Oh How I miss the Memory card
on July 11, 2026
Posted by: Samsunglady510
I remember when these were the best thing to expand your devices memory. 128gb was also so much memory to us back then. But the convenience of running out of memory then grabbing another SD card and changing it out quickly & easily. They were universal and compatible with most devices. They were definitely durable because they were so tiny BUT always having the SD card come with the larger attachment also made it easier. Formatting the memory cards took a little bit of time to transfer to your computer but not as long as wireless phone to phone transfers, But let's face it.... its gonna take forever if you have over 300 pictures and lots of videos. Always wished there was a way to make transferring a quick seamless transfer. It's all wishful thinking though, memory cards were the best feature of all time when it came to expanding the memory and replacing it with a new SD card was so quick! How about we bring back the SD slot for people who want the option and don't use the cloud. And I know we can transfer data between devices, but can we all practice an overall messaging and media cleanup to help speed up the transfer process.
