One of the many innovations keeping our SSDs ahead of the pack is the deployment of our Guardian TechnologyPlatform. With our recent advancements in SSD controller technology leading up to the development of the Guardian TechnologyPlatform, we have been able to design storage devices that yield better performance, reliability, endurance, and affordability necessary for today’s enterprise applications.
Offering these benefits at a lower cost is possible through the powerful flash management techniques which make up the Guardian TechnologyPlatform. By combining cost-effective MLC flash with extended endurance, we are able to offer an SSD that can meet the demanding requirements of enterprise applications. Three prominent components combine to make the Guardian TechnologyPlatform: FlashGuard, EverGuard, and DataGuard. Here’s a quick snapshot of each technology:
FlashGuard is the core of the Guardian Technology Platform, as it was developed to extract higher endurance from MLC flash. This cutting-edge technology is possible through two technological breakthroughs – Aggregated Flash Management and Advanced Signal Processing, which we will talk about more in-depth in a future post. With these two technologies comprising FlashGuard, we can now offer enterprise class MLC‐based SSDs with a 5‐year warranty at usage rates of up to 25 full drive writes per day.
DataGuard provides superior data integrity by protecting user data from corruption at all points in the drive and from loss in the event of page or block failures in the flash. DataGuard also includes a cross‐die data redundancy feature called F.R.A.M.E. (Flexible Redundant Array of Memory Elements) which is the enabling feature responsible for the recovery of user data in the event of catastrophic events, such as flash page or block failures.
EverGuard prevents the loss of data in the event of unexpected power interruptions. This technology includes an array of high reliability solid‐state capacitors that act as an independent power supply for the drive during power interruptions. It also ensures all user data is transferred from the write cache to the flash.
With the Guardian Technology Platform, our SSDs represent a new generation of affordable enterprise storage solutions optimized to meet the needs of the ever‐increasing performance of mainstream enterprise applications.
