Professional CFexpress Type B card

The Sabrent Rocket CFX PRO is a 2TB CFexpress Type B internal SSD built for professional videography and photography. It uses dual PCIe 3.0 lanes to deliver high-speed transfers in a compact form factor. The drive targets creators who need reliable, high-capacity storage for demanding capture workflows.

Sustained write performance

Under continuous load the card maintains write speeds of up to 1300 MB/s, well above the burst ceiling of 1700 MB/s. This steady throughput supports uninterrupted HD recording sessions without frame drops. High IOPS of over 300000 keep random access responsive during mixed read-write workloads.

PCIe 3.0 interface limits

The dual-lane PCIe 3.0 connection caps maximum sequential reads at 1800 MB/s and writes at 1700 MB/s. Real-world sustained writes settle at 1300 MB/s, defining the practical ceiling for long-duration capture. Controller features such as TRIM, LDPC, ECC, SmartRefresh and wear-leveling preserve consistent performance across the drive's lifespan.
