Intenso Rainbow Line 3502450 — 4 GB USB 2.0 Flash Drive, Blue
4 GB capacityUSB 2.0 Type-ARead up to 28 MB/sColour-coded: blue
The Intenso Rainbow Line 3502450 is a 4 GB USB 2.0 flash drive in transparent blue plastic, 65 x 19 x 9 mm, sold under EAN 4034303008513. Intenso gives every Rainbow Line capacity its own colour, so the blue body tells you at a glance that this is the 4 GB one. Intenso publishes up to 28 MB/s read and up to 6.5 MB/s write for the whole line, which is quick enough that photos and documents open instantly, while writing a full 4 GB takes roughly 10 minutes. It is a straightforward, cheap stick for handing files around, printing from USB and keeping a driver or recovery kit — not a drive for regular video transfers. If you are not sure 4 GB is enough, tell us what you want to carry and we will size it for you.
Compatibility — check before buying:
The plug is USB Type-A. It works in any USB-A port and runs in USB 3.x ports at USB 2.0 speed; it does NOT fit a phone or a USB-C-only laptop without a USB-C to USB-A adapter. Intenso publishes no file system, no cap or key-ring detail and no box contents for the Rainbow Line, so expect the drive alone. Watch the article numbers: there is no three-pack of the 4 GB; 3502463 is three 8 GB drives, not a 4 GB variant. Colour and capacity go together in this line: blue is 4 GB, green is 8 GB, black is 16 GB, transparent is 32 GB.

✓ Driver, BIOS and recovery sticks

Key Features
One colour per capacity
Intenso colours the Rainbow Line by size: blue means 4 GB. In a drawer of sticks you know which is which without plugging them in.
Honest USB 2.0 speed
Intenso publishes up to 28 MB/s read and 6.5 MB/s write for the line. Documents and photos copy in moments; a full 4 GB takes about 10 minutes to write, so it is not built for large video files.
Plug and play
No driver and no software. Intenso lists Windows 10 or newer and macOS 10.x or newer, and the stick also works in TVs, car radios and printers that read USB drives.

Frequently Asked Questions
Is the Intenso Rainbow Line 4 GB fast enough for video?
Not for regular use. At 6.5 MB/s write, a 2 GB film takes about 5 minutes to copy on. For frequent video work choose a USB 3.2 Gen 1 stick.
Does it work with a phone or a USB-C laptop?
Only through a USB-C to USB-A adapter. If your devices are USB-C only, ask us for a USB-C or dual-plug drive instead.
Why is the 4 GB blue — can I choose another colour?
No: in the Rainbow Line the colour is fixed by capacity. If you want the same look in another size, you get another colour with it.
What is in the box?
Intenso publishes no box contents for this line, so plan on the drive alone: no cable, no lanyard, no software.
Singular Expert Insight
Within Intenso’s USB 2.0 sticks, the Rainbow Line is the full-size, colour-coded one at 28 MB/s read; the Micro Line is the tiny stay-in-port design at 16.5 MB/s. The 3502450 is the 4 GB step, and its write speed is the same as every other Rainbow size, so buy the capacity you need rather than expecting a bigger one to be faster. Tell us how you will use it and we will confirm the size before you order.
Buyer’s Guide
Buy it if
You want a cheap, recognisable 4 GB stick for documents, photos, printer jobs or a driver kit, and you like knowing the size by its colour.
Skip it if
You copy video or multi-gigabyte files regularly — 6.5 MB/s write means about 10 minutes to fill it. Or your laptop or phone has only USB-C.
Also consider
The green 8 GB 3502460 or black 16 GB 3502470 for more room at the same speed, or the Intenso Micro Line 8 GB if you want a stick that stays in the port.
