Block Size vs. Cluster Size

[Support]

To get the best read performance, the Block Size of FancyCache is recommended to be equal to or less than the cluster size of the file system.

This applies to
1) the FancyCache Volume Edition,
2) the FancyCache Disk Edition if the drive is SSD and was partitioned under Win7.

And in the NEW version of FancyCache (0.5.0) it tells you what the cluster size is next to the volume/disk.

thank you, magic-man

Yes, the Volume Edition shows the cluster size, while Disk Edition not. Because there might be multiple volumes with different cluster size in one disk.

Now the problem is that if the block size is too small, the additional memory allocated will be large. In the next version, we'll try to improve the read performance when block size is larger than the cluster size. But anyway, for read performance, it is always the best when block size is not larger than the cluster size.

Thanks for this. I had been using 16k (or the 'default 32) thinking that may be too small.. only to find out it's 4k, now using this and hoping for even better performance! Thanks.
