SanDisk Extreme Pro 32gb Compact Flash Card

Sandisk01

The latest DSLR cameras are designed to work at speeds their predecessors can only dream of. Features such as 1080P video recording make lightning fast read/write speeds a necessity. If you are an owner of a newer cameras such as the Canon EOS 5D Mark II, then the Sandisk Extreme Pro Compact Flash card maybe worth checking out. Released this past October, this CF card features unprecedented 90 MB/s max read/write speeds.

The Extreme Pro series is available in 16GB, 32GB and 64GB capacities and are UDMA 6 enabled. It features Power Core Controller & Enhanced Super-Parallel Processing “ESP” designed by SanDisk to increase the card’s performance level. The card is rated for use in temperatures from -25°C to 85°C and can withstand falls from a height of up to 9 feet. Plus it has Sandisk’s lifetime warranty.

Reviewing the new SanDisk Extreme Pro Compact Flash card is easier said than done due to its blazing speed. The card is so fast that every device I tested with the SanDisk Extreme Pro Compact Flash Card was slower than the CF card.

After testing the card with multiple cameras including fairly recent offerings from Nikon and Canon I discovered the real world benefits from the SanDisk Extreme Pro Compact Flash Card come when shooting fast moving action or sports.


Sandisk keeps things mostly Green with a small cardboard package with the CF card found within. They do use a plastic tray to secure the card when a cardboard one would work just as well.

Besides the CF card, Sandisk provides a protective plastic case for storing the card outside of the camera. As an added bonus Sandisk also includes the serial number to activate a copy RescuePRO recovery software that is available via download.

The SanDisk Extreme Pro Compact Flash Card will look familiar to owners of prior Sandisk Extreme Compact Flash cards. On the front is the Sandisk Label indicating the card’s size, model and speed while on the back is a blank area for labeling the card.

For today’s review we received the 32 GB SanDisk Extreme Pro Compact Flash Card. Freshly formatted the card held 6730 highest resolution (10.1 megapixels) non-RAW jpg shots on my Canon EOS 400D.

Digital SLR cameras require fast CF cards primarily in burst mode when the camera needs to offload data from its buffer quickly. There are several variables that affect the speed of this transfer such as large files, small buffers and slow controllers; all of which can cause delays in writing to a card yielding lower frames per second.

When transferring data from the CF card to a hard disk interface; the card’s speed, operating system used, and card reader performance are areas where bottlenecks can occur. SanDisk has a new Express Card Reader, which operates under OS X and supposedly yields close to 90 MB per second speeds. Sadly, USB based card readers will not be able to achieve anywhere near those numbers due to limitations of the interface’s speed.

For benchmarking, I used ATTO DiskBenchmark and DiskBench. For comparison I used the ATP ProMax II CF 8GB, which is also a CDMA enabled CF card and is rated at 45 MB/sec speeds. To test transfer speeds, I used the Kingston 19-in-1 Card Reader.

Looking at the ATTO DiskBenchmark results the read speeds for the ATP top out around 24 MB/s while the Sandisk hits 28 MB/s and for the write speeds 17 MB/s for the ATP and 21 for the Sandisk. So there is a slight speed gain with the SanDisk Extreme Pro Compact Flash Card with a USB interface, however the bottleneck seems to be the USB interface in the PC operating system not the CF card itself.

DiskBench is used to tests disks and drives in real world situations copying and reading files you choose. For this benchmark I used a 720 MB file. Once again the Sandisk Extreme Pro comes out on top.

During real world testing with a Canon 40D and Nikon D300 we saw no discernable difference between the SanDisk Extreme Pro Compact Flash Card and CompactFlash cards rated at 60 MB/sec. Using the Canon 40D we were able to keep our finger down on burst mode almost indefinitely getting about 6.3 frames per second. The older Canon 400D operating on the highest quality with RAW mode was able to handle a burst of 6-7 shots before succumbing to the camera’s slower buffer.

Here are some shots one of my colleagues took using the Sandisk Extreme Pro with the Canon 40D at an NHL game.

Researching online literature the most extensive testing was performed by CNET’s Lori Grunin who tested the SanDisk Extreme Pro Compact Flash Card with the Nikon D300 and Canon 5D Mark II. The burst completed on the Extreme Pro 1.3 seconds faster than the Extreme version on the Nikon. While on the Canon 5D Mark II there was a 1.9 second savings for burst completion in the JPEG +RAW mode.

In plain English, unless shooting long bursts using the highest resolution JPEG +RAW files there really are no noticeable performance gains using the Extreme Pro over the last Extreme card.

Conclusion:

The Sandisk Extreme Pro is the fastest CF card on the market. It is best designed to work with the newest DSLR models which are CDMA 6 enabled. The photographer who captures lots of fast moving action such as sporting events will see the most benefits from the new SanDisk Extreme Pro Compact Flash Card especially when shooting in the best resolution in JPEG +RAW mode. Otherwise the performance gains are slight.

As newer cameras are released they will be optimized for the fastest card on the market. On these cameras we will see the true gains from the SanDisk Extreme Pro Compact Flash Card.

The other drawback of the SanDisk Extreme Pro Compact Flash Card is the price. Its high price may turn off many consumers when the slightly slower Sandisk Extreme cards are available for a few hundred dollars less for comparably sized cards; unless you want the 64 GB version which is only available in the Extreme Pro model.

Unfortunately the card is too fast for most cameras on the market and unless using the SanDisk Extreme Card Reader you will not see the fastest speeds with file transfers to the PC or Mac. Like all other storage media as the product stays out of the market for longer duration prices usually drop significantly. Unless you need the fastest CompactFlash card market and your camera and/or computer can see the real world gains I would recommend to wait a little while before investing in this card.

    I bought it for a friend. The price is high but for a professional earning good it’s a good investment.

    I noticed that while the Extreme IV 16 GB card transferred to my Sanho Colorspace UDMA backup at around 37MB/second, for some strange reason the Extreme Pro 32 transferred at only 26 or so MB/second. Instead of being faster, or at least the same, it was much slower!!

    Has anyone else noticed this or something similar.

  • Waja

    I bought the SanDisk Extreme 32GB CF (non Pro) 60 MB/s. This card is much slower writing data than the Extreme IV 16 GB card. The Extreme IV 16 GB card scored 32.6 MB/Sec read and 24.7 MB/Sec write. The Extreme 32GB card scored 30.7 MB/Sec read and 18.7 MB/Sec write. This was using a Kingston 19 in 1 USB reader model FCR-HS219/1.

    You should have tested this card with a FireWire 800 card reader! I have a 60mb/s Extreme card and in a quick test it transfers 1.5gb of data to my MacBook Pro in 30 seconds (that’s 50mb/s), compared to doing it in almost 1 min 30 seconds with a USB card reader. UDMA cards will always be about the same speed, or slower, than standard cards in USB readers. If you really want to make the most out of them you HAVE to pair them with FireWire 800 card readers (or USB 3 once you can get them). I’ve just ordered an Extreme Pro like the one you talked about here and will be speed testing that asap and writing an article and making a video to demonstrate this very point.

    Nice article :) Would like to see a comparison between FW 400 vs FW 800 vs USB 2

  • IfteShaikh

    I’ve just bought one of the 32GB cards from an eBay seller, but my Canon EOS 400D did not recognise it at first, then after formatting it, the capacity is only shown as 945MB. I’ve tried reformatting it on my laptop, but it is still showing the same capacity. Can anyone enlighten me as to what’s going wrong and how to fix this please?

    • MichelleHG

      Hi, did you find a solution to this question as I have the exact same camera, CF card and issue. Your reply would be appreciated: michellejhadwick@gmail.com
      Regards  Michelle.

      Apparently some people sell fake CF cards on eBay, just a basic card with a fake label.

  • Mrali

    Can I use a faster CF card with my old SLR camera?
