X32UseR,

Once I had downloaded and installed hotfix KB934428 from Microsoft site I had no problem reading and writing to SDHC cards, namely Transcend Class 6 8Gb and 16Gb cards. The maximum speed attained when writing to the card was 3684.4 kbytes/s, and 5530 kbytes/s copying from the card to the 1.8" hard-drive.
Best regards,
V

Its similarly slow in Linux. Does the job though.

You should be able to get much faster transfer with an external USB SDHC reader, if needed.

Really? I would think the internal reader would be faster.

Really? I would think the internal reader would be faster.

I'm using a transcend TS16GSDHC6-S5W (S5W is the bundled USB reader) and get 15..20MB/s read and 13..18MB/s write using opensolaris/ZFS. Don't know about the internal sd reader as it is not supported yet.

ZFS caches the write ops to get as much 128k full blocks as possible and flushes it in 5s at most, if I'm not mistaken. That optimizes the write speed even if you have a batch of small files.
