Fastest SDHC Card on the Market, Make Sure Your Camera Supports It Though..., April 5, 2011
Length:: 5:32 Mins
The SanDisk Extreme Pro SDHC UHS-1 is the fastest SDHC currently on the market. That being said, I must point out that this card uses the UHS-1 standard which most cameras in existence currently do not support. I have the Nikon D7000 and as far as I can tell, it is the only camera that supports this card. Currently you can pick these cards up for about 75 dollars for the 16gb and 150-170 for the 32 gb. However, I suspect that as more cameras are released that support this card, you will see the price go up.
This card writes and reads at a minimum of 45 mb/second. This is 15 mb/s than the former fastest SDHC card on the market, the SanDisk Extreme Class 10.
Even if you do not currently have a camera that supports UHS-1 this card will still work and is backwards compatible with SDHC and SHXC devices. However, the card will revert back to standard Class 10 speeds approximately.
I could go on and on about the quality of SanDisk but I won't. Simply put, they make some of the best memory for cameras out there.
This is a great card, but it is not for everyone. I prefer it because I only shoot RAW (NEF for Nikon) and the files are typically between 25mb - 30mb. The Nikon D7000 16.2MP DX-Format CMOS Digital SLR with 3.0-Inch LCD (Body Only) has a buffer of 10 RAW photos. When I get to the end of the buffer, this card starts with the magic. Where my Transcend Class 10 card would only allow me to shoot 2 shots per three seconds once I reached the buffer, the Extreme Pro allows me to shoot 2 shots per second when I run over the buffer. It also replenishes the buffer in about 4 seconds versus the 15-20 seconds the standard Class 10 cards would take.
So, this card may or may not be for you. If you shoot event photography, sports photography, or weddings, then I would suggest you buy a couple or more of these. If you are a casual shooter who never fires off a large burst of photos, I would save your money and buy a less expensive card like the Transcend 16 GB Class 10 SDHC Flash Memory Card TS16GSDHC10E that is one third the cost.
In the video I compare three cards, the Dane-Elec 8 GB Class 4 SDHC Flash Memory Card DA-SD-8192-R, the Transcend 16 GB Class 10 SDHC Flash Memory Card TS16GSDHC10E, and the SanDisk Flash 16 GB SDHC Flash Memory Card SDSDXP1-016G (Black). I start by shooting straight RAW photos until the camera's buffer is exhausted and then see how quickly the card can write to clear the buffer. I then shoot the cards again in Fine JPG mode. I do this to show that the three cards will all suffice if you are just shooting JPGs. I wanted to show this so that it would help others in deciding if this was worth spending three times as much as other Class 10 cards. Since the 8gb and 32 gb Extreme Pro are built to the same standard and architecture, the write/read performance should be the same and the capacity should be the only difference. As this is a SanDisk branded SDHC card, this is a rather safe assumption.
Overall, I would buy this card again.
-Cheers!

Fast UHS Class 1 SD Card, March 12, 2011
This review is from: SanDisk Extreme Pro 16 GB SDHC Flash Memory Card SDSDXP1-016G (Personal Computers)
Introduced on January 17, 2011, the SanDisk Extreme Pro is the fastest SD card to date. At 45MB/s (45 Megabytes per second, read *and* write), this card is 1.5x faster than its predecessor, the SanDisk Extreme [ 8GB, 16GB, 32GB], which is rated 30MB/s (class 10). Like its predecessor, the SanDisk Extreme Pro comes in storage capacities of 8GB, 16GB, and 32GB.
- UHS Speed Class 1
This SD card is rated UHS Class 1 (commonly denoted as UHS-I or UHS-1). The UHS-I speed class rating was introduced by the SD Association in June 2010, and should not be confused with the older speed class rating that designates a memory card as class 2, class 4, class 6, and class 10 (for write speeds of at least 2 MB/s, 4 MB/s, 6 MB/s, and 10 MB/s, respectively). Memory cards that are rated UHS-I support data transfer speeds of up to 104 MB/s.
As an aside, on January 5, 2011, the SD Association announced yet another speed class rating -- UHS Class 2 (UHS-II or UHS-2) -- for memory cards that support data transfer speeds of up to 312 MB/s.
- Compatibility
This SD card is backwards compatible with any device that supports SDHC (SD, High Capacity) and SDXC (SD, Extended Capacity). SDHC cards are memory cards that have capacities that range from 4GB to 32GB (FAT 32 file system). SDXC cards are memory cards that have capacities that range from 64GB to 2TB (exFAT file system).
I have no trouble using this card on my older devices, such as my Canon Rebel XSi (introduced in January 2008), HP iPAQ 111 (introduced in September 2007), and a generic memory card reader.
- Performance
A faster speed rating does not mean faster performance. To take full advantage of the 45 MB/s speed, you will need a device that supports the new UHS bus interface (the Nikon D7000 is currently the only such device that I know of).
My rebel XSi is, not surprisingly, unable to take advantage of the UHS bus interface. I ran some tests to see how the SanDisk Extreme Pro stacked up to each of my class 4, class 6, and class 10 SD cards by noting the time it took the Rebel to write data from its buffer to each of the SD cards.
The results:
Class 4: ~9 sec (Kingston)
Class 6: ~10 sec (Transcend)
Class 10: ~6 sec (RiData)
UHS Class 1: ~6 sec (SanDisk Extreme Pro)
Conclusion:
There is no appreciable performance gain beyond Class 10 because at speeds upwards of Class 10 (i.e. >10 MB/s), the bottleneck lies with the speed at which my camera is capable of writing data from its buffer to the memory card.
---
To recap: although the SanDisk Extreme Pro is backwards compatible with devices that support SDHC cards, you will only be able benefit from the its 45MB/s read/write speed if your device is able to take advantage of the new UHS bus interface. Regardless, the SanDisk Extreme Pro is definitely worth considering as a means of "future proofing" your memory cards. Moreover, as of this writing, the SanDisk Extreme Pro 8GB, 16GB, and 32 GB cards are actually priced near or below prices for their SanDisk Extreme (30 MB/s) counterparts! Highly recommended.
