Issue with Direct Compile from Flash drive with exFAT |

Hello All,
I recently purchased a new flash drive because my old one with NTFS was starting to fail CRC.
I never had any problems editing directly off the drive and saving the compilation there.
so for my new flash drive, which is the exact same model (Corsair Vega 64G), I decided to format using exFAT because it is supposed to minimize read/writes to the drive and extend usable life.
Problem is, the new drive with exFAT completely hangs when using CCS compiler read/writes during compiling. I mean, it must hang for like 20-25 seconds before it completes.
But get this -- the drive works normally for general transfer of files back and forth through the USB port.
So I reformatted the new drive back to NTFS and it is lightning fast like the old one.
Anyone have any ideas on this?
Thanks,
Dave |

Help if you told us what OS. The behaviour has changed with different OS's.
ExFAT is normally between perhaps 10 & 50% slower for general I/O than NTFS. Faster though for many reads, and when handling large files like video.
However one thing is that ExFAT defaults to, is a very large cluster size. 128KB for your drive, versus 4KB for NTFS. If the code in CCS triggers cluster based I/O for small transactions, it'll perform very badly with ExFAT. |

I think you hit the nail on the head.
This is with win7x64
The new drive came formatted to exFAT 128k, and I had formatted the old one to NTFS 4k.
I will try this out on another drive and post the results, unless someone can verify this.
ANYONE USING A FLASH DRIVE TAKE NOTE.
Thanks. |
