According to official spec, Arista 7050QX-32 has 4GB RAM and up to 4GB flash storage. In the market most of the switches have 2GB flash storage. Unfortunately the one I got has only 1GB flash storage. When I called Arista support, they told me I could not upgrade the storage module by myself and they don't have the module available in the market.
However when I was running diagnostic commands I found the flash storage is a STEC USB device. So I think probably I could replace the original 1GB USB flash with standard 4GB USB drive.
Thanks @Foray , he showed me the picture of the inside of the switch. In order to double confirm the size and connector type, I also opened chassis and found it's USB DOM w/ standard 9PIN connector.

So I ordered an 4GB USB DOM from local market.
Here is its spec.
Swap the flash storage is pretty straightforward.
1. First, backup your EOS image, boot-config, startup-config and your configuration file.
2. Remove the upper cover. (You don't need to remove PSU.)
3. Swap the USB DOM.
4. Close the cover and power it on.
5. Follow the steps in the post Roll back SONiC to EOS on Arista 7050QX-32 and recover the EOS and config.
