Sony TOUGH-M series SDXC UHS-II Card 128GB, V60, CL10, U3, Max R277MB/S, W150MB/S (SF-M128T/T1)

Great card. I’ve purchased a few of these to use in the double card slots of my Panasonic cameras (G9 and G9ii). They work great, seem to write quickly, and I’ve never had an issue with them. Have tested the “toughness” of these, but they seem pretty durable.

I’ve finally stopped worrying about my SD cards since switching to the Sony Tough series. These things feel solid as a rock—they have this monolithic, one-piece build that does away with those flimsy plastic ribs and the tiny write-protect switch that always seems to snap off on other cards. It’s such a relief not having to worry about a little piece of plastic jamming my camera slot or failing right when I need to offload footage. The transfer speeds are fast enough to keep up with everything I throw at them, but the real win is just the peace of mind knowing the card itself isn't the weakest link in my setup. Even the M series are great value for money. I use these in my X-T5 and X-T30II, no complaints. Ditched all my Sandisks for these.

Brutal build quality. You can feel it’s heavier and made from a single solid piece — super strong and premium. Fast, reliable, and very sturdy. At first it was a bit tight to insert, but the manual also mentions this, and after a few uses it became completely smooth. I love this card.

This is my first Sony TOUGH SD Card and I will not be switching anytime soon. This is an excellent SD card with an incredible speed to read and write. Very durable and well built. I use it on my FX30 and they pair perfectly. Great SD card!

Fast read/write speeds and ultra-durable build. Handles 4K and burst shooting like a pro. I originally purchased this card in 2019, and it worked perfectly for about three years. In 2022, it started to show some performance issues. Fortunately, Sony had an exchange program for this specific series, and they replaced it at no charge. The replacement card has been flawless and still performs like day one. Excellent support from Sony and a very solid product overall.

superb performance

Should have known I would get the one affected the known corruption issue - the second time this has happened with Sony cards on Amazon! Now I have to go through the hassle of RMAing the stupid thing and waiting for that whole process to complete. Out of all the things I've ordered lately, this is the single item that arrived on-time, so thanks for getting this defective item out so quickly! * * * 9/14/2020 Update... Now that the card has been replaced, I can comment on its actual performance (incidentally, dealing with Sony on the return is pretty straightforward and took about 11 days to complete, the bulk of the time being lost while the package sat around at a FedEx facility for 5 days with no movement whatsoever). The card itself performs as advertised and works very reliably on a GH5 recording in 400/MB/s All-I format, even if the fit in the card slot is ever so slightly tight. The card itself does feel quite stout, almost as if the shell is like a metallized plastic or ceramic material, feels heavier, and sounds different than a regular plastic SD card if dropped on a table (weird thing to notice, I know, but there it is). I have a an assortment of these Sony UHS-II cards, some of which have supposedly been affected by the file corruption issue, but none of which ever failed in actual use, and all of which have since been replaced out of an abundance of caution. Except for the hassle of having return those effected by the recall, I think these UHS-II cards by Sony are worth the cost given the price. The question is, though, do you really need a ruggedized SD card that's 18x stronger than other cards that's also IP68 rated? Probably not, but for those shooting in harsh conditions or who constantly fumble their SD cards into the ocean or your aunt's famous piping hot lasagna, this might well be the card for you. For anyone else, however, the regular version at the same speed rating may work just as well (and the 120MB/s and 100MB/s cards from Sony do equally well in a GH5 recording All-I, just so you know). To be completely honest, even though I needed a large SD card, I purchased this particular one mainly out of curiosity. The way I figure, if I happen to be filming during a flight that crashes into the ocean, the FAA can probably recover the card from the depths to help determine what went wrong, so it could be money well spent!

These are solid, fast cards.
