munz Posted September 21, 2009 Share Posted September 21, 2009 I just received my replacement 16GB Voyager GT as my original 4GB Voyager GT had died, and although the read speeds are comparable (~29MB/s), it seems the 16GB version only writes at a disappointing ~9MB/s as compared to well over 25MB/s for the (discontinued) 4GB variant. Those are the speeds out of the box, so I'm still using FAT32 with my current system specs under Windows 7 x64, is the 16GB really so much slower than the 4GB version or am I doing something wrong (ie: need to reformat it)? Thanks Also I do use large files >4GB so would formatting to NTFS be detrimental to performance? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted September 21, 2009 Corsair Employee Share Posted September 21, 2009 Try to format the drive with the SD-CARD Organization. format utility and then run HD-Bench software to test the performance. Link to comment Share on other sites More sharing options...
munz Posted September 21, 2009 Author Share Posted September 21, 2009 thanks ramguy, i've downloaded the software from here and used the settings "Full (Erase ON)" and Format Type Adjustment "OFF" are those the correct settings? i've got the free version of HD tach which had a read speed of about 29.2MB/s, will retest and repost once the format has completed.

munz Posted September 22, 2009 Author Share Posted September 22, 2009 upon completion of the format, the file transfer speed is hovering around ~15mb/s. i've attached the hd-bench test results. overall i've seen an improvement of ~6mb/s but it's still far from the 4GB GT's +25mb/s write speeds. is this normal for the 16GB GT? http://img33.imageshack.us/img33/5880/hdbench.jpg Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted September 23, 2009 Corsair Employee Share Posted September 23, 2009 Speeds are slightly slower than we would expect. Your 4GBGT will be faster since it used SLC technology but cannot on Flash drives any bigger than 8GB for what I can remember. In this case your Flash drive is now MLC which can be slightly slower.
