As you'd expect since this is a PlayStation-licensed product, it works well with the PS5. The advertised speed is 7000 MB/s, though my PS5 told me that it operated at 6560 MB/s. That's still blazing fast, and I imagine that number might fluctuate up and down. For those reviews that said the PS5 didn't recognize the SSD, they might've been unlucky with static discharge or a manufacturing defect. Either way, it looks like WD is eager to make those issues right, so there should be no concerns about buying this.
I also bought this because WD is an American company, and I'm trying to avoid buying electronics like this from overseas manufacturers.
