The microSD card contacts or the internal adapter contacts can get dirty, the contact leaves can lose some of their springiness through use and fatigue, or poor manufacturing, etc. An adapter and microSD card in good, clean condition should behave exactly like an SD card.Īny component of this nature can have marginal performance due to poor electrical contact. The extensions go from fixed contacts where an SD card would have them to springy leaves that rest on the microSD card contacts. The adapter is just a plastic shell that holds some metal extensions for the microSD contacts. But there's an alternate potential explanation. It's possible that all of these reports are wrong based on imagined results or poor measurement. So what to make of this apparently conflicting information? At least some of the reports have come from people with enough technical background to suggest that they wouldn't publish such a report based on nothing but flimsy anecdotal evidence. Other than the production testing performed by the manufacturer, there doesn't seem to be reliable testing to prove that an adapter is or is not capable of slowing down a microSD card's performance. There have been a few, but multiple, reports of performance degradation from the adapter. I found a report of some testing that showed the adapter increased performance a negligible amount, which makes no sense, and they chalked it up to being within the margin of error.
Keltari's answer mentions what appears to be some anecdotal evidence of adapters slowing performance in some specific cases. There is nothing in the adapter that should affect speed. Some of you may have other problems (For instance, flipping the switch on the left side of the SanDisk Adapter, which somebody referenced and I tried, since nothing in the packaging mentioned that switch!) that aren't impacted by your reader, but check your device (camera, reader, etc.) and if it is over a few years old I wouldn't be surprised if it isn't modern enough to recognize an HC card (it may have HC stamped somewhere to indicate it is capable), and you have to decide if you want to dial backwards in terms of storage capacity or bite the bullet and upgrade your device to handle these advanced cards.Eugen Rieck's answer should be correct. So, my two choices are: first, return the 4 gig SDHC microcard and get a smaller card that is not HC, which obviously limits the stuff he can store on his phone, or second, buy a new reader that can handle the newer HC disks. My old (4 years?) SanDisk card reader (Imagemate 8 in 1) is not HC compatible, and so, even though made by the same manufacturer, it CANNOT read the card I bought. One other, critical, distinction is that if it says HC on it you must have a reader that can handle HC. I bought a 4 gig SanDisk microSDHC card, and the store clerk told me the HC was just how they (SanDisk) classify the high capacity disks and nothing else was different. Had to buy a SanDisk microSD card for the phone to hold the music (and also because nobody in town had a Pantech compatible USB cable to transfer the few songs he has). My son just got a phone (Pantech Matrix), and we were trying to transfer his playlist from Windows Media Player to the phone. a prompt came up on my screen asking me to choose which program to run/open the photos on (for me, it was windows media center), and to my relief, all my photos were there! I hope this helps.įirst of all, some of you simply aren't helpful.just return it.indeed! then, after, again, nothing happening, searching forums on other lost memory card-ers, I discovered that there is a very tiny "switch" on the left of the adapter, next to the "S" on sandisc, that must be flipped down in order to "work," or grant photo/media access. then the discovery with inserting the memorycard into the adapter (on my laptop, it's at the front below the touchpad-very sly sneaky place).
more frustration-thinking it must be that I don't have the right "software" to run to access my photos and doing many searches for the "right" software solution. I was keeping the tiny memory card in my phone (LG choc 8500), while plugging the charger cord (which doubles as the usb cable) into my computer. it came in a pack with two different sized adapters that the memory card can slip into, depending on what size is compatible with your computer (i did not know that this is what you do with the memory card). Ok, I finally figured out the dang thing on my computer! I have a 2 gb sandisk memory card.
