未必關張咭事

一般相機 60 WRITE 夠用

SD CARD 係消耗品同跌價快, 你買你現時適用的就夠了, 換機先再諗. 或者你換A7000 A8000 呢, 張咭已經唔夠快.

最近用100d,入張普通 Toshiba 40mb/s read c10落去,影一秒﹙4張﹚就開始慢
如果想 buffer冇咁快滿, Toshi ...

SD卡對buffer幾耐滿... 真係影響唔大... 最多俾多一、兩張buffer你
主要影響係buffer滿左之後既寫入速度

仲有, 100D係入門機, 寫入速度未必有咁快.... 師兄果張Toshiba write speed係幾多?

將來用A6000? 幾耐之後既將來呢?

見人用張快卡,影成8秒都keep到4fps﹙100d﹚,我一秒後就已經慢緊

會唔會係人地影JPG, 師兄影RAW?

入門機WRITE 應該不過 4X MB/S, 所以 60 夠用.

見到有網站咁寫

Canon specify that using a high speed UHS-1 SD card the SL1 has a buffer size of around 1140 full size JPEGs or around 8 RAW images. So going for the fastest card gives a significant gain in the number of JPEG images you can shoot before filling the buffer (27 to 1140), but only a small increase in the buffer capacity for RAW images (6/7 to 8).

另外
With the EOS SL1 / 100D set to Large Fine JPEG, I fired-off 36 shots in 8.7 seconds, corresponding to a speed of 4.1fps; the buffer took four seconds to completely clear. Switching to RAW, I managed seven shots in 1.49 seconds, corresponding to a speed of 4.7fps; this time the buffer took six seconds to completely clear. Finally setting the camera to RAW plus Large Fine JPEG saw the camera capture four shots in 0.98 seconds, corresponding to a rate of 4.1fps, while the buffer took five seconds to completely clear.

可見8秒連拍似乎係JPG速度, 而秒半左右就係RAW既速度, 而一秒就係RAW+JPG... (佢用一張Extreme UHS-I... 應為R95W60)

唔知樓主係用邊個setting (JPG, RAW, RAW+JPG)?

其實又唔駛計太多, 快咭會好少少, 起碼用晒BUFFER 得慢起黎, 唔會一秒一兩張, 可以做番一秒三張, 如果SD CARD 快可以提昇到速度, 幾十蚊值得俾. 不過講緊 20MB / 45MB D 的比較.

咁買 45/60/90 WRITE 好呢, 自己睇性價比, 45 其實夠用, 60 就可能升下一代機都用得盡 (但其實去到6D 都係 40 左右), 90 其實買黎完全用唔到就唔太值, D 錢用黎津貼買多張咭好過.

相機WRITE SD 有幾快, 我通常 GOOGLE 一下, 買到O岩O岩超過少少就夠了, sd card 速度, 大細FILE 順唔順sequence 都有影響, 買 60 會保證不同情形都達到 40 write.

我都知60夠用, 我只係想問樓主係咪用緊RAW+JPG去同人地JPG比較姐
