Any disadvantages to using block size higher than the disks?

Post by audisputnik1 »

I know it is recommended to use a block size that is equivalent or lower than the disk's block size, but is there any disadvantages to using higher than the disks? I was using 32kb for my game drive but somehow, the Windows Store/Xbox App won't let me install that drive anymore unless it is 4kb. I can take the hit of the RAM overhead by using 4kb block size, but I'd rather not and use that RAM for write cache instead.

The sequential read/write performance might not be the best when the cache block size is larger than the file system cluster size. However, because large cache block size will reduce CPU utilization, in some computers 32KB~64KB might be the best one.
