SAMSUNG 970 PRO M.2 2280 1TB PCIe Gen3. X4, NVMe 1.3 64L V-NAND 2-bit MLC Internal Solid State Drive (SSD) MZ-V7P1T0BW

Pros: I upgraded from an 850 PRO. The difference in terms of raw throughput are not noticeable in my use-cases, the real benefit for me is that this uses NVMe (instead of AHCI over SATA) which allows me to multitask multiple "large" file operations without them causing each other to slow down, or sometimes even completely halt, until the previous task completes.

This alone greatly improves my productivity as it eliminates a system bottleneck. Note however, this could be solved by much less expensive PCIe SSDs.

That said, I specifically chose this SSD because it's the only (non-enterprise) device left using MLC. This is important to me because it means I can rely on sustained and consistent performance when I need to move hundreds of GB worth of data around, which is common in my workloads. For the average person I would say this is not needed and in fact provides negligible performance for the majority of consumer workloads.

Being my first time installing an M.2 card, this was super easy to install. Like, installing RAM level of easy.

Samsung's software made it very quick and painless to clone/transfer all my data. It's literally just a few mouse clicks, a small bit of waiting, and you're done.

Cons: Although sequential speeds are through the roof, in day to day usage it isn't really useful to me.
Random speeds and latency are still dominated by Intel Optane, but I couldn't justify the price of getting the 905P.

For "older" systems like mine that were on the forefront and just on the verge of M.2 slots becoming mainstream, you might have a bit of a hassle getting your motherboard to accept this as a boot drive. I had to physically disconnect all my other drives before it finally gave me the option and then it tried to revert back when I reconnected them.
For modern systems you shouldn't have any problems, though results will likely vary per board/manufacturer.

Overall Review: If you're looking for an SSD for gaming or general office use, I would just get the cheapest PCIe NVM SSD and call it a day, you likely won't notice any performance difference in day-to-day use. This device and most others are a waste of money unless you have a real use that justifies the massive price difference (for me it's work related to photo/videography, and sometimes SQL databases)

Pros: IT'S FAST. I just love this drive. I use my computer for editing video, photo's and playing World of Warcraft. I would say that its the fastest SSD drive I have ever owned. Windows 10 boots in seconds and I don't have to wait for any program not even graphic intensive ones.

Cons: The drive worked great for 2 years and then out of the blue I started getting blue screens. I was backing up my files to a 12TB external drive and it started crashed my computer. it shuts down the computer so fast that I had to video the error message just to see what it said "WHEA_UNCORRECTABLE_ERROR" looked this up online and its a SSD failure. at first it was random around every 20 min or so. I was able to remove my files from the drive, but now its maybe every 5 minutes and its random. when it crashes the computer it takes me to the computer BIOS and the drive will not show up. Hard restart the computer and the drive is back. At first I thought it might be one of my other hard drives I have 3 on this pc. I unplugged them one my one and it keep happening. Then I unplugged the graphics card "a 1070ti" and plugged the video onto the onboard video and the same thing happened. I have a backup SSD drive with windows 10 loaded onto it and what I'm typing this review with. Same hardware just booted from a different drive and I am not having a problem. hope this helps you all out.

Overall Review: Its a great Drive!
Its FAST!
It has a 5 year warranty. other then the headache I think it will be RMA by Samsung.
Would I buy it again? YES!
