SABRENT Rocket XTRM 5 2TB Thunderbolt 5 Portable SSD, 80Gbps Connection, Up to 64Gbps Transfer, Compatible with TB4 TB3 USB4 USB 3.2 20Gbps 10Gbps 5Gbps, Rugged Aluminum and Silicone (SB-XTM5-2TB)

I feel like I've unlocked a rarified nerd achievement in being the first customer to leave a review of this brand new external ssd from Sabrent, the Rocket XTRM 5. The 5 in its product name obviously being indicative of Thunderbolt 5. I purchased the 4TB model and at the time of writing it is still only up for preorder on Sabrent's web site, which is pretty wild. Amazon not only came through with stocking the product but also a killer price for Prime Day. It was almost too good to be true! While it may be a bit daft to post a five star review the day of receiving this product, I have no reason to doubt its longevity. I've had multiple Sabrent drives from this same range, in smaller disk capacities, back in the days of the Thunderbolt 3-spec and they never gave me any problem. This updated Thunderbolt 5 iteration stays true to Sabrent's "Rocket XTRM" product/design language. It remains very small and comes with a most-appreciated silicone jacket. This not only helps with physical protection and bumps, or I suppose if you were to drop the drive from a short distance, but moreover it keeps the drive less hot to the touch. Without the silicone jacket it absolutely gets pretty hot. My other drives have always also been like this, so it comes with the territory. The included TB5 cable is also a nice length (right around 19"). It isn't too short like I've seen other drives come supplied with. If anything, I wish it was shorter! Now, for the fun part. The speed tests. As you can see from my screenshots, yes, the drive is blazing fast. It is faster than any external drive that I have ever used by a large margin. I included a screenshot of its performance in "Blackmagic Disk Speed Test" as well as "Magic Disk Benchmark." These were all on a MacBook Pro 16" with an M4 Max processor and Mac OS 15.5. Since this current model MacBook Pro is Thunderbolt 5-equipped, you are able to take maximum advantage of the ssd performance (and why else would you purchase it, if you do not have a TB5 host computer? Unless you were "future proofing..."). In one of the tests, you can see that it reported that the read speeds were actually faster than the internal ssd of the computer itself. Regardless of it being able to potentially rival the speed of your internal ssd, it handily trounced my other external ssd I've been using over the past year, which is the Thunderbolt 3-spec SanDisk Professional PRO-G40, which is also in a 4TB capacity. Based on the tests you can see in the screenshots, it isn't terribly far off from being twice as fast in both read and write speeds. Depending on what you use your computer for, that level of a speed upgrade may justify the admittedly hefty pricetag. It kind of blows my mind to think that an external drive could sustain read and write speeds of four to five gigabytes per second, but here we are! If you're looking for what is certainly among the top tier of the fastest external drives that you can pop out of a box and connect to your computer, no need for assembling your own storage and enclosure, this is it. I will revise my review if I end up having some debacle in the future, but for now this is a most impressive addition to my home+work setup (I'm a creative professional). Of note, on Sabrent's web site you can register the drive to extend your warranty from one year up to three years. *** UPDATE *** Four months after my initial review (that I wrote at a time when the product had just launched) and thankfully I have nothing but positive things to say about it. Zero issues with it ejecting itself. I work from the latest versions of Mac OS — maybe if users are having problems with it, then they are on different operating systems and, thus, using it with a different file storage format instead of encrypted APFS. I’ve been using the drive nearly every day and it hasn’t given me any issues whatsoever. For someone who is constantly working with massive Photoshop files and then having them render within a litany of InDesign documents, this drive is par excellence. We’re talking editing and saving files that are often easily 1gb+ in size and you can just blaze through your workloads with minimal wait time. I suppose that you could complain, yes, it gets very hot to the touch (less so if you hold it by the included silicone jacket), but all of my other external Thunderbolt ssd units, which aren’t even close to being as fast, have been similarly hot to the touch. Of note, I was very lucky and snagged one of these during some special sale or Prime Day event, knocking $200 off. It was still expensive. As they say, you get what you pay for.

Expensive, yes! Unbelievably high speeds, yes! Well made, yes. Small and light, yes. Very functional. Very impressive! Heats up when transferring 200+ gigs at a time. Worth every penny. Very pleased.

Using this as an external drive for video editing with Final Cut Pro v11 on my MacBook Pro M4 Max. MacBook saw it and I formatted it and it works as expected. Thunderbolt 5 is the fastest protocol you can get and this drive hits advertised speeds. Should be perfect for my work. Sabrent has a solid reputation for its external drives, which is why I chose this over other drives. You must have a Thunderbolt 5 rated cable to get the most out of this and a short one is provided with the drive.

My first drive kept disconnecting from my MacBook. I returned it and got another. This one also kept disconnecting. I reached out to sabrent and they suggested a new cable. I tried that and it seems so far to have done the job. The drive itself delivers on its promise. Fast. I wish they made an 8tb. Edit: unfortunately the disconnects have returned. I don’t think this will work out.

I will give it a 5 star for very fast speed, around 4500 MB/sec. HOWEVER, and you want to read this important part. Say you are transferring 3 TB a data from one fast SSD to this SSD it starts off fast and then the speed drops off tremendously as the hard drive heats up. So don't expect that crazy speed to continue I will probably remove the rubber bumper case it came with as this thing is just going to be sitting on the back of my desktop computer without needing to me moved. Thermal gun was reading about 130 degrees. You might want to refrain from transferring over a terrabyte of data in one shot and give the disk time to cool. It's day 1 of using it, That's all I have for now. The only issue with it heating up is the fact that it slows down A LOT.

Fast is an understatement! If you have TB5 on your machine and are looking to expand your storage, this 4TB external drive is incredible. I can’t comment on “longevity” because I’ve only had it about a month but… wow, amazing sustained read & write speeds that rival the internals of my M4 Max 4TB Studio. It is small and the rubberized coating prevents it my sliding around the desk. It does get warm but that is expected and therefore I don’t place it on top of the Studio itself. I will update if anything changes but for now, I am confident recommending it to those with TB5 connectivity.

Awesome and so fast! Instant backups and very compact! I love it!

UPDATe: After about 90 days of use, I returned the replacement unit for the same reason—incessant spontaneous disk ejections, no matter whether the MacbookPro was plugged in or on battery. The rest of the review remains accurate. This SSD delivers on speed but with a hiccup. Perhaps five times per day, the first unit I ordered ejected itself spontaneously, and for no apparent reason, even when it and the MacBook Pro to which the SSD was connected were both physically idle. In short order, I requested and received a replacement unit that differed from the original in one respect: the T5 cable included with the SSD was now detachable. The spontaneous ejections stopped, and I plan to keep this replacement. Compared with the OCR Envoy Ultra, the Sabrent is substantially smaller, lighter, and more portable—important if mobility matters. Update 1: the incessant spontaneous disk-ejection problem has returned. Even if the hard disk is plugged in idle on my desk, it spontaneously ejects. This is the second out of two units I've ordered that have this problem. I'm going to contact Sabrent about a replacement and will post the results of my experience with them.

Great product if one need a fast thunderbolt drive for creating local backups. It's compact and it doesn't take a lot of space.
