SanDisk Extreme PRO 128GB SDXC UHS-I 2-pack

Two new 128 GB SDXC UHS-I memory cards built for photographers and videographers who need reliable high-speed capture. The Extreme PRO series targets creative professionals recording 4K UHD video or shooting rapid bursts. Each card delivers up to 200 MB/s read speed and 140 MB/s shot speed with UHS Speed Class 3 (U3) and Class 10 ratings. The pair suits workflows that demand consistent write performance in the field.

QuickFlow offload and rugged build

SanDisk QuickFlow Technology optimises media offloads for faster post-production when paired with a compatible SanDisk Professional Pro-Reader SD and microSD reader sold separately. The cards are engineered to withstand weather, water and shocks so they keep working in less-than-ideal conditions. This durability protects footage during outdoor shoots and travel. The combination of accelerated transfer and physical resilience reduces downtime between capture and edit.

200 MB/s read speed decides fit

The single specification that determines whether this pack fits your kit is the 200 MB/s maximum read speed. It sets the ceiling for ingesting 4K UHD video and high-resolution stills into your editing system. If your card reader or host device cannot sustain UHS-I throughput, the card will fall back to lower speeds. Buyers who need sustained write rates above 140 MB/s or capacities beyond 128 GB per card should look elsewhere.

Questions about this item

How long before the 128 GB Extreme PRO cards wear out from repeated 4K recording cycles?

The cards are built to withstand weather, water and shocks, but SanDisk does not publish a write-endurance figure for this model; plan to replace them if sustained write errors appear or after several years of heavy daily use.

What bottleneck appears first when shooting continuous 4K at 140 MB/s on these UHS-I cards?

The UHS-I bus caps sustained throughput, so the card’s 140 MB/s peak write speed is the practical ceiling; camera buffer depth and UHS-I signalling then become the limiting factors.

Do the cards run hot or draw extra power during all-day 200 MB/s offloads with QuickFlow?

QuickFlow optimises transfer up to 200 MB/s off-camera; the cards themselves draw standard SD bus power and run at normal temperatures during extended read sessions.
