Based on capacity and rate of compression, tape drives work at different speeds.
For Raid 5 all the hard drives have to be of the same speed.
The most common range is 5400-7200 rpm. There are also 10000 and 15000 rpm drives. Solid state drives do not operate on the same principals as disk drives, and do not spin at all.
Packaging tape is a little bit more stronger than duct tape.
As long as it's duct tape. Duck Tape has several different kinds of tape.
A device, like a tape recorder, that reads data from and writes it onto a tape. Tape drives have data capacities of anywhere from a few hundred kilobytes to several gigabytes. Their transfer speeds also vary considerably. Fast tape drives can transfer as much as 20MB (megabytes) per second. The disadvantage of tape drives is that they are sequential-access devices, which means that to read any particular block of data, you need to read all the preceding blocks. This makes them much too slow for general-purpose storage operations. However, they are the least expensive media for making backups.

A variable frequency drive (VFD) refers to AC drives only and a variable speed drive (VSD) refers to either AC Drives or DC Drives. VFD's vary the speed of an AC motor by varying the frequency to the motor. VSD's referring to DC motors vary the speed by varying the voltage to the motor.
no they not have the same speed
Transportable Non - Volatile Reliable
they all have the same speed
The speed of all sounds is the same in the same medium.
Nope, there are lots of different kinds
In reference to your PC; RAM, CD, DVD, Floppy Disks, Hard Disk Drives, Flash Drives... Any device from which you can retrieve the last byte stored at any time without having to read any other data stored prior to it. Tape Drives are not Random Access. In order to reach the last byte stored on the tape, you must read all the bytes stored before it.
