Transcend`s 4GB SDHC 150X card was chosen as "the most recommended SDHC card " in a recent memory card review titled "Pentax K20D/K200D Perfect Guide" published by Impress Japan. The editors praised Transcend's 4GB SDHC 150X card for its fast write speeds and superior continuous shooting reaction time, outperforming competing models' write speed with both JPEG and RAW data. In testing, Transcend's card was able to shoot 22 pictures continuously with the Pentax K20D, which was the best result amid 12 memory card entries. The editors commented, "Most memory cards showed different speeds when writing JPEG and RAW data. However, Transcend performed the same when writing either JPEG or RAW data. Due to its excellent stability, Transcend`s 4GB SDHC 150X card is our most recommend 4GB SDHC card for the Pentax K20D/K200D."
