Samsung SmartMedia 128MB Smart Media Digital Flash Memory Storage Card
This Samsung SmartMedia card is a removable flash memory card that can be used in several different types of digital devices, including digital cameras, digital music players and digital voice recorders. Advanced features include: high transfer rate for fast copy/download, multiple storage capacity, unfazed by drastic weather conditions ranging from blistering heat to freezing cold.
the
smartmedia cards are extremely easy to use with a variety of portable
devices. With a range of capacities from 16mb and 32mb to 128mb, smc
smartmedia cards are the perfect solution to upgrade the memory for
your portable digital device.. It can also be used in equipment that
requires a removable memory chip for portability, version upgrades or
memory upgrades for applications. Its dimensions are 45.0 x 37.0 x
0.76mm and it weighs only 2g.
A single 128MB SmartMedia card can hold up to 800 photos or nearly 20 minutes of video.

DDR memory
DDR memory
( Double Data Rate memory), is a new high performance type of memory
that runs at twice the speed of normal SDRAM. This DDR SDRAM is ideally
suited to the latest high performance processors to increase overall
system speed. The faster the memory, the quicker DDR Memory PC 3200, PC2700 and PC2100
, PC2100 SO-DIMM - 184 pin, 200 pin instructions can be passed to the
processor. DDR memory provides roughly a 15% boost in performance
compared to regular SDRAM. With DDR memory now in the affordable price
range, and motherboard manufacturers phasing out SDRAM on nearly every
new board, it looks like DDR is definitely here to stay
It must be remembered that if you want to upgrade the memory of a computer that uses DDR1, you cannot buy a DDR2 module and use it to supplement a DDR1 chipset. The slots for DDR1, 2 and 3 are different. Some motherboards, however, have slots for all these DDR formats. The booklet on the motherboard should tell you how to install additional RAM on your computer. Sixty-four bit processors often support more than 3.5 GB of DDR RAM. A 64-bit Windows Vista system, for example, will support memory of up to 128GB.
A DDR RAM operates
at a lower voltage than an SDR RAM, resulting in lower power
consumption. Though it has the same architecture as an SDR RAM, a DDR
RAM has 184 pins, instead of 168. It also has a single notch at the
connector, not two. The bus width of DDR memory is 64 bits per channel.
Most DDR-based chipsets come with matched pairs of modules and are made
for processors that are 1GHz or faster.
DDR memory
is the latest in high-performance memory module technological advances.
It offers twice the data bandwidth of conventional PC100 or PC133
SDRAM, and is particularly well suited for high-performance servers and
workstations, which need optimal CPU-memory performance.
Memory Card Speed Explained
Memory Card Speed:
Memory card speed is the card's performance with regard to how quickly data can be transferred to or from it. compare cards by the “X” speed, such as 80X, 150X,The card speed is often stated in -Times- ratings i.e. 12X, 40X etc (just as the speed of recordable CD's and DVD's is measured), and sometimes more specifically in megabytes per second (Mb/s).X is the baseline equal to a card accepting 150KB in one second. By today's measure, sub 20X represents a standard speed, 20X to 40X is mid-high speed and over 40X is high speed. The chart below shows the relationship between the two figures.
- 1X = 150KB per second
- 8X = 1.2 Mb/sec
- 10X = 1.5MB per second
- 12X = 1.8 Mb/sec
- 20X = 3.0 Mb/sec
- 25X = 3.8 Mb/sec
- 30X = 4.5 Mb/sec
- 40X = 6.0 Mb/sec
- 50X = 7.5MB per second
- 60X = 9.0 Mb/sec
- 66X = 10.0 Mb/sec
- 80X = 12.0 Mb/sec
- 90X = 15.0 Mb/sec
- 133X = 20.0 Mb/sec
- 150X = 22.5MB per second
- 300X = 45MB per second
Faster cards can accept more megabytes of information per second. But just how much of an advantage is a faster card? With some cameras, there isn’t much advantage to using a faster card, while others will benefit from the high speed.
The Secure Digital Association (SDA) defines three speed classes in order to let users identify speed and performance capabilities of SDHC cards and the host products. The speed class rating specifies a MINIMUM sustained write speed for SDHC cards.
- Class 2 = 2MB per second
- Class 4 = 4MB per second
- Class 6 = 6MB per second
