    @saturnotaku 850 Pro has been around since 2014, and both are SATA SSDs. Whether getting a new-with-warranty fancy drive is worth sacrificing half the capacity is one's personal choice; I'm simply informing of the alternative.

    Well, a few tips:

    For SSDs, I wouldn't recommend a capacity that low, from any vendor. #! reason for that being tied to warranty, which most SSD vendors peg against the TBW rating of the drive. The smaller the SSD, the shorter the rated TBW is, and the higher the chance of losing everything should the warranty cover not go through if you've exceeded the TBW (which is always the case).

    Next: NVMe SSDs to avoid at all costs: The Intel 600p, the aforementioned WD Black and the Plextor M8Pe (both versions apply). At that rate, you'd be better off with a higher capacity SATA III SSD than a more expensive and under performing NVMe SSD.

    I gather that the Toshiba RD400 line has improved over time, so I cannot speak of them yet until I have hands on a sample for testing.

    The second note is strictly tied to the Samsung SSDs. Unless otherwise noted, the consumer drives tend to have the Magician Toolkit made available to them, and warranty is often covered either by Samsung or/and the reseller. For the OEM bare drive variants (such as the SM951 series), they're often targeted at OEMs and will not have the Magician Maintenance software available to them. However, they're often cheaper to purchase than their consumer oriented counterparts, albeit with limited warranty cover (if any).

    As always, consider your workload and budget allocation carefully before splurging money on NVMe SSDs. The sweet spot is now at the 512 GB mark.

    For the Evo and Pro Samsung lines, it all comes down to the endurance rating and expected longevity. The Pro, as implied, also has nearly double the warranty coverage, but in terms of performance, both lines tend to level out at higher capacities. For instance, the 960 Evo and Pro 1 TB drives perform nearly identically.

    Extra notes on NVMe drives and day to day usage:

    (a). Note that NVMe drives run much, much warmer than their SATA - based M.2 counterparts. As such, on some consumer-grade NVMe drives such as the notorious Plextor M8Pe 1 TB NVMe drive and the older Samsung 950 Evo and Pro SSD lines, you may experience thermal throttling somewhat. If possible, invest in a silicon-based thermal pad or stick to the Samsung 960 Evo and pro lines. The latter drives have an excellent heat sink assembly that keeps the NVMe SSD cool, even under sustained load(s).

    (b). If you run Linux, do NOT mount the filesystems on an NVMe SSD with the discard option. This is strongly discouraged, and isn't even necessary on NVMe drives.

    Here in India the SSD prices are outrageous, we pay the rate of Samsung 950 pro 256GB for a Samsung 850EVO 250GB. I hope you get the idea. Even I use 256GB SSDs on my PC and hell its expensive.
    On Linux by default Discard option isn't added on NVMe on newer kernels 4.8 and above. I need to check fstab file for more details since I was on older 4.4 kernel, presently using 4.13 kernel.
    Indeed NVMe M.2 run hotter than SATA drives of same form factor. Almost 10C higher than m.2 SATA.

    I've noticed a lot of systems come with thermal padding included if NVMe drives are not already installed.

    I'm sure some mobile systems have good thermal designs and can take good advantage of thermal padding, but most fail miserably at cooling an M.2 SSD when it's needed to be used at it's highest performance levels (sustained...).

    Capacity is important to get the most sustained performance from any SSD's available today except Optane based models. This is achieved by OP'ing (33% recommended).

    Warranty doesn't play a part in my purchase decisions of any storage subsystem. I may return a storage component if it fails while testing with none of mine or my client's DATA on it. But I will never return a storage subsystem component that I've put any DATA on.

    In either case; Warranty doesn't cover your DATA. It only covers the drive.

    Prices are relative to where you live... unless you can get a cheaper sample brought by someone from 'outside'. That doesn't mean that a lower quality/capacity should be settled for (if not settling is an option...). Especially when prices are so high in your area is when I would save longer to get the better/best option. Longevity of a quality item is cheaper in the long term than the alternative. ;)
