A write cache can improve computer performance but what risk does it introduce?

Answer and explanation

Correct answer: Data not yet written to storage may be lost during sudden power failure

The governing concept is delayed or buffered writing. A write cache temporarily keeps recently written data in faster memory before sending it to the storage device, improving responsiveness. If power fails or the system crashes before the data is committed, those pending changes may be lost or a file may become inconsistent. Option A states this risk; the other options are unrelated hardware effects.
