Stop Letting Temporary Files Wear Out Your Drive
Browsers, installers and editors write thousands of short-lived files to your disk and then throw them away. On an SSD that is needless wear, and on a hard drive it adds fragmentation and slowdowns. SoftPerfect RAM Disk gives those files somewhere better to go: a virtual drive stored entirely in your computer's memory.
Quick facts
- Version: 26.10
- Platforms: Windows, macOS and Linux, on Intel, AMD and ARM64 processors
- Licence: free, fully featured 30-day trial, then you buy it
- Installers: Windows installer, macOS installer, and DEB and RPM packages for Linux
Key features
A disk that lives in RAM and shows up like any other drive
The program creates a virtual disk in memory that appears in Windows Explorer and other applications. You can save anything temporary to it and it is far faster than a physical drive.
Send Windows temp files to memory
You can configure the operating system to use the RAM disk for temporary files, so the system and most applications write their short-lived data there. That spares your hard disk from excessive reading and writing.
As many RAM disks as you have memory and drive letters for
You can create any number of virtual disks, limited by the memory available. In practice that means up to 26, because of the number of drive letters. On 64-bit systems with Intel, AMD and ARM64 processors the disk size is not capped.
Keep your data between sessions with disk images
You can work with on-disk images, and RAM disks can be tied to an image file so the contents are preserved between sessions. Smart sync is part of the persistent-disk feature.
Temporary sensitive data that disappears on restart
A normal RAM disk is completely erased when the computer is turned off or restarted. That makes it a handy place for sensitive scratch data.
Who it's for
It suits you if you have spare memory and want to move browser cache, build output or temporary files off your SSD or HDD. IT professionals can also find it useful.
Pros and cons
- Pro: far less fragmentation, because temporary files never reach the disk.
- Pro: works on Windows, macOS and Linux.
- Pro: a full 30-day trial before you pay.
- Con: a non-persistent RAM disk loses its contents on restart, so you must use an image-backed disk for anything you want to keep.
- Con: every gigabyte you give the RAM disk is memory your applications can't use.
FAQs
Will the data survive a reboot?
Not on a standard RAM disk. If you associate the disk with an on-disk image file, the data is preserved between sessions.
How many RAM disks can I create?
As many as your memory allows, up to 26 because of drive letters.
Can I try it first?
Yes. There is a free, fully featured 30-day trial.
Does it run on Apple silicon or ARM?
The supported platforms are Intel, AMD and ARM64.
