    • Tiny, amazing storage size
This 4tb external SSD was about 60% more expensive than comparable external HDs, but it offers a free really key advantages. It's very tiny. I looked at the pictures, but I still didn't get just how tiny it actually is. I love that it takes up virtually no space and can be easily transported in a pocket. You could put it in that little pocket in your jeans. It doesn't need a separate power cord. This is actually my favorite feature. One less cord on my desk it always a great deal. It's much faster than an external HD. I'm connecting to an older iMac, which only has USB 2, but if I ever connect it to my laptop I'll be able to take advantage of USB-C speeds. Compared to an HD, it also doesn't have to spin up, which takes my previous western digital HD up to v 10 seconds, so I'm still seeing a nice speed boost. There are bigger, faster SSDs, but I will take the small speed hit for the size advantage. I did not have to format for Mac, as some reviewers said. Mine came in exfat, which is compatible between both. SSDs are much more reliable than HDs, in both longevity and shock resistance. This SSD is small enough to easily transport, which means you have to consider dropping it (or stopping whatever bag it's in). SSDs withstand about 50x more shock than HDs (~1500g vs ~30g). It's quieter and uses less power than an HD. ... show more

    • Reformatted NTFS for faster transfer rate
Update 8-9-23 Read this whole review... Reformatting this drive as NTFS improved the transfer rate. I bought the Crucial X6 a few months ago. I read the reviews, and some people were disappointed about the transfer rate. Out of the box, the transfer rate was horrible on my Windows 10 laptop. The max was 112 kbps. I updated the firmware, and that did not improve the transfer rate. I reformatted the drive NTFS on a Windows 10 PC and the transfer rate went up to 338 Mbps. Much better, and that was possibly limited by the HDD that was reading files. I just got 2 more X6 drives with the same issue, and the same format to NTFS fix worked (for a Windows PC). So, if your X6 drive doesn't work as expected right out of the box, try reformatting it. Also, remember that there are many places for bottlenecks to slow things down (like the computer, the USB connection speed, and the drive from which it is reading or to which it is writing). ... show more

    • Very portable large amount of storage for a great price
Love how small this is. Works great and so far has performed incredibly well for us. Plug and Play makes installation a breeze. Being from a brand like Crucial, I have no worries of data loss or corruption. I have used without issue for months now and would highly recommend to others as an IT professional. ... show more

    • Don't spend your money
I bought this 4TB Crucial solid state drive to replace a 4TB Seagate spinning hard drive. I was happy to see a Black Friday price of just $150, and that was an insta-purchase for me. Small, fast, capacious, and pretty cheap! Well, it's cheap for a reason: it dramatically slows down write speeds if transferring 10GB or more at a time. When I got the drive, I ran a Blackmagic Disk Speed Test on the drive: 1425 MB/s write, 727 MB/s read. That's pretty solid! I transferred all the content from my 4TB Seagate to my new Crucial drive. It took about 6 hours for 2.5TB of data to transfer. Once it was done, I moved about 20GB of data from another drive, and that's when I noticed it was really slow all of a sudden. After the transfer finished, I ran Blackmagic again, and with a 5GB test, the drive had write speeds of about 700 MB/s for the first two tests, but by the third, it was down to 50 MB/s, I tested my 4TB Seagate spinning hard drive, and it was 150 MB/s after three 5GB tests. My spinning hard drive was 3x faster writing data than my solid state drive! I thought maybe the computer might be indexing the Crucial drive, so I let it sit for three days. Same issue when I tested again. So I thought maybe macOS doesn't like exFat, and I erased the drive, formatted as APFS, and transferred the 2.5TB again. It's been about 24 hours since the transfer finished, and the Crucial drive still slows to just 50 MB/s write speed after 10GB of transferred data. I'm inclined to think this is just how Crucial made this drive, as it is super repeatable, with various formats, and various tests (I also tried 3GB and 1GB tests - once it gets to about 10GBs of transferred data, it slows to about 50 MB/s.) I only have one other external SSD, a Samsung T7. Running the same test, it consistently has write speeds of 400 MB/s after 10GB of transferred data. I don't know why the Crucial drive is so slow for large transfers. I was so happy when I got it and ran the first test, and got 1400 MB/s write speeds. And honestly, I'd be happy if it could sustain 400 MB/s write speeds. But being 1/3 the speed of a spinning hard drive? That's just embarrassing, and unacceptable. This drive is getting returned, and I'm going to stick with Samsung. ... show more
