You need at least a 32GB USB stick, but 128GB or larger is recommended for HD/4K recording, with USB 3.0+ for better speeds; 128GB holds about 16-20 hours of 1080p video, while 256GB holds much more, and you'll need to check your TV's manual for compatible file systems (like NTFS or FAT32) and minimum size requirements.
We recommend using a USB stick with a storage capacity between 32GB- 1TB so you have plenty of space to store your recordings.
If you have recently bought a new TV there is good chance that it will support USB Recording, in particular when you have bought a mid range or high end TV. USB Recording enables you to record programmes to an external storage device directly connected to your TV via USB.
There's no practical difference between a flash drive and a USB stick; they are different names for the same thing, referring to a portable storage device using flash memory that connects via a USB port, also called a thumb drive or pen drive. "Flash drive" is the technical term from its technology, while "USB stick" describes its shape and interface, used interchangeably for these compact, key-chain-friendly devices for file transfer and storage.
720p (High Definition): A step up in quality, 128GB can accommodate around 40 hours of 720p HD video. 1080p (Full HD): With its higher bitrate, you can store approximately 16-20 hours of 1080p Full HD video on 128GB. 4K (Ultra HD): At this resolution, a 128GB storage device can hold around 3 hours of footage.
How long do you plan to keep the phone? 2–3 years → 128GB. 4–5 years → 256GB.
For example, on 256GB, you can fit over 16 hours of 4K footage at a low bitrate of 35 Mbps or about one and a half hours of 4K footage recorded on a high-end camera at 400 Mbps. So it really depends on the capabilities of your camera and which settings you're shooting with.
Disadvantages
ICYMI: USB flash drives are being replaced by Portable SSDs, high-capacity SD cards, and Cloud Storage. Compare speeds, costs, and the best picks for 2026.
In short, the flash drive size you choose should depend entirely on what you plan to store on it. For just a few photos and smaller files, you can get away with a 64 or 128 MB card. For sharing large quantities of high-definition photos, we always recommend the higher end of the MB offerings (256 or 512 MB) or 1 GB+.
Lowest Price Guaranteed! By far the easiest way to watch and record television, a PVR allows you to record one TV channel whilst watching another, pause live TV and record entire series with the touch of a button on their large built-in hard disks.
If you get an out-of-memory message
If your TV memory is full and you try to download a new application, the TV will inform you about insufficient storage and ask you to delete apps or content you no longer use. If your TV is stuck, turn it off and back on to clear the system memory.
Most modern TVs support common file systems like FAT32 and exFAT. However, some older models may only support FAT32. It's essential to choose a USB stick that is compatible with your TV's file system requirements to ensure seamless recording and playback.
If the power is insufficient, your Smart TV may not properly recognize the USB device. We recommend using only USB storage devices with a capacity of 32 GB or less. We recommend using only USB hard drives with a capacity of 2 TB or less.
If you need to check the storage space on a USB, you can easily do so by plugging it into a Windows or Mac computer. Most flash drives have the capacity printed on the flash drive itself, but you must have a computer to check how much space is left inside.
You can record to a USB HDD of 80 GB or more, or a USB Flash Drive of 4 GB or more. When the USB Flash Drive is used for its first recording, the TV goes through a performance test. You can record only when the test is complete. Bluetooth and the USB port may not work properly when recording with a USB device.
No, thumb drives aren't completely obsolete, but their use has declined as cloud storage and faster portable SSDs offer better solutions for many tasks, though they remain valuable for offline file transfers, installing operating systems (bootable drives), and moving data to network-isolated (air-gapped) systems. Their low cost, simplicity, and offline nature keep them relevant for specific uses, but they're often replaced by faster, higher-capacity options for general purposes.

As well as the cybersecurity risks posed by plugging in USB drives, they also lack built-in security features. While USB drives can be encrypted to protect the data held within, most people do not know how to do this, or simply neglect to.
A USB drive' longevity also depends on the type of connector used, such as a USB-A vs. USB-C, and the overall build quality of its circuits and protective shell. Most devices can withstand between 10,000 and 100,000 cycles. Many manufacturers provide an estimated lifespan for their devices of 10 years.
For safe and permanent file deletion from usb drive, the deleted data needs to be overwritten with new, meaningless data to prevent any chance of recovery. This process ensures that even with sophisticated forensic tools, it becomes extremely difficult or impossible to reconstruct the original file.
Custom USB sticks, also known as flash drives or thumb drives, have become an integral part of our digital lives. These small and portable devices offer a convenient way to store, transfer, and backup data.
A 2-hour 4K movie file size varies wildly from 10-15 GB for heavily compressed streams up to 40-90+ GB for high-bitrate Blu-ray rips, depending heavily on compression (H.264 vs. H.265/HEVC), HDR, audio quality (Dolby Atmos), and bitrate; streaming is typically 7-15 GB/hour, while discs hold much more.
Signs of a Failing SD Card
Read/Write Errors: If you start experiencing frequent read or write errors, it could be a sign that your SD card is failing. This might manifest as files that won't open, error messages when trying to save data, or the inability to format the card.
