We used a Kingston 1 GB Data-Traveler Flash Drive and performed the following tests with every available format: However, flash memory has a limit when it comes to how often a memory location can be changed and therefore, Journaling doesn’t seem to be the first choice when it comes to Flash-Drives.

If your computer stops because of a power failure or some other issue, Mac OS X uses the journal to recover the hard disk to the last acceptable state before it stopped. If journaling is turned on for a disk, Mac OS X maintains a continuous record of changes to files on the disk. Since the storage efficiency of Mac OS Extended format typically applies to 1 GB or larger volumes, Flash Drives with a capacity below 1 GB may still benefit from the MAC OS Standard format.MAC OS Standard a.k.a HFS on the other hand does not support file names > 31 chars, it does not support additional meta-information used by Mac OS X, has as limit of 65k allocation blocks, and is more error-prone than HFS+.However, Mac OS Extended format optimizes the storage capacity of large hard disks by decreasing the minimum size of a single file. Mac OS Extended format is a hard disk format that increases the number of allocation blocks on the disk and also allows more than 65,000 files on the hard disk.HFS+ seems to have a lot of advantages over MAC OS Standard a.k.a HFS. But how do all these formats compare and which one should be used, if Macs running OS X are the only computers the Flash-Drive will ever be used with? The same is true for UNIX, which makes UNIX-FS the obvious, best choice. If the flash drive needs to be used on a Windows PC as well, then MS-DOS FAT32 File System is the one and only option available. MAC OS Extended (Case-sensitive, Journaled)Īnd the best format to chose really depends on the intended use of the drive.When formatting a USB Flash Drive (or any drive for that matter) OS X offers the following 7 choices: Putting everything on a USB Flash Drives may be a good solution but I’m just exploring the possibility while I’m writing this, so let’s see how it goes.

Currently, the password tool ( Pastor) and the data file are located on my Power Mac G5, which of course is a problem when I need to lookup a password when away from the G5, like at work for instance. all RC4-encrypted and password-protected.

Open the Launchpad and select Other > Disk Utility to open Disk Utility.Since a while back, I’m using a tool to store all my passwords, website logins, program serial numbers etc. That allows you to preserve any existing data.ġ. With the GUID Partition Map, you can non-destructively convert an HFS+ drive or partition (except for older Time Machine drives). Convert Drives and Partitions to APFS (Non-Destructive) It’s a good idea to stick with the older file system unless you set up a new Time Machine drive. But if you have an older Time Machine drive in the HFS+ format, you can’t convert it to APFS without losing data. Important: Time Machine supports APFS starting macOS Big Sur. Depending on the existing file system and partition scheme, you may also be able to convert a drive or partition to APFS without losing any formatting. Don’t get too caught up in the other options unless you prefer an encrypted or case-sensitive file system. While erasing a drive or partition, selecting APFS should suffice.
Disk Utility supports the following APFS formatting options:
