Hey everyone,
I’ve been using a sandisk extreme portable SSD with my macbook setup for a few months now, and I’m hitting a wall that I’m hoping someone here has navigated before. Most of my daily workflow involves using capcut mac to process 4K footage directly from the external drive to save on internal storage. Initially, the speeds were blazing fast, but lately, I’ve noticed the drive getting incredibly hot—almost too hot to touch—about halfway through a long export.
When the heat kicks in, the write speeds seem to tank, and I start getting “Disk Not Ejected Properly” errors or the app just hangs entirely. I’m currently formatted to exFAT for cross-platform flexibility, but I’m wondering if switching to APFS would handle the metadata-heavy nature of video project files better? Or is this purely a thermal throttling issue with the SanDisk enclosure itself?
I’ve also seen some weird behavior where the Mac doesn’t recognize the drive after a crash until I do a full system reboot. Is anyone else seeing these kinds of stability issues when pushing their portable SSDs with heavy video rendering? I’d love to know if there are specific macOS settings or firmware updates I might have missed that could help stabilize the connection during high-load sessions.
