SanDisk 128GB High Endurance Video MicroSDXC Card with Adapter for Dash Cam and Home Monitoring Surveillance Systems – C10, U3, V30, 4K UHD, Micro…

Bought this one for my dashcam as previous OEM card failed one day. Unlike the previous card, this one has been going strong for years. These Sandisk cards are very good for such jobs which require durability and greater temperatures range. I do recommend the item.

Pros:

1. Higher than advertised sequential read and write speeds for an endurance rated card
(Advertised: R: 100 MB/s; W: 40 MB/s | Actual: R: 98 MB/s; W: 87 MB/s)
2. Cheap (I got it for 1069 INR)
3. Free 1-year subscription of their RescuePRO Deluxe data recovery software

Cons:

1. Only a 2-year limited warranty. Transcend offers 3 years and Samsung (if you can get their cards from an authorized dealer in India) offers 5 years.

Review:
I needed an SD card to use with my Raspberry Pi 4 computer that will be running non-stop as a home server and I expect to have a fair amount of reads and writes. Low power usage is critical to me so I can’t boot it off of an SSD so a high endurance SD card it is. I did the usual CrystalDiskMark benchmarks on a PC by connecting it over a SanDisk UHS-I card reader and also performed a real-world read/write test for large sequential files and it performs okay but how will it fare in a Raspberry Pi? I didn’t know.

I was already using a regular (non-endurance rated) Samsung EVO SD card with my Pi 4B for a while so I figured I’d benchmark that and replace it with the SanDisk one and compare the two. I used James A Chambers’ TheRemote/PiBenchmarks suite (on GitHub) for the comparison and here are the results:

As I have used it before, I can vouch for it’s quality

My original Thinkware dashcam memory, their own brand, started acting up after six years of daily use. Thinkware and various reviews I read said that their own memories were specially adapted for the job. However, this memory, the High Endurance, worked straight out of the box, well plastic faced card. I cannot comment on longevity but Scandisk has been reliable for me in the past. It is also made for security camera so should be reliable.

Nice product

Very few class 10 U3 speed micro sd cards available at that price point; seller limits the purchase of more than 2 units ; useful for older generation of M1 dome cameras that accept only high speed 32 GB micro sd cards
