On the other hand, Sabrent says the smaller drive's write performance will trail the other two models, as it tops out at just 2,500 MB per second. The read speeds are consistent across all models of the drive, including the smaller 500 GB model. The Rocket NVMe 4.0 has lofty read and write throughput, with a whopping 5,000 MB per second sequential read speed and 4,400 MB per second sequential writes. Sabrent hasn't specified whether the Rocket uses part of the drive as a SLC write cache, but to get write speeds that high for very long, it almost certainly has to. The drive makes use of Toshiba's 96-layer BiCS TLC NAND, which has always been pretty fast, and a 512 MB DDR4 cache made by SK Hynix to act as a buffer. Four lanes of PCI Express 4.0 connectivity is about as good as it gets for consumer SSDs these days. We see a lot of what we'd expect out of a high end, premium-priced solid state drive listed in the Rocket NVMe 4.0's specs. For now, let's dive into the Sabrent Rocket NVMe 4.0's specs. We'll see how the drive fares under sustained loads later on. The drive has a black and copper label that probably doesn't do much for heat dissipation. This case, which is a bit smaller than a box of curiously strong Altoids, holds a shock-absorbing foam padded interior and, finally, the Rocket NVMe 4.0 itself. SANDRA MODEL CUSTOM SET TORRENT SERIALBeneath the dark, minimal cardstock is a coppery rose gold aluminum shell sealed by a sticker which bears the drive's capacity and serial number. Perhaps owing to its premium pricing, Sabrent ships the Rocket NVMe 4.0 in a pretty spectacular package. SANDRA MODEL CUSTOM SET TORRENT MANUALThe Rocket's manual says a heat sink is required for PCIe 4.0 use, but many motherboards these days come with integrated cooling, so even the version without the heat sink included should be up to the task. The model we received for review does not have the heat sink bundled, so bear that in mind when perusing our test results. All three capacities are available with or without the cooler, and the extra accessory seems to add around $20 to the retail price. Sabrent released two mostly-identical versions of the Rocket NVMe 4.0: a plain gumstick and a drive bundled with a large and rather extravagant-looking heat sink, complete with a trio of copper heat pipes. Still, at the time it was released back in July, it was the most budget-friendly PCIe 4.0 SSD around. On the other end of the spectrum, Sabrent's largest model at 2 TB will cost an eye-popping $399. The 1 TB drive we're looking at today rings up at $199 on Amazon while the smaller 500 GB drive lists for $119. Premium PCIe 4.0 Packaging and Performanceīecause of its beefy specs and relative lack of competition-Gigabyte's Aorus PCIe 4 SSD and Corsair's MP600 appear to be the only other widely available PCIe 4.0 SSDs for now-Sabrent has priced this drive into premium territory. That's the same controller as Gigabyte's PCIe 4.0 SSD, and one of the the only SSD controllers that's widely available at the moment, that can handle fourth-generation connectivity. Today we're going to take a look at the 1 TB variant of that drive, which is built on Phison's PS5016-E16 controller. This seems like a market just ripe for the picking. The good news is that Sabrent has seen that opening and has attempted to fill that void with its Rocket NVMe 4.0 line of M.2 SSDs. That seeming dearth of products flooding the market stands in stark contrast to Ryzen's continued dominance in the world of DIY PCs. Considering that Gigabyte's drive could far outstrip the bandwidth available in PCI Express 3.0 x4 drives, while putting up some solid IOPs figures, it seems that those who feel a need for speed would want these drives, assuming they had a motherboard with a processor and chipset capable of pushing it to the limit. SANDRA MODEL CUSTOM SET TORRENT TORRENTIn the time since then, there hasn't been a torrent of extra-fast flash released by all that many storage vendors even at launch, we only had Gigabyte's Aorus PCIe 4 SSD on hand to test. It's been nine months since AMD unleashed its Zen 2 processors and, more importantly as it related to this article, the X570 chipset with its PCI Express 4 connectivity, into the world.
