Which SSD for me?!

 Which SSD to buy?!

 You want to balance speed, TBW, warranty, price, &c., weighed to your specific needs.

 SPEED: check the maximum data transfer rates, but also the IOPS 4K read and write specs.

 TBW: A quality SSD has at least a TBW = 600 X its own TB size, but the longest lasting ones have a much higher TBW.

 CACHE: Check the DDR and SLC caches, compare the cached vs. non-cached speeds.

 CONTROLLER: I prefer mine with 8 channels or more, but that is a personal preference. That and other controller specs, notably the
 clock speed affect the overall SSD performance. Some PCI-E 4.0 or higher SSD controllers clock at 1+ GHz, which is why you should use
 an NVMe M.2 2280 heatsink to maximize performance. There is little downside in spending $10-30 for an SSD heatsink that will last you
 as long as the M.2 2280 format will. Otherwise the SSD can be slowed down by its Thermal Throttling, which kicks in when a certain
 internal temperature is reached.

 SSD CELL TYPE:
 SLC (1 bit/cell) are extremely rare, and the most expensive, but have the highest TBW/SSD size, and only need DDR cache.
 MLC (2 bit/cell) are still available, but at insanely high prices. Very high TBW/size and fast write speeds w/o SLC cache.
 TLC (3 bit/cell) are the obvious choice, of course, they are also the most widely manufactured ones.
 QLC (4 bit/cell) have the lowest TBW/size, and are much less popular than TLC ones, which is great news.

If the price doesn't matter and you want the absolute best, then SLC or MLC, otherwise TLC are your choice, unless you get an extremely good deal on a QLC SSD, and a low TBW is not an issue for you.

 WARRANTY: most quality SSD have 5 years warranty, but there are still good ones with only 3 or even 2 years.

 Verify the manufacturer's specs with reviews, tests, and other sources of information (geizhals.eu, ssd.userbenchmark.com, &c.)

 Also search information about general technical issues that arise is certain SSD model lines. They can happen to any brand.

 NOTE: A quality SSD doesn't "die" when it reaches its TBW, you can still use it, but you should not fill it up anymore,
 leave 10 to 20% of it free of data.
