Transcend 2 GB SD Flash Memory Card (TS2GSDC)
Capacity: 2 GB
I bought this specifically because I needed an older, standard SD card (not SDHC) for compatibility reasons with an older device, a KORG M3. This 2GB Transcend card worked perfectly right out of the box. It is exactly as advertised, and the device recognized it instantly. If you need a true legacy standard SD card, this is the one to get. ... show more

Perfect for TASCAM Model 12-24 multitrack recorder.

I have a Tascam Model 24 multitrack mixer. It uses SD cards for recording. However not just any SD card will work. The Transcend 300S (TS256GSDC300S) is the one I use. In fact, I've bought it twice now. It works with the mixer flawlessly. No latency. The Tascam Model 24 immediately recognizes the card, formats it and then it's ready to record. I'm doing this review to help myself remember the steps in arming the mixer for record. I only use it once or twice a year so I always forget how to do the steps. So this is for my future self. Self, in order to record to the SD card you: 1. Create new song by pressing MENU then NEW SONG on the jog wheel (name it if you wish). 2. Press MENU again to get back to 00h00m00s screen. 3. Arm the track or tracks you want recorded. 4. Finally press RECORD button. Voila! Now back to everyone else. The Transcend 300S can record all 24 tracks from this mixer with ZERO issues. I've recorded several 2-3 hour shows and it works just as you'd expect. Each track shows as an individual WAV file when you transfer from the SD card. I record in 16it 44.1khz. Again, it will record all 24 tracks for hours without a hiccup. I'm not too concerned about the read speed to my PC. The card states up to 100MB/s. It works with my Tascam mixer, and that's enough for me. 100% recommended. ... show more

Works perfect on GameCube for booting swiss (with partition adjustments, read below)
Capacity: 2 GB
So I'm using this on my GameCube console to boot swiss. I noticed some reviews stating it will work, while others said doesn't work at all for this purpose. I will say this did not work as formatted out of the packaging. Here is the trick I used to make it work (note simply formatting to fat 16 or 32 will not fix the problem, it's a partition ID setting you have to change using a special program, not windows format utility!!! -Search for this program and install free standard edition: AOMEI Partition Assistant Standard Edition -Insert your new Transcend 2GB sd card and launch AOMEI. -Identify the correct "disk" and right click the drive letter where it says (example: G: "name of sd") then hover to Advanced, and click "Change Partition ID Type". Make sure you are right clicking the SD and not another one of your hard drives by mistake! -Click the drop down menu and select "0x0B FAT 32" then select ok. -You will be returned to the main AOMEI screen. Click the APPLY button on the very top left corner, and and confirm you wish to make the changes. -Once this is complete and you get a success message, right click the sd card again and select "Format" -Enter whatever you like in Partition Label, I called mine SWISS -Select FAT32 under File System -I chose 16KB under Cluster Size (only one that worked for me) then click ok. Once again you'll be returned to AOMEI main screen. -Click APPLY in the very top left corner again and confirm. Once you get success message you're done! The partition ID was corrected to one the GameCube and SWISS or Action Replay disk will understand. -Finally, copy swiss folder contents onto the SD card and refer to emukidid's instructions on GitHub website with help on loading proper files on SD for successful booting. I was close to returning the memory card until I stumbled upon these settings in AOMEI, so glad I was patient and did some deep troubleshooting! I use action replay disk to boot swiss off this Transcent 2GB memory card with no issues now. It sounds tough but really isnt! WARNING- I do not guarantee this will work for everyone, it worked for me so this is just a tip on how I got mine to work and prevent frustration of returns and buying another card when this one was just partitioned differently than the others!! If done wrong, this could corrupt your new SD card so please understand this advice does not come with warranty, promise, or guarantee, I'm just tying to help others any way I can that are confident in giving this a try understanding the potential consequences of having to make a return anyways or losing the cost. Thanks and good luck out there! ... show more

Fine card, but old class
Capacity: 128GB
Be aware that some of the write speed info on this page is for the newer card class. Using the exact same card reader, another card which made similar write speed claims was doing about 35MB/s, and this one does about 20. It's not bad, and Transcend makes reliable cards, but they currently want almost as much for this as for the newer version. If I had known that, I would have bought the new one for not much more. ... show more

Works great for older devices, perfect for C-PAP machines
Capacity: 2 GB
Review Image by Jern
Review Image by Jern
As others have noted, these are great for devices which cannot format or handle the memory size of more modern SD (SDHC + SDXC) cards. Most importantly for me, these work with the Remstar PR System One C-Pap machines. From what I've read they use the same technology as most other C-PAP devices, so if you have another model you can purchase these with a high level of confidence. If you have an older device of any kind there's a couple things to keep in mind: In this kind of a scenario transfer speeds are rather irrelevant, as the speed of the SD card is limited by the older SD controller. If your device came with standard SD cards there's a high likelihood you'll be capped at 2GB and have to buy these "Standard SD" devices. However, in some instances you may be able to perform a firmware update to allow SDHC cards to be accepted, which you might want to consider if it's for use in a camera or something which would benefit from the higher capability. Don't use a price per GB comparison: Some have complained about the price- noting that for example a newer Sandisk SDHC 32gb model is currently ~ $13. So, why pay $10 for a 2gb? Seems imbalanced, right? Wrong. These reviewers aren't getting it. The older SD technology isn't really in production and there's a small market for it (really just older device compatibility) so we aren't comparing apples to apples here. Take a look at what new blank VHS tapes are going for. I shouldn't compare that to the price of blank DVD's. Sony 6T120VR 120-Minute VHS 6-Pack (Discontinued by Manufacturer) Comparing apples to apples, this Transcend 2GB currently at $9.99 with prime shipping is the best deal on amazon by about $5 currently for the Standard SD cards. If you need these for a device you think you will be using for some time to come, it might be wise to stock up. Anyhow, the bottom line is that for an older device this item is about as good as it's going to get. You can check your product manufacturer's website for updated firmware, but if you are not technically inclined and want a zero-headache solution just pull the trigger already. ... show more
