Great hard drive. Acceptable price for 2TB. I have 3 WD portable drives. They all work well and a few have lasted several years. The difference between this and Ultra lies in the backup software. I do not need that. I needed a good external drive for PS4 and this one works well. But you need to reformat it for FAT or exFAT. PS4 does not recognize NTFS file system. These portable devices are great. I prefer them over traditional external hard drives. No need for an external power supply. It gets all of its power from the USB port. This drive is USB 3.0. The performance is pretty good. Seems to support read and write speeds of 100MB/s and up depending on file size. When transferring large files, the speed can drop to 50-60 MB/s. This disc is as small as it gets and not very heavy. This is a good choice if you need external storage. I trust Western Digital. Based on years of experience with their products. I don't trust any other brand more than WD. I had serious problems with their drives.
