An Uninterruptible Power Supply (UPS) is an electrical apparatus that provides emergency power to a load when the input power source, typically mains power, fails.
A UPS is vital for people who need to feel maximum confidence their data is safe at all times, especially in the event of a power loss or failure.
Almost all Angelbird Solid State Drives (SSDs) are fitted with a UPS as standard, including the internal SSDs and all of the external SSD storage solution SSD2go.
Surprisingly, most SSDs on the market do not feature an Uninterruptible Power Supply (UPS), in fact Angelbird is the only commercial SSD on the market that features UPS as standard; otherwise this feature is only found in high-end enterprise level SSDs.
A UPS is a very important feature for those who take looking after their data at all times seriously. Professional users, such as media professionals or programmers who don’t want to ever risk losing data will always want to use SSDs with UPS.
While data is generally considered safer with an SSD than a conventional Hard Drive, in the event of a power failure there is a one in four-hundred chance that the firmware dies which means the SSD is dead. With a UPS fitted in the SSD, as are in almost all Angelbird SSDs, the chances of this happening are greatly reduced. This is because the UPS means there is a little battery inside the SSD that enables a four seconds power loss protection (UPS) which, in case of power loss, will perform a flush command and after flushing will shut down the controller and the whole device safely.
Even if the whole SSD is not dead, if you are working with video or audio files, there is a very high chance of data corruption in the event of a power loss. When using Angelbird SSDs, you know your data is extremely safe because they have the UPS feature built in. That’s why more and more professional and home users are choosing Angelbird SSDs.
As well as its own UPS, Angelbird SSDs are the only non-Apple SSDs on the market that come out of the box TRIM enabled. This is a command used in the operating system to wipe invalid data blocks on solid-state drives (SSD) which are no longer in use - including data blocks which have been left by deleted files.

The UPS and TRIM features are also included in the Angelbird SSD2go mobile storage devices, plus the device has a highly accurate temperature sensor built in.
The shell of the SSD2go is made from top grade aluminium. This allows the product to be very stable with the high thermal dissipation to get real world operation temperatures of only 32 - 40C which results in very long life and stable performance.
SSD2go is anodised in various colours which allow up to 64 colour combinations. This way the SSD2go is not only the best portable SSD on the market, it gives the user the ability to fit it into his or her own individualised computer setup.
Angelbird use a Sandforce controller for our SSD2go because the cache is built into the controller and very small. This ensures that in the worst case scenario the UPS can handle the proper writing of the cached bits and will prevent data loss. Had we used a cache based controller with 256 or 512MB, the risk of losing data in certain cases would have been too high.
The difference in cached and non-cached controller based SSD products will be visible in benchmark results. Cached solutions will show better stability since the benchmark tools will mainly test the cache and not what’s happening behind that.
Un-cached solutions show more unstable results since benchmark tools will display what’s really happening with the device.
The SSD2go is the only product which supports SMART on Mac. SMART is a feature that lets your computer know when the drive is failing, allowing you to plan ahead for a replacement.
