The Sabrent Rocket X5 looks like it is going to be an exciting product. While PCIe Gen5 NVMe SSDs promised to deliver twice the sequential speeds of PCIe Gen4 NVMe SSDs, that often has not translated into reality with early drives falling well short of that mark, despite a large price premium. The Sabrent Rocket X5 is not out yet, but the development update shows promising progress.
Sabrent Shows Progress Building the Fastest PCIe Gen5 M.2 SSD
One of the big features of the Sabrent Rocket X5 is its form factor. This is a M.2 2280 (80mm) SSD. M.2 SSDs have become the defacto standard for workstations and even some internal server applications. Sabrent showed the label for the 1TB Rocket X5, but it showed the performance of the 2TB model.
These new drives achieve higher performance but also require a lot more cooling. As a result, Sabrent is developing a M.2 cooler that allegedly does not have a high-pitched fan noise. At the same time, it feels like the industry needs a better solution for M.2 SSDs in general than sticking small fans on each SSD.
The performance of the 2TB Sabrent Rocket X5 is very promising, achieving over 14GB/s sequential reads and 12GB/s sequential writes. This feels more like the numbers we would expect from doubling the PCIe bandwidth than many of the early Gen5 SSDs that would hit 10GB/s sequential writes on this benchmark.
The random 4K low queue depth numbers are good, but those higher queue depth 4K numbers are very strong. Just for comparison (CDM versions are different so the RND4K Q32 numbers are using different thread counts) here is the Sabrent Rocket 4 Plus 1TB M.2 PCIe Gen4 NVMe SSD Review result we got.
That is a huge upgrade.
We are excited for PCIe Gen5 NVMe SSDs. Something that feels a bit different in this generation is that the more we see these drives, the more we think there will be a market for lower-power PCIe Gen4 drives that do not offer the performance, but also require less cooling. Still, for those that just want to go fast, we hope the Sabrent Rocket X5 comes out soon so we start the era of high-performance PCIe Gen5 M.2 SSDs.
