Sabrent Next-Gen Rocket 4 Plus PCIe 4.0 SSD Designed to kick Samsungs ass at 6850 MB/s seq writes
On facebook the designer behind the Phison E18 controller that is empowering this Rocket 4 Plus PCIe 4.0 SSD had a simple thought and target, he wanted a controller that would kick Samsungs ass.
And in that mindset the Rocket 4 Plus NVMe SSD has been announced, powered by the new Phison PS5018-E18 SSD controller the SSD series would deliver a massive 7,000 MB/s sequential read and 6850 MB/s sequential write speeds (!). Of course these numbers only tell one side of the story.
These numbers are above the specs Samsung recently announced with the 980 PRO. The Sabrent Rocket 4 Plus will become available in 500 GB, 1 TB, and 2 TB models . These numbers mentioned are approaching the bandwidth limits of PCIe 4.0 x4 slots. Pricing and availability was not announced.
| Sabrent Rocket 4 Plus | Sabrent Rocket | Samsung 980 Pro | |
| NAND Type | TLC | TLC | TLC |
| Controller | Phison E18 | Phison E16 | Samsung Elpis |
| Sequential Read | 7000 MB/s | 5000 MB/s | 7000 MB/s |
| Sequential Write | 6850 MB/s | 4400 MB/s | 5000 MB/s |

You know, issue at hand is not write speed. Users mostly write only tiny amount of data to drives. And most drive's activity is actually reading.
On top of that, even read speed is not that important with most of games. That's because they use bit too heavy compression on their data files, and CPU is limiting factor.
Good thing about PS5 is that Epic stopped ignoring development of PC storage HW and started to deal with their slow decompression. It will likely take years before games have either repack to NVMe optimized compression, or are directly released with it, so read speed actually has appropriate impact.
They should have had compression that at least enables average gaming 3.3~3.8GHz CPU (Sandy and newer) to read 500MB/s from SSD while decompressing it to whatever it can. (Like 600~800MB/s.)
Those storages are around for so long, and one mostly sees like 200~400MB/s read.

Yeah, lets see.
My HDDs have write speeds of few GB/s! But only till RAM cache is empty!!!
Let's wait real world scenario and independent testing.
But as 970Pro user I'm disappointed with 980Pro. Reason for me buying 970Pro was huge endurance what might matter when SSD starts to fill up. Also on all tests 970Pro killed others in random loads.

It's nice to see manufacturers starting to take PCIe 4.0 SSDs seriously.

Peak sequentials are nice and all, but i'll reserve judgement for random I/O at low queue depths - eg. actual real world use.
Generally interested in a top tier PCIe 4 SSD for when I build a new Zen3 system.
