SanDisk 256GB Ultra Luxe, USB 3.2 Gen 1 Flash Drive up to 400MB/s Sold by Amazon

Seems like a decent price

Look on the right hand side 'Other Sellers on Amazon' and you'll see dispatched and sold by Amazon, 4p more but at least easier returns/refund if issues

As pointed out by sifer69 this Flash Drive seems to be 3.1 not 3.2 and averages speeds of around 150 MB/s not the 400 MB's on the product page headline
