SANDISK 256GB Extreme PRO SD Memory Card, Up to 200MB/s Read Speeds, UHS-I

No. 01 — Demanding 4K video and high-burst still photography

SANDISK 256GB Extreme PRO SD Memory Card, Up to 200MB/s Read Speeds, UHS-I

$89.164.870,383 ratingsOur score 8.0/10

The Extreme PRO tier is built to maintain the write throughput needed for intensive burst photography and continuous 4K video. It represents a larger financial investment, but it protects against card-induced buffer lockups. Check whether your camera supports proprietary UHS-I overclocking to achieve the full 200MB/s transfer rate.

  • Professional-tier sustained write performance
  • High 200MB/s maximum read capability
  • Large 256GB capacity for extended production days
  • Noticeably higher price point
  • Peak speeds require compatible proprietary card readers
SANDISK 64GB Extreme PRO SDXC UHS-I Memory Card - C10, U3, V30, 4K UHD, SD Card - SDSDXXU-064G-GN4IN

No. 02 — Moderate-bitrate 4K video and RAW stills

SANDISK 64GB Extreme PRO SDXC UHS-I Memory Card - C10, U3, V30, 4K UHD, SD Card - SDSDXXU-064G-GN4IN

$34.074.820,009 ratingsOur score 7.5/10

The V30 rating guarantees the 30 MB/s sequential write speed required to prevent dropped frames in basic 4K recording. At 64GB, capacity runs out quickly under modern codecs, making it better suited for stills or short clips. For sustained high-bitrate or high-frame-rate video, plan on faster V60 or V90 media.

  • V30 rating prevents dropped frames in standard 4K
  • Consistent write reliability across camera brands
  • Cost-effective option for routine photography
  • 64GB capacity limits long continuous takes
  • UHS-I interface caps practical offload speeds
SanDisk 128GB Ultra microSDXC UHS-I Memory Card - Up to 140 MB/s, C10, U1, Full HD, A1, Micro SD Card - SDSQUAB-128G-GN6MN

No. 03 — Full HD capture and auxiliary device storage

SanDisk 128GB Ultra microSDXC UHS-I Memory Card - Up to 140 MB/s, C10, U1, Full HD, A1, Micro SD Card - SDSQUAB-128G-GN6MN

$30.484.717,886 ratingsOur score 6.8/10

Carrying only a U1 rating, this microSD card lacks the sustained write threshold needed for reliable 4K video pipelines. It handles standard 1080p recording and general file storage adequately. Using it in high-bitrate cameras invites buffer stalls and write errors.

  • 128GB capacity offers generous low-bitrate storage
  • Low price per gigabyte
  • Sufficient transfer rates for 1080p video
  • U1 classification risks dropped frames in 4K
  • Write speeds lag far behind read ratings
SANDISK 256GB Ultra SD Memory Card, Up to 150MB/s Read Speeds, UHS-I

No. 04 — Bulk high-resolution still capture without video demands

SANDISK 256GB Ultra SD Memory Card, Up to 150MB/s Read Speeds, UHS-I

$61.994.778,976 ratingsOur score 6.7/10

Offering high capacity and 150MB/s reads, this full-size card handles large volumes of still images cleanly. However, the Ultra tier does not guarantee the sustained write speeds needed for demanding video codecs. At this price point, consider whether a V30-rated alternative offers better future-proofing for your body.

  • Generous 256GB capacity
  • Full-size SD build requires no adapter
  • Quick 150MB/s read performance for offloads
  • Price approaches faster V30-rated options
  • Uncertified for sustained high-bitrate video writes
SanDisk 128GB Ultra SDXC UHS-I Memory Card, Up to 140MB/s, C10, U1, Full HD, SD Card, SDSDUNB-128G-GN6IN

No. 05 — Full HD video and general still shooting

SanDisk 128GB Ultra SDXC UHS-I Memory Card, Up to 140MB/s, C10, U1, Full HD, SD Card, SDSDUNB-128G-GN6IN

$34.904.778,976 ratingsOur score 6.2/10

While read speeds reach up to 140MB/s, the card carries a C10 and U1 rating that restricts it to 10MB/s sustained write floors. This design is engineered for Full HD capture and modest burst rates. High-bitrate video will quickly choke the buffer, necessitating a step up to V30.

  • Respectable 140MB/s read speed for file transfers
  • Native SD form factor fits standard camera slots
  • 128GB capacity fits moderate shooting days
  • U1 rating risks frame drops on 4K video
  • Substantially slower write speeds than read figures
SanDisk 128GB Ultra SDXC UHS-I Memory Card - 100MB/s, C10, U1, Full HD, SD Card - SDSDUNR-128G-GN6IN

No. 06 — Full HD recording and entry-level still photography

SanDisk 128GB Ultra SDXC UHS-I Memory Card - 100MB/s, C10, U1, Full HD, SD Card - SDSDUNR-128G-GN6IN

$33.054.790,636 ratingsOur score 6.0/10

Rated Class 10 and U1, this card guarantees only 10MB/s continuous write speed, limiting its utility to 1080p footage and standard continuous stills. Buyers aiming for 4K video will encounter buffer stalls and dropped frames. It is reasonably priced for legacy cameras and general document storage.

  • Full-size SD form factor avoids adapter issues
  • Dependable for standard 1080p recording
  • Broad compatibility with older camera hardware
  • U1 rating inadequate for modern 4K workflows
  • Modest 100MB/s maximum read speed
SANDISK 32GB Ultra SD Memory Card, Up to 120MB/s Read Speeds, UHS-I

No. 07 — Firmware updates and older legacy camera bodies

SANDISK 32GB Ultra SD Memory Card, Up to 120MB/s Read Speeds, UHS-I

$19.994.778,976 ratingsOur score 5.7/10

A 32GB SDHC card is strictly an emergency spare or intended for older equipment with partition limits. The cost per gigabyte is poor compared to 128GB or 256GB alternatives. It suits basic JPEG shooting or firmware updates where capacity is secondary.

  • Compatible with legacy SDHC-only devices
  • Native full-size SD card format
  • Consistent 120MB/s read ceiling
  • Poor value per gigabyte at current pricing
  • 32GB fills rapidly on modern sensors
SanDisk 32GB Ultra 100MBs SDHC Memory Card

No. 08 — Basic JPEG shooting in older camera bodies

SanDisk 32GB Ultra 100MBs SDHC Memory Card

$20.114.76,658 ratingsOur score 5.3/10

A legacy 32GB SDHC card that lacks modern V-ratings, ruling it out for high-bitrate video workflows. It functions reliably in older bodies or as a low-cost card for JPEG still capture. Modern continuous shooting will quickly saturate the limited buffer write speeds.

  • Inexpensive spare card for legacy equipment
  • Sufficient speed for standard JPEG captures
  • Wide compatibility with older SDHC hardware
  • Lacks V30 rating needed for stable video capture
  • 32GB capacity fills rapidly
INLAND 32GB SDHC Flash Memory Card Standard Full Size SD Card (2 Pack)

No. 09 — Audio recorders, trail cameras, and legacy hardware

INLAND 32GB SDHC Flash Memory Card Standard Full Size SD Card (2 Pack)

$28.494.637,628 ratingsOur score 5.3/10

This multi-pack provides disposable, low-capacity storage for field backups, audio recorders, or legacy cameras. The 32GB ceiling per card is restrictive for modern high-megapixel RAW files and high-definition video. Verify write class certifications before attempting any continuous capture.

  • Two-pack provides an immediate backup card
  • Full-size SDHC compatibility for older equipment
  • Low risk for non-critical secondary devices
  • 32GB capacity is limiting for modern media
  • Speed ratings and sustained writes are unexceptional
