Sabrent has quietly released some of the best Gen3 and 4 NVMe SSDs available today, and looking through their portfolio, they too have a large array of portable solutions that we had yet to get our hands-on. So, after a quick chat, Sabrent was kind enough to send over the 2TB and 4TB capacities of their top tier XTRM Thunderbolt 3 solution, and entry-level Nano, which we will review soon.

As for the Rocket XTRM, Sabrent has designed an all-aluminum small form factor drive that takes advantage of the 40Gb/s capabilities of Thunderbolt 3. Capacity options range from 500GB on the lowest end to 1TB, 2TB, and 4TB solutions at the top. With the use of Thunderbolt 3, marketing can go wild with 2400 MB/s read and 1800 MB/s writes for the 4TB model, while the other three get a bump to 2400/2400.

Compatibility includes both Windows 10 and macOS Sierra+ machines. The MSRP of the XTRM ranges from $249.99 and $399.99 for the 500GB and 1TB solutions, while you will find the 2TB model at $649.99 and $1299.99 for the 4TB model. Warranty is set at one-year but can be bumped to two-years if you register your product within 90 days of purchase.

The packaging is equally impressive as each drive comes in a metal container with a sleeve over it.

Standing the drive, you can see the Thunderbolt logo at the top and Sabrent branding at the bottom. Dimensions come in at 4.1" tall by 1.8" wide and 0.6" thick.

Testing for the Rocket XTRM begins with CDM. Sequential performance starts with 2848 MB/s read followed by 2664 MB/s write.

ATTO shows the consistency of the drive's performance over different file sizes. As seen above, we reach peak read performance around 64K with slight variance moving up higher towards 64M.

Another test we have added to our arsenal is a 200GB file transfer to the drive. The Rocket XTRM comes in at 5.8 minutes to transfer 200GB.

Price vs. Performance puts the 4TB XTRM at 100% top in our current charts

As it sits build quality is simply amazing. The full aluminum enclosure really secures the drive and even in my attempts to open it up all were thwarted by what I assume is some legit double-sided tape.

The Thunderbolt 3 interface has enabled pretty solid performance for the XTRM and in my testing was able to hit 2848 MB/s read by 2664 MB/s write. ATTO showed stable read performance 64K through 64M with write hesitating only once around 1M. In our real-world testing, the XTRM was flawless moving 200GB of data in 5.8 minutes the quickest to date.

Pricing is quite extravagant and what's expected at this capacity. There aren't many 4TB portable SSDs running around at this point and with this form factor. For those curious, the only other option I could find was the Thunderblade from OWC that's now reached 8TB of capacity with the 4TB model coming in at $1379.99, $150 more expensive than the Rocket XTRM 4TB.
