Pros: Love Sony products. this one does what i wanted and quickly and with little noise. Sure at the speed you hear some whipping of the air inside, but nothing else - Great Drive for a PC to load OS and other software.
Summary: Be sure to notice that this is the bare drive, so it does not come with SATA cables for power and data. This would be a good replacement drive, or if you're building a computer, but be sure that your power supply or motherboard comes with the necessary SATA cables like mine did.
