150x SD card vs class 6 SDHC SD card - speed comparison.

My impression is that my old 150x card is faster that the new class 6 SDHC card. Is there any way to verify if my impression is true? 150X card is rated for 22MB/s max read speed. Class 6 SDHC card is rated for minimum 6MB/s _write_ speed. The ratings between these two are apples and oranges, but in general you will not find a fast 8GB SD card that is inexpensive because to get 8GB capacity at low cost they're using MLC flash chips which are inherantly slower (versus SLC at any point/production in time). Beyond this, the two cards might (if the 4GB is SD not SDHC) use different addressing methods - your PDA may not have equal performance with both even _IF_ they happened to arbitrarily have the exact same performance in a card reader connected to a PC for a speed test. The Transcend 4GB is among the fastest cards available at a reasonable price, so it's no surprise another would be same or slower, BTW. For such a speed test a prior poster linked to the Flash Memory Toolkit, in some circles it is a popular windows application to use. Other alternatives might include Sisoft Sandra, Atto ( http://www.techpowerup.com/downloads/123/mirrors.php ), or many other disk benchmark programs. |
