SamsungPRO Endurance 128GB microSDXC UHS-I U3 100MB/s Video Monitoring Memory Card with Adapter (MB-MJ128KA)

The Samsung PRO Endurance 32GB microSDHC Memory Card has been a perfect solution for my Raspberry Pi project. Since switching to this card, my Raspberry Pi no longer locks up or experiences performance issues. The 100MB/s read speed ensures smooth operation, and the UHS-I U1 rating makes it ideal for continuous video monitoring and data storage. The card’s durability is also impressive, providing reliable long-term performance even with heavy write cycles. It’s a must-have for anyone looking to improve the stability and performance of their Raspberry Pi or similar projects. Highly recommend!

I bought 2 of these and they work well with my security cameras I would definitely recommend seller and product 5⭐️

Bought two of these 256gb u3 samsung pro endurance microsd cards, and after testing found that one card is consistently faster than the other in random read and write speeds, and by a significant margin too (about +50% faster reads and over +100% faster writes). For context, the slower card is very similar in performance to a 512gb u1 a1 sandisk ultra microsd card I own. Sequential speeds on the other hand, are practically identical between the two. Using the microsd to sd adapter card had no effect on performance, so that's good. I should note that the slower card also seemed to not fit as smoothly into its sd adapter as the faster card. Both came in identical sealed packaging so I doubt there's anything suspicious going on, probably just normal manufacturing inconsistencies across individual units, but I feel it's worth mentioning.These cards are true to spec (u3/v30 means approx. 30MB/s sequential writes which is as observed, and are indeed 239 GiB = ~256GB), and as such I have no doubts about the claimed endurance rating advertised at over 140k hours. Some IOPS speed differences may be observed between individual cards so keep that in mind if high application performance (e.g. gaming) is a concern. I purchased these at £31.90 a pop which is a steal compared to sandisk's competing 120k hour max endurance offering that is almost twice as expensive for the exact same capacity and advertised speeds.Conclusion: highly recommended, especially since one of the biggest weaknesses of SD cards compared to ssds and hdds (other than speed) is their comparatively very short lifespans, an endurance sd card is a must for power users that regularly burn through normal sd cards.

Too early to tell how robust these cards are .. allegedly these aren't the fastest of cards, nut I can't fault the speeds when tacking 4K video or rapid raw format 20mp photos.I actually bought it to use in a Raymarine Axiom chart plotter .. a "tough" card from another manufacturer lasted just 18 months before it corrupted £240 of charts.I'll be back to update this review in 5 years .. 🤔😁😎

These High Endurance cards are the real deal and are better than SanDisk and Lexar offerings by a long shot longevity/write cycle wise. I used 32GB MicroSDs for a friend and I to replace our Hynix NAND and we are good to go for a while.This is not my first Samsung memory I own.I have also memory modules for my computer, SD cards and micro-SD cards and the performance and MOST important the reliability of Samsung chips are paramount.Also this one is not affected by the x-ray machines at the airports so, peace of mind!

No issues, works very well. For use in an old Samsung S7.

Bought this microSD card for my Thinkware Q800 Pro dashcam and no complaints so far. Blackvue and Thinkware arguably make the best dashcams in the world however they suffer from MicroSD card compatibility, they both usually only support their own branded MicroSD cards which tend to be stupidly expensive. The 128Gb Thinkware MicroSD card is approx. £89! That's almost £70 more than this Samsung Pro Endurance 128Gb at the time of writing this!! After doing some research I came across many reports which claim that the Samsung Pro Endurance MicroSD cards work with Thinkware dashcams hence I thought I'd try it out, and it worked :)I previously tried using a Sandisk Extreme 256Gb card which failed to work however I later came across a section on Thinkware's website which suggested that only cards up to 128Gb are compatible with the Q800Pro, 256Gb card can only be used with 4k dashcams like the Thinkware U1000. After ordering this product I got told by a friend that the Sandisk Extreme 128Gb (V30 / Class 10) MicroSD card also works with the Q800Pro... although the Sandisk offers faster read & write speeds whilst being slightly cheaper, I'd still recommend going for the Samsung Pro Endurance to anyone buying a MicroSD card for a dashcam given that is appears to have been specially designed for dashcams and monitoring devices.

Bought this for my outdoor camera. Reasonably priced, delivered quickly, and is working as expected, so far.
