Obligatory reminder that this is QLC, which, as a general rule, is the slowest and least reliable type of flash available today. It works fine and performs well for typical light/moderate usage, but if you dump a huge amount of data to it over a short period of time it will fall to 100mb/sec.
Therefore do NOT buy this if you plan to:
A. Write heavily to it constantly.
or
B. Ever fill it it up most/all of the way.
Otherwise, price per GB is pretty good, the caching and other tricks will make it run quite fast in normal usage, and a 5 year warranty is nice (but keep in mind that's a hardware warranty, and doesn't cover your data).

Edit: Also note, it has been down to $229.99 within the last month, so it might drop again if patient.

Are there instances where this will operate slower than a good SATA ssd?

This is great info. Also this type of ssd expected to fall to $160-200 sometime this year (8 to 10 cents a MB)

it has 24gb SLC buffer so it's a considerable amount of burst writing you'd need to do.

<280 gb of SLC total>

Yeah when consecutively writing files greater than the cache buffer of the drive (varies with size and make of the drive, but usually between 20gb and 50gb mark for qlc drives as a general rule), the sustained write speed actually dips below the write speeds for fastest sata hard drives.

According to UserBench, other TLC products with few more bucks, same capacity, and same protocol have 10~30% higher performance. And of course, much better warranty.

For sure QLC is a relatively new technology, and manufacturers didn't overcome the downsides QLC have yet. Cautiously consider purchasing it when you're a heavy user. I purchased HP EX920 instead.

Very few people would likely write 400TB within 5 years unless using it for video production or database or backups or something.

BUT a few common data points for comparison (note, some of these are SATA):
860 EVO 2TB - 5 Years, 1200 TBW
960 EVO 2TB - 3 Years, 400 TBW
970 EVO 2TB - 5 Years, 1200 TBW
MX500 2TB - 5 Years, 700 TBW
WD Blue 3D 2TB - 5 Years, 500 TBW
WD Black SN750 2TB - 5 Years, 1200 TBW

Don't even worry about it.

Effectively, 400 TBW means you can write 400 TB to the drive before you should worry about running out of write/erase cycles. Per Anandtech, a consumer will typically write less than 10 GiB per day to the drive [anandtech.com]. If you have 400 TB of writes to the drive, that's 400,000 gigabytes, which means you will hit that limit in about 40,000 days, or 109 years.

The controller of the drive is likely to fail before the flash does.

It's a strong "maybe," and not for faint of heart. You'd need to research the specific MacBook Pro model (year) and investigate the use of an adapter, etc.

80% (perhaps 95%) of users will not know the difference in daily PC usages. It has a large SLC buffer that is more than enough. At 50% user data, it has more than 100GB of SLC. And at the least I. E. 75% or more full, the 2 TB 660p has 24GB. So if you need space, and the SSD performance, no other SSD in the market will beat this!
