SD Benchmark: SanDisk Extreme HD Video 30MB/s 16GB SDHC Class 10 Memory Card (SDSDRX3-016G-A21)

Our very first review!

Today we'll benchmark the SanDisk Extreme HD Video 30MB/s 16GB SDHC Class 10 Memory Card (SDSDRX3-016G-A21)

Things to take away:
  • SanDisk - a reliable brand
  • Extreme - SanDisk's mid-high tier series of cards
  • HD Video - says it can do 1080P "full video"
  • 30MB/s - SanDisk boasts a performance of a minimum of 30mb/s sequential read and write
  • Class 10 - the card will perform at a minimum of 10mb/s sequential write (yes, a little redundant)
  • SDHC - Secure Digital High Capacity, SDHC cards vary in size between 4GB and 32GB
Testing Hardware / Software:
  • Rosewill USB 3.0 Card Reader
  • Gigabyte Z68MA-D2H-B3 - using the USB 3.0 Port
  • Windows 7 x64
  • ATTO Disk Benchmark (testing from 512kb to 8mb)
  • CrystalDiskMark x64 (testing 5 x 100MB)
Results:


ATTO Disk Benchmark
  • From around 128kb and up to 8mb, the card performs roughly @ 44.5MB/s read, and 36MB/s write
CrystalDiskMark x64
  • Sequentially, the card does around 45MB/s read and 36MB/s write
Not bad for a "30MB/s" card!

Conclusion:
  • Street value on this card has dropped.  I imagine it will drop even further since it is "discontinued" for the new Extreme 45MB/s Series. 
  • If you could obtain this card at a decent price, it will easily outperform other brand/off brands as the Extreme Series of SanDisk tend to be overperforming
A "normal" 16GB SDHC Class 10 card will cost around ~$13-18.
A "decent" brand would cost even more.
This SanDisk Extreme HD Video 30MB/s 16GB could be purchased for around ~$25.  Is it worth it to you?
Other brand's SDHC Class 10 may or may not perform admirably.  Remember that Class 10 means "minimum sequential write of 10MB/s".  By getting this Extreme HD Video 30MB/s, you are virtually guaranteed (with the right hardware) at least 30MB/s write. 
Remember that USB 2.0 Card Readers typically max out at around ~20MB/s, read or write.

As of 4/9/2012 - Price Ratio of 16gb SD = $1.56 per gigabyte for this card, with 35MB/s write
Compare to other 16gb SD Cards, with $0.90 per gigabyte, @ 12MB/s write. 
Is the price differential worth it to you?  Would you pay extra for faster speed, or a larger card?
The choice is yours!

HIGHLY RECOMMENDED (4.5 out of 5)
