and replace it with an SSD, without buying the LaCie upgrade kit. That way, you get lots more storage (up to 1TB SSDs are available). I did this with a Crucial SSD, and it works just fine. Speeds top out in benchmarks at about 450 MB/sec, but that's probably due to the fact that my SSD is over a year old.
sagesupport - Friday, October 12, 2018 - linkHey, This is a great article. I was searching for the same and I found the best content here. Thanks for sharing the info. keep on doing the great work. https://livetechsupport.org/sage-one-support/
