    Very Slow After 20% or so Written

    I bought this drive in December 2022 when it was on sale, but I didn't have a computer with NVME support until April 2023. I installed this drive into my new laptop, and starting moving video footage files to it planning to edit them during a business trip. I slowed down by a lot after about 400GB or so written into the drive. I was on a tight schedule for travel so I left the file transfer (total 2TB)over night to complete. 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.

    Best value 4tb nvme ssd

    Worth the price and probably the first 4tb ssd I would recommend somebody. The speeds are amazing I downloaded in rdr2 in 20-30 minutes. One problem is the ease of use as at least in my case there was no partitions made therefore didn’t show up on file explorer ect

    Perfect for gaming

    With the price finally being low enough to snag, this drive is perfect for any PC. With plenty of storage for games with room for more. The speeds match that of Western Digital (which I used before this) and as long as there's a heatsink, the temps stay perfect. Definetly recommend this to anyone looking for a large capacity NVME drive.
