Our Verdict

What can we say? 8TB in a single NVMe SSD has a great deal of appeal for those employed with large data sets. First-class overall performance just sweetens the deal. At the clock time of this piece of writing, IT was the only game in town if you pauperism that much capacity.

Sabrent's 8TB Rocket Q caps a a couple of weeks of emotional intelligence for NVMe SSDs. It seems like exclusively yesterday when 2TB was the largest-capacity NVMe SSD, or whatsoever SSD for that thing. Actually, when I started this article it was yesterday. Now we own the 4TB OWC Aura P12, and the 8TB Rocket Q.

If you scarcely did a double-take, welcome to the club. While a bit dazed, I soldiered on and tried and true Sabrent's super-capacious beastie. Guessing how information technology mat up not having to vexation about lengthways out of space!

This review is part of PCWorld's ongoing roundup of the first SSDs. Go there for information on competing products and how we tested them.

Specs and details

The 8TB Rocket Q we tested is $1,500 from Amazon, just don't despair: Small capacities start with 500GB ($70 from AmazonTake non-merchandise link) and run through 1TB ($120 on AmazonRemove non-product link), 2TB ($250 on AmazonTake away not-product radio link), and 4TB ($720 on AmazonRemove not-product link). Yes, you pay well beyond the price of the additional NAND for the deuce big capacities. Such is life.

The Q in Rocket Q stands for QLC (Quad-Level Cell/4-bit) NAND, which is carry out its paces by a Phison E12S NVMe controller. At that place's 16GB of DRAM cache on board, and up to 25 percent of the NAND may Be employed as SLC hoard, writing entirely one bite rather than four. With the 8TB drive I tested, that's a humongous 2TB available for cache!

The Rocket Q is the standard M.2 2280 (22 mm wide, 80 mm long) form factor and is x4 PCIe 3. Note that with QLC NAND on both sides information technology may not fit into some super-thin laptops or devices.The warranty lasts for v years from the time you register the drive, and drives are rated for 120TBW for every 500GB of mental ability. Not a specially high rating, only modern break-leveling generally substance the drive should last far longer than the guarantee.

Performance

The Rocket Q delivered top-notch performance. However, that's partly because I reviewed the big dog with 8TB, meaningful that a luck of the QLC can be treated as SLC (again, 25 percent, reported to Sabrent), writing only ace bit or else of four.

A shout-outgoing to Sabrent for being exceedingly up-front about the differences in public presentation according to capacity. It's spelled come out in detail on the Rocket Q product foliate. Free burning transfers will drop significantly erst elemental cache is exhausted, and that will happen sooner in the lower capacities. However, if Sabrent is consistent crossways totally capacities with 25-percent cache, then even the 500GB model should whizz our 48GB single file write test. I did non have that ram down to tryout.

Adequate of the warnings, I had the 8TB on deal, and as you can see from the charts below, it was a bad sweet experience. (Sabrent Rocket Q is the black blockade in the next two charts.)

48gb sabrent rocket q — Sabrent's Rocket Q (Shirley Temple bar) was a bit slower reading, but faster writing that the majority of the competition listed in this chart. Shorter parallel bars are bettor.

As you can see above, while the Rocket Q didn't quite match the quickest drives reading, information technology was on point with piece of writing.

cdm 6 sabrent rocket q — CrystalDiskMark 6 rated the Sabrent Rocket Q (black bar) as fast as the competitor with 1Gb data sets.

CrystalDiskMark 6, which in our tests is set to use 1GB of data, thought highly of the Rocket IQ. Real spirit testing was just A kind in its though. What you control under is the Eruca vesicaria sativ Q setting a new record for penning a 450GB single register.

sabret rocket q4 — The Sabrent Rocket salad Q had no issues at all writing our huge 450GB single file. In fact, it set a new register of 4 transactions, 14 seconds for the transfer.

I did in the end grapple to bumper-to-bumper downcast the Rocket Q to around 700MBps while written material 900GB immediately after another 450GB file out write, with the labor about incomplete full. That's hardly a sad decline, and if the Rocket Q had had more time to sort extinct its caching the drop might not have occured. The odds of your hitting a scenario like this in real world are infinitesimal, at least until the drive gets closer to being filled. The same is true for all NVMe SSDs that pin the main TLC or QLC as SLC for their caching.

sabrent rocket q9 — Sabrent's Rocket Q finally slowed down after authorship almost 1,200GB deserving of data, but the drop, while almost 50 pct, was still not tragical. The odds of this happening to you are about zero with the 8TB model, but bequeath happen more much as you replete sprouted the drive's capacity.

With the smaller capacities, you'll see drops similar the unrivaled shown above rather, and more often. Thusly purchase the 4TB or 8TB if you can afford it.

Testing is performed on Windows 10 64-bit running on a Meat i7-5820K/Asus X99 Deluxe system with four 16GB Kingston 2666MHz DDR4 modules, a Zotac (Nvidia) GT 710 1GB x2 PCIe graphics card, and an Asmedia ASM2142 USB 3.1 Gen 2 (10Gbps) scorecard. Also connected board are a Gigabyte Gc-Alpine Bombshell 3 card and Softperfect's Ramdisk 3.4.6, which is used for the 48GB read and spell tests.

You want it if you can afford it

The Sabrent Rocket Q in its 4TB or 8TB flavors is the lug SSD dreams are made of. World Health Organization doesn't want to have their cake (carrying out), and eat out it too (capacity)? During my critical review, I found it peculiarly relaxing to slough my worry about balancing the cardinal. If you can come up the cash, you won't be disappointed.
