There's an extremly low strain on a SD card when used in a scanner. You can buy the cheapest ones. SD cards in a scanner doesn't wear out from use. When you read the user review on Amazon from both normal and endurance types they seem to fail randomly and there are several that write that their endurance ones failed more often but are probably just a coincident. So it probably doesn't matter which ones you buy. If you are unlucky it will fail regardless if it is a standard one or extreme or high endurance. The important thing are to have one backup on you with a copy of the current programming that are in the scanner.Yes why are we using them in scanners? Extra money to spend plus ther cheap on Amazon.
I don't think people believe that enabling recording to SD card in the scanner does not include actually writing to the card. I speak about a non replay and record scanning mode, that probably are the most used mode. Even if the replay are always on it would be impossible to wear out a SD card from the shear number of writes to one sector even in a small 4GB SD card.The scanner writes to the card with every transmission unless you disable replay and recording
/Ubbe"SanDisk SD cards have an endurance specification for each sector of 100,000 writes typical (reading a logical sector is unlimited).
Therefore, extremely heavy use of the card in cellular phones, personal communicators, pagers and voice recorders will use only a fraction of the total endurance over the device’s lifetime. For instance—it would take over 10 years to wear out an area on an SD Card based on a file of any size (from 512 bytes to maximum capacity) being rewritten 3 times per hour, 8 hours a day, 365 days per year."
OK, so it is only 10 years of continuous 24h recordings as the guaranteed life time. Switch to a standard type 32GB size and it's 80 years. When the card controller detects a cell that doesn't verify a write succesfully it will mark that cell as bad and not use it again.And tbe spec you quoted is for high endurance cards. Standard cards are rated for ~5000 writes to a sector before failure.
Correct, when I was serious about photography, I had two cards die, neither had taken more than 10,000 photos...Card failure is a recurring topic among digital photographers; losing a few hundred wedding shots when a card fails can make grown men cry. It's absolutely not a Uniden-only thing.
And most us folks who are serious/professional photographers would not consider a camera that does not have dual slots. The real high end use XQD cards because they have a better life span, with the SD card being a backup.Some pro cameras have two card slots, and allow files to be written to both simultaneously for that reason.
Thankfully in both cases they failed when I first went to use them after downloading photos off them. This was on different brands of cameras, about 6 months apart.Some pro cameras have two card slots, and allow files to be written to both simultaneously for that reason.
I remember seeing at least a few posts where someone has a problem SD card and will try to re-format it in a card reader to no avail. Also you'd think that a good number of folks experiencing SD card failures would have sense enough to clean the contacts before saying there is a problem.Uniden have a history of bad quality in their connectors from BC780's display ribbon connector to todays rotary encoders and what I suspect happens to most Uniden users are that the SD card sits in the scanner and are not moved for a long time and starts to get a bad connection between SD card and the scanners connector. Then the user gets a new SD card and at the process of switching SD card the surface of the connector are freshen up and scanner works again. But it probably would work anyhow if the original SD card where removed and reinsterted again. Most of those suspected problematic Uniden SD cards probably works just fine when tested with a computer SD card interface and can be used without any problem in other devices.
