SanDisk Extreme Pro 16GB  Best High Speed Disk For HD Cameras
592555
I have been relying on SanDisk's Extreme Pro SDHC cards for over two years.  I use a 32GB and a 16GB Extreme Pro for my professional HD video camera (panasonic hmc 150) and I get nothing but a crisp, clear picture every time.  I have never encountered any problems with these high speed disks.  They've never froze up or failed to upload or offload.  They are tough and rugged.  I suggest these great cards to any professional photographer or videographer.  They will not let you down.

I have used San Disk SD cards for my photography and videos that i shoot using my Canon 70D and they have always proved to be reliable and trouble free.  This one is no exception and to me it is well worth the price you pay for a solid product

Item: SanDisk Extreme 32 GB SDHC Class 10 UHS-1 Flash Memory Card 80MB/s (SDSDXS-032G-X46)

I love SanDisk memory cards. I mainly only use SanDisk cards in my DSLRs (T3i, 5D) and in a Panasonic prosumer camcorder. They work flawlessly, and they are quick to write data and are ready when I'm ready to record again. There's no wait time for me for my uses.  Depending on what you actually want to do, the card matters. I have been using this card at softball games to grab 4 continuous  shots of batters swinging.  No issues there. I used the card to record videos up to 3 minutes long on my DSLR.  I used the card to record videos 30 minutes long on my Panasonic camcorder during weddings. It's worked perfectly for me for my uses.

Using a Kingston USB 3.0 Card reader, I experienced these transfer speeds for 5.2 GB for 13 videos from a DSLR:
over USB 2 port: 2 minutes 45 seconds.
over USB 3 port: 2 minutes
It depends on what types of files you are writing, the total size, and the total number.

I bought two of these SanDisk Extreme Pro SD cards based on past use of SanDisk SD cards and the new claimed speed of 45MB/s; which should make them 1/3rd faster than SanDisk Extreme III SD cards at 30MB/s.

However, I have found both cards are actually slower on both write/read speeds than SanDisk Extreme III.  And the Extreme Pro average w/r (15.7 MB/s) is barely faster than Ultra II average w/r (14.1 MB/s)

Using AJA System Test:
Extreme Pro ~ write= 13.5 MB/s & read= 17.8 MB/s (card #1)
Extreme Pro ~ write= 13.9 MB/s & read= 17.7 MB/s (card #2)
Extreme III ~ write= 15.4 MB/s & read= 19.0 MB/s
Ultra II ~ write= 9.7 MB/s & read= 18.5 MB/s

I am wondering if these SanDisk cards are actually SanDisk cards or knockoffs?

VERY Fast - hands-down SanDisk makes the best flash drives available,  Noticeably faster than other brands that claim USB 3.0 speed, SanDisk drives provide True USB 3.0 throughput. I own two SanDisk USB 3.0 drives (my other is a 16G) - I bought my first SanDisk USB drive many years ago. I also own several SanDisk Micro SD cards. In my professional opinion (been a computer programmer and Admin for 15 years) and  experience SanDisk USB Drives and SD Cards offer superior performance, speed, and the build quality is outstanding - I've yet to have one go bad, break, or have any problems. I wouldn't recommend any other brand - don't cheap out just to save $5 you'll regret it later.

I definitely recommend this product and SanDisk as a brand

I now have a few of these SanDisk Extreme SD cards and I am completely satisfied. They are fast and reliable.

With the SanDisk Ultra I see a slight 1/2 second delay when taking normal photos at 12MP. At high speed (constant shooting) I have to wait a number of seconds for the photos to be processed and displayed. On the other hand, I do not see a delay when using one of these Extreme SD cards for normal photos. At high speed, it's a blink of an eye before they are all processed and displayed. I only shoot at 12MP most of the time, but some times speed is important.

All in all, great purchase - good product. I have a nice selection of SanDisk thumb drives as well as a flavor of SanDisk memory cards.

SanDisk is still the best with cheap price vs good quality. Take note it doesn't come with HDD mount, It's a must buy product!

My new Corsair USB 2 16GB Flash Voyager Drive is the best! I use it to transfer and store my high-definition photos. I couldn't be happier with the quality and price from Amazon.com!. It's fast and I haven't lost a bit of data. I highly recommend it. I love this, I am able to take everything with me rather than drag the computer along. A bargain.

This card is fast, reliable and a great deal. I've been shooting digital photo's for years now and shoot video for a living, and I've never had a problem with SanDisk Extreme cards. If your data matters to you, buy one of these. And no, I don't work for SanDisk.

Have been using SanDisk products for over 15 years and never the first problem with any of them. This latest purchase, the SanDisk 64 GB Ultra memory card, is just right for all of my applications. After grabbing an hour-long, full HD video on my Nikon CoolPix camera, captured at 30 frames per second @ 1920 x 1080 pixels, there remained another 20 minutes of video storage remaining available! Am very satisfied with the price and performance of this memory card, no need to spend extra money on the "Extreme Pro" version, in my estimation. SanDisk has earned my loyalty over the years.

I recently purchased this Sandisk compactflash to use with my Sony DSLR.  The camera has a burst mode (continuous picture taking) and this card was able to store multiple high quality pictures due to the high speed read/write capabilities, about 2-3 pictures per second.  For a 10.2 megapixel camera set to standard quality I am able to take around 500 pictures on this 2GB card.  I highly recommend for any DSLR.

I use this card for 1080p on my Canon DSLR.  The camera's buffer never backs up, indicating this card is FAST. I have used Sandisk cards for several years and have never had a problem.  (I can't say the same for cheaper cards)  Your SDHD card is equivilant to film.  Did you buy bargain film and have it developed at the cheapest place in town?  If not, why would you buy a cheap SDHD card.  This card came in a box with a coupon for a free 1-year subscription for RescuePRO. (recovers data from erased and damaged cards) You can not go wrong buying a Sandisk card!

Fast digital media, reputable brand, decent price. What more could you ask for?
If you want to speed up your burst mode and the time it takes your camera to render video, go for Extreme.

Is SanDisk better than another name brand? I cannot say. I picked this based on MB/S speed and price.

NOTE: In my opinion, 16GB is the minimum you should buy these days, but given the small price differential, you should probably bump up to a larger size.

The drive is very fast, and seems to be a better value than CF cards from SanDisk and Lexar.  In my testing, it reached around 130MB/S read and 100MB/S write, which I consider very close to the specifications.  I highly recommend it, it works flawlessly with my card reader and Canon 5D Mark II.

This high capacity card is very fast and has what seems like unlimited storage. Even if you are recording video it will allow a full 8+ hours of HD recording time. It has 45mb write speed which isn't the fastest but if you are just shooting stills than this card will work just fine. Overall I love this card and would recommend it to anyone.

I've used this in my D7000 and GX1 bodies.

In the GX1 it registers room for over 13 hours of video at 1080p at the highest quality.  (?!)

It writes reasonably fast in either body--seems about as fast at my PNY Pro-Elite 35MB/s 32gb cards.

In my Sandisk USB3 reader I get about 40-45MB/s write and 45-50MB/s read.  This is slightly faster down and slightly slower up than the aforementioned PNY cards.

All around, this is a great deal!  It's fast enough, and as big a card as you can get right now.  It's bigger than the SSD I use for my OS!  And the price continues to drop from the already reasonable dollar per gigabyte I paid.  I plan to get a couple more!
