Super Media Store has the A-DATA Turbo Series 8GB Class 10 SDHC Card for $22 - $3 off with coupon code ADA8GHSE [Exp 6/6] = $19 with free shipping. Supports transfer rates of up to 23MB/s on devices supporting SD v.3.0 and is backwards compatible with SD v.2.0.
#2 if the device supports SDHC then the Class 10 with SD 3.0 will work as its backwards compatible. Unless the device does not support the size of the card.
Sure as hell beats those class 2's they were trying to sell earlier this week. 23Mb/s is impressive....
Class 10 does not work in many camcorders...do your homework before you buy.
The RiData 16GB Class 10 SDHC worked in my Pentax K20D before any update, even though Pentax released a firmware update for newer sizes/speeds.
#2 if the device supports SDHC then the Class 10 with SD 3.0 will work as its backwards compatible. Unless the device does not support the size of the card.
Thats the devices problem, not the cards.
Do your homework.
