Reliable Edge Storage in a Connected World
Traditionally, TV viewing features such as pause live TV and catch-up TV require
a hard drive (HDD) within the set-top-box to enable the recording, storing and
playback. To do so, a video buffer is created by constant recording and re-recording
to the set-top-box to allow consumers to pause, rewind, play and fast-forward live
programming.
Today, subscribers to live and streaming video services expect to access their
content on-demand — anytime and anywhere. To meet that expectation, MSOs
are transitioning to a cloud DVR architecture (cDVR) that allows the content to be
stored in the cloud. This facilitates the whenever, wherever access of programming.
This, however, dramatically increases bandwidth demand. Therefore, the hybrid
model, with some local storage in the set-top-box combined with cloud storage,
allows the MSO to balance the growing pressure in bandwidth and to reduce the
investment for TCO and infrastructure. These benefits have seen this hybrid solution
adopted rapidly over the last few years.
Other devices for connected home — such as set-top-box (STB), over the top
(OTT), home gateway, smart TV, and smart security camera – are also designed to
have content continuously recorded to the storage. As these devices are getting
smaller and slicker by design and more versatile by functions, so are the require-
ments for their functionality, performance and reliability.

related with the amount
of time the data will stay
valid (data retention) and the write performance of the memory module. Therefore,
it is important to customer satisfaction as well as the bottom line for MSOs
to decide on the right NAND Flash for product implementation.
The SanDisk High Endurance product line for connected home is specifically
designed to optimize performance for applications that require constant and
continuous writes to the card. They are built to meet the MSO’s special reliability,
endurance, and quality requirements and provide additional tailored features that
will help reduce the total cost of ownership by enabling remote support and
maintenance by MSOs.
