To be USB 2.0 or USB 3.0… That is the Question

SandraNet on September 26, 2017

What may be one of the most frustrating things when connecting new “Plug-n-Play” equipment with USB cables, is the difficulties faced upon connecting them… and they neither Plug… nor play (Insert primal scream here). Frustration tends to mount while moving a file from one drive to another and it is doing so, seemingly at a snail’s pace.

We at Sandra Network would like to help with this BEFORE you are forwarded from phone extension to phone extension, continent to continent, waiting on hold for the answer that may be right there in the clear blue! (You will see what I did there… in a moment, and laugh… just wait)

One common issue is the age of the equipment, be it a keyboard/mouse/ flash drive, external drive or printer, they all may cause the same frustrations. It is all about speed, and the simple way to tell (if you no longer have the box with the description, or the “Read me” file) is the color of the connector or the icon next to the connector on the computer.

USB 3.0 is the third major version of the Universal Serial Bus (USB) standard for connecting computers and electronic devices. USB 3.0 is usually distinguishable from USB 2.0 by blue color-coding of the ports and plugs, and by the initials “SS”.

USB 2.0	USB 3.0
480 Mbps (Megabits per second)	4.8 Gbps (Giga bits per second)
Can either send or receive data, i.e. copy or paste	Can simultaneously send and receive data, i.e. copy and paste

Overall:

If you want seamless speed as an option in transferring data,
If something you plugged in as a new device is not properly connecting or is giving USB errors
If there is the option of USB 2.0 or USB 3.0 on the computer.
check to see what color the port is, that choice can make all of the difference in speed or connectivity

Why do I need more than one backup?

“My IT Company is crazy! They want me to have multiple backups… I use my flash drive nightly, and am ok.”

“I know I have backups, someone set it up years ago and it runs automatically… I think.”

“What, you should test your backups?”

Yes, backing up can be a pain, but unless you are willing to use all your hard work, or memories, it might be worth it. If your home or office burns down, what will you be able to retrieve if you don’t have multiple backups.

Types of data to backup:

System State:

This is a copy of the configuration of your machine. In the event of failure, sometimes the COST of rebuilding the machine and the programs is the most expensive element.

Data:

This is your documents, pictures, music libraries and company data. One should always create multiple backups for such data.

Application based backup:

Many applications have their own backup, and for restoration purposes, need the backup in their proprietary format in order to restore the data. If this is the case with the applications, you should run the application-specific backup, and then backup the data file set it produces on another medium.

Types of backups (Media)

USB Drive:

Great for second copies of data and system state and data. Do realize that after the USB Devices fall from the top of the cabinet once, they can mechanically stop working and become DOA. Not a good place for your only backup, and definitely not a good place for original files and music libraries!

Tape Drives

These have been in service for years, and still work. Unfortunately, they do rely on complicated restores of data, and offsite storage. Nothing says failure when your backup tapes are on top of the server you are backing up. Very expensive fire | storm | water victim when the tapes are ruined with the server they are backing up. Can be very expensive for both tapes and tape drives.
