64 GB SDXC™ UHS-I Card

SanDisk Extreme Pro  SDXC™ UHS-I Memory CardsSo you finally went out and bought that high-end dSLR and you are not about to put some cheap, slow memory in your camera. Instead, you search for the premium memory card that offers the same level of performance as your new camera. On the top of the short list you will likely find SanDisk's Extreme ProŽ SDXC™ UHS-I Memory, which is designed to meet the demands of the professional photographer and has established a reputation among demanding users by providing the fastest SDHC and SDXC cards on the market. With write speeds up to 90 MB/sec and read speeds as high as 95 MB/sec (633X), it's no wonder that professionals choose SanDisk's Extreme Pro memories for high-speed burst shooting and cinema quality high definition video capture. We are reviewing the 64GB version, which provides more space for capturing RAW+JPEG, sequential bursts shots and uninterrupted video files. The larger size allows users to capture a whole shoot without interrupting the session to upload files to a computer or swapping out the memory card. The card's built in Advanced Wear Leveling and Error Correction Code engine enhances endurance and reliability.

SanDisk Extreme Pro  SDXC™ UHS-I Memory CardsDurability
Speed is not the only area where the Extreme Pro SDXC™ UHS-I Memory Cards excel. These cards are extremely durable, withstanding up to 500Gs of shock, airport X-ray machines, and up to 72 hours in 1m of salt or fresh water. In addition, these cards can operate in extreme temperatures ranging from -13 to 185 degrees Fahrenheit. The Extreme Pro® SDHC™ delivers the highest video performance with a Class 10 rating plus UHS Speed Class 1 (U1) and comes in four memory sizes (8GB, 16GB, 32GB, and 64GB). UHS Speed Class 1 (U1) designates a performance option designed to support real-time video recording with UHS-I enabled host devices. However, full 1080p30 HD video and 3D video support may vary based upon the host device, file size, resolution, compression, bit rate, content, and other factors. The SanDisk Extreme Pro SDHC/SDXC UHS-I Card is backed by a lifetime limited warranty.

 


Canon 5D Mark IIIPhotos
Our tests were performed on a new Canon 5D Mark III, which is designed to accept both SD and Compact Flash memory. We installed the 64 GB Extreme Pro SDXC UHS-I Memory and set the camera to take Raw+L (22 megapixel) photos. Each shot takes approximately 34MB of memory. The camera indicated that 1655 shots were available in this mode. This setting is ideal for professional photographers who need both compressed and uncompressed image formats for weddings and other important events for post editing.


Video Recording Times
The 5D Mark III has the ability to record 1080p video in both IPB (compressing multiple frames for the most efficient use of storage) and ALL-I (compresses one frame at a time suited for editing). The high recording rate during the ALL-I recording mode makes it challenging for memory cards. However, even at the very fast recording rate of 685 MB per minute, the Extreme Pro SDXC UHS-I has no problem keeping up all while providing almost an hour and a half of recording time with the 64 GB memory.


SanDisk Rescue Pro DeluxeRescuePRO® Deluxe
The SanDisk Extreme Pro SDHC/SDXC UHS-I Card comes with a free 1-year subscription of RescuePRO Deluxe, a powerful utility designed to recover lost pictures or videos. The package includes a card with a serial number. Users simply go the RescuePRO Deluxe website (via LC Technology International, Inc.) and download the appropriate version (Windows or Mac) for their computer. The zipped file is only about 25 megabytes with a single installation file required to install the software. The file recovery utility can recover photos, movies, and data files as well as backup media and wipe media. I took the 64GB SD memory card that had been completely erased by the camera and ran the Recover Photos selection.

The software is easy to use and the user can select from Recover Photos, Recover Audio/Video, Recover Files, Backup Media, Wipe Media, and Help from the main menu. We ran a test on the Extreme Pro SDXC UHS-I Card to see if it could recover photos that had been previously erased by the camera after the download process. It took almost an hour to scrub the 64 GB SD card, but it fully recovered all of the photos residing on the card. The software supports SD™/SDHC™/SDXC™, CompactFlash, SmartMedia, MMC, Memory Stick™, XD Cards, Microdrive, PCMCIA, Video CD, and DVD.


Performance
We took the SanDisk Extreme Pro® SDXC™ UHS-I Memory Card on several shoots in various environmental conditions using different settings that included RAW and Normal modes. The most demanding condition for this memory is while shooting RAW+L (JPG) when the transfer rate can be very high, especially if in the burst mode. Our Canon 5D Mark III can shoot 7 frames back-to-back (burst mode) before stopping to wait for the data to transfer to the memory. Changing the setting to RAW only results in a slightly lower data rate allowing the camera to shoot up to 15 back-to-back photos in the burst mode. If the setting is L (JPEG), the memory has no problem keeping up with the data rate. Normal shooting was never a problem for us in terms of waiting for the data to transfer. We only performed these stress tests to check the memory. Shooting video was transparent to the memory speed and we never encountered any issues even in the highest resolution 1080p mode.

Image Pixels File Size Possible Shots Max Burst Rate
L (JPEG) 22M 7.0M 8,000+ No Limit
L (RAW) 22M 27.1M 2,000+ 15
L (RAW+JPEG) 22M 7.0M + 27.1M 1,600+ 7

Conclusion
The SanDisk Extreme Pro® SDXC™ UHS-I Memory Card (64GB) is a product that has earned the trust of professional photographers who need high performance and cannot afford to have memory fail on them in the field. The rugged design of the Extreme Pro® SDXC™ UHS-I Memory Card and its ability to meet performance requirements under demanding environmental conditions makes this the memory of choice. When you spend thousands of dollars on camera gear, the last thing you need is memory that you cannot rely on. Sandisk continues to provide that best performance memory in the industry and delivers with the Extreme Pro® line. It's the only memory we'll put into our high-end full-frame DSLR.
