Things to consider
This card is a stronger fit for endurance and dependable continuous recording than for users chasing the fastest transfer speeds available in specialist creator or pro media cards.
Device compatibility score
8/10 - strong fit for many compatible microSDXC devices, especially recording-focused gear, but device support should still be checked before purchase.
4k video suitability
7/10 - suitable for many everyday 4K-capable use cases in compatible devices, but specialist high-bitrate video work may benefit from faster card classes.
Professional vs everyday use fit
Best matched to endurance-focused everyday and semi-professional recording rather than peak-performance media workflows.
Durability rating
9/10 - endurance-focused design makes it a strong choice for repeated, long-duration recording environments.
Key benefits
- 256gb capacity: Gives you substantial room for video footage, photos and app data before needing to offload files.
- Pro endurance design: Better suited to long-duration recording tasks than general-purpose memory cards.
- Microsdxc format: Works with a wide range of compatible cameras, recorders and portable devices that support microSDXC media.
- Uhs-i interface: Supports mainstream compatible devices that use the common UHS-I card standard.
- Class 10 rating: Suitable for recording tasks that need a Class 10 performance baseline.
- Compact storage upgrade: Adds significant storage without taking up extra space in compact devices.
- Samsung brand backing: Appeals to buyers who prefer a well-known storage brand for everyday reliability.
- Long-run recording focus: A practical choice for setups that repeatedly overwrite footage over time.
Q: Will this card work in any device with a microSD slot?
A: No. Samsung PRO Endurance works in devices that support microSDXC cards, not every device with a microSD-shaped slot. The included adapter helps it fit standard SD slots, but it does not bypass a device's card-format or capacity limits.
Q: Why is this card suited to dash cams and security cameras?
A: Samsung PRO Endurance is built for long-duration recording, so it suits devices that repeatedly overwrite footage. That makes it a stronger fit for dash cams and security cameras than cards aimed mainly at occasional file storage.
Q: Can this Samsung card handle 4K recording in compatible cameras?
A: Yes. Samsung PRO Endurance carries U3, V30 and Class 10 ratings, which suit many Full HD and 4K recording jobs in compatible devices. It is not positioned as a high-bitrate specialist media card for peak-performance video workflows.
Q: How fast is this card for copying or saving files?
A: Samsung PRO Endurance offers read speeds up to 100MB/s and write speeds up to 40MB/s when used in compatible hardware. That is suitable for mainstream recording and file moves, but it is not aimed at top-end creator transfer speeds.
Q: Does the included adapter let it fit full-size SD slots?
A: Yes. The included adapter lets this microSD card be used in devices with a standard SD card slot. It does not change the card format underneath, so the device still needs to support microSDXC capacity and UHS-I operation.
