Important information about SSD speeds

Some SSD models cannot record video data at manufacturers' suggested speeds. This is because the disk uses confidential data compression to write at higher speeds. This data compression can save data at the manufacturer's claimed speeds while only storing blank data or simple files. Compression doesn't help much as video data contains more random video noise and pixels, thus revealing the actual speed of the disc.

Write speeds of some SSDs may be as slow as half of the manufacturer's suggested speeds. So even if the disk specs say SSD speed is sufficient to run video, when used for real-time video recording, this disk is actually not fast enough to record video data.

Use the Blackmagic Disk Speed Test to accurately measure whether your SSD is fast enough for high data rate video recording and playback. Blackmagic Disk Speed Test uses data to simulate the storage of video so you get results similar to what you would see when saving video to a disc. During testing at Blackmagic Design, we found that newer and larger model SSDs and SSDs with larger capacity are generally faster.
