New Flash Disk Card.
There are more and more storage devices based on flash memory technology appearing every day. Following the trend, Mistral Solutions Pvt. Ltd. has released a flash disk card. It can be used as a replacement for convenient hard disks. The company itself positions it for extreme environments where standard disks are too unreliable. The flash disk card can support JBOD and RAID via software. The card comes in size of 8/16/24/32/64 GBytes.
Cards like these and flash based hard disks are great solutions, unfortunately too expensive for end users these days. Still, as Windows Vista promotes the concept of flash based storage in PCs, it is expected that prices of flash drives will go down and they would be more affordable to be deployed in computers and servers.

Well, there is a number of companies offering hard disks based on flash memory. These can be easily googled.
The advantage of flash memeory disks and cards lies in the performance. These cards and disks easily outperform the fastest conventional disks on the market by the factor of 20 or more. Average disk access time and seek time are extremely small. The drawback is that this type of storage is extremely expensive.
So it is great to use this type of storage for any type of server applications, video encoding and any applications that operate large number of small files. This performance comes at a price of a decent car for every disk in the system.

Can any body tell me about the life time expected for a flash drive?? How does it compare to a regular drive?
Is there a limit to the number of read/writes before the flash drive stops functioning ???

It has longer life expectancy and can withstand higher physical shocks. These disks differ from standard compact flash memory which have a limitation on number of read/writes. There are also systes which are based on standard memory (like DDR, DDR2, SDRAM) and require constant power supply. In case there is a powercut such systems won’t be able to hold data for long as their internal batteries can provide power only for a limited period.
