장기 저장용 카드를 고르는 방법

Choose a Realistic Capacity
For documents, 64GB to 128GB can be enough. For photos, videos, and laptop overflow storage, 128GB to 256GB is more practical. Be careful with unusually cheap cards claiming extreme capacity.
Use the Right Reader
A good SD card can still feel slow through a poor reader. Use a USB-C card reader or hub that supports your laptop and the card formats you actually use.
Keep Two Copies
No SD card should be the only home for important files. For long-term storage, keep one working card and one separate backup on a USB drive, laptop, or cloud storage.
자주 묻는 질문
What is the best SD card for long-term storage?
A branded Class 10 or UHS-1 card with realistic capacity is a good starting point. For important files, reliability and a second backup matter more than maximum capacity.
Can I use a micro SD card for laptop storage?
Yes, if your laptop has a micro SD slot or you use a reliable USB-C card reader. It works well for documents, photos, media libraries, and overflow storage.
Are SD cards safe for permanent backup?
They are useful for portable storage, but no single SD card should be your only backup. Keep at least one duplicate copy on another device or service.
