Frequently asked questions

How is a flash drive used?

Insert your flash drive in the USB port of your PC or device with a USB port. The device drive will appear automatically, but if it does not, click “Start”, open the “My Computer” folder and look for the new drive. Drag the files that you want to save to the folder displayed on your screen.

Before removing the flash drive from the USB port, make sure you notify the operating system: “remove hardware safely” from “Device manager” in Windows.

If you remove the flash drive too soon, the files might not be transfered properly. You might even damage the flash drive because electricity flows through the USB and removing it too soon could damage the chip. You should also keep the flash drive away from humidity, magnetic fields and extreme heat.

What are the advantages of using a USB flash drive instead of external hard drives?

The biggest advantage is the size. USB flash drives are smaller and easier to carry. What's more, they do not have to be set up and are very sturdy. Hard disks use needles, while USB flash drives use solid memory, which is why they are far sturdier.

What are the advantages of using a USB flash drive instead of a CD-r or DVD-r?

Nowadays all computers come with a USB port, but very few people have a CD or DVD burner. Besides, downloading from a PC to a USB flash drive is far easier and faster than copying a CD or DVD.

With USB flash drives, you can store and delete data as many times as you want. To get the same performance from a re-recordable DVD or CD, you have to look after it very carefully.

Are all USB flash drives the same?

Sometimes errors occur during the production process, leading to faulty storage cells inside the USB flash drive chip. These blocks cannot be used to store information, which is why the actual capacity of a 1GB flash drive might be reduced by 512MB.

Some manufacturers mark these flash drives with faulty cells as “downgrade” and sell them at cheaper prices.

Problems with downgrade flash drives:

  • Errors when saving information (too many faulty cells).
  • Rated nominal speed data rate.

Will my USB flash drive run in any computer?

Our USB flash drives are compatible with Windows 98SE/ME/2000/XP/Vista, from Linux 2.4.X and MacOS 9.X. For Windows 98 (1st edition), you will need to install the appropriate drivers, which you can download at this link or else ask for the CD driver accessory.

Why do some flash drives not allow software and permanent data insertion?

Whether or not permanent data can be inserted in the flash drive depends on the controller, which is the intelligent component of the device and decides in which part of the NAND flash drive the data are saved.

Go to start

What's the difference between permanent data insertion and MyData?

The space of the flash drive is divided into two parts: one is used to permanently store the data that the customer wants to distribute (A) and the other to store the information that the end user wants to save (B).

In the case of the permanent data insertion service, the data provided by the customer are always kept in the permanent part of the memory (A) and the end user will never be able to delete them, even temporarily.

With the MyData service, whenever the USB flash drive is inserted, the data provided by the customer are automatically copied from one part of the memory to the other. If users try to delete the data, they can do so, but the next time they insert the flash drive, the data will be copied again from one part of the memory to the other and it will appear again. How long this automatic copying process lasts will depend on the size of the file or files. To ensure the data is copied fast, we recommend that the file is never bigger than 30 MB.

Go to start

What advantages does the MyData service offer with respect to permanent data insertion?

With the MyData service, the information that the customer wants saved in the memory is far more visible to users, because the data that is stored permanently in the device is copied in the area that the end user will use.

Go to start

What advantage does the permanent data insertion service offer with respect to MyData?

This service is less intrusive for users because the data is stored in the part of the memory that they use the least, and they will only see the files if they access this part. The USB device is available faster than in the MyData service, because in this case the data is not copied automatically.

Besides, the limit on the size of the data inserted by the customer only depends on the capacity of the memory chosen.

Questions about the components of our USB flash drives

What's a NAND FLASH memory chip?

The NAND flash memory chip represents 80% of the cost of the USB flash drive and is used to store data. It contains an array of cells where the information is stored. They can store one or two bits of data per cell.

Go to start

What is SLC?

SLC stands for Single Level Cells

SLC flash memory is a high-performance NAND Flash memory chip. Its use is related to high-performance and long-durability applications. It is used for Compact Flash cards, professional cameras and USB flash drives for advanced or professional IT users, among others. The device in which it is used must be compatible with USB 2.0 to ensure the best performance.

This type of flash memory stores one bit per cell, enabling faster read and write speeds; it also boosts the lifetime of the memory to 100,000 write cycles per physical sector.

Speed of the Devices fitted with SLC memory have write speeds of 40 Mbps and read speeds of 240 Mbps.

Go to start

What is MLC?

MLC stands for Multi Level Cells

MLC is a high-performance NAND Flash flash memory chip that stores two bits per cell, and the data are encrypted before being saved. Endurance is up to 10,000 write cycles per physical sector. MLC flash memory is approximately three times slower than an SLC, which is why it costs less.

It is used for devices such as USB flash drives, memory cards for mobile phones, PDAs and cameras.

The performance offered by MLC memory chip is sufficient for the average user. According to research conducted by Toshiba, its 10,000 write cycles would allow consumers 'to write completely and erase the memory's full contents once a day for 27 years'.

All these reasons are why MLC flash memory chips are used most in all kinds of electronic devices with NAND Flash memory chips.

Devices that are fitted with MLC flash memory chip have a write speed of 15 Mbps and a read speed of 48 Mbps.

What is USB 2.0?

A Universal Serial Bus is a port that is used to connect peripherals to a computer.

USB devices are classified in three types depending on their throughput:

    Low rate (1.0): Bitrate of 1.5Mbit/s (192KB/s). Mainly used by “Human Interface Devices” (HID). Present in keyboards, mice and joysticks.Full rate (1.1): Bitrate of 12Mbit/s (1.5MB/s). Many devices manufactured at present work at this rate. These devices divide the bandwidth of the USB connection between them, based on a FIFO algorithm.High rate (2.0): Bitrate of 12Mbit/s (1.5MB/s). The used one most.

What is the PANTONE code?

Pantone Inc. is a corporation headquartered in New Jersey (USA), and which invented a colour control system for the graphic arts industry. Its system is the best known and most widely used, which is why the colour control system is normally called PANTONE.

The system is based on a range of colours, the Pantone Guides, that is used to obtain others by mixtures of predetermined tints. The advantage of this system is that each of the samples is numbered and once selected, the exact colour can be reproduced.
