Samsung T7 microSDXC 256 GB — 170 MB/s read, Class 10 / U3 / V30 / A2

The MB-MB256T/WW is Samsung’s T7 microSDXC card in 256 GB. Samsung rates it at 170 MB/s sequential read, with the Class 10 / U3 / V30 / A2 marks that matter for video recording and for running apps directly from the card. T7 is part of the new range Samsung launched in 2026 to replace EVO Plus, PRO Plus and PRO Ultimate. It slots in as the everyday card for phones, tablets and gaming handhelds. There is one change buyers should know about, and we have put it in the specifications rather than the small print: the T-series carries a 3-year manufacturer warranty where the cards it replaces carried 10. It measures 15 × 11 × 1 mm and weighs about 0.25 g. Typically in stock with fast delivery across Cyprus.
Compatibility — check before buying:
The rated read speed needs the right reader. Samsung reaches 170 MB/s over UHS-I DDR200, a Samsung extension to the UHS-I bus rather than a standard mode — its own footnote says the figure is achieved “using Samsung readers”. In an ordinary phone, camera, laptop or card reader slot the bus tops out at the standard UHS-I SDR104 rate of about 104 MB/s, and that is what you will see. The card is fully compatible either way; only the headline number changes.
Best For
✓ Everyday phone, tablet and handheld storage at a useful size
✓ 4K video on a phone or an action camera
✓ Nintendo Switch and other handheld game libraries
✓ Anyone buying into Samsung’s current line rather than run-out stock
Key Features
Samsung’s new mainstream microSD
T7 replaces the EVO Plus and PRO Plus generation in Samsung’s 2026 range, sitting below the faster T9. It runs the full set of marks — Class 10, U3, V30 and A2 — at every capacity from 128 GB to 1 TB, which the outgoing EVO Plus did not.
U3, V30 and A2 at every capacity
A real improvement over the card it replaces: EVO Plus dropped to U1, V10 and A1 at 64 GB. In the T7 line the marks do not change with size, so you cannot buy the wrong capacity by accident.
170 MB/s read — with the right reader
Samsung reaches 170 MB/s over its DDR200 extension to the UHS-I bus. In a phone, camera or standard laptop slot expect about 104 MB/s, which is the standard bus ceiling. See the compatibility note above.
Three years, not ten
We would rather you heard this from us. Samsung warrants T7 for 3 years; the EVO Plus, PRO Plus and PRO Ultimate cards it replaces are warranted for 10. If warranty length is what you are optimising for, the older names are currently the stronger buy.
Six-proof protection — on Samsung’s own tests
Water to 1 m for 72 hours in 3% saltwater, −25 to 85 °C, airport X-ray to 100 mGy, 15,000 gauss, 5 m drops and 10,000 insertions. Samsung’s internal claims; the FCC, CE, VCCI and RCM marks it lists are compliance marks, not durability standards.

Frequently Asked Questions
Singular Expert Insight
The interesting thing about the 2026 relaunch is that it makes the older stock look better, not worse. A T7 and a PRO Plus at 256 GB carry the same speed classes, near-identical read speeds and the same six-proof claims — but PRO Plus is warranted for ten years and T7 for three. Where T7 clearly wins is consistency: Samsung applies U3, V30 and A2 to every capacity in the line, which removes the trap that caught buyers of the 64 GB EVO Plus. Our practical advice: if the prices are close, take whichever has the longer warranty; if you want the card that will still be sold in two years, take the T7. Browse our SD and microSD card range, or a card reader if you want the rated speed on a laptop.
Buyer’s Guide
Buy it if
You want Samsung’s current mainstream microSD at a serious capacity, with the full U3 / V30 / A2 set, for a phone, tablet, handheld console or action camera.
Skip it if
You want the longest possible manufacturer cover — the outgoing PRO Plus and EVO Plus carry 10 years against this card’s 3 — or the card is going into a dashcam or CCTV recorder.
Also consider
T9 at 200 MB/s if you empty the card through a fast reader, PRO Plus or EVO Plus while run-out stock lasts for the 10-year term, or PRO Endurance for a recorder.
