Sabrent Rocket 4 Plus: flagship-adjacent speed, mid-range price

The pitch for a drive like this one is straightforward: get most of the way to flagship PCIe 4.0 sequential performance, at a price that isn’t flagship. Rated at 7,100 MB/s read and 6,600 MB/s write, it lands close to the very fastest drives in this generation without asking for the same price those drives command.

What the sequential numbers mean in practice

Sequential read and write speed is the number that shows up in marketing, and it does matter for large-file transfers: game installs, video export, big asset moves. It matters less than the spec sheet implies for a lot of everyday desktop use, where random small-file access and the operating system’s own overhead dominate more than raw sequential throughput does. For the use cases where sequential speed genuinely is the bottleneck, this drive delivers real, close-to-flagship numbers.

Heat and sustained load

Any drive pushing PCIe 4.0-class speeds generates real heat under sustained load, and this one is no exception: expect it to run warm during a long sequential write, and plan cooling accordingly. Most current motherboards include an M.2 heatsink shroud that handles this without any extra part to buy; a board without one is worth pairing with an aftermarket heatsink rather than running the drive bare under heavy sustained use.

Where the discount comes from

A drive at this price point competing on sequential numbers close to the flagship tier usually gives something back elsewhere: brand recognition, marginal differences in sustained-write consistency once a drive’s cache region is exhausted, or firmware polish accumulated over more product generations. None of that shows up in a spec-sheet comparison, and for a gaming or general desktop build it rarely matters in practice. For a drive that’s going into 24/7 server or NAS duty with a genuinely demanding sustained-write pattern, a drive built specifically for that duty cycle is the more conservative choice.

Verdict

Buy it for a gaming PC or an editing build that wants real PCIe 4.0 speed without flagship pricing. For sustained, server-class write loads, spend the extra money on a drive rated specifically for that duty cycle instead.
