Average Reviews:
(More customer reviews)The labeling of this item (SanDisk 16GB Ultra II SDHC card) is very confusing. On the front side it claims a maximum speed of 15MB/sec. At the same time, it is marketed as 'Class-4' (which means a minimum read/write speed of just 4MB/s). To move up to a 'class-6' card from the same manufacturer, you have to buy the SanDisk 16gb Extreme III SDHC card which costs 2-3 times more.
I decided to take a chance with this Ultra II card, even though my new Canon EOS Rebel T1i explicitly requires a 'Class-6' card for video capture. I'm happy to report that the card is fast enough to keep up with my camera, even in burst mode and in 1080 HD video mode.
My own benchmark (see 'Customer Images') revealed that the read speed of this card is consistently fast at 18-19MB/s. But its write speed is strongly dependent on the data file size:
- For small files of 1MB each, the card is only able to write at about 6MB/s. That means it qualifies as a borderline 'class-6'.
- For typical photo files (4-6MB each), the write speed is much faster at around 10MB/s.
- When writing a huge file of 1GB, the card can actually achieve the claimed maximum speed of 15MB/s.
The SanDisk Ultra II may not be a good choice if you want to use it as a ReadyBoost device (frequent writing of smaller file). But when used in digital cameras, this 'class-2' card is just as fast or even faster than other brands of 'class-6' cards (such as the Transcend 16 GB SDHC Class 6, which levels off at 11MB/s for large files). This makes the Ultra II a great value - especially for those people who prefer to stay with a trusted name brand.
