Your RAM is faster than any SSD or NVMe drive. So why not use it like a hard drive?
A RAM disk is a portion of your memory allocated to act as a virtual drive. It’s volatile storage—meaning it’s wiped after reboot—but ideal for temporary files, caches, or editing software.
Why Use a RAM Disk?
-
Drastically reduce read/write times
-
Speed up operations in programs like Photoshop or Premiere
-
Reduce wear on your SSD by offloading temporary storage
-
Ideal for compiling code, running portable apps, or extracting archives
Requirements
-
At least 8GB RAM (16GB+ recommended)
-
Windows PC
-
ImDisk Toolkit or SoftPerfect RAM Disk software
How to Set Up a RAM Disk with ImDisk
-
Download and install ImDisk Toolkit
-
Open “RamDisk Configuration”
-
Choose size (e.g., 1GB or 4GB depending on your available RAM)
-
Assign a drive letter (e.g., R:)
-
File system: NTFS (for Windows compatibility)
-
Optionally create a persistent image file to save contents between boots
Once created, you’ll see a new drive in File Explorer—blazing fast and ready to use.
Use Cases
-
Set browser cache directory to the RAM disk
-
Use it as Photoshop scratch disk
-
Store temp video exports or intermediary render files
-
Compile code faster by setting your build folder here
How Much Faster Is It?
On a typical system:
-
RAM Disk Read Speed: ~5000 MB/s
-
NVMe SSD Read Speed: ~3000 MB/s
-
SATA SSD Read Speed: ~500 MB/s
Your system’s responsiveness during cache-heavy tasks will noticeably improve.
Caveats
-
Data is lost on reboot unless you save an image
-
Don’t store important files unless backed up
-
Not ideal for large file transfers or permanent storage
RAM disks are a hidden gem for power users. Once you try it, you may wonder why Windows doesn’t offer it natively.
