1) He's overwritten the entire drive 8 times in 33 days. That's not a "consumer" workload.
2) 177 isn't a percentage. It's how often it's had to overwrite the data. 8 times. Which matches the data written.
3) Samsung claims 2,000 P/E cycles (the number represented in SMART 177). Independent testing has shown closer to 6,000 P/E cycles. That means that it's at .25% of its claimed and documented life cycle, being overwritten every 4 days for over a month. If he wasn't okay with replacing the drive after 500 days or a year and a half, then he should have researched better, or bought the next size up in drive capacity, which would have cut the wear in half. It's more likely, though that the drive will last around 5 years, even under these write loads, according to independent testing by anandtech and others.
If you don't understand what SMART is, does, or means, please don't talk about it as though you do. Other people might see your confident ignorance and believe you instead of doing their own research.
