While most PCIe 4.0 SSDs are rated for 10Gb/s or 12Gb/s sequential read speeds, Sabrent has already upped the speed of its drives to 14,000 Mbps and higher. Sabrent doesn’t want to be quicker into the PCIe 5.0 SSD market, which takes full advantage of the PCIe 5.0 interface and pushes the limits of SSD performance.
Thanks to its prototype Sabrent Rocket X5 has already outperformed PCIe 5.0 SSDs available today and is now working with Phison to further optimize its SSD design and firmware to maximize the performance of its PCIe 5.0 drives.
In CrystalDiskMark, the SSD already supports sequential read speeds of 14179 MB/s and write speeds of 12280 MB/s, values that are already far ahead of currently available PCIe 5.0 SSDs.
Sabrent has not commented at this time on what allowed them to achieve these performance figures, although it is most likely a combination of firmware optimization and fast NAND. It is not known at this time which NANDs Sabrent uses in its new Rocket X5 PCIe 5.0 SSD prototypes.
Modern PCIe 5.0 SSDs are designed to push the limits of SSD performance, and that requires a powerful controller, fast NAND, and DRAM. All of these components require power and generate heat, so it’s no surprise that PCIe 5.0 SSDs run at higher temperatures than their PCIe 4.0 counterparts.
Sabrent has stated that all PCIe 5.0 SSDs should be used with a heatsink, noting that motherboard heatsinks will be sufficient on PCIe 5.0 motherboards, and that those who want better cooling can purchase a dedicated SSD cooler. Above, you can see a prototype Sabrent fan SSD heatsink that they claim doesn’t make the high-pitched whine that some other PCIe 5.0 coolers have.
Sabrent’s upcoming Rocket X5 SSD is impressive, and I’d rather try it out. Sabrent has been slow to bring the PCIe 5.0 SSD to market to capitalize on early sales, and it remains to be seen when the PCIe 5.0 SSD becomes available.
