USB 2.0 flash drives look the same, but that does not mean they perform the same medium.

different types of memory, and to a lesser extent, I type / use the drive through the USB device can make 2 or 3 times faster and last (theoretically, O controller at least) 10 times the other, even if the two a movement of the USB 2.0 logo. apad

Unfortunately, there is no generally accepted industry standards or certification for ordinary users to determine which wedding dress,

the temporary user may not notice. Expensive drive with more than one drive, or even enough to drive the last a normal life in the life of expensive short-term users.

However, these differences can be whatever you store large amounts of data, use the drive to store critical information, or use the USB drive to supplement system memory using Windows Vista’s ReadyBoost feature.

key performance factors memory cards

the USB 2.0 standard supports a maximum throughput of 60MB/sec. Although business in.

USB drive in the performance of the most important factor is whether it contains two types of memory: SLC (single-level cell 1) or MLC (multilevel cell). SLC memory 1, and MLC stores two bits of data in each memory cell. SLC twice the speed of the Congolese Liberation Movement, he said, is gradually increased, about 14 MB / sec, the highest reading. And the 10-12MB/sec write speed. Not surprisingly, almost all USB flash memory drives with MLC, SLC, more than double the cost of the MLC.

SLC and MLC users will see the performance difference between the maximum,dvi to hdmi converter, if they show a lot of business involved a small file, rather than the relatively small number of read / write large files, John Whaley said, In MokaFive company, its main virtualization software engineers, so that the virtual machine is stored on USB flash drive.

SLC memory also lasts about 10 times as long as the Congolese Liberation Movement, Crandall said, which means 1 SLC – in the USB drive should be based on past data write and erase cycles before the cell, 100 000 failed. However, this difference is not concerned about the number of users.

began when the USB drive fails, they do a one cell, not across the board, Crandall said. That is why the SLC-based drives may be a store user,lcd portable dvd player, for example, in a flash drive, the virtual machine disaster recovery to its value, according to Wilkison. If the drive began to fail, drop bits may not be in the photo or music track, but you can see a system crash, if their operating system from the disappearance of an important part.

And I / O controller

One is to use multiple channels, while mobile and data from memory, said Brad Anderson, product marketing USB flash drive suppliers Lexar Media Inc. In addition, he said, is intertwined with the director in which the data flow and Mixing a variety of flash drives from within, in order to ensure maximum potential applications of the memory chips.

Like many other design details

and would be difficult to determine which I / O controller is used for a particular drive, and provide any functionality. While consumers can try to find out I / O controller is a particular drive use, and to explore how to control the project, most buyers will be under Wilkison, to in its controller. TF card

No standard

 

now, perhaps the only way to know if you buy a drive, use SLC memory is how much the cost – more expensive drive, the more likely it is to use the SLC that has been built. bar cell phone

there a way to judge quality in addition to higher prices: in Windows ReadyBoost logo, which shows that flash drives can be used to supplement the system memory, thereby speeding up the performance of the computer Windows Vista.

But only 2.5MB/sec for Windows ReadyBoost minimum specifications. Random Read 4KB of data,cheap phone mobile, and 1.75MB/sec. Random data, Crandall said, 512KB write low-cost and low-speed USB flash drive typical. Customer who wants to benefit from the Windows ReadyBoost The device should be possible to choose the best, the average price of its high-end high performance and a USB drive sales.

the future

For reading and 30MB/sec. For writes, getting closer and closer – but not quite – saturated with USB 2.0 interfaces. firewire cable

for their speed and reasonable price than any other USB drive, the importance of reliability should do the average consumer price. However, if the speed or longer life is critical, high-performance drive in the ad, do your research, is expected to spend more online. But even so,rca to ipod, you can not be absolutely sure you want your money, more speed.
