Memory Sticks & Portable USB Drives

A USB flash drive allows you to quickly and easily transfer files between two devices. It is currently one of the most widely used storage media for data transfer. Most often, it varies in capacity - today you can buy a pendrive from 4 GB to 2 TB. What capacity and speed to choose? We'll give you some advice.

USB Flash Drive: Capacity Table

Capacity	Video (DVD)	Music (mp3)	Photos (JPG)
4 GB	0 – 1 film	800 songs	1,000 photos
8 GB	1 – 2 films	1,600 songs	2,000 photos
16 GB	3 films	3,200 songs	4,000 photos
32 GB	6 films	6,400 songs	8,000 photos
64 GB	13 films	12,800 songs	16,000 photos
128 GB	26 films	25,600 songs	32,000 photos
256 GB	53 films	51,200 songs	64,000 photos
1 TB	212 films	200,000 songs	256,000 photos

Flash Drive: Indicative Data Transfer Time Table

Another important parameter when choosing a flash drive is its write and read speed. It is usually specified in MB/s. The write speed indicates the speed at which the USB drive can write, i.e. store data. The read rate tells how much data the pendrive is able to access in one second.

File type	File size	Write time to flash drive		Copy time from flash drive
File type	File size	USB 2.0	USB 3.2 (previously USB 3.1)	USB 2.0	USB 3.2 (previously USB 3.1)
Full HD film	15GB	31min	3.5min	7.5min	1min
100 photos	1GB	2min	15s	65s	9s
50 songs	250MB	31s	4s	20s	3s

USB Flash Drive: Interface and Transfer Speed

A flash drive communicates with a computer or device using a USB (Universal Serial Bus) port. It is the interface of a pendrive that determines its maximum theoretical transfer rate (it is given in Mb, 1 MB = 8 Mb). Flash drives are nowadays most often equipped with USB 3.2 Gen 1 connectors (formerly known as USB 3.1 or USB 3.0), which you can recognise very easily - they are distinguished from previous versions by their blue connector.

USB 2.0 - 480 Mb/s
USB 3.2 Gen 1 (3.1 Gen 1) - 5 Gb/s
USB 3.2 Gen 2 (3.1 Gen 2) - 10 Gb/s

OTG Flash Drives

USB flash drives labelled in this way can be connected to mobile phones or tablets that support OTG. OTG Flash drives allow you to transfer data from your smartphone directly to the pendrive, and vice versa. This is a practical accessory to expand the storage space of your connected device.

USB-C Flash Drives

The size of the connector roughly corresponds to the well-known micro USB, but it offers a number of advantages. The most general advantage of a USB-C Flash drive is its symmetrical shape, which allows the connector to always get plugged in on the first try. At the same time, USB-C enables support for all USB standards, including USB 3.2 Gen 2. USB-C can support network connectivity via Ethernet and video transmission using HDMI 2.0.

Lightning Flash Drives

These are USB drives with a Lightning connector, which is primarily designed for Apple devices. This allows you to easily transfer data between your computer and your Apple device.

WiFi Flash Drives / Wireless Flash Drives

Flash drives marked as such allow wireless connectivity via Wi-Fi. The advantage of WiFi pendrives is automatic data downloading and backup. You can use them e.g. for the data from your phone.

Memory Sticks & Portable USB Drives - additional info

USB flash memory, simply referred to as Flash Drive, is a data medium considered as the successor to floppy disks. Flash memory is not erased when the power is removed from the host device, and often take the form of keychain attachments. As is evident from the title, they connect to computers via USB sockets. They were firstly produced on a commercial scale in 2000 by IBM and Trek Technology.

The first models had a capacity of 8 MB which was five times greater than the floppy disks which were still used at that time. Modern flash drives now have capacities ranging from 512 MB to tens or hundreds of GB (upper limit is constantly increasing) and support USB 2.0. They are made of different materials, including plastic, metal or rubber, and in addition to backing up data, they are compatible with other technologies such as ReadyBoost and U3.
