Well, we alredy know wat that is ... its a microSDHC card.. but what most us don't see it the class... The 'HC' extension doesn't necessarily mean anything but 'high capacity'..
The class is, however, important.. It defines the speed.. its an easy estimation that class 2 will give minimum 2MBps write, class 4 will give 4MBps write n so on.. read speeds are usually way more than that... now.. If you just buy a class 10 card and use it with an average phone ( say Samsung Galaxy Y) ,you wont get the speeds defined as those phones can not handle these speeds..
Also buy a high end phone (say Samsung galaxy S4 or Xperia Z Ultra) and use a class 2 card.. you get most of your HD videos almost stutter to death.. Moreover as today's smartphones get more camera capability (say 10+ 12MP shots in a second or high-def high-bitrate recording), it is absolutely necessary to get a fast card...
A rule of thumb.. class 4 is the best for mid-range phones.. class 6 is better suited for high end phones..Another specification is UHS-1 which typically costs as much as a class 10 card, is also suited for high end phones..
So mind the class while buying a card.. also the warranty is equally important as MicroSD cards are very likely to get corrupted..5 years manufacturer warranty is good enough..
Dear Mr. Debasish
Micro SD & MIcro SD HC both are same except the memory capability
i.e. upto 4 GB it is called Micro SD while
for the memory 4GB to 32GB it is called -Micro SD HC
It supports C2-00.
first of all, hats off to flipkart!! placed order on the 13th of feb, received delivery on the 15th!! just two days!! the delivery is very efficient, and timely.
about the product, why you should buy this:
1. the price is way lower than what you would get at any shop, vendor or showroom (around rs 500 at least).
2. it is the original product, as it comes with the manufacturers warranty.
3. class 4 is enough for the present handsets available in india, and class 6 and higher will be an overkill.
4. my phone (nokia e5-00) has no problem, and is working without lag with this memory card.
5. the read-write speeds are good, and there is no problem in accessing photos, videos and music on the phone.
I bought this a month ago for my SonyEricsson J108i and is working great. So I gave a new order for the same for my Samsung Galaxy Ace.
Speed of this card is class 4 and my mobile handle it better.
You only need to buy class 6 / class 10 microSD cards if your phone is priced above 20K, and supports data transfer at high speed.
Or if you are planning to use the microSD card with your computer like a mass storage device you can go for class 6 or 10.
About the Micro SD Card's:
Micro SD Card are 3 Types...
1.SD (Secure Digital)
2.SDHC (Secure Digital High Capacity)
3.SDXC (Secure Digital eXtended Capacity)
The first-generation Secure Digital (SDSC or Secure Digital Standard Capacity) card was developed to improve on the Multimedia Card (MMC) standard. The SD cards changed the MMC design in several ways:
Asymmetrical slots in the sides of the SD card prevent inserting it upside down, while an MMC goes in most of the way but makes no contact if inverted.
Most SD cards are 2.1 mm (0.083 inches) thick, compared to 1.4 mm (0.055 inches) for MMCs. The SD specification defines a card called Thin SD with a thickness of 1.4 mm, but they are rare, as the SDA went on to define even smaller form factors.
The card's electrical contacts are recessed beneath the surface of the card, protecting them from contact with a user's fingers.
The SD specification envisioned capacities and transfer rates exceeding those of MMC, and these have both grown over time. For a comparison table, see below.
Full-sized SD cards do not fit in the slimmer MMC slots, and there are other issues that affect the ability to use one format in a host device designed for the other.
2. 2nd Type:(SDHC)
The Secure Digital High Capacity (SDHC) format, announced in January 2006 and defined in Version 2.0 of the SD specification, supports cards with capacities up to 32 GB
SDHC cards are physically and electrically identical to standard-capacity SD cards (SDSC). The major compatibility issues between SDHC and SDSC cards are the redefinition of the Card-Specific Data (CSD) register in Version 2.0 , and the fact that SDHC cards are shipped preformatted with the FAT32 file system.
Version 2.0 also introduces a High-speed bus mode for both SDSC and SDHC cards, which doubles the original Standard Speed clock to produce 25 Mbyte/s.
3. 3rd Type:(SDXC)
The Secure Digital eXtended Capacity (SDXC) format, announced in January 2009 and defined in Version 3.01 of the SD specification, supports cards up to 2 TB (2048 GB), compared to a limit of 32 GB for SDHC cards in the SD 2.0 specification. SDXC adopts Microsoft's exFAT file system as a mandatory feature, although some portable devices rated for SDHC will also accept a 64GB SDXC card if it is reformatted as NTFS instead of exFAT.
The 3.0 specification also introduced the Ultra High Speed (UHS) bus for both SDHC and SDXC cards, with interface speeds from 50 Mbyte/s to 104 Mbyte/s for 4-bit UHS-I bus.
Version 4.0, introduced in June 2011, allows speeds of 156 Mbyte/s to 312 Mbyte/s over 4-lane UHS-II bus, which requires additional row of physical pins.
SDXC host devices accept all previous families of SD memory cards.
Speed CLASS rating:
Class 2 2 MB/s
Class 4 4 MB/s
Class 6 6 MB/s
Class 10 10 MB/s
UHS Speed Class 1 (U1) 10 MB/s
UHS Speed Class 3 (U3) 30 MB/s
Very Big Thanks To Flipkart.com
Very Super Product...
in this product write speed is 4 to 5 MB/s..
Yes It is + ..
Its All Abouut FlipkArt..
N about Transcend 8GB Class 4 Micro Sd ..
1st of all D Price is very less As compare to othr brands 8gb cards, Data sending n write Speed is so fast more than 4mbps.
may I Suggest to u . all If u r using a Smartphone den Definitely buy dis 8gb cards its Awesome...
It was not original product, Last time I bought transced class 4 memory card from CTC hyd, its speed working with good speed but this memory card speed is too low it is approx 20 Kb/sec. It was not genuine products.
Transcend is best Company in Storage Chip Making.it's better then other companies I used transcend 1Gb SDHC first time when i got a multimedia phone in 2007 and it was still working.The speed of data transfers remain same from the time i got it.I have also a Transcend flash drive which is awesome!!!!
Bad Part: If you are trying to copy a bunch of songs or videos from your system to the card you will have to wait ages to get it done. The writing speed is less that Mbps and reading speed is about 1-Mbps.
Good part: You will get your order delivered with in two days, and if you need a enough memory space in a very less cost you can go for this. Nothing beats this in the cost range.
