Sabrent's Rocket X5 PCIe 5.0 NVMe SSD Shown Hitting 14 GB/s Read Speeds
The first batch of PCIe 5.0 NVMe SSDs didn't quite deliver on the promise of doubling performance from PCIe 4.0 NVMe SSDs, but now it appears that Sabrent has managed to work some magic with its upcoming Rocket X5 SSD. The SSD is still based on the same Phison E26 controller as all other current PCIe 5.0 NVMe drives and from what we know, the controller is paired to Micron's 232-layer B58R NAND, a combination that should be able to reach 2400 MT/s across eight channels. However, it's not the only drive with this combination of components, so it seems like the magic here might be in the firmware.
A 2 TB version of the Rocket X5 was tested in CrystalDiskMark 8.0.4 and reached a read speed of 14,179 MB/s or just over 14 GB/s, with write speeds trailing somewhat at 12,280 MB/s. The random 4K numbers are looking good too with 106 MB/s for reads and 448 MB/s for writes, a step up from the competition at least, if not a major one with regards to the read speed. The downside you ask? Sabrent has equipped the Rocket X5 with not only a heatsink and heatpipes, but also a tiny fan, which is likely to add some noise at some time in the future when the fan starts to give up. We obviously don't know the price of the Rocket X5 either, but Sabrent tends to have competitively priced products.
