Jun 1, Flash Memory for Camcorders: Lightweight, Fast and Powerful!



Flash memory for camcorders has revolutionized the camera industry by making it easy to have smaller
more portable camcorders and digital cameras that give you more power and reliability than ever
before…!

Here’s what you need to know about this digital camera storage media…!


What Is Flash Memory?

What is flash memory?

Flash memory is the most popular form of digital camera storage media today. It was first developed by Toshiba in the early 1980’s from EEPROM
(Electrically Erasable Programmable Read-Only Memory) technology.

What’s in a Name?

The name “Flash” was suggested because the data stored in the device
is erased by using a sudden “flash” of electricity reminding the
inventors of the flash  of a camera!

So … What exactly is it…? Flash
memory is high-density electronic memory (in the form of memory cells) that are
stored on solid-state devices such as:

  • Memory
    cards and sticks
  • USB
    flash drives
  • Solid-state
    drives (SSD)

Flash
memory is non-volatile meaning: The data will not be lost when the device has no
power. It
can be erased and reprogrammed at will.

Camcorder
flash memory is mainly used for storage and transfer of data and is very
popular because of it’s…

  • Fast
    read/write access times
  • Data
    compressibility (you can fit a lot of data in a little space)
  • Physical compactness (thin small cards or sticks)
    and…
  • Durability
    of its solid-state storage mediums.

What Are Some of the Advantages of Using Flash Memory?

The advantages of flash memory

One
of the many advantages of using flash memory for
camcorders is that it involves no  moving
parts…

Unlike other digital storage media such as…

 Hard drives … Which use a mechanical arm that reads and writes to a rapidly revolving disc… Or…  DVDs or Mini DVDs  … The DVD is a solid-state medium but the camcorder must use an intricate disc drive and a precise laser system to Read/Write  to it.


Some Other Advantages of Using This Type of Memory…

The advantages of flash memory

Some of the advantages of using flash memory are…

Advantages of flash memory #1
  • Flash memory is light, durable and quiet. Again. All electronic, no moving parts, such as in a hard drive.


Advantages of flash memory #2
  • It uses much less power than hard drives and disk drives and is less likely to be affected by shocks, dust, temperature, high pressure, out to two, moisture, etc.


Advantages of flash memory #3
  • Another reason that flash memory for camcorders is so attractive to both consumers and camera makers is that the endurance cycle ratings (how many times that you can read/write to the media) is very good. It is somewhere around 100,000 cycles before the integrity of the storage unit begins to deteriorate.


Advantages of flash memory #4
  • Data stored in flash memory will have about 10 years or more of shelf storage life.


Advantages of flash memory #5
  • It is also easy to have an extra supply of the small, lightweight flash memory cards or sticks. When you fill a memory card with video footage, you can always take out the full one, quickly pop an empty card into your camera or camcorder and continue shooting!


Flash Memory for Camcorders… The Drawbacks…

The Disadvantages of flash memory

Some
of the only drawbacks with flash memory cards or sticks are..
.

Disadvantages of flash memory #1
  • The “cost per megabyte” ratio is still higher than hard drives.


Disadvantages of flash memory #2
  • Not all computers have memory card readers take it difficult to download directly from the card.


Disadvantages of flash memory #3
  • Read/write protection isn’t as secure as some other forms of digital storage media.


Disadvantages of flash memory #4
  • Due to their size… The flash memory cards or sticks or more easily left behind, lost, stolen or misplaced.


Disadvantages of flash memory #5
  • Large hard drives still have much more capacity at this point.


Disadvantages of flash memory #6
  • * Flash memory is subject to “Memory Wear.


What Is “Memory Wear” in Flash Memory Devices?

Flash memory – memory wear

Flash
memory is subject to what is called “Memory Wear”.

Flash
memory is essentially a collection of
tiny capacitors that are charged and
discharged continuously as data is
written or retrieved from memory.

The Golden Rule Is…

Always backup your video footage to another digital media storage device or cloud storage and you’ll always be okay!

The memory wear comes from this … 

To activate the capacitors…  A relatively higher voltage than normal is needed to push electrons across the insulating layer of the capacitor to charge it. 

The insulating layer is extremely thin and the process of charging and discharging (reading/writing/erasing) will eventually burn a hole in the material.

This is  “Memory Wear”.

Most
flash memory is guaranteed to withstand about 100,000 P/E cycles before the
memory wear begins to affect the data integrity.

Actually… 100,000
P/E cycles is pretty good…! 
But… you just have to make sure that you’re aware that at some point the flash memory will deteriorate.

 So… Just remember that… Because at that point the memory stick or card will start to malfunction or fail.


Flash memory for camcorders has quickly
become the most popular form of memory storage for digital devices… and for good reason!

It’s easy to use, compact
and lightweight, fast, powerful and affordable.

The continuing advent of smaller and smaller digital devices will ensure that flash
memory will be around for a long time…!

Have fun…!  Dan (Editor)
