A USB drive, also known as a USB flash drive, USB stick, or pen drive, is a small, lightweight, removable data storage device that uses flash memory and connects via a USB interface (McCandless, n.d.). Flash memory is a type of nonvolatile memory that can be erased electronically and rewritten. USB drives are frequently used to store, back up, and transfer files between computers or other devices.
The main uses of USB drives include transferring files between different devices, backing up and storing files from a computer, sharing files with others, and running portable software applications. Their small size, lack of moving parts, and plug-and-play functionality have made USB drives a convenient portable storage medium for general consumer use.
This article will compare USB drives to the older storage technology of flash drives. It will look at the differences and similarities between the two in terms of storage capacity, speed, durability, compatibility, security, price, and typical use cases.
History
The USB flash drive traces its origins back to the late 1990s. In 1998, a Singaporean company called Trek 2000 International, founded by Henn Tan, is credited with developing the first USB flash drive and bringing it to market (https://en.wikipedia.org/wiki/USB_flash_drive). The original USB flash drive was called the “ThumbDrive” and had a storage capacity of 8MB. It became commercially available in 2000, after Trek 2000 collaborated with IBM to incorporate USB flash drive compatibility into IBM’s USB-equipped notebooks (https://spectrum.ieee.org/thumb-drive).
The advent of the USB flash drive was enabled by the development of the USB interface standard in the mid-1990s. USB allowed for plug-and-play connections between peripherals and computers, doing away with previous ports such as serial and parallel ports. This plug-and-play connectivity made the USB flash drive a highly convenient portable storage device compared to previous options like floppy disks (https://www.usbmemorydirect.com/blog/history-of-usb-flash-drives/).
Storage Capacity
USB flash drives and flash drives have a wide range of available storage capacities. USB flash drives typically range from 64MB to 128GB, while flash drives often go up to 4TB (https://enfain.com/faq/flash-drives-capacity-chart/). There is considerable overlap in capacities between the two storage devices, but flash drives tend to have higher maximum capacities.
For most everyday uses like transferring documents or photos, lower capacity USB flash drives under 32GB are sufficient. Higher capacities in the 64-256GB range are useful for storing large media files or system backups. Professionals working with very large files may need drives over 1TB (https://recoverit.wondershare.com/flashdrive-recovery/usb-flash-drive-size.html).
In summary, both USB flash drives and flash drives come in a wide range of storage sizes to suit different needs. Flash drives can offer larger maximum capacities over 1TB, while most USB flash drives top out below 256GB.
Speed
When comparing read and write speeds between USB drives and flash drives, flash drives tend to have faster performance. According to https://www.usbmemorydirect.com/blog/flash-drive-read-write-speed/, USB 2.0 flash drives have average read speeds between 10-25 Mbps and write speeds between 3-10 Mbps. In contrast, USB 3.0 and newer flash drives can reach speeds up to 625 MB/s for reads and writes.
For traditional spinning hard drives connected via USB, read and write speeds are much slower. As noted on Reddit, USB 3.0 connected hard drives will see speeds around 140-180 MB/s for sequential reads and writes. This is still well below the potential maximum speeds of USB 3.0 flash drives.https://www.reddit.com/r/hardware/comments/cysbjc/how_fast_are_usb_30_flash_drives_compared_to/
The superior speeds of flash drives over USB hard drives come from the solid-state memory. Flash memory can be read and written to very quickly compared to mechanical hard drives. So for tasks that need fast data transfer like moving large files, flash drives have a clear speed advantage.
Durability
USB flash drives tend to be more durable and have a longer lifespan than external hard drives. While external hard drives have moving mechanical parts that can fail, flash drives are solid state with no moving parts. According to one source, flash drives can withstand between 10,000 to 100,000 write/erase cycles depending on the memory technology used (https://www.flashbay.com/blog/usb-life-expectancy).
However, flash drives are not infallible. Their performance and storage capacity can degrade over time with excessive use. And they are still susceptible to physical damage from drops, liquids, magnets, etc. Proper handling and storage can extend the lifespan of a flash drive. Overall, flash drives tend to be more durable for portable storage, while external hard drives are better suited for intensive everyday use if protected properly (https://www.salvagedata.com/external-hard-drive-vs-usb-flash-drive/).
Security
When it comes to security, USB flash drives have some notable vulnerabilities compared to USB tokens. Unlike USB flash drives, USB tokens utilize hardware-based encryption to protect data (Yubikey, 2022). This makes USB tokens far more secure as the encryption keys are stored on a dedicated security chip rather than relying solely on software-based encryption.
USB flash drives do not have built-in encryption. While software encryption tools like BitLocker can be used, this still leaves the drive vulnerable when plugged into an unsecured device (Wikipedia, 2023). USB tokens provide protection even when used with an infected computer.
In summary, USB tokens are designed from the ground up to be secure portable devices ideal for sensitive data. USB flash drives lack hardware-based security and are far more vulnerable to data theft and malware without additional software protection.
Compatibility
USB flash drives generally have very broad compatibility with different operating systems and devices. Most flash drives will work with Windows, macOS, Linux, Chrome OS, Android smartphones/tablets, game consoles, cars, smart TVs and more without any issues.
This is because flash drives use the ubiquitous USB connection standard which has wide industry adoption. As long as a device has a USB port, it will likely be compatible with a standard USB flash drive. This includes USB 2.0, USB 3.0, USB 3.1 and USB 3.2 ports. The flash drive will connect at the maximum speed the USB port supports.
According to the USB Implementers Forum, over 10 billion USB devices were sold in 2021, highlighting the universal adoption of USB technology (https://www.usb.org/sites/default/files/2021%20USB%20By%20the%20Numbers%20FINAL.pdf). This broad compatibility across devices and platforms makes USB flash drives extremely convenient for transferring data.
Some high speed USB 3.2 flash drives may have connectivity issues with legacy hardware that only supports USB 2.0. But most standard USB flash drives will work seamlessly across nearly any modern computing device with a USB port.
Price
USB flash drives and thumb drives tend to be very affordable, with prices ranging from around $5 to $100 depending on capacity and speed. Lower capacity drives like 8GB can easily be found for under $10 from mainstream brands. Drives between 16GB to 64GB typically cost $10 to $30. Higher capacity drives like 128GB and above range from $20 up to $100 for 1TB models.
There are significant price differences between basic/budget drives and higher-end/premium models. Budget drives use lower-quality components which impacts durability and speed, but allows the price to be kept very low. Premium drives from brands like SanDisk use higher-quality NAND flash memory, advanced controllers, and robust housing materials. These result in better performance and reliability, but at 2-4x the cost over basic models of the same capacity.
In general, the price per GB decreases significantly as capacity increases. So a 128GB drive often costs just 2-3 times more than a 16GB drive. This makes high capacity drives very cost effective for storing large amounts of data if speed is not the top priority.
Compared to optical discs like DVDs and Blu-Rays, USB drives have become much more affordable over the past decade, especially for capacities up to 32GB. Blank Blu-Ray discs remain more cost effective for very large archival data, but USB drives are more convenient to use.
Overall USB flash drives provide lots of affordable options for transporting and storing data, with speed, durability and capacity improving as you pay more. Even basic models work reliably for everyday usage.
