12 best memory card for mp3 players

Memory cards for MP3 players are essential accessories that allow users to expand the storage capacity of their devices and store more music, podcasts, and other audio files. Here's what you need to know about memory cards, specifically micro SD cards, for MP3 players:

  1. Micro SD Cards: Micro SD (Secure Digital) cards are a popular type of memory card commonly used in MP3 players and various other electronic devices. They are compact, durable, and available in various storage capacities, making them ideal for expanding the storage of MP3 players.

  2. Storage Capacity: Micro SD cards come in different storage capacities, typically ranging from a few gigabytes (GB) to several hundred GBs or even terabytes (TB) in some cases.The choice of capacity depends on your specific needs and how much music you want to store on your MP3 player.

  3. Compatibility: When purchasing a micro SD card for your MP3 player, it's crucial to ensure that the card is compatible with your device. Some MP3 players have specific requirements regarding the type and capacity of memory cards they can use. Check your device's user manual or manufacturer's website for compatibility information.

  4. Class and Speed: Micro SD cards are classified by speed class, which indicates their data transfer rate. Classes like Class 4, Class 10, UHS-I, and UHS-II represent different levels of performance. Faster cards are better suited for tasks like recording high-quality audio or video. For storing music on an MP3 player, a Class 10 or UHS-I card is typically sufficient.

  5. File Format: Most micro SD cards come pre-formatted with the FAT32 file system, which is compatible with a wide range of devices, including MP3 players. However, it's essential to ensure that your card's file format is supported by your MP3 player. Some devices may require reformatting to a different file system.

  6. Reliability and Brand: It's advisable to choose reputable brands when purchasing micro SD cards to ensure reliability and data integrity. Well-known brands often offer warranties and customer support in case of issues.

  7. Storage Management: When using a micro SD card with your MP3 player, you can organize your music files into folders and manage your content more efficiently. This helps you keep track of your music library and access specific songs or albums easily.

  8. Backup: It's a good practice to regularly back up your music library from your micro SD card to a computer or another storage device to prevent data loss in case of card failure or accidental data deletion.

In summary, micro SD cards are valuable accessories for MP3 players, allowing users to expand their storage capacity and carry more music on their devices. When choosing a micro SD card, consider factors such as storage capacity, compatibility, speed class, and reliability to ensure optimal performance and a seamless music listening experience.

User questions & answers

Question: how do I know if I need the new version
Answer: If you desire faster transfer speeds otherwise no need for new one
Question: Does this work with the new Amazon Fire Tablet
Answer: I don't know about this specific card, but the Sandisk Extreme Plus (red top stripe like this, but gold bottom instead of grey) 128 GB, V30, XC I, U3, A2 cards I have (multiple from different purchases but the same model), formatted to exFAT with 128 kb allocation units, have not worked at all in my kid's Kindle Fire 8" model. I have not tried them in other kindles, but the model I just listed does NOT work. Are you inferring that I'm pissed off, yeah. That is a fairly higher end card. Fast, sizable. meets all the common standards, stock formatted in about the most common configuration for cards. Meets everything Amazon says is supposed to work that I can find (by the way, finding info on what is supposed to be fit-able inside my kid's fire table has been a pain, Amazon could do a damn better job of documenting their models and what is supposed to work with them). And, a big goose egg. What a waste. No idea why the Amazon tablets suck so much. This is simple software stuff that should have been fixed about 8 years ago with their 2nd or 3rd model and rolled forward from then on at no extra cost to the consumers (who deserved a working storage driver in the first place. And yeah, all the SD cards work fine on every windows machine and the GoPros I have used them on, just the kindle is incompetent with it. Maybe the slot on the kindle is borked? Nope, it can see at least two other microSD cards just fine. Really retarded.
Question: What is the actual usable size of this card
Answer: I have the 128gb card and use it for an android phone (I have an LG G Stylo). It had to be formatted first and then I got a total of 119gb of actual usable memory. Hope this helps.
Question: Does it work with iPhone
Answer: Just add it to a card reader with a lightning connector like the Massdata Lightning iFlash USB SDHC Micro SD OTG Card Reader For IOS 9 iPhone 5 6 6S Plus iPad PC & Android and it works with both iPhone and iPad after downloading the iStick app from the App Store.

User questions & answers

Question: Does this work in a smart watch
Answer: You do not need the adapter for the tablet. Just use the card only. With screen facing up and that SD card facing up push into slot until it clicks. It is in place and ready for use. The adapter is only used if the slot is too big for an SD card by itself. https://www.youtube.com/watch?v=MkCVcit7mEQ
Question: does this work with keychain hidden camera for Brickhouse
Answer: No, I don't think so. I have no personally tried it but this is the lower end version (class 4) of the SD cards, the 3ds requires one more optimized (class 10 'high def') made for digital cameras. Nintendo has a list of SD cards compatible with the 3DS on their website. Just copy and paste the whole model number into a google search and look around for a good price.This is the SanDisk 32Gb SD card that works with a Nintendo 3dshttp://www.amazon.com/SanDisk-Extreme-SecureDigital-Memory-SDSDX-032G/dp/B004P1V8TM/ref=sr_1_3?ie=UTF8&qid=1406698429&sr=8-3&keywords=32gb+lsd32gbsbna200This is Nintendo's approved list, just copy the whole model number into the search (google or amazon).http://en-americas-support.nintendo.com/app/answers/detail/a_id/517/session/L2F2LzEvdGltZS8xNDA2Njk3ODM0L3NpZC9pYkRyMnotbA%3D%3D

Answer: k case you want to download to computer you'd need the adapter to put the mini into. Also so you could use it at a kiosk for pictures with the adapter
Question: Does this work with a dash cam? I need a TF memory card but don't understand this class thing
Answer: Hello John,Unlike card write speeds that measure maximum performance, class ratings measure the minimum sustained speed required for recording an even rate of video onto the card. The class rating number corresponds to the transfer rate measured in megabytes per second. Class 2 cards are designed for a minimum sustained transfer rate of 2 megabytes per second, while Class 10 cards are designed for a minimum sustained transfer rate of 10MB.
