SUNEAST ULTIMATE PRO WHITE Series SE CFexpress Type B Card 128GB

The WHITE Series SE is SUNEAST's entry into CFexpress Type B, and at 128 GB it is the card you buy in quantity rather than one big card you cannot afford to lose. Maximum read is 1550 MB/s, which is where the value shows up: offloading a full card to an NVMe reader is quick, and the camera buffer clears fast enough for long stills bursts.

Maximum write is 550 MB/s with sustained transfer at 150 MB/s, so treat it as a stills and moderate-bitrate video card rather than a sustained 8K RAW card. It carries a five year warranty from date of purchase.
