The ability to download content for offline viewing was introduced by Netflix in November last year. Android and iOS device owners could opt to download content on to their smartphone or tablet for viewing later on, and when an Internet connection is not guaranteed to be available.
For Android users, the download experience just got a little better. Netflix updated its Android app and added SD Card support. Within the app you'll now find a "Download Location" option which allows you to "control where to save downloaded content." The two options being internal storage or SD Card.
For those of you with very limited internal storage on your device, but have a Micro SD card slot, this likely opens up Netflix downloads as an option. Just invest in a decent sized Micro SD card (e.g. a 32GB card costs around $10) and get downloading. All the Netflix app requires is a new permission to allow access to the card.
While this should allow more content to be downloaded at any one time, there are still restrictions. Engadget spoke with a Netflix rep who explained that content can be downloaded to multiple SD cards, but playback can only occur on the device downloading the content. Downloads only remain playable for a limited time, and there's also limits on how much you can download.
Specific limitations weren't given by the rep and also aren't listed in the Netflix Terms of Service (Section 4.5). If you have a big enough SD card you can always try and find out what those limits are.
