Features of Flash Drives

When you are looking to buy a flash drive, choose one with a large capacity. One because you don’t want to run out of space when you need it, and two the price difference is not that significant up to 256GBs. With that in mind, here are some of the features you should look out for when buying the best flash drive for a small business.

  • Portability: It is given flash drives are small and portable. However, make sure they are not so small you can lose them. Look for loops and clips so you can attach them to your keys, belt loops, bags, etc.
  • Durability: The very design of a flash drive makes it durable. The key is to buy drives with a hard case made of metals, alloys, or very hard plastics.
  • Capacity: You can get drives from hundreds of megabytes to terabytes. But storage capacity alone is not enough, transfer rate being another important factor.
  • Transfer rate: When you connect devices with different USB specifications, the transfer rate is going to be limited by the slowest of the connected devices. If you have 500GB of data you want to transfer, you don’t want a 2.0 drive with megabytes per second rate. The latest specification in USB drives can transfer up to 20Gbs, which will zip through those 500Gbs in a breeze.
  • Compatibility: Make sure your flash drive and computer are compatible when it comes to formats. If you have a 2.0 USB computer and a 3.1 USB flash drive, the transfer rate is going to throttle down to 2.0. And vice versa if the flash is 2.0 and the computer is 3.1.

Failure Rate of USB Flash Drives

Flash drives will fail as you write and delete more files. You can write over the standard USB flash drive between 3,000 to 100,000 before it fails. However, it can go as high as millions of write and erase operations. But technology being what it is, anything can happen at any given moment.

Other factors responsible for your flash drive failing include eject/mount and electrical component failure. This means you shouldn’t remove the drive while it is still accessing files or communicating with your computer.

As the drive starts to reach its limit, segments of the memory may start failing resulting in data corruption and even loss. That is why it is always wise to store your data in more than one place. And of course, the longevity of your flash drive will greatly depend on the quality of the manufacturer. Look for manufacturers using grade A memory and have ISO-9001:2008 certified factories.

Storage Capacity

First, the capacity of a drive is more likely to be lower than the stated amount once the drive is formatted and mounted on an operating system. But there is a larger discrepancy, such as seeing 7.48GB on an 8GB flash drive on a Windows PC.

This is because storage manufacturers use the 1KB = 1000 bytes denomination and RAM manufacturers use 1KB = 1024KB denomination. So, when you insert the 8GB flash drive, your PC is reading it in denominations of 1024. And while it reads less than 8GB, you still have 8GB of available storage, minus the formatting.

Flash Drive Security

If you are using your flash drive to store extremely sensitive information, you must look into more robust security measures. The good news is you can now get flash drives with physical pins to access the drive. Furthermore, there are additional encryption tools you can use to access the drive as well as the files within the drive.

USB Formats

Even though USB 2.0 (60MBs transfer rate) is still around, USB 3.0 is now the standard manufacturers are using. Technically, 3.0 is supposed to have top speeds of 5Gbps, but many factors come to play in achieving those numbers.

Now there are 3.1, 3.2, USB 3.2 Gen1, and Gen 2×2 with max speeds of 20Gbps. There is also a USB 4 on the way with 40Gbps. Again, it is worth mentioning, your computer must be compatible in order to achieve these high transfer rates. There are also flash drives with USB-A and USB-C connectors so you can hook them up on phones, tablets, and laptops with these ports.
