Samsung PRO Ultimate microSDXC 512 GB — 200 MB/s read, Class 10 / U3 / V30 / A2

512 GB microSDXCClass 10 / U3 / V30 / A2Read 200 MB/sSD adapter included

The MB-MY512SA/WW is Samsung’s PRO Ultimate microSDXC card in 512 GB. Samsung rates it at 200 MB/s sequential read and 130 MB/s write, with the Class 10 / U3 / V30 / A2 marks that matter for video recording and for running apps directly from the card. The SA in the part number means an SD adapter is in the box, so the same card also drops into a camera or a laptop SD slot. Note that 512 GB is the largest PRO Ultimate microSD Samsung makes — the line runs 128, 256 and 512 GB only, with no 1 TB. 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 200 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

✓ Long 4K and 8K shoots in an action camera or drone
✓ A camera that takes full-size SD, via the bundled adapter
✓ A large game library on a handheld console
✓ Android phones and tablets that run apps from the card

Key Features

 
200 MB/s read — the fastest microSD Samsung makes
PRO Ultimate is the top of Samsung’s microSD range at 200 MB/s read and 130 MB/s write, identical at every capacity in the line. Read the compatibility note above before budgeting on that figure: it needs a DDR200-capable Samsung reader.
 
512 GB is the top of this line
Samsung makes PRO Ultimate microSD at 128, 256 and 512 GB and stops there. If you see a 1 TB PRO Ultimate microSD advertised, it does not exist — it will be a different line.
 
Rated to 2 m of water, not 1
A small but real difference from PRO Plus and EVO Plus, both of which Samsung rates to 1 m. PRO Ultimate is the only microSD line Samsung takes to 2 m for 72 hours in saltwater, and the only one rated to 5 m drops rather than PRO Plus’s 1.5 m.
 
A2 and V30 — the two marks that matter
A2 covers random access when Android runs apps from the card; V30 guarantees a sustained 30 MB/s write floor, which is what camera and drone makers specify for 4K. A floor rather than a peak, which is exactly why it is the useful number.
 
SD adapter in the box
The bundled adapter turns the card into a full-size SD, so one card covers a phone, a drone and a camera. It carries its own shorter Samsung term: 1 year, against the card’s 10.

Warranty
Warranty 1-Year Warranty (Singular)
Samsung Term Samsung publishes a 10-year limited warranty on the card and 1 year on the bundled SD adapter. Samsung’s own term is stated here for information; Singular’s direct warranty is 1 year.
Important Exclusion Samsung’s memory-card warranty expressly does not cover dashcam, CCTV, surveillance or other write-intensive continuous-recording use. For those, a PRO Endurance card is the correct product.
Not Published by Samsung
Endurance / TBW Not published. Samsung publishes no terabytes-written or lifespan figure for this line. The 10,000 figure above is insertion cycles.
Random IOPS Not published. The A1/A2 marks imply SD Association minimums, but Samsung publishes no IOPS numbers of its own.
Other Omissions NAND type and layer count, controller, MTBF and UBER are not published.

Frequently Asked Questions

Will I really get 200 MB/s?
Only through a reader that supports Samsung’s DDR200 mode. In a phone, camera or standard laptop slot you will see roughly 104 MB/s, the ceiling of the standard UHS-I bus. That is the bus, not a fault with the card.
Is there a 1 TB PRO Ultimate microSD?
No. Samsung’s datasheet lists this line at 128, 256 and 512 GB only. If you need 1 TB in a microSD, look at PRO Plus or the newer T7 line, both of which go that high.
How does it compare with PRO Plus?
PRO Ultimate reads at 200 MB/s against PRO Plus at 180, is rated to 2 m of water rather than 1 m, and survives a 5 m drop where PRO Plus is rated to 1.5 m. Write speed, speed classes and the 10-year warranty are the same.
Can I use it in a dashcam or CCTV camera?
It will work, but Samsung’s warranty explicitly excludes dashcam, CCTV, surveillance and other continuous-recording use. Those rewrite the same blocks all day and need a PRO Endurance card, which is built and warranted for exactly that.
How long will the card last?
Samsung publishes no endurance or terabytes-written figure for this line, so we will not invent one. The 10,000 figure in the specifications is insertion cycles — how many times it can be plugged in and out.
Singular Expert Insight
Worth knowing when you compare this against newer stock: Samsung renamed its microSD range in 2026, with the T9 line replacing PRO Ultimate and T7 replacing the mid-range. T9 is also 200/130 MB/s — but it ships with a 3-year manufacturer warranty against PRO Ultimate’s 10, and T9 tops out at 512 GB while T7 goes to 1 TB. So at this capacity the older badge is not the weaker buy; on warranty it is clearly the stronger one, at identical speed. Choose on the reader you own and the warranty term, not on which name sounds newer. 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 fastest microSD at its largest capacity, you shoot 4K or 8K, and you want the SD adapter so one card covers a camera too.

Skip it if

You are buying for a dashcam or CCTV recorder (PRO Endurance is the right product), or the card will only ever sit inside a phone, where EVO Plus gives you most of the experience for less.

Also consider

PRO Plus at 180 MB/s for less, T9 if you would rather buy into Samsung’s current line, or PRO Endurance if the card is going into a recorder.
