Transcend High Capacity SD/SDHC Flash: HD110, HD210, HD410, HD810, HD1010
Three customers have reported problems using 8 - 32GB SDHC cards from Transcend. We are currently working on a software workaround to avoid this firmware problem on the cards. Customers have reported the following symptoms:
-Longer than expected startup times
-IO errors on serial output
-Errors reading or writing to cards on a mac or pc
-Playback glitches
Compact Flash: HD600, HD2000
Although the Compact Flash interface is standardized, there are a wide range of performance, compatibility, and reliability issues with different CF card brands and models. Roku strongly recommends that you use "industrial rated" CF cards and that you test CF cards to verify they perform up to specs before deploying.
SD/SDHC Flash: HD110, HD210, HD410, HD810, HD1010
Although the SD/SDHC interface is standardized, there are differences in performance and reliability among various card brands and models. Brightsign strongly recommends that you use SD/SDHC cards that support Wear Leveling and use SLC flash chips. Most newer cards support wear leveling, and many card vendors, like Kingston (Ultimate and Elite Pro series) and ATP (Industrial and Promax II series), use SLC flash chips in some products.
Note: If you are playing back High-Bitrate HD video, we recommend a minimum of 4 Megabytes per second throughput.
