Get maximum Read Write speed from internal hard disk data drive/volume/partition

To get maximum read-write speed from Internal hard Disk partition you need to Format it with “NTFS” File system and set “Allocation unit size” to 16-64 Kilobytes.

By default allocation unit size is 4KB.

Increasing the Allocation unit size makes it much easier to manage storage space but it also causes wastage of storage space.

So if you worry about wastage of storage space then use Allocation unit size as 16 KB.I recommend using 16 KB as Allocation unit size.

Otherwise you could use highest 64 KB.

Note : Formatting the Internal hard Disk partition will Erase all the data in it.

The internal hard disk in your computer may have multiple partitions. This technique should only be used in  drive/volume/partition which will be used to store users data. Don’t use this tweak in Boot partitions in which Windows OS has been installed.

  • As you can see below that internal hard disk has multiple partitions named ( C: E: G: H: I: )
  • Out of them C: and E: partition has Windows OS installed. The user should not use this tweak in these partitions.
  • G: H: and I: partition is used to store users data. So we can use this tweak on it.

  • Now you will get better Read Write speed from this newly formatted partition.
  • Similarly, format other data partition as shown above. Don’t forget to backup the data in the partition before formatting it.
