Flash drives are also cost-effective. You can securely store a few dozen gigabytes of data for less than $30, and these devices range in storage capacity, price and overall size - equal to the amount you're willing to invest. Some even have special features like lanyards, locks, belt clips and key fobs to make them easier to carry and keep track of.
USB flash drives are portable and easy-to-use data storage devices. They're compatible with desktop computers and laptop computers as well as a broad range of game consoles and media devices. Use them to transfer data between systems, share files with friends and colleagues or create backups of critical information. Staples offers a complete selection of high-capacity thumb drives, including popular brands such as Lexar, PNY, Samsung, SanDisk and Verbatim.
Original flash memory designs had very limited estimated lifetimes. The failure mechanism for flash memory cells is analogous to a metal fatigue mode; the device fails by refusing to write new data to specific cells that have been subject to many read-write cycles over the device's lifetime. Premature failure of a "live USB" could be circumvented by using a flash drive with a write-lock switch as a WORM device, identical to a live CD. Originally, this potential failure mode limited the use of "live USB" system to special-purpose applications or temporary tasks, such as:
A flash drive consists of a small printed circuit board carrying the circuit elements and a USB connector, insulated electrically and protected inside a plastic, metal, or rubberized case, which can be carried in a pocket or on a key chain, for example. The USB connector may be protected by a removable cap or by retracting into the body of the drive, although it is not likely to be damaged if unprotected. Most flash drives use a standard type-A USB connection allowing connection with a port on a personal computer, but drives for other interfaces also exist. USB flash drives draw power from the computer via the USB connection. Some devices combine the functionality of a portable media player with USB flash storage; they require a battery only when used to play music on the go.
Also, HP has introduced a USB floppy drive key, which is an ordinary USB flash drive with additional possilibility for performing floppy drive emulation, allowing its usage for updating system firmware where direct usage of USB flash drives is not supported. Desired mode of operation (either regular USB mass storage device or of floppy drive emulation) is made selectable by a sliding switch on the device's housing.[51][52]
The development of high-speed serial data interfaces such as USB made semiconductor memory systems with serially accessed storage viable, and the simultaneous development of small, high-speed, low-power microprocessor systems allowed this to be incorporated into extremely compact systems. Serial access requires far fewer electrical connections for the memory chips than does parallel access, which has simplified the manufacture of multi-gigabyte drives.
The advent of USB 3.0 makes data transfers over ten times faster than USB 2.0. If you have USB 3.0 port on your device, and you transfer files on a regular basis, the added speed on the PNY flash drive can be a big boost for getting things done (Even if you have a USB 2.0 port, you can still use USB 3.0, but you won’t get the same speeds). Pros: Fastest file transfers of any of the options. Cons: Some found the built-in external cover difficult to move. Image Courtesy of Amazon
To ensure this information isn't stolen as well, having a locked flash drive can keep anyone from viewing your files should the drive fall into the wrong hands. Tiny and portable, they easily slip into a pants or coat pocket, in a computer bag or purse, and come in a variety of shapes and sizes. External keypads add an additional level of security to portable memory, meaning a viewer must first input a numerical code to gain access to files. These in turn can be encrypted and password protected, deterring serious threats to personal security.
Specially manufactured flash drives are available that have a tough rubber or metal casing designed to be waterproof and virtually "unbreakable". These flash drives retain their memory after being submerged in water, and even through a machine wash. Leaving such a flash drive out to dry completely before allowing current to run through it has been known to result in a working drive with no future problems. Channel Five's Gadget Show cooked one of these flash drives with propane, froze it with dry ice, submerged it in various acidic liquids, ran over it with a jeep and fired it against a wall with a mortar. A company specializing in recovering lost data from computer drives managed to recover all the data on the drive.[64] All data on the other removable storage devices tested, using optical or magnetic technologies, were destroyed.
This drive’s small size won over our testers: “Its small profile allows it to stay plugged into a computer even when transporting it in a bag or case, which is not something most flash drives can claim,” one person said. Lifewire reviewers agree that the drive’s tiny footprint makes it much more likely to get lost, but they say its fast read speeds and convenient portability easily make up for that.
Unlike solid-state memory, hard drives are susceptible to damage by shock (e.g., a short fall) and vibration, have limitations on use at high altitude, and although they are shielded by their casings, they are vulnerable when exposed to strong magnetic fields. In terms of overall mass, hard drives are usually larger and heavier than flash drives; however, hard disks sometimes weigh less per unit of storage. Like flash drives, hard disks also suffer from file fragmentation, which can reduce access speed.
High-security flash drives aren’t exactly a new concept. For as long as companies have been transferring confidential info via USB drives, there’s been a concern of keeping that info confidential. While you might be swayed by flashy gimmicks like fingerprint sensors and password keypads, these end up being too expensive and not overly powerful (with a few exceptions of course). But that’s why our security pick goes to the Kingston Data Traveler Vault.
Most USB flash drives do not include a write protection mechanism. This feature, which gradually became less common, consists of a switch on the housing of the drive itself, that prevents the host computer from writing or modifying data on the drive. For example, write protection makes a device suitable for repairing virus-contaminated host computers without the risk of infecting a USB flash drive itself. In contrast to SD cards, write protection on USB flash drives (when available) is connected to the drive circuitry, and is handled by the drive itself instead of the host (on SD cards handling of the write-protection notch is optional).
Third generation USB flash drives were announced in late 2008 and became available in 2010.[citation needed] Like USB 2.0 before it, USB 3.0 dramatically improved data transfer rates compared to its predecessor. The USB 3.0 interface specified transfer rates up to 5 Gbit/s (625 MB/s), compared to USB 2.0's 480 Mbit/s (60 MB/s).[citation needed] By 2010 the maximum available storage capacity for the devices had reached upwards of 128 GB.[7] USB 3.0 was slow to appear in laptops. As of 2010, the majority of laptop models still contained the 2.0.[23]
The world is becoming increasingly virtual, which means fewer people print documents unnecessarily and opt to share them electronically instead. Rather than spend time and resources on information packs, why not use custom USB flash drives to provide your audience with the information they need? Our wholesale flash drives can be customized with your logo or brand name for a personal touch they can remember you by.

Universal Disk Format (UDF) version 1.50 and above has facilities to support rewritable discs like sparing tables and virtual allocation tables, spreading usage over the entire surface of a disc and maximising life, but many older operating systems do not support this format. Packet-writing utilities such as DirectCD and InCD are available but produce discs that are not universally readable (although based on the UDF standard). The Mount Rainier standard addresses this shortcoming in CD-RW media by running the older file systems on top of it and performing defect management for those standards, but it requires support from both the CD/DVD burner and the operating system. Many drives made today do not support Mount Rainier, and many older operating systems such as Windows XP and below, and Linux kernels older than 2.6.2, do not support it (later versions do). Essentially CDs/DVDs are a good way to record a great deal of information cheaply and have the advantage of being readable by most standalone players, but they are poor at making ongoing small changes to a large collection of information. Flash drives' ability to do this is their major advantage over optical media.
