The high capacity microSD, aka microSDHC, are those microSD cards with capacities in excess of 2 gigabytes that adhere to the SD Association's standard for high capacity cards. What does the Class Rating mean? What does that "C" with a 4, 6, 10 or 2 inside it signify?The class refers to the data transmission speed (DTS) of the card, its ability to accept and send information from the device in which it is installed. If you know how quickly a device can read and write to the card you can more closely match the card to it. There is no sense in putting a Class 6 card in a device that writes so slowly that a Class 2 card is sitting there twiddling its virtual thumbs waiting for bits.
As a rule of thumb the class of a card is the sustained data transfer speed (DTS) in Megabytes per second (MBS)If you have a device that is capable of fully utilising a CLASS 6 card and you saddle up a CLASS 2 you will impair its functionality. In a camera that will slow down how quickly you can take the next photo. In a device that is capable of transferring 1.5MBS if you install a CLASS 6 card you are wasting your hard earned money. Prices for a CLASS 2 and a CLASS 6 device can be as much as 100% premium for the CLASS 6 over the CLASS 2 for the same amount of storage.
Class ratings also apply to the full sized SD cards.CLASS 2 SDHC Card CLASS 2 icon

The images are from Kingston products. The CLASS icons are not exclusive to any particular manufacturer but are used across the industry and are trademarks of the SD Association. As can be seen the symbol is a san-serif C with the numeral of the class rating inside.When shopping on eBay for SDHC or microSDHC know your class. If a seller has obscured the class icon or does not let you know from the description what class he or she is selling either ask or move on.the difference is the transfer speed. Class 4 can go upto 5MB/s whereas Class 6 touches a high of 20 MB/s.
That class number has to do with the card's 'write speed'. Generally higher is better and some devices (like cameras) may require you to have a minimum class.

Yes... Absolutely! I also have a JMCR SD MMC SCSI Disk Device card reader & I tried putting a 16 GB SD card in it today... it wouldn't format it or read it (at first)... Now my JMCR SD MMC SCSI Disk Device card reader DOES read SDHC cards!!! (Including the 16 GB one it couldn't read a little while ago). The problem is finding the right software online... it isn't easy. If you navigate to Control Panel > find & start Device Manager > Under Memory technology driver ... you should see it listed as "JMicron PCIe SD MMC Host Controller", "JMicron PCIe xD Host Controller", & a few other JMicron devices. You could try updating those drivers. The point is that it is a JMicron Memory device... so if your computer manufacturer keeps an updated list of drivers (such as Toshiba does) you should be able find it under a description related to this. To do that you have to: First locate your model number, serial number, and part number (on bottom of laptops or some sticker on any device). Then find your manufacturer's driver source (they should be free). Then find this exact driver/software for your exact device there. Install it and then try it. Option 2 would be to find and use a driver update program. Option 3 (Might not be compatible with your system) you could attempt to use the one from Toshiba even if yours isn't a Toshiba... i.e. there is a USB formatting program that works on most systems. Just be prepared to restore your system if this does install on a non-Toshiba device & turns out to be harmful.... and use this only as a last resort at your own risk. This might damage your hardware / device... so it's entirely up to you.

SDHC memory cards are the advanced version of SD cards. Sd holds from 8 MB to 4GB of memory where as SDHC starts off at 4 GB and goes up. The data transfer rate is much higher with SDHC also but you have to make sure the digital camera accepts the card by looking in your manual before purchasing.
Yes, the LG Lotus does support micro SDHC memory cards.The difference between micro SD and micro SDHC is that "HC" (high capacity) goes beyond the 2Gb limit of micro SD. As such there is a different format. SD is FAT16 and SDHC is FAT32. From what has been documented, the LG Lotus can support up to 12Gb. No one makes a 12Gb micro SDHC card, so it might be a misprint... or a 16Gb card may only provide up to 12Gb of usable memory in the Lotus. In any case, that's a heck of a lot of memory for such a device!As an aside, you may also be interested to know that the SDHC cards have a speed rating. Class 2: 2Mb/sec; Class 4: 4Mb/sec; and Class 6: 6Mb/sec. Keep that in mind when purchasing your SDHC card. Obviously, the faster the better but also the more expensive.
SDHC is a little more relaible.
The Transcend SDHC memory cards are very good, and use the same memory supplier and many other brands.
A SDHC memory card is very popular among consumers. One noted benefit of this product is the small size of the memory card in relation to other cards.
The Transcend 16 GB SDHC is large, but you can also get 32 GB SDHC cards for your camera.
Yes microSD is a physically smaller card than a SDHC, which is a High-Capacity version of an SD card. anonymous@oola.com
SD/SDHC memory cards only.
SDHC is currently the fastest type of memory card.
Removable Memory (16GB) SDHC. So yes you can use a SDHC memory card with this phone.
Yes.
