This week, we discussed file systems and disk defragmentation. It was an eye-opener to learn that FAT32, the older file system, had a max capacity of 4GB and is mainly used for USB flash drives.
Now we have advanced to NTFS, the default file system for modern Windows devices, which is used for Windows drives, enterprise environments, and large or mission-critical storage. NTFS has such a large file limit that it is considered theoretical in size. However, I did find a claim from Wikipedia that the maximum implemented file size is 9 (PB).
Next, we reviewed disk defragmentation. Disk defragmentation takes chunks of files that are scattered across a Hard Disk Drive and consolidates them to improve performance. Disk defragmentation is only necessary for Hard Disk Drives. Solid Disk Drives use a process called TRIM.
I recommend that readers learn about file systems and drive optimization to maintain performance across all drives and reduce HDD workload.
