Incompatibility issue with Kingston Technology 8GB microSDHC memory card and video file playback. ASIN: B001CQT0X4 SDC4/8GB
I recently purchased a Kingston Technology 8GB microSDHC card from Amazon.com for my 8gig Sansa Fuze (firmware version 1.01.15). I formatted the card while it was plugged into my Fuze via Windows XP. Loaded some songs and a video file to the ext memory card.
During playback the video was jerky then lockup within a minute, requiring the fuse to be reset. Music however seemed to playback (although i didn’t concentrate on testing music files). I worked with Amazon to replace the card with another Kingston 8GB card and had the same exact issue.
I copied the 48MB video file to the internal memory - plays back smooth, no issues. works 100%
Copied the same video to a sansdisk 512Mb microSDHC card (ext) - plays back smooth, no issues. works 100%
Copied the same video to the Kingston external microSDHC - jerky playback, then locks up, requiring a hard reset.
Copied the file back to the computer from the Kingston card and checked the file with a byte for byte compare, its the same as the original file. No data corruption.
There appears to be a compatibility issue with the Kingston memory card. I purchased this card thinking it was a class 4 memory and for a decent price. But it’s not working out. EDIT:( Due to the incompatibility issue i’ve returned the Kingston 8GB card)
Some other observations: Transfer speeds… Copying the Video file size = 51,085,894 Bytes
Sansa Fuze Internal Fuze memory External Kingston 8GB
Read Speed 17 seconds 15 seconds
write Speed 9 seconds 140 seconds**
** was extremely slow writing data to the Kingston 8GB microSDHC
Video file used was a 8 minute music video I personally converted using Sansa’s Media Converter (v 1.0B004.236CDG) software. Avenged Sevenfold - A little piece of heaven. I also tryed other files that have the same issue.
The Kingston memory card says it is microSDHC compatible with version 2.0 specs of the standard.
