Modded Switch is super slow + SD card testing ~4 MiB/s (fake/failing?)
I bought a modded Switch Lite off Facebook Marketplace and I’m trying to figure out what’s causing it to be so slow. System menus load slow, games take like 1–3+ minutes to load (it gets past the switch loading screen fast, but takes a long time to get to the title screen of the game/load into gameplay), Luigi’s Mansion elevator transitions can take a couple minutes, and occasional random lag/stutters in games.
I ran an SD card benchmark on hekate and it shows like 3–4 MiB/s, and chatgpt told me its insanely low.
I tried testing with H2testw and it could only test on 78gb of my ~400gb used space. I aborted it immediately and the .h2w test file kept coming back after i deleted it when i clicked out of the sd card drive.
Windows shows 476GB usable (its a 512gb card so idk if thats normal) and only one normal partition though.
It came with a SanDisk Ultra 512GB, formatted as exFAT, and it’s running Atmosphere. it says the version is 1.0 | AMS 1.7.1_lsp | E ,but i have no idea what _lsp means and if thats okay. I'm the third owner of this console now, so idk whats been done to it. all the games and everything were there when i bought it
Not sure if this is a dying SD card, a fake card, or something wrong with the mod setup (emuMMC etc.)
Lmk what you guys think is the problem, if theres any tests I should run because right now i'm troubleshooting with chatgpt, and recommendations for the best sd card to get next if that's the issue. Thanks in advance!
