If you are familiar with tinkering and tweaking with your PC, you likely already know what RAMDISK (also known as RAM drive) is. Or at least you have an idea. In which case, most of what this article says is not new to you. If you don’t, this article will inform you about RAMDISK, how it works, what benefits it adds to smartphones, and which Android phones to look for.
What is RAMDISK?
RAMDisk is a segment or portion of system memory on your PC or Android phone that is used as a disk drive. In essence, it is a virtual storage, created by software, from your device’s RAM chip.
How does RAMDisk work?
Your Android phone or PC has two types of memories – RAM and storage. RAM is for running apps, while storage memory is self-explanatory: it is used for storing files. The thing is that RAM is a much faster type of memory (which explains in part why it is so expensive and comes in smaller chunks than storage memory).
RAMDisk or RAM Drive is created by apportioning a part of your gadget’s RAM as a hard drive. The concept of RAMDisk on Android phones is new because we now have large capacity LPDDR5 RAM chips available. Starting from this year, 16GB RAM chips are now in production. Some of that capacity can be portioned into RAM Drive for use during intense gaming or other high intensity activity like video and graphics editing.
What are the Benefits of RAMDISK on Android phones?
The key benefit of having RAMDisk is that it boosts the performance of the particular app or game you are using per time. As already mentioned above, RAM is much faster than storage memory. By using a part of your device’s RAM as a hard drive, you experience much faster performance. This is because your Android phone is able to read and write to the disk much faster.
So, smartphone gamers, as well as people who do video/graphics editing on their cell phones, can now enjoy a boost in performance while using those apps.
As an example, an LPDDR5 RAM chip is about 25 times faster than a UFS 3.1 internal storage disk. Imagine the performance boost to be experienced from using a portion of that RAM chip as virtual storage.
Which Android Phones have RAMDisk?
Xiaomi is the first cell phone manufacturer to introduce RAMDisk technology for smartphones. The first phone to be so equipped is Xiaomi Mi 10 Ultra. This is a 2020 model with a 16GB LPDDR5 RAM chip. The company has introduced a RAMDisk Trial Mode for users to experience the benefits of a RAM Drive on the phone.
For now, the Mi 10 Ultra is the only smartphone with RAMDisk. However, this is expected to catch on, as more and more cell phone manufacturers are producing gaming-centric smartphones. At the very worst, we will see more Xiaomi phones with RAMDisk in the near future.
