Additionally, These SxS memory cards can use the industry-standard PCIe platform
as an interface to realize higher transfer speeds up to 8 Gb/s (1,000 MB/s).
These Sony SxS cards offer wear-leveling (data-defect minimizing function)
and data refreshing capabilities and are subjected to a series of strict quality
assurance tests, including checks on recording blocks, temperature cycles, and
In addition to its enhanced frame rate capture capability, these SxS memory
cards offer improved reliability and data-error correction. Additionally, you
benefit from the data-defect minimizing function for secure data recording and a
"power failure management" function for re-creating video clips in case of
sudden power loss or accidental card ejection during recording.
Its high-reliability is continuously verified through strict inspections and
various tests throughout the manufacturing process. In the event of data loss or
