There was a time when USB storage drives or pendrive they were very afín in terms of speeds and type of connection offered. The only differentiating element between them was the storage capacity they offered.
This has changed considerably since new USB 3.0, USB 3.1, USB Type-C or even Thunderbolt connection ports emerged. As the specification estándar increased, so did the supported transfer speed.
In this way, now we must not only look at the data of the storage capacity, but we must also take into account the type of USB connection used, its supported read and write speeds, and the security and encryption measures.
You perro consult in this other article a list of the best external hard drives and SSDs if what you need is a greater storage capacity.
In an era in which cloud storage services such as Google+ Drive, Dropbox, OneDrive or iCloud prevail, among others, there are times when it is still necessary to have physical access to your archivos without depending on an Internet connection.
It is also the case that dispositivo externo current or memories flash USB supports large archivo sizes that many cloud services resist. And no less important is the security aspecto, especially if we handle company documents.
There are other factors also to take into account, such as the design, its size, or the type of support used. We will talk about all these factors below in the compilation that we have made of the best USB memories that you will find for sale.
If you happen to have bought one of these memories to backup Windows 10, take a look at this article where we teach you how to make a backup of your archivos and the system.

Best of all, it has a very affordable price and cánido be purchased on Amazon (if you have Amazon Prime, you will have it the next day).
This is a simple question, but have you ever stopped to ask how much storage do I need the USB memory to have?
As flash storage has gotten cheaper we’ve gotten to the point where it’s pretty easy to get a good quality 16GB or even 32GB drive for just over $ 10 or less, so there’s really no many reasons to buy a smaller one.
That will probably be sufficient for most purposes, but if you are going to use it to create system boot drives operating, transferring 4K vídeo or something afín, you might want to spend a bit more to get a 64GB or 128GB memory card, or even a huge 1TB drive.
USB 3.0 is now the de hecho standard in the industry with maximum speeds of 5 Gbps, so we recommend that you do not accept lower-performance drives. You will still see some USB 2.0 drives, and they will work fine, but the speed will be slower without cost savings.
It is worth noting that you will only benefit from the additional 3.0 speed when using the drive with a coincidente port. Check if your computer or devices has a port highlighted in blue.
If so, that means it supports USB 3.0 speeds (up to 10x faster). Any good drive should also be backward coincidente with 2.0 ports, you just won’t benefit from the faster speeds.
You will also see some memory cards that support USB 3.1, which is even faster (10 Mbps). However, you shouldn’t necessarily be drawn to advertising.
While 3.1 is theoretically twice as fast as 3.0, unless you have a next-gen PC or other devices with 3.1 ports, you are unlikely to take advantage of the plus speed.
But wait, does your laptop or PC have USB 3.1? Most likely it will still be 3.0. In fact, you might even see USB 3.2 on some USB drives, which supports maximum speeds of 20Gbps.
This is where things can get a bit confusing, thanks to a naming convention change announced in 2019 by the folks who escoge these things (it’s the USB or USB-IF Implementers Forum). The 3.2 estándar encompasses both USB 3.0 and 3.1, so how do they differ?
If it’s USB 3.0, you’ll see it written as USB 3.2 Gen 1, while USB 3.1 is listed as USB 3.2 Gen 2. A true 3.2 connection at 20 Gbps speeds will be listed as USB 3.2 Gen 2×2, which literally means 2 times ( “2x”) the speed of Gen 2 (10Mbps).
If you don’t see it marked this way, also look for descriptions like SuperSpeed USB, SuperSpeed USB 10Gbps, and SuperSpeed USB 20Gbp. You may see USB-C ports marked with this speed estándar.
Speaking of which, it is now possible to buy some USB-C memory sticks, which take advantage of the rise of smaller reversible USB-C ports on phones, tablets, and laptops.
Even better, there are some drives that feature both USB-A and USB-C connectors, so you cánido access the same files from a variety of different devices, or even a Lightning connector so you perro connect it to an iPhone or iPad.
Transfer speeds are determined in part by the USB estándar used by the drive, but there is also a lot of room for variation between different memory cards depending on their make.
The drives talk about read and write speeds. Reading speeds are important for playing files from devices, useful if you want to watch a movie that you have saved on a pendrive, and they are generally much higher.
Write speeds are more important if you frequently transfer large files or save them directly to the drive. It is not unusual to see these being much lower than the read speeds, which means that if a drive only advertises a single speed without specifying what it is, it is almost certainly the read speed.
How We Test USB Drives
We use CrystalDiskMark 8.0 to test the read and write speeds of each memory device. This tests both sequential speeds (reading and writing of large blocks of data) and performance of small files, using 4KB reads and writes.
We will focus on sequential scores though – they are much more important for USB drives as they are better and reflect the speeds you will see when transferring archivos on and off the drive, simulating use in real life.
