Most modern laptops have three USB ports, and they are not always the fastest. Desktops may have more ports, but it's likely all USB 2.0.
Which
is a shame because USB 3.0 has ten times faster transfer speeds than USB 2.0,
offers more power, and helps save energy by reducing power consumption when
peak charging is not required?
Pen
drives or USB memories allow us to store files or move them from one place to
another. Do you want to know the different connection modalities? What speed
does each offer? We will tell you with buying advice.
There
was a time when USB storage units or flash
drives were very similar 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 connection methods such as USB 3.0, USB 3.1,
USB Type C, or even Thunderbolt emerged. As the specification standard increased,
so did laptops' supported transfer speed and charging capabilities.
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
reading and writing speeds, and the security and encryption measures.
In
an era in which cloud storage services such as Google Drive, Dropbox, OneDrive,
or iCloud, among others, prevail, there are times when it is still necessary to
have physical access to your files without relying on an Internet connection.
It
is also the case that current pen
drives or USB flash drives
support large file sizes, which many cloud services resist. And no less
important is the security factor, mainly if we handle business documents to
encrypt them.
There
are also other factors to consider, such as the design, size, type of
connector, and support used. We will talk about all these factors below in the
compilation that we have made of the best USB flash drives that you will find
for sale.
If
it turns out that you have bought one of these memories to make a backup copy
of Windows 10, take a look at this article, where we show you how to make a
backup copy of your files and the system.
What storage capacity do I need?
This
is a simple question, but have you stopped to think, how much storage do I need
the USB memory to have for my daily use?
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 so, so
there are not many reasons to buy a smaller one.
That
will probably be enough for most purposes, but if you're going to use it to
create bootable OS drives, transfer 4K video, or something similar, you might
want to spend a bit more for a 64GB memory card or 128GB, or even a whopping
1TB drive.
USB formats
It's
worth noting that you'll only benefit from the extra 3.0 speed when using
the drive with a compatible port. Check if your computer or devices have 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 compatible with 2.0 ports; you won't benefit more
quickly.
You'll
also see some memory cards that support USB 3.1, which is even faster (10
Mbps). However, you should not necessarily be attracted to advertising.
Reading Speeds
While
3.1 is theoretically twice as fast as 3.0, you're unlikely to benefit from the
extra speed unless you have a newer computer or other devices with 3.1 ports.
But
wait, does your laptop or PC have a USB 3.1? It will most likely still be 3.0.
You might even see USB 3.2 on some USB drives, which supports speeds of up to
20Gbps.
This
is where things can get a bit confusing, thanks to a naming convention change
announced in 2019 by the people who decide these things. The 3.2 standard
encompasses 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 genuine 3.2 connection at 20Gbps speeds will be listed as
USB 3.2 Gen 2x2, which means two 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 standard.
Speaking
of which, it's now possible to buy some USB-C memory cards, which take
advantage of the rise of smaller reversible USB-C ports on phones,
tablets, and laptops.
Even
better, some drives feature USB-A and USB-C connectors, so you can access the
same files from a variety of different devices, or even a Lightning connector
so you can connect to an iPhone or iPad.
Transfer speeds
Transfer
speeds are determined in part by the USB standard the drive uses, but there is
also a lot of variation between different memory cards depending on their
manufacture.
The
drives talk about reading and writing speeds. Read speeds are essential for
playing files from devices, proper if you want to watch a movie you've saved to
a flash drive, and are generally much higher.
Write speeds are more important if you frequently transfer large files or save them directly to the drive. It's not unusual to see these being much lower than reading speeds, which means that if a drive advertises a single speed without specifying what it is, it's almost certainly the read speed.
