Depending on type (SLC, MLC) flash storage cells can be written or deleted differing often. When the number of write/erase cycles, specified by manufacturer, is nearly reached or the limit is exceeded reliable data storage is no longer available. As opposed to long-lasting SLC flash cells with up to 100.000 write/erase cycles in the meantime 3 bit saving MLC flash (TLC) is available on the market - for small structural sizes of chip die just specified for 1.000 write/erase cycles.
The problem
Nowadays there‘s a great many of flash data media of particular relevance developers and purchasing agents have to integrate into their selection process for the choice of a suitable flash memory medium. The right coordination of flash type, capacity and planned service life of used flash memory in applications is also a particular difficulty. The manufacturer‘s information for service life often are no lifesaver as the basis for this information are normed write/erase cycles, a wide difference to practical operation. Just a vague point of reference for a flash memory preselection during the phase of evaluation.
The solution
For the first time the „altec SSD Life Test Tool“ enables a proper evaluation close to the application of selected media with real parameters of write/erase scenario from your application.
With the „altec SSD Life Test Tool“ you will find the perfect medium for your application easily. This tool not only helps you to reduce costs in purchasing, the reliability of your appliÂcations will increase and minimize costs caused by unexpecÂted malfunctions of flash memory.
Precise profile creation
First the „altec SSD Life Test Tool“ user defines the service life for the evaluation medium. Then the „altec SSD Life Test Tool“ writes free configurable access patterns (data transfer profiles) onto the evaluation medium until the proper service life is determined.
Create the required data transfer profiles in tabular form or more precise determine it by means of direct logging. For precise logging altec offers the special developed „USB L.T.T. Traffic Flash Drive“. Instead of the actual flash memory medium the „USB L.T.T. Traffic Flash Drive“ is used in the application during the logging period, saving the data transfer profile.
Afterwards the profile from the „altec SSD Life Test Tool“ is read in and the detected access pattern will be written onto the flash memory medium for evaluation. Even for closed systems or systems with dynamic data transfers it is often the only way to get a meaningful data transfer profile.
