Sabrent Rocket XTRM-Q Thunderbolt 3 NVMe 8TB External SSD Review – Speechless

REAL WORLD FILE TRANSFER COMPARISON

For our Real World File Transfer Comparison, we have included the G-Technology G-Drive, Samsung X5 , Netstor NA611TB3,  TEKq Rapide 512GB TB3,   and Plugable TB3 2TB Portable SSD.  in our testing of the Sabrent Rocket XTRM-Q 8TB Portable SSD. This test is conducted through the transfer of data from one spot on the test drive to another to give us the truest of transfer speed results for that device.

Looking at this chart, one might initially be a bit concerned as other Thunderbolt 3 devices seem to have better performance than the Rocket XTRM Q, and that would be wrong.  None of the other SSDs shown here could possibly reach a capacity of 8TB and that is the bit of a tradeoff.  The Sabrent XTRM Q is the ONLY SSD in this chart to utilize the latest 96-layer QLC (4-bit) NAND flash memory… and the little performance trade-off for larger capacity gain just might be worth it.

REVIEW ANALYSIS AND FINAL THOUGHTS

On July 26, 2020 (or sooner), the Sabrent Rocket XTRM-Q NVMe External SSDs will become available to the public and it’s pretty easy to understand the use many will have for the 500GB, 1,2 and maybe even 4TB versions, but how about the 8TB capacity?  Who really needs 8TB of data storage in there pocket?  I do.  This is a media professionals niche item more than anything.  For my own use, I have the latest and greatest Canon EOS R5 on order and that camera is capable of 8K video, has a faster shutter speed than just about any camera on the planet, and its photographs are 45MB. That is ALOT of storage and the integrated Type-C port capable of speeds up to USB 3.2 will allow me to pull off all of that media at speeds up to 1GB/s, regardless of where I happen to be.

From there, I can later move all of that media from the Sabrent Rocket XTRM-Q to my desktop PC at speeds of up to 2.7GB/s and that has never been possible before the ..soon to be… release of the Canon R5.  First hand user application.

The Sabrent Rocket XTRM-Q will be hitting the retail market and will be the only portable SSD that we know of in the world that can hold 8TB of data in a hand-held external device.  Sabrent has built an external storage device that you could drive a tank over and it isn’t going to fail.  It feels very premium, like a solid piece of aluminum.  We even looked closely at the seems and they are so small and so exact, we can’t find any way to get inside.  It’s really built that well.   Packaging.  Check.  Build.  Check. Performance. Check. (Up to) 5-Year Warranty. Check. .19/GB for 8TB. Check.  Editor’s Choice.

    Hey Les just a quick question. Any word on when finally any drives based on the Phison E-18 will actually go to retail. Would be nice to get a drive with the potential for 7GB read and writes :}

    I think this might be one of the first external drives that uses a Titan ridge chip vs. an Alpine Ridge chip.

    Good to see someone finally using a TB3 controller in an external device that supports auto-switching between TB3 and USB3.

    Any idea how these are manufactured such that they can only be opened destructively? It’s hard to imagine that there exists no way for Sabrent to examine a faulty drive without a Dremel. (I own four of their 4TB XTRM PROs and have one of these on order for the 30th.)

      First off, I might normally chance the destruction but this product is not worth that chance. It is put together by a plate on the top but I cannot find any way to remove that plate, as it is so tightly set. It is a very fine cut. Similarly, there are no screws and the only way to get in there, IMO, would be to wedge a knife in causing visible damage. I contacted Sabrent and they stated that it cannot be opened without destroying the drive. Doesn’t really matter though as we know the drive inside…

    Does it get hot? Too hot? Which temperature? And most importantly, does it suffer Thermal Throttling? Does it reduce then the speed? How much? Thanks!

      Rather unusual question for a ThunderBolt 3 device.Gets a bit warm but nothing that merits temperature readings. I have never known any Tbt3 device to thermal throttle as it doesn’t reach anywhere near the max capability of the drive ever because of TbT 3 overhead. If you know of or have experienced TbT 3 thermal throttling, please send a link my way. I would love to see the post.

      I looked at your links and there are so many questions as to what they are doing that I don’t know where to start. What was the type of data used and how much data was pushed through before that write drop in the SSD? Did it fill? Was it being pushed into steady state which caused that? How and why did they maintain a steady transfer speed of 2000MB/s. I can’t speak to what they test but to say that your purchase should match your specific need. If you bought this SSD, what are you going to use it for that you think might push it into thermal throttling? We also have to remember that they are testing SSDs without any thermal protection on them as hthis SSD does. Much like an enclosed data center ssd, this SSD would have its heat moved to the outside of the drive where it would dissipate naturally.

        The purpose of the thermal throttling test is twofold:

        1. Worst-case scenario with 512 K sequential read or write over a relatively small area (a few GB) to prevent the SLC cache overload (if present).

        2. Performing also a Thermal Limits test, using a fixed write rate.

        Why? Just to check the thermal throttling of the SSD. Some users may be in the scenario 2, but others may be in the scenario 1, or just want to know about it. That includes large corporate orders in which SSD may be used for extreme continuous loads.

        Imagine that someone wants to fill the 8 TB external SSD with small, large o mixed files as soon as possible. Would that be possible, or would de device slow down so much as to take days, or even freeze, crash or reboot the Mac, as we have experienced with some SSD in the past? If working, how long would it take to fill the 8 TB drive?

        Devices should be tested as they are sold by manufacturers, which may include or not thermal protection. So, the only way to know if a particular SSD has thermal throttling is to test it. Both with low and extreme high load. Then, let the users decide, depending on their use and preferences. Information is good and it is great when such information shows on reviews. Choices are good. That is the reason of my question.

      I understand what the purpose is very well but there is no need as this is a portable Tbt3 device that has more than sufficient passive cooling atttached to it. The tests others have done are simply on bare SSDs. Sorry that I cannot assist any further. Trust me when i say that if there was any thermal throttling to be seen, I would have seen it in my testing. None. I have never seen such out of ANY TbT 3 SSD and this is because it is significantly lower in reads and especially writes than SSDs installed in systems.

        Thanks for the information. In our experience, most thermal throttling issues arise with external devices (and mostly with PCIe NVMe than with SATA), since internal ones usually have better cooling aids, including the complete computer enclosure. Think for instance on a MacBook or iMac aluminium body, actually working as giant heat sinks, besides the large volume and big fans inside.

        I have been talking to some SSD manufacturers these days, and they say that they do not have released such large-capacity external portable SSD yet because of such thermal throttling problems. They are thinking on doing it with SATA disks first, which are less prone to thermal throttling than PCIe NVMe, and then with the latter, once they fix the thermal throttling problems, but they are not sure that they could do it. So, it seems that there is a real technological problem here.

      It gets extraordinarily hot. I had two occasions on which to clone my MacBook Pro’s 8TB SSD to the QTRM-Q. The first occasion resulted in the failure of the drive, whose case reached temperatures as high as 171F. I bought a second XTRM-Q – which, fortunately, seems to work just fine – however case temperatures during large transfers consistently reach ~160F.

      Yes, those readings are accurate.

      Real world transfers over Thunderbolt 3 max out in the 1900s MB/s, both read and write. For comparison, the 4TB XTRM max out around 2,500 MB/s read, 2,400 MB/s write.

      DriveDx reports that the disk does not thermally throttle, and I have not found that transfer speeds are in any way related to heat…. aside from, of course, heat killing the controller. Or whatever happened with my first 8TB XTRM-Q.

      The failed drive went back to Sabrent. The exchange was accompanied by an unasked-for and surprisingly generous goodwill gesture by Sabrent, and I asked that they let me know what they find with the failed drive.

      We’ll see.

        Hi Jay – How has your experience been with the replacement they sent you? Have you had any more problems? Did they ever tell you what happened to the first drive that made it fail?

    are you sure there are no screws behind the rubber feet? Hard to imagine they would seal/weld it shut.

    hey are you sure there are no screws behind the rubber feet? So weird they would seal/weld it shut like that.
