The WD Purple series is designed to withstand more rewrites and at wider temperature ranges than a consumer-grade variant. Applications where constant data access is vital, such as on surveillance systems or servers, can benefit from the increased reliability of the WD Purple MicroSD card. Prices start at just $18 USD for the 32 GB version with a 64 GB version coming next month.

Western Digital has a habit of separating its wide range of storage solutions by color with each color designed for specific markets. The Black, Blue, and Green series, for example, cater to performance enthusiasts, mainstream users, and budget builds, respectively. The lesser-known WD Purple series caters to enterprise users where reliability and sustainability are of utmost importance.

The new WD Purple MicroSD card is not very impressive in terms of sequential read and write speeds. At just 80 MB/s and 50 MB/s, respectively, the UHS-I card pales in comparison to the ~275 MB/s speeds offered by UHS-II-compatible models. Instead, the WD Purple MicroSD card is guaranteed to last for up to 1000 write cycles in a wide operating range of -25 C to 85 C. The manufacturer intends to market the card for both indoor and outdoor surveillance systems where environmental fluctuations are common.

The Purple MicroSD card is now shipping in a 32 GB capacity with a 64 GB version expected in May. Prices are very competitive with consumer-class MicroSD cards at $19 and $32 USD for the 32 GB and 64 GB sizes, respectively.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
