Sabrent's Rocket 4 was one of the first PCIe 4 SSDs out of the
gate. It's not even close to newer PCIe 4 NVMe SSDs on sustained throughput
Don't let that fool you however. The Sabrent Rocket 4's real
world performance is surprisingly good, even when compared to the
top dogs. If you're looking for a cheaper PCIe 4 option, or an SSD
that would pair nicely with your PlayStation 5, this might be a
Design and specs
The Rocket 4 is a standard 2280 (22mm wide, 80 mm long) M.2/NVMe
SSD using four PCIe 4 lanes. The NAND is Toshiba BiC S4 96-Layer
TLC and the controller a Phison E16. There's a gigabyte of DRAM
cache on the 2TB capacity we tested, and the drive was going for US$300 (AU$439.99) on Amazon at the time of this
There are also US$90 (AU$129.99)/500GB and US$150(AU$229.99)/1TB models available. Nicely, there's a
1800TBW (TeraBytes Written) per 1TB of capacity rating which is
quite a bit more than with most drives. The warranty is five years,
assuming you don't overshoot the TBW rating which few (if any
users) will ever do.
We saw the 5GBps read performance Sabrent claimed, but we also
experienced many significantly slower read runs over PCIe 4
(3.2GBps reading). Basically, with 10GB or less employed by our
CrystalDiskMark or AS SSD testing software, we saw a hair over
5GBps. With the 32GB test that we normally run on CrystalDiskMark,
we saw anywhere from 2.8GBps to 4.2GBps read performance.
This is likely a secondary caching issue (NAND as SLC) but it
might also be the way the benchmark is set up. We included both the
8GB and 32GB tests below so you can see the issue. Note that the
drives we compare it to are two of the three absolute fastest SSDs
on the market (the other being Kingston's KC3000).
For some reason the
Rocket 4 lost a bit of steam reading when we upped the
CrystalDiskMark 6 data set from 8GB to 32GB. Normally, read
performance doesn't vary at all. Longer bars are better.
After the benchmarks, the times in our 48GB real world transfers
were a more than pleasant surprise. You might call them redemptive.
This has a lot to do with the limits of operating systems.
The Rocket 4 did quite
well in our 48GB transfers, coming within shouting distance of two
very fast competitors. Shorter bars are better.
Another pleasant surprise was the the Rocket 4's 450GB write
time–the ninth fastest we've seen. This test reveals secondary
cache issues, but the Rocket 4 was largely free of these.
Note that as the drive fills up, NAND for cache dries up and
this type of test proceeds at the native speed of the NAND.
Though this looks less
than impressive, the Rocket 4's time is actually the 9th fastest
we've seen and continues the drives comeback in real world testing.
Note that the Corsair and FireCuda 530 are both top three drives
performance wise. Shorter bars are better.
There's no reason to spend this type of money if you're using
PCIe 3. But just in case, the Rocket 4's performance was slightly
above the PCIe 3 average.
The PCIe 3 tests utilize Windows 10 64-bit running on a Core
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 ASM3242 USB 3.2×2 card. It also contains a Gigabyte
GC-Alpine Thunderbolt 3 card, and Softperfect Ramdisk 3.4.6 for the
48GB read and write tests.
The PCIe 4 testing was done on an MSI MEG X570 motherboard
socketing an AMD Ryzen 7 3700X 8-core CPU, using the same Kingston
DRAM, cards, and software. All testing is performed on an
empty, or nearly empty drive that's TRIM'd after every set of
tests. Performance will decrease as the drive fills up.
Note that some vendors have been swapping slower
parts into their drive after reviews have posted. Sabrent states
this will not be the case with the Rocket 4 or any of the company's
drives. Still, our standard request is to please inform us if your
drive's performance, given a similar hardware platform, varies
significantly from what we saw.
A good drive with limits
The Rocket 4 didn't test well under our synthetic benchmarks in
terms of sustained throughput, but it was quite agile in our real
world tests and like all NVMe drives, has insanely low seek times.
We trust the real world.
By all reports, the Sabrent Rocket 4 should do just fine as a
cheaper option for you gaming/editing PC or your PlayStation 5.
We'd recommend something faster such as the Corsair MP600 Pro XT or Kingston KC3000 for a PCIe 4 PC where pure, raw
speed is the goal—but those drives cost much, much
