Ready for 8K RAW capture

This Lexar Diamond Series card is a 128GB CFexpress 4.0 Type-B memory card built for professional cameras that demand sustained high-throughput recording. It targets videographers and photographers who need reliable storage for extended bursts of high-resolution stills and cinema-quality 8K RAW footage.

IP5X dust proof and 5 m drop proof

The card carries 8-point protection including IP5X dust resistance, survival from 5 metre drops, 70N compression tolerance, vibration resistance across 10-2000Hz and 1500G shock resistance. This ruggedisation means the media withstands harsh location shoots and frequent handling without compromising the stored data.

VPG400 sustained write for thermal stability

A VPG400 rating guarantees a minimum sustained write speed of 3200MB/s, while peak reads reach 3700MB/s and peak writes 3400MB/s. pSLC technology lowers power consumption and extends endurance to 30000TBW, keeping performance consistent during long recording sessions without thermal throttling.
