SD Card

Secure Digital (SD) is a flash (non-volatile) memory card format developed by Matsushita, SanDisk and Toshiba for use in portable devices, including digital cameras, handheld computers, PDAs and GPS units. As of 2007, SD card capacities range from 8 MB to 16 GB. Several companies have announced SD cards with 32 GB.

Cards with 4-32 GB are considered high-capacity. The format has proven to be very popular. However, compatibility issues between older devices and the newer 4 GB and larger cards and the SDHC format have caused considerable confusion for consumers.
SD cards are based on the older MultiMediaCard (MMC) format, but have a number of differences: ?The SD card is asymmetrically shaped in order not to be inserted upside down, while an MMC would go in most of the way but not make contact if inverted. SD cards typically have higher data transfer rates, but this is always changing, particularly in light of recent improvements to the MMC standard. Devices with SD slots can use the thinner MMCs, but the standard SD cards will not fit into the thinner MMC slots. SD cards can be used in CompactFlash or PC card slots with an adapter. miniSD and microSD cards can be used directly in SD slots with a physical interface adapter.There are some SD cards with a USB connector for dual-purpose use, and there are card readers which allow SD cards to be accessed via many connectivity ports such as USB, FireWire, and the parallel printer port. SD cards can also be accessed via a floppy disk drive with a FlashPath adapter.

Universal Serial Bus USB Drives Portable Data Storage For Your PC

Universal Serial Bus or USB Drives are compact and generally are connected to the USB port to transfer data between PC and USB Drive. If your PC does not have a USB port then you can use a USB connector to connect the drive.  USB Drives are also known as; pen drives, flash drives, or thumb drives.  USB Drives have been used as an alternative to floppy disk drives. Comparatively it is smaller, faster, removable, and more user friendly than a floppy drive. And the capacity of this drive is many times more. It supports USB-2 which is more faster than any other USB. It supports  about all operating systems(Windows, Linus UNIX, MAC, etc).

Some key features to consider when you buy:

1. Capacity: How much capacity do you need?

2. Shape, Size and Color: Since its works as pocket/pen drive too, so size and shape, color, and design can be important factors to users.

3.  Automatic Install: Choose the drive which will install automatically. If not, manual install may be boring to you. Here you should see the security features too.

4. Budget: Budget is also a significant factor when buying something.

5. Warranty: See the warranty start date. It may start from the production date! Yes, tell retailer to clarify the warranty period if necessary.

SSD Solid State Disk Drive has no moving parts

A Solid State Disk Drive (SSD), some times called a solid-state disk drive or electronic disk is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner as a traditional block i/o hard disk drive. SSDs are different from traditional magnetic disks such as hard disk drives (HDDs) or floppy disk drives which are electro-mechanical devices containing spinning disks and movable read/write heads. In contrast, SSDs use microchips which retain data in non-volatile memory chips and contain no moving parts. Compared to electro-mechanical HDDs, SSDs are typically less susceptible to physical shock, are silent, have lower (i.e. faster) access time and latency but are more expensive per gigabyte (GB). SSDs use the same interface as hard disk drives, thus easily replacing them in some applications that require faster speed and smaller size.

As of 2010, most SSDs use NAND-based flash memory, which retains memory even without power. SSDs using volatile random-access memory (RAM) also exist for situations which require even faster access, but do not necessarily need data persistence after power loss, or use external power or batteries to maintain the data after power is removed.

A hybrid drive combines the features of an HDD and an SSD into one unit, containing a large HDD, with a smaller SSD cache to improve performance of frequently accessed files. These can offer near-SSD performance in most applications (such as system startup and loading applications) at a lower price than an SSD. These are not suitable for data-intensive work, nor do they offer the other advantages of SSDs.

MicroSD is a super-compact memory card the size of a fingertip

MicroSD is the format for flash memory cards that can be in used in pairs and removed easily from mobile phones or other digital devices that use this memory format. And the meaning of SD is Secure Digital. Alot of MicroSD memory cards have been sold in the market, with Micro SD memory capacity up to 64 GB (Gigabytes).

MicroSD is a super-compact memory card with the smallest size of 11 mm x 145 mm x 1 mm, almost the size of a fingertip. Very compatible and comfortable to use on mobile devices and mobile phones. Formerly this product was called T-Flash, then changed its name to TransFlash after it was officially renamed to MicroSD and endorsed by the SD Association.

What is Blu-Ray? not Blue-Ray

Blu-ray Disk (BD) is a new optical disc format with high storage capacity. It was developed by Blu-ray Disc Association (BDA) and world's leading consumer electronics, personal computer and media manufacturers. A single layer disk has a capacity of 25GB, about five times of a DVD and a dual layer has a capacity of 50GB.

Most of the High Definition Videos are written on blue-ray disks giving an extraordinary HD experience for the consumers. DVD, DVD±R, DVD±RW, and DVD-RAM are based on a red laser to read and write data but Blu-ray uses a blue-violet laser instead. Blu-ray is currently supported by most of the world's leading consumer electronics, personal computer, recording media, video game and music companies.
