Post NTFS-3G performance vs Paragon's NTFS for Mac
Previously, I was using NTFS-3G (april 2008 release) with MacFUSE for NTFS read / write operations. However, it was sooo terrible slow that I couldn't bare it anymore as I use external USB storage for multiple VM images.

Having removed NTFS-3G (using the uninstall script), rebooted, install Paragon's NTFS for Mac, rebooted...and now all my external USB NTFS read / write operations are flying again! Reading a 2.1GB file from the 2.5inch USB drive only took 77 seconds with the average transfer rate around 28-29 MB/s...something that I couldn't achieve with NTFS-3G.

I didn't change anything other than the NTFS driver. Still using the same Macbook, same OS X 10.5.2, same usb drive, same partition, same USB port on the Macbook, same cable.

So, question is, why is NTFS-3G so slow? Or is it MacFUSE?

Sorry, I can't guess what release you mean by "april 2008 release". There are many packages made by several developers for OS X.

The most typical problem is not using the right package and device. I get over 30 MB/sec with external USB and over 60 MB/sec with internal SATA disks on Linux. The OS X values (if the driver and the device are used correctly) are reported to be lower by only a few MB/sec.

Ah, sorry, it's the 1.2310 release that was released in March but I didn't download and install it until April...got the dates confused.

Downloaded the DMG package.

The performance release is the UBLIO DMG.

Thanks, but I've read that UBLIO is labeled as experimental. Is there any stable release with caching enabled out there?

It was indeed experimental a year ago but we are not aware of any problems for a long time.

Perfect!! So it's safe to say that it's pretty stable then?
