Choosing Your USB Memory Stick Supplier

Choosing Your USB Memory Stick Supplier
by Chris Proth

There are currently many suppliers of Branded and Promotional USB Memory Sticks. This makes it a fiercely competitive market, which bodes well for the consumer as this naturally leads to lower prices. However, this also puts a lot of pressure on suppliers to reduce their costs. Some suppliers take this too far so it is important to consider factors other than price when choosing your USB Memory Stick supplier, four important considerations to take into account are:

1. Speed of Service 2. Quality of USB Memory Sticks 3. Financial Stability of Company Supplying Flash Drives 4. Reputation.

Speed of service will largely depend on the company's business model. Many companies claim to have fast turnaround times, but when asked to supply large amounts of branded USB Memory Sticks they fall short on initial promises and the turnaround times go up 2 or 3 times. Other companies who have more control over their supply chain will live up to their promises and these are naturally the companies you'll want to choose.

Quality control is crucial for products that will end up representing your company. It is important to find a supplier that understands this and won't cut corners or send you defunct goods. For instance, some USB Flash Drive suppliers cut costs by using refurbished NAND flash memory. This is generally less reliable than brand new NAND Flash. It may save you money, but do you want the product you've given to a client failing? This is not going leave your company in a good light, and once they've thrown the USB Stick away they're no longer carrying your companies name around with them.

As with any company you're going to enter into a financial relationship with it's always prudent to run a credit check to make sure it's not going to go under in the next month or so, if it does you're unlikely to get your money back. As mentioned earlier, this is a very competitive industry and insolvency is not that uncommon, if your supplier goes bankrupt you wont only lose the money you paid them you'll also miss your deadline.Reputation speaks volumes, if a company has delivered similar sized orders of USB Memory Sticks in the time frame you want many times before, they can probably do it again.

microSD card also known as Transflash

microSD card also known as Transflash
by Shawn paul

Micro-SD card is also written as SD. TranshFlash was formerly known as T-Flash. The micro SD memory card was introduced by SanDisk Corporation in 2004. This was known as the world's smallest memory card. Its size is 15mm × 11mm × 0.7mm which is approximately that of a fingernail. The transflash was specifically designed for being used in mobile phones. Motorola was the first mobile phone manufacturer to adapt the TransFlash memory card standard. It is about a quarter the size of an SD card. There are adapters which allow a microSD card to be used in devices intended for SD, miniSD, or MemoryStick Duo cards, however they are not universally compatible.

In the mid of 2005, transflash was adapted by the SD Card Association as the third form factor memory card in the Secure Digital family, after SD Memory Card and mini-SD. TransFlash name was changed to microSD, after its adoption by SD Card Association. TransFlash and micro-SD, both memory cards are completely compatible to each other, because they have exactly the same dimensions and specifications. Nowadays, microSD is the most common used memory card in mobile phones. It is the objective of SD Card Association to make microSD a de facto memory card standard for all mobile phones. All the microSD cards and TransFlash come with a SD Memory Card adaptor, which makes them compatible to all SD Memory Card slots. The microSD is about 10% in size compared to SD memory card and about 30% compared to miniSD. Following are given the technical details of the µSD cards. Micro SD-card Card volume 165 mm3 Weight Approx. 0.5 g Operating Voltage 2.7 - 3.6 V Number of Pins 8 Write-protect Switch No Terminal Guards No Width X length X thickness 11mm X 15mm X 1mm

ScanDisk-An Overall Look

ScanDisk-An Overall Look
By [http://ezinearticles.com/?expert=Mike_Singh]Mike Singh

The leader in flash memory, ScanDisk delivers more flash memory products than anyone else in more form factors. They carry 315 issued U.S. patents along with 160 foreign patents, so it is very clear to see that ScanDisk is THE inventor of flash data storage. ScanDisk was founded in 1988 by Dr. Eli Harari, who was an internationally recognized authority on non-volatile memory technology. They serve both consumers and original equipment manufacturer, while licensing its technology to a number of other industry-leading companies.

Flash memory is a rapidly growing field, due to the direct result of "consumer demand" for always something smaller, more feature packed, more portable, and always wanting a digital device. Because of this reputation, available is a great, diverse line of MP3 players to suit every consumer with MP3 desires. SanDisk is a name to consider when shopping for your digital audio player as it provides a line of digital audio players with video capabilities, FM tuners, expandable memory, and voice recording. With five different lines of digital audio players to choose from it is probable to find something that fits a specific taste.

The SanDisk "SansaTM" e200 series of MP3 players give the consumer the capability of music, photo, and video clip playback - all in one device. With a 1.8" TFT color screen and advanced navigation, along with a very easy to use interface, this line comes with three choices of disk space - 2GB, 4GB, 6GB, and 8GB, with a strong battery life at about 20 hours when fully charged. It has a durable metal backing to avoid excessive scratching, which is an advantage over others. Supporting the Microsoft PlaysForSure subscription music, a media converter can be purchased to support most image formats for photos and small personal videos.

SanDisk's SansaTM m200 series provides high-quality digital music playback as a replacement to the original Digital Audio Player line, as SanDisk is one of the leaders in the flash drive arena. This series doesn't offer anything flashy (no photo or video), but does everything you need if you are looking for pure digital audio. The series comes in the 512MB (blue), 1GB (silver), or 2GB (black) sizes with optional data storage capabilities. It also can be used as an external storage device for data and a PC transfer case.

The SanDisk SansaTM c100 series is made for the active type, by providing flash memory of 1 or 2GB in a lightweight and durable device that is available in brilliant color. You can listen to music downloaded from the PC, listen to FM radio, record FM radio, or make voice recordings while jogging or studying. The SanDisk Sansa c100 series can also display photo thumbnails, but has no video playback capability. If a person is new to the digital audio game, not quite knowing how much space they need, the SanDisk SansaTM e100 series of expandable memory MP3 players is a great option. Coming with a built-in 512MB or 1GB of memory, a person can expand the space by up to 2GB with a SD slot memory card. This player also comes with a built-in FM tuner.

Mini SD-cards

Mini SD-cards
by Shawn paul

The multi-media-card (MMC) was developed by Siemens AG and Sandisk in 1997, which was the smallest memory card. The MMC had size of 32 × 24 × 1.5 mm. Its size was about that of a postage stamp. The MMC-card and SD card (Secure Digital Memory Card) are very much similar. The Secure Digital Memory Card is based on the MMC-card. Both of them have almost the same form factor, but the SD cards are slightly thicker and they have a write protection switch. The SD (Secure Digital) is a non-volatile, flash memory card format. SD-card was developed by SanDisk, Toshiba and Matsushita. SD cards are mostly used in handheld computers, digital cameras, GPS receivers, PDAs, video game consoles and mobile phones. There was need to develop a memory card that was small enough to meet the requirements of compact mobile phones. Therefore, the miniSD card was introduced by SanDisk Corporation in 2003. The mini SD-card also includes copyright protection. In order to make the mini-SD card compatible with standard SD-enabled products, the mini SDcard comes with an adapter. These memory cards are slim and compact. They are ideal for MPEG2 Video Recording. Mini SD cards have large capacity and fast access. The copyright protection technology used is the key for enabling a new distribution system for music and other commercial media.

The miniSD Card is a small form factor removable and portable memory device. It is used in digital cameras, MP3 players, mobile phones / cell phones, and many other gadgets. The SD Association in 2003, adopted mini-SD as an ultra small form extension to the SD card standard. The memory cards usually have miniSD adapter for the use in mobile phones. This adapter enables compatibility with all devices equipped with a standard SD Memory Card slot. The compatibility of the miniSD cards is universal regardless of its manufacturer. There is another form of SD-card which is called as microSD. The microSD card may be used in miniSD devices by using an adapter. On the other hand, miniSD cards can not be used in microSD devices.

Following are given the technical details of the SD card, mini SD-card and microSD cards. SD Memory Card Card volume 1,596 mm3 Weight Approx. 2 g Operating Voltage 2.7 - 3.6 V Number of Pins 9 Write-protect Switch Yes Terminal Guards Yes Width X length X thickness 24mm X 32mm X 2.1mm miniSD card Card volume 589 mm3 Weight Approx. 1 g Operating Voltage 2.7 - 3.6 V Number of Pins 11 Write-protect Switch No Terminal Guards No Width X length X thickness 20mm X 21.5mm X 1.4mm Micro SD-card Card volume 165 mm3 Weight Approx. 0.5 g Operating Voltage 2.7 - 3.6 V Number of Pins 8 Write-protect Switch No Terminal Guards No Width X length X thickness 11mm X 15mm X 1mm
