Fantastic storage and never had a problem with it...
4 Stars
Fantastic storage and never had a problem with it...
I've had a lot of various type of storage devices, but the "Crucial 4TB" is one of the best I have had so far. I already own 5 of these and I have not had a problem since I started using them.These devices are very solid and I have not had a problem with stability nor storage. They are super light weight and very easy to fit in any compartment of a backpack, case, or other form of carry-on. I been able to store music, videos, and zip/rar files without a problem. Reading and writing files back-and-forth have not been an issue at all, especially if you use it to store videos and music, and you want to hear and play back video/audio files directly from the storage device.There's no worry about stability, I have been using these devices for over 2 years now and have never had one give me read issues. (Although I do constantly do defrags and checks regularly so that usually helps)There are a few concerns you will need to know when you order these...1.) Although read/write are very stable, I have never had one that reads faster than 50+ Mb/s2.) This device is not ideal for copying tons of 5Kb-100Kb files, it's very slow to write when it comes to several thousand image or text files (Or similar files of similar size), I was copying over several image files I have stored and it took hours to copy over. Large size (500 Mb - 30 Gb) files copy over quickly and easily, but several small size files (5Kb or less to 100Kb) took forever. Keep this in mind if you need to move tons of image or text files or several thousand other small-size files3.) It's best to also order extra USB-C codes as the cord that comes with the device is only about 3 inches long. Plus, both ends of the cord are USB-C. So unless you have a USB-C reader, you might wanted to order some extra codes for it. You can usually get a pack of 3 for about $5-$10.4.) When it comes to listening to music or watching a movie, I have never had a problem with either file types when it comes to reading the files. However, do not watch a movie or listen to music while files are being transferred as it will interfere with the read/write speeds. Plus, doing so will interfere with the video and audio files and will cause your video and audio files to skip or momentarily stop playing as files are being transferred.Other than what is mentioned, I have not had a real serious issues with the storage devices. Keep doing defrags every so often and they will always work great.
