Words is (non-)wisdom(tm):
Many wearleveling optimisations from the linux side will not (fully) work with encrypted fs or encrypted partitions, e.g. TRIM.
Hint 1: Go for a drive with a high TBW / drive-writes count. Hint 2: overprovisioning (leaving free non-partitioned space) helps. Hint 3: Warranty: 10 years cost (extra) money, 5 years is good sense, 3 years is (very) low.
It could be that a MLC drive wins out against TLC one.

Do not go below 240 GB, as the value per money is (much) worse below that.
In the enterprise (datacenter) class I've had little to no problem with the Samsung and Intel drives of the last 3 years, but time will tell - as warranty begins to run out on some of them now. Early Intel was uneven.
In the professional (desktop/soho-server) class (10 years warranty), well, no drop out on any drives mounted since 2012, but, see above, time will tell, all on warranty still.
In the semi-pro (desktop/soho-server) class (5 years warranty), about 5 per 1000 dropout rate before end-of-warranty (time or TBW reached), seams to be spread all over the manufactureres and the products.
In the (IMHO) home-use-only class (less than 5 years warranty, less than 60 Drives-writes TBW), it's a very mixed bag, some charges are very good, but the ones before and after could be crap (same manufacturer, same product).
*shrugs* You get wat you pay for. 20 bucks more for a drive with 5 years instead of a 3 year warranty is simply good sense and better sleep. About the same as the tires on your car.
