When first installed, it was loaded with over 3.5TB of data from an external USB 3.1 hard drive. The lack of DRAM cache soon became obvious. There developed a regular cycle where file transfer was paused when the drive became saturated. Crucial supplies a driver / utility that will improve performance but be prepared for halts if you are writing large amounts of data continuously, especially as the drive nears maximum capacity.
Saying that, it performs well for its intended purpose as a "write once / read many" drive.

But if you're coming off of booting from a regular HDD on an old computer, then yes it is excellent.
My business trip got extended when I was not in the country to 3 months. I came back to the US in late August and wanted to find out why this drive slowed down so far. I tested with CrystalDiskMark (CDM) with all default settings and I got around 3000MB/s read and write sometimes. I realized this drive is probably designed to have good result with the default 1GB file size test. So I tested with 64GB file size and only sequential to save time. I consistantly get around 80MB/s write speed, and 2000MB/s read speed. The bottleneck is around 8GB.
So I backed up everything to other drives, emptied this drive, and run CDM on empty drive, I got adverstised speed. I keep copying files to the drive until it slows down, which happens around 20% capacity used, and run CDM with 64GB test, same 80MB/s write speed.
I contacted Crucial support, and they claim this is how the drive should perform. I can get a replacement. But since it's not an individual issue, getting a replacement means nothing. The email chain has been going back and forth since September. Crucial told me to update firmware, perform optimizing steps, and I did all of them, yet same result.
I have other QLC drives, Included test results on intel 660p and 665p. When they have more ratio of space written, I can still get faster than mechanical drive sequential write speed, around 180MB/s.
If you plan to write more than 8GB of data to this drive at once at some point, do not buy this drive. It's not an unrealistic situation. Let's say you use this drive in your laptop, with OS, some software and documents. It's easily exceeding 20% of the drive capacity. Now you want to copy photos from your camera SD card to this drive, good luck. I hope you never take more than 8GB of photos.
