Good card for dash cams
February 15, 2018
---> I have the 32GB capacity model
This card tests as legitimate capacity. If you're considering buying these for a dash cam, I would highly recommend them. They're inexpensive relative to other dash cam cards (at the time of posting at least), and they say specifically on them that they are made for dash cams.
Note: do not get a low quality memory card for dash cams. Cheap cards fail quickly and unexpectedly and if you get into an incident with a failed card you're in a bad place.
--- Speed ---
On the package it says read/write speed is 25MB/s, but I get more like 40MB/s. This is more than enough for any modern dashcam (although it may not be enough for some Real 4K action cams). If you're using them in a mobile device like a smartphone this card has a relatively quick random read/write speed too (most cheaper cards are 1/3rd this speed). It is faster at random read/write than many cards in its price class (small files like system files) but not as fast at writing big files (photos, videos) where other cards at this price can read/write up to 90MB/s. For a dashcam or security camera these speeds are more than sufficient.
--- Longevity ---
These cards claim 5,000 hours of recording at 25MB/s. Most dashcams that are 1080p film at 12 - 16 MB/s. So expect 5,000 hours of recording on average; more if you set your cam to 720p, less if you have a 2.7K cam like the Viofo A119. I've only had these cards for a couple weeks myself at the time of writing, thankfully all are still working. Other users on Dashcamtalk report these cards as being reliable in the long term.
--- Downsides ---
There's no standard or micro SD case included (only a standard SD adapter). So if you want to keep this around as a backup card you'll need a case. Sandisk's blanket warranty clause still states that they don't warranty any of their cards when they are used in a video monitoring situation (dashcam, security camera, etc).
--- Other Notes ---
These cards also claim to be temperature proof (important for dash cams because it gets hot under the windshield).
--- Conclusion ---
If this card is less expensiv than other highly reviewed endurance cards like Transcend High Endurance, Adata Premier Pro or Lexar High Endurance, then get it! If one of those other cards are less get them instead. The cos t on these things fluctuates pretty heavily depending on the day so do your research before jumping. But if you are running a dash cam it is definitely worth it to get an endurance SD card.
