[QUOTE="RonD, post: 1088637, member: 117536"] to beat this thread to death, a few more comments, I divide "disks" into 3 main groups 1. HDD (Hard Disk Drive). Normal drives in use for years with 1 or more spinning platters. HDD can be internal using a SATA interface. They can be external using a USB interface but are really the same HDD. The USB interface adds some overhead so they typically use a bit more CPU horsepower and may be a little slower. 2. SSD (Solid State Disk Drive). Use flash memory for storage with special control logic to provide a high speed replacement for HDD. Can be used as the main "Windows Drive" with higher performance. The flash memory causes 2 problems. You need to do an erase before you can do a write. The control logic tries to optimize the erase/write performance, but writes of lots small files can cause performance problems. Flash also has an "endurance" wearout problem if you erase/write the same flash location many times, so the controller tries to spread writes over the entire flash memory to avoid hot spots. Most SDD are internal with SATA/mSATA interfaces. There are some external USB SSDs, for example the following, I did not know about these until I started looking.

Thumb/Stick USB drives. Also use flash memory for storage but typically have slower write performance than SSDs. I view these as a 2014 version of a floppy drive. A good way copy files between computers that do not have an easy network connection. [/QUOTE]
