I've only had it a few days - I've copied a few files onto it and it can read them so I can't say how it will perform 6 months after currently. There was more than 62 gigabytes free on 64 GB, which seems reasonable compared to other drives. I wish it had a label on it to indicate it's 64 gigabytes or USB 3 - it's just black with a few stripes. The lid is very tight - it may bother someone, it suits me.
