Portable memory, what are the safest options
Today technology allows us to do so many more things that in the past.Today we can type of an important document, click save on the computer, and then never have to worry about being able to find that document again.Or you can save pictures.Or movies.Or really any other type of electronic document.And gone are the days of saving on floppy disks or CDs.Today we have something much smaller and portable.But not all portable memory drives were created equally.Some have a much better chance of reliably saving your documents.So here is a brief description of your safest options for portable memory.
Secure Digital and MultiMedia Card
Our first portable memories are the Secure Digital and MultiMedia Card (MMC) standard. MMC has a 24mm x 32mm x 1.5mm storage card of very differing capabilities. MMC cards have largely been outdated by SD equivalents.MMC cards are supported by a wide variety of digital camera makers, as well as manufacturers of portable media players and PDAs, including Kodak, Canon and Samsung. SD cards are capable of storing no more than 2GB.Since 2GB was not sufficient for many people's storing needs, the SDHC (Secure Digital High Capacity) was created.SDHC is the newest evolution of the SD card. SD and SDHC are identical in physical size and shape, and SDHC compatible products will be able to accept both SD and SDHC cards..
CompactFlash is one of the oldest memory card formats still in current use.Its survival in the ever competitive technological world, can be directly linked to the fact that it has been embraced by the professionals, especially for use in professional level digital cameras. CompactFlash cards are easily to spot since they are physically larger than the other formats. There are two standards in the CompactFlash world, called the CompactFlash Type I and CompactFlash Type II. Both use casings that are 43mm wide and 36mm deep, but CompactFlash Type II cards are considerably thicker than their Type I counterparts- 5mm to 3.3mm, respectively. This size difference may also mean that Type I slots can't accommodate Type II cards, although Type II slots can take Type I cards.
Microdrives are about the size of CompactFlash Type II miniature portable hard drives. Hitachi now handles the development of these drives after the company purchased IBM's hard disk division.Unlike flash-memory based devices, Microdrives use actual mini hard drives with read heads and moving parts. This makes them more susceptible problems associated with drop shock, although they are remarkably reliable devices in actual use.
Memory Stick is Sony's invention for portable memory storage.The first Memory Stick format was a small stick measuring 50mm x 21.5mm x 2.8 mm with abilities up to 128MB. This rather small storage offering was quickly outpaced by other companies and even with the introduction of a transferable Memory Stick variant (Memory Stick Select), larger capacities were needed to keep pace with Sony's array of Memory Stick compatible devices.Soon after, the Memory Stick Pro was created, which supports storage sizes up to 4GB with write speeds at a minimum of 15Mbs.
USB Keys, which are also known as Thumb drives, Pen Drives or Flash Drives, are basically NAND Flash Memory chips attached to some simple circuitry for read/write operations and a USB plug.USB Keys are anywhere from 8MB up to 8GB with prices increasing as you require more storage space.They are mostly designed as storage media for PC products, though there are devices that will let you use USB Keys with other devices such as home game consoles.
Basically, the safest option for you depends on what kind of storage you're looking for, and what kind of capabilities you want.It's up to you.
