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

This microSD card is perfect for my security cameras. Fast write and read speeds, reliable storage, and designed for endurance, which is exactly what I needed. Comes with an adapter, making it easy to use in other devices too. Very happy with the performance.

Excellent huge capacity card which works well with my Kenwood dash cam. Can't comment on how long it will last but good so far.

Samsung SD cards are always reliable, and this PRO Endurance model works perfectly. The recording is very smooth, and 128GB is just the right amount of storage for my needs. Shipping was fast, and the packaging was secure. It works great in my device—definitely a 5-star product!

They are good and price is good

Use this inconjunction with my Viofo dashcam - works great, records about 10 hours of footage before I transfer it out and cleanse it. Quality of the videos is fantastic but more dependant on the dashcam.

No problems after 3 weeks, of course -ask me again in 10 years. It's a PRO Endurance.

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.

These cards are ideal for write-heavy applications where endurance is more important than absolute performance. That isn't to say that the performance of Samsung PRO Endurance cards is terrible, but the throughput and latency tends not to be as stellar as the Samsung Extreme PRO cards, it's a trade-off. However, if you're after a card for writing-heavy use like dashcams, enhanced endurance cards are a sensible choice. One tip, format your new card with the SD Card Association formatter, surprisingly, it often improves performance. It's a free download and easy to find with Google, but be sure only to download from the official SD Card Association site. These work well and don't cost much more than "normal" cards. I have been using one in an RPi 4 container host for about a year without problems, so I'm quite happy with it, and would most certainly buy another for a similar use-case.

Parfait pour ma camera reolink altas pt ultra!

Ürünü SkyDigital satıcısından aldım Estonya merkezli bir şirket görünüyor ancak Almanya'dan direkt paketlendi. 5 günde Türkiyeye ulaştı fotoğraf ekleyebilseydim eklerdim ancak fotoğraf ekleme yerini göremedim yorum kısmında o yüzden hız testlerinin özetini aşağıya yazıyorum alacak arkadaşlar için referans olsun. Bu arada ürün filipinler üretimli orj samsung çıkışlı paketi vs. düzgün ve kaliteli sahte bir ürün izlenimi vermedi bana. Crystal Disk Mark ile 5 sekansta 4 GB data ile test yaptığımda okuma yazma hızları aşağıdaki gibi çıktı. Okuma 90 MB Yazma baya hızlı atıyor ancak uygulamada yazma hızı görüntüleyemedim windows üzerinde dosya atarkende kaç hızla attığı görülmüyor ama 40 50 mb lar iler atıyor sanırım.

I use this memory card in my dash cam. It works great! I pulled the card the other day and found almost a years' worth of video.

Excellent microSD card, especially for dash cameras. Very reliable and clearly built for continuous recording. No dropped frames or errors so far, even with long recording sessions. Stable performance, good write speeds, and solid durability. A high-quality product that gives confidence for 24/7 use. Highly recommended for dash cams and security cameras.

I purchased the Samsung PRO Endurance 256GB microSDXC UHS-I U3 card in March 2025 for my BlackVue DR770X 2-Channel Dash Cam, and after six months of continuous use, it has exceeded all expectations. This card is purpose-built for high-endurance applications like dash cams, and it delivers flawless performance. The card has been running in my BlackVue DR770X without a single compatibility issue. It handles constant video recording, overwriting, and read/write cycles with ease, maintaining its advertised speed of 100MB/s. The 256GB capacity provides ample storage for extended footage, making it ideal for long drives or continuous monitoring. Compared to the official BlackVue 256GB microSD, this Samsung card is a steal at roughly a third of the price on Amazon. It offers (near) identical performance and reliability, making it a no-brainer for anyone looking to save without compromising quality. The included adapter is a nice bonus for easy file transfers to other devices. I highly recommend the Samsung PRO Endurance 256GB microSD for anyone needing a durable, high-capacity card for their dash cam or similar device. It’s been a perfect fit for my setup, and I’m confident it will continue to perform reliably.
