Sabrent has announced its Rocket 4 Plus SSD, which the company is claiming is the world's fastest NVMe SSD. The Sabrent Rocket 4 Plus SSD's read and write speeds place it beyond the recently leaked Samsung 980 Pro and the PS5's drive. Console architect Mark Cerny has warned future PlayStation 5 owners to wait before making a third-party drive purchase.

Sabrent's Rocket 4 Plus drives are pretty sick!
In regards to the previous 1TB flagship drive mentioned in your last paragraph, which is the Sabrent 1TB Rocket NVMe 4.0 Gen4 PCIe M.2 (SB-ROCKET-NVMe4-1TB), the slower performance speeds you referenced are only if a consumer is utilizing a PCIe Gen 3 port. Being that the drive is Gen4, performance speeds are significantly better with the proper hardware.
"The Sabrent 1TB Rocket Nvme PCIe 4.0 M.2 2280 Internal SSD was designed using PCIe 4.0 which allows for speeds of up to 5000 MB/s (read) and 4400 MB/s (write).
Using a PCIe Gen3 Motherboard Speeds will reach up to 3400 MB/s (read) and 3000 MB/s (write)."
Two thing to note is to know the spec beyond the speed, (number of channel, controller used)
And one main thing is its heating issue. SSD could heats up like crazy, hence all sorts of cooling strip involved in the packaging.
Two of those things are some main reason why cerny ask to hold off until sony perform compability test on the known ssd.
How can the PS5 read 8GB/s compressed and 5.5GB/s uncompressed. Usually gzip has a cpu computational overhead, so I think you got those numbers backwards, mate.
Stay away from Sabrent's products. They are extremely unreliable.

them numbers are correct and actually higher with Sony acquiring another compression software licence
