Sabrent Rocket 4 Plus review


The Sabrent Rocket 4 Plus (from $89.99 for 500GB; $1,499.99 for 8TB as tested) combines good speed and durability with massive capacity in an internal solid-state drive. Its overall storage and gaming test scores were low compared to other PCI Express 4.0 SSDs we tested, but to be fair, none of the PCIe 4.0 models had more than a quarter of the storage space of the Sabrent. If you want colossal capacity with decent performance, the Rocket 4 Plus is one of the few games in town; the few other 8TB M.2 drives we saw were all PCIe 3.0 models.

All the storage you can get, all from one location

The Rocket 4 Plus is a four-lane PCIe 4.0 drive built on an M.2 Type-2280 “gumstick” PCB (80mm long). It uses the NVMe 1.3 protocol on the PCIe 4.0 bus. It comes with a Toshiba BiCS5 3D TLC 112-layer NAND flash, 2x 8GB SK Hynix DRAM and a Phison PS5018-E18 controller. (Check out our glossary of SSD terms if this jargon is new to you.)

Our test unit came with an optional heatsink(Opens in a new window) ($25), a large copper/aluminum unit designed for use in desktop computers and pictured below. Sabrent also sells a much thinner radiator(Opens in a new window) designed for use with a Sony PlayStation 5, but you should note that the PS5’s maximum secondary storage(Opens in a new window) the capacity is 4TB, so while smaller capacity Rocket 4 Plus SSDs will work, our 8TB model won’t.

The table below lists the capacity, price, durability, and rated throughput of the different versions of the Rocket 4 Plus. While the first four versions use Micron B47R 3D 176-layer NAND flash memory, the 8TB drive sticks to the BiCS5 112-layer NAND mentioned above due to space considerations on the actual PCB, according to Sabrent. .

You can see that, in terms of value, the Rocket 4 Plus’ sweet spot is 2TB, costing just 10 cents per gigabyte. From there, higher and lower capacity versions get progressively more expensive. As is usually the case with SSDs, huge capacity is a luxury for which you pay extra per gigabyte. It’s only the second 8TB SSD we’ve ever tested after the Sabrent Rocket Q, a PCI Express 3.0 device with QLC-based memory.

The Rocket 4 Plus uses longer-lasting TLC memory, as evidenced by its “terabytes written” (TBW) spec, the manufacturer’s estimate of how much data can be written to a drive before certain cells begin to fail. breakdown and are taken out of service. The 5,600TB rating of our test unit is considerably better than the 1,800TB rating of the 8TB Rocket Q.

Sabrent officially warrants the Rocket 4 Plus for five years (or until you reach the rated TBW figure in data writes, whichever comes first), but you must register with the company to get the full warranty. (Unrecorded discs are only backed up for two years.) Sabrent sells the disc through Amazon as well as on its own site.

Rocket 4 Plus review: some solid speeds

We test PCI Express 4.0 internal SSDs using a desktop test bench with an MSI X570 motherboard and AMD Ryzen processor, 16GB of Corsair Dominator DDR4 3600MHz memory, and a discrete graphics card .

We ran the 8TB Rocket 4 Plus through our usual internal SSD benchmarks, including Crystal DiskMark 6.0 and PCMark 10 Storage. We’re also including results from a relatively new test, UL’s 3DMark Storage Benchmark, which measures a drive’s performance in a number of gaming-related tasks.

Let’s start with Crystal DiskMark’s sequential speed tests, which provide a traditional measure of drive throughput, simulating at best straight-line transfers of large files…

While the Rocket 4 Plus effectively matched its rated sequential write speed, its sequential read speed was a bit short. Still, the drive takes its place in the middle of the pack of PCI Express 4.0 NVMe speedsters, the only 8TB device so far in our top tier.

The PCMark 10 Overall Storage Test measures a disk’s speed in performing a variety of everyday storage tasks, while the so-called PCMark 10 Trace Results measure its mettle for specific tasks such as booting the operating system, loading creative apps and games, and copying small and large files.

The Rocket 4 Plus landed in the bottom third of our comparison group in PCMark 10, and its trace results were also generally unremarkable. It achieved the second highest score by copying large ISO files. His 3DMark game score was at the bottom of the group.

The verdict: so fast, so big? It will cost you

As one of the only 8TB general-purpose internal SSDs available, Sabrent’s Rocket 4 Plus offers cavernous capacity and throughput speeds worthy of a high-performance PCIe 4.0 drive. Its general and gaming benchmark results were weak compared to similar (but smaller capacity) drives, though it was significantly faster than the only other 8TB M.2 SSD we tested, its stablemate Rocket Q.

Although the 8TB drive exceeds Sony’s upper limit for secondary SSDs for the PlayStation 5, one of the smaller Rocket 4 Plus models should be used with a PS5. Because the 8TB version uses 112-layer TLC NAND rather than the 176-layer Micron B47R NAND of its siblings, the 2TB and 4TB drives have significantly faster write speeds, and the 2TB Rocket 4 Plus is barely half the price per – gigabyte basis.

Still, if you’ve got the cash, the 8TB Rocket 4 Plus gives you monumental storage capacity and PCI Express 4.0 speed in a durable internal SSD, if you only have one PCIe 4.0 slot that you can fill. It’s a great addition for a games or media library with room for most anything you might want to store.


  • Huge capacity options (up to 8TB)

  • In testing, matches Sabrent’s rated sequential write speed

  • Zippy to copy large ISO files

  • Includes Acronis True Image software

The inconvenients

  • High cost per gig at 4TB and 8TB capacities

  • A little slow in PCMark and 3DMark tests

  • Must register player to upgrade warranty from two to five years

The essential

Sabrent’s Rocket 4 Plus is a durable internal PCI Express 4.0 SSD tested at its mammoth 8TB maximum capacity. It’s expensive and found to be a little slow in our tests, but it’ll let you max out an M. 2.
