Memory Cards in Bangladesh
Professional recording media — Sony SxS (এসএক্সএস) for XDCAM camcorders, plus CFexpress, SD and microSD from Sony and SanDisk.
Recording media is the component most likely to fail in a working kit, because it is the only part being written to continuously. It is worth buying carefully.

Buying recording media safely
Sustained write speed, not peak. A card can burst fast and then slow as its buffer fills. On a long take that shows up as a dropped frame or an aborted clip.
Check the slot, not the brand. Sony has shipped XDCAM bodies with SxS slots, SD slots, both, and neither. The slot decides the card.
Two smaller cards beat one large one. One card is a single point of failure and no way to keep shooting while you offload.
Counterfeit professional media is real — usually a slower part relabelled with a higher capacity. It passes a casual copy test and fails during a long record.
