Yes, the information on both can be changed.
Solid state Flash drives USB Hard disks drives
Secondary hard drives, usb flash drives, removable hard drives, cd, dvd, zip disks, floppy disks, mini discs, ect.
These are all types of secondary storage devices.
Drives that show up under Hard Disks must be identified as a fixed disk, but flash disks generally show up as removable, so you won't see them under the Hard Disk category.

No. Floppy disks have the lowest storage capacity of any mainstream storage device. Hard drives, CDs, DVDs, and Flash drives all hold far more data than a standard floppy disk. Even when they first came out, hard drives and tape reels held more data (though they also cost far more).
Yes. Data can be stored to removable media such as flash drives, Floppy Disks, Cd's and DVD's.
Hard drive disks, Flash drives, Cd's, Floppy disks and etc., can hold files so long as they are not bigger than the space of storage on the device.
Floppy disks are rarely used today, mainly due to the fact that they are obsolete. Flash drives, hard disk drives, and memory cards all take the role of floppy disks in a more simple fashion.
Secondary Storage
There are many brands and makes of hard disks from many manufacturers, so there are new hard drives coming out all the time which make incremental improvements over older generations of hard drives. The newest most fundamentally different kind of hard drives are called SSD drives, which do not use any disks at all, and work the same way that USB Flash Drives and the memory cards in Digital Cameras work. See... http://en.wikipedia.org/wiki/Solid-state_drive
This means that have an SSD (Solid State Drive) hard disk. These hard disks uses "nand flash" technology, is the same as Pen Drives. The major difference between common hard disks, and SSD is the low power consumption, faster access times, but unfortunately they are more expensive, and have less capacity. k
