Sandisk Announces SD Card For Surveillance

They say it's good for 10,000 hours of 1920x1080 at 26Mbps to one device. I have no idea how they came to this conclusion. It comes in 32GB and 64GB. It's rated from -13 degrees to 185 degrees Fahrenheit. It's waterproof, shockproof, and x-ray resistant. A photography store with which I am familiar is taking preorders for $25 for the 32GB and $50 for the 64GB. Best of all, it comes with 1 year of access to RescuePro Deluxe, which is a real solid data recovery program, just in case.

Good find. Thanks!

Btw, for background - Axis Edge Storage And Camera Companion Is Unstable.

Now I am trying to understand this:

"They say it's good for 10,000 hours of 1920x1080 at 26Mbps to one device."

10,000 hours is 416 days. So that means 416 days of recording? Essentially impossible with 64GB. So do they mean the card will die / burn out / have problems after a little more than a year?

Also, Ari, where did you get the 26Mbps? I am struggling to find it on those links.

Mouse over the asterix that follow the bullet point that says "Up to 10,000 hours of Full HD video recording (64GB) and up to 5,000 hours of Full HD video recording (32GB)" and it says Based on Full HD (1920x1080) video content recorded at 26 Mbps to one device; Results, video support and performance may vary depending on host device, file attributes and other factors.

Then they must mean 10,000 hours lifetime of the card because recording at 26Mb/s won't even get a day at 26Mb/s or anything close to that.

Yes that's what they mean. It 'stands up to' 10,000hrs:

Stands up to 1,000s of hours of recording SanDisk High Endurance Video Monitoring 64GB microSDXC card will stand up to 10,000 hours of Full HD video recording** in your dash cam or home security system, providing a durable, reliable record of what happened at home or on the road. The 32GB card will stand up to 5,000 hours of Full HD video recording**.

you know SUH, standup hours....

How do you market a card that is only rated to work for a little over a year? This is not a feature, but a flaw.

I would agree that it is a flaw since you should expect to get years not a year out of a card? For people that are using SD cards for edge recording, do you see SD cards consistently dying after a period of time? If so then what length of time do you expect to get out of them? I guess mention of the brand would be helpful. Is there a discussion on this already?

Most people have only been using SD cards with IP cameras for a short period of time, so it's hard to get a lot of data points but there are definitely some people reporting using cards for multiple years.

What I really don't understand is the point of making a surveillance specific SD card and then only rating it for ~14 months use?

It's based on how many times the cells get overwritten. One would expect that 13 Mbps might get 2 yrs. What's a realistic edge stream 5Mbps? 5 years. Why they use 26, I have no idea. I'll look to see if they break it down further somewhere.

Could be but, if so, SanDisk sucks at marketing. Who picks an incredibly unlikely adverse condition to benchmark the longevity of their products?

SanDisk responded to our request and is working on providing feedback.

It's because they're using FullHD = 26 Mbps. Probably some guy from the camcorder division worked on it.

Nobody told them we squash the s**t out of our video before we record it. ;)

I think this calls for a test! While I have never made use of edge storage using SD cards I have spoken to folks that have... and I have yet to hear any positive experiences. I would be eager to use it if there was a bit more positive feedback. Perhaps this is the product that makes edge storage a bit more reliable.

Thinking long term 10,000 stand-up hours doesn't seem like much if that's the same as MTBF. Conventional platter hard drives rate their MTBF in millions of (greatly inflated) hours.

I have experience using the SanDisk Extreme and SanDisk Ultra cards for edge storage. A general rule would be to use at least a Class 10 card. The higher speed on the class 10's worked really well...however, only SanDisk cards worked.

There were many issues with other makers cards (Kingston, etc) using the same class 10 media. It was unclear what the differences were between them, but the Kingston cards had a ton of read/write errors and didn't work well for things like exacq edge server.

As noted the card 'lifespan' is generally calculated in terms of full read/writes. Therefore it stands to reason why the larger capacity cards naturally have a longer life span rating. Larger capacity = longer time to reach full overwrite = better longevity.

However, as John mentions, there simply aren't enough data points in the market today for multi-year longevity testing.
