(If you are using Windows, open up "My Computer" to see which drive is showing as the drive in use for the pen drive). Depending on how your computer is set up, this means you can probably copy files onto the jump drive in one or two ways.įirst, you can located the file you want to copy to the drive, do a "save as" and save the copy to whatever drive your computer is identifying as the pen drive. Inserting the pen drive into a USB port is like putting a blank CD into your machine. So why cobble together a “solution” from several different programs that aren’t designed to work well together, when you can have it all in one convenient, cohesive custom system?

well, by a tiny app on your smart phone today.Įvery business has different needs, from finances to supplies, right down to the features of the software used in daily operations.įinding the right software to suit your needs can be frustrating, especially when every piece of software you evaluate has dozens of features you don’t need, but is missing crucial features you do need. What took a room-sized computer 50 years ago can easily be done by.

This can make the device mark some blocks as bad, even though they are not completely full trying to read bad blocks and remapping them can reduce the speed with which the device functions.Ī standard CD-ROM holds about 700 MB of data.Īs technology continues to evolve, expand and mature, it offers new and unprecedented challenges, as well as fresh and exciting opportunities. The NAND gate-style method of programming and erasing files that are smaller than a block can also slow things down. The computer chip in the drive can also wear out, causing the device to operate more slowly. Generally, a user must read the cell thousands of times before this occurs, however, and rewriting the surrounding cells periodically may prevent this problem. Reading data in one cell may trigger changes in the cells that surround it. The NAND gate-style device also may cause the loss of data because of the way that the information is accessed.

When only small amounts are erased, the storage capacity is reduced. The NAND gate-style allows a user to program or read the data one byte or word at a time, but erases data in blocks. Typically, the device can go through 100,000 P/E cycles before the integrity of the unit is compromised and files become corrupted.Īnother limitation concerns the way manufacturers build the devices. Each drive has a limited number of program-erase cycles (P/E cycles), which is the act of putting files onto the drive and erasing them.

Pen drives do have a few limitations, including how many times they can be used. There are also programs that can be run directly from the drive, without needing to be installed on the computer first. Any file that can be stored on a computer's hard drive can usually be copied to a flash drive, as long as there is enough memory. Depending on the storage size, flash drives can hold anywhere from 128 MB to 32 GB or more by comparison, a standard CD-ROM holds about 700 MB of data.Įven a pen drive with a relatively low storage capacity tends to provide plenty of space for all different types of files. Because they are solid state - there are no moving parts - flash drives usually last longer and the data stored on them is safer. They can transfer data much more quickly than these older technologies. BenefitsĮquipped with a large amount of memory, the pen drive is often considered to be an improvement on both the older floppy drive disks and the more modern compact disks. The age of the drive and how it's being used - such as for writing and erasing small files - also affects the transfer speed. Manufacturers usually list the speed in megabytes per second (MB/s). Generally, a pen drive's advertised speed is the reading speed because it is faster than the speed at which data can be written to it. The actual transfer speed depends upon several factors, such as the computer's speed at reading and writing to the device. Using blocks rather than allowing random access allows the drive to store more information and be made at a lower cost. This technology works by storing data in blocks rather than randomly as such, it doesn't work in the same way that a computer's main memory systems - read-only memory (ROM) and random-access memory (RAM) - do. Technicians classify pen drives as NOT AND, also called NAND, gate-style data storage devices.
