SanDisk Extreme Pro. The new king of SanDisk’s line, this card reached 6.7 fps with an effective throughput of 34 MB/sec.

PhotoFast 533x Plus. This little-known card hit 6.7 effective fps with an impressive 31 MB/sec throughput.

San Disk Extreme Ducati Edition. This card initially topped the performance list with an effective 6.7 fps and nearly 29 MB/sec throughput.

Transcend Extreme Plus. This card equaled the Ducati, achieving 6.7 fps and almost 29 MB/sec throughput. A real contender.

San Disk Extreme IV Series. The two cards I tested – 8GB and 2GB – were just behind the Ducati and averaged an effective 6.3 fps and approximately 28 MB/sec.

A级别

Pretec 667x. Respectable 5.5 effective fps with a 25/MB sec transfer rate.
Sony UDMA 300x. This card fared somewhat better in RAW shooting than for JPG, coming in at 5.5 effective fps and 24 MB/sec.

PhotoFast 533x. The standard version of the 533x performed well, with an effective fps rate of 5.5 and 24 MB/sec throughput.

PNY Optima Pro. This card averaged an effective 5 fps and 24 MB/sec throughput. Both the PNY and Extreme IV cards topped the performance charts for JPG burst shooting as well.

Transcend 300x UDMA. Transcend’s newest UDMA card hit an effective 5 fps and 24 MB/sec.

Lexar Pro UDMA. The Lexar edged into the top performance tier for RAW shooting, with an effective 6 fps and 23 MB/sec throughput.

Pretec 433x. Despite its official claim, this card doesn’t approach its listed speeds of 65 MB/sec read and 50 MB/sec write in real world testing. It clocked 5.5 effective fps and 23 MB/sec.

Hoodman RAW 300X. While a marked improvement over its 280X predecessor, this card only managed 5.5 effective fps and 23 MB/sec throughput in the burst test.

SanDisk Extreme III 30MB/sec. The upgraded, UDMA-capable Extreme III series clocked in at an effective 5 fps and 23 MB/sec throughput.

ATP Pro Max II UDMA. A pleasant surprise, the ATP card — an also-ran in JPG burst shooting – joins the RAW shooting journeymen with an effective 5 fps and 22 MB/sec throughput.

Pretec 333x. Another also-ran in JPG shooting, the faster of Pretec’s original two UDMA models consistently recorded 5 fps and 22MB/sec in our RAW burst test.

Lexar Professional 233x. Lexar’s newest UDMA card achieved a consistent 5 fps with 21 MB/sec throughput.

A-Data Turbo 350x. More proof than manufacturer specs means little, this card reached a merely respectable 5 fps and 20 MB/sec throughput. It’s much better than their “266x” card but not as good as 300x cards from Lexar and Transcend, either.

B级——注意Sandisk新出的标称“60MB/s”的新EXTREME赫然在列，当然测试不排除个体差异，数据仅供参考

SanDisk Extreme. This so-called “60 MB/sec” card reached a measly 4 fps effective and 18 MB/sec throughput, earning this overpriced dog a spot on the Crap List.

Kingston 266x Ultimate. The Kingston led a pack of cards whose performance was a bit disappointing, at just 4 fps effective and 14 MB/sec throughput.

Ridata 266x Supreme. Ridata’s second effort reached 4 fps and 14 MB/sec throughput.

Apacer Steno IV 300x. This entry hit 3.75 effective fps with 14 MB/sec throughput.

Transcend 266x. Transcend’s faster UDMA card hit 3.75 effective fps and 13 MB/sec throughput.

Delkin Pro UDMA 305x. Delkin’s card just topped 3.5 effective fps and nearly 12 MB/sec.

Hoodman RAW 280X. Hoodman’s card limped in at 3.3 effective fps and 11 MB/sec throughput.

Calumet ProSpec 305x. This very likely re-badged card has mediocre specs equal to the Hoodman RAW 280X.

BiWin 150-300x. This 16GB monster struggled to reach 2.9 effective fps and a 9 MB/sec throughput rate.

A-Data Turbo 266x. A-Data was sucking wind at 2.7 fps and 11 MB/sec
