Overview

The SanDisk Extreme 64GB CompactFlash bundle pairs two UDMA 7 CF cards with a multi-format USB card reader. Each card delivers sequential read speeds up to 120MB/s and write speeds up to 85MB/s — the read speed determines how fast you can ingest files to a workstation, while the write speed dictates in-camera buffer performance. The VPG-20 (Video Performance Guarantee) rating is the critical spec for video shooters: it certifies that the card will sustain a minimum 20MB/s write throughput without interruption, which prevents the dropped frames and recording stops that plague slower media. For stills, 85MB/s write speed keeps the buffer cycling efficiently during burst sequences, though cameras with extremely deep buffers and high-resolution sensors may still outpace it.

This bundle targets DSLR photographers who still rely on CompactFlash — specifically users of bodies like the Canon 5D Mark III, 7D Mark II, or Nikon D810 and D300S. With 128GB of total capacity across two cards, you get enough storage for a full day of event or wedding shooting without resorting to in-field card swaps. The included combo reader handles CF, SD, Micro SD, M2, and MS formats, which is convenient for multi-camera workflows, though its USB interface will not saturate the cards' read bandwidth. The SanDisk Extreme line is built for field durability — the RTV silicone coating and shock/vibration testing give these cards a resilience advantage over consumer-grade media. For photographers maintaining CF-based camera systems, this bundle offers a cost-effective way to stock up on proven, reliable storage.

Pros & Cons

👍 Pros

  • 120MB/s read speed accelerates card-to-computer transfers, reducing post-shoot ingest time for large RAW file batches.
  • VPG-20 certification guarantees sustained 20MB/s writes, preventing dropped frames during continuous video recording.
  • The two-card bundle provides 128GB total capacity, enough for extended shoots without swapping media.
  • RTV silicone coating and rigorous shock/vibration testing make these cards reliable for outdoor and event shooting conditions.
  • Included multi-format card reader eliminates the need to purchase a separate CF reader for file transfer.

👎 Cons

  • Write speed of 85MB/s is below the fastest UDMA 7 CF cards available, which can limit buffer clearing speed on high-resolution bodies like the D810.
  • CompactFlash is a legacy format — newer camera bodies have moved to CFexpress or SD, limiting the long-term utility of this investment.
  • The bundled card reader uses USB 2.0 speeds, which will bottleneck the cards' 120MB/s read capability during transfers.
  • 64GB capacity per card is modest for photographers shooting uncompressed RAW, yielding roughly 1,000–1,400 frames per card depending on sensor resolution.
  • No included carrying case for the cards, which is an oversight for a bundle marketed to working photographers.

Frequently Asked Questions

These are standard UDMA 7 CompactFlash cards compatible with any camera or device that accepts a CF Type I slot. Confirmed compatibility includes the Nikon D300S, D810, Canon EOS 7D, 7D Mark II, and 5D Mark III, among other professional DSLRs with CF card slots.
VPG-20 guarantees a minimum sustained write speed of 20MB/s, which ensures uninterrupted video recording without dropped frames. For stills, the sustained write rate determines how quickly the camera can flush its buffer to the card during burst shooting.
Sequential write speeds of up to 85MB/s are achievable during large file transfers. In-camera write performance depends on the camera's CF controller — most DSLRs cannot saturate the card's full write bandwidth, so the practical bottleneck is typically the camera body, not the card.
Yes. The bundle includes a combo memory card reader with slots for CF, SD, Micro SD, M2, and MS/MSPD cards, connecting via USB for file transfer to a computer.
SanDisk rates the Extreme CF line for resistance to shock, vibration, and temperature extremes. The cards feature an RTV silicone coating for shock and vibration protection, and they are tested to operate from 0°C to 70°C.
