I guess that's better than buying 4x 512GB micro sdcards to juggle around, trying to remember which game was on which exact card or where you might have lost one.
But in that moment you relived the joys of game cartridges :D
Or PS1/PS2-era memory cards. Cartridges are easy since they're labelled, but is my Final Fantasy save on my red or blue memory card?
Or those third-party memory cards that had multiple "pages" that could be switched via a tactile button. "I know it's on here somewhere."
The SSD is much faster too; though only a few games benifit (SD card is still fast).
The SSD itself might be, but the Deck can't read off them enough faster to make a huge difference.
I had not heard that? It should be able to fully utilise PCIe Gen 3 x4 NVMe drives that are increadably fast. This will be night and day with the best SD card in many common computing tasks. However is often hidden in games (many expecting to load off snails pace optical discs) where they are only sequentially accessing a few GB whilst showing their publisher's logo anyway.
