Nintendo Switch allows players to enjoy games via cartridges, digital internal storage and digital storage on SD cards. While all three methods lead to the exact same content, a Twitter test by SanDisk Japan reveals some surprising load-speed differences.

The video in the tweet below is sectioned off into four quadrants. The top left is a game cartridge, the top right is a SanDisk Extreme MicroSD, the bottom left is a SanDisk Extreme Pro MicroSD and the system’s internal memory is on the bottom right. Predictably or not, internal memory loads fastest, followed by the Pro, Extreme and the cartridge in last place.

From our counts, the Switch internal is able to load the Breath Of The Wild title screen nearly two seconds before the Pro comes in. A half-second later, the standard Extreme pops into frame. All told, a Switch cart apparently loads content three or four seconds behind the rest.

Obviously this tweet is meant to sell SanDisk’s high-end MicroSD cards, but its findings are interesting nonetheless. To us, it’s surprising just how fast the Switch’s internal memory is. Its 32GB may not offer much in terms of space, but at least the quality seems to make up for it.

Above all else, this video should better inform Switch owners about how to install their games. Especially if you’re swapping digital content between MicroSD and internal, it’s clear that you should always install the game that demands the best performance on internal memory first. Two extra seconds to get to a title screen may not seem like a big deal, but, when it comes to streaming gameplay quickly, that advantage can potentially make all the difference in framerate.

If you’re interested, the SanDisk cards used in the test cost about $73 for a 128GB Extreme Pro and $68 for a 128GB Extreme. There’s obviously a premium associated with those prices considering standard and highly-rated 128GB cards from SanDisk and others cost a mere $40.

Nintendo Switch is available now for $299.
