Read the first 7 Storage Solutions & Management flashcards as text

  1. Which file system is most commonly recommended for external drives shared between Windows and macOS computers?

    Answer: exFAT

    exFAT is natively supported by both Windows and macOS without additional software and supports files larger than 4GB.

  2. A customer complains that their new 2TB hard drive shows only 1.86TB available in Windows. What is the most likely explanation?

    Answer: Drive manufacturers use decimal (1,000-based) GB while Windows reports binary (1,024-based) GB

    Drive manufacturers measure 1TB as 1,000,000,000,000 bytes, while operating systems calculate using powers of 1,024, creating an apparent size discrepancy.

  3. Which storage media is most appropriate for archiving data that will rarely be accessed but must be kept for 30+ years?

    Answer: Magnetic tape (LTO)

    LTO magnetic tape has a rated archival life of 30+ years and extremely low cost per terabyte, making it the industry standard for long-term archiving.

  4. What is 'wear leveling' in the context of SSD storage?

    Answer: An algorithm that distributes write operations evenly across NAND cells to extend lifespan

    Wear leveling spreads write and erase cycles across all memory cells evenly so no single cell wears out prematurely, extending the SSD's overall lifespan.

  5. A customer running a video editing workstation needs the fastest possible internal storage. Which interface should you recommend?

    Answer: PCIe 4.0 NVMe SSD

    PCIe 4.0 NVMe SSDs offer sequential read speeds up to 7,000 MB/s, far exceeding SATA's 600 MB/s ceiling for demanding video editing workflows.

  6. What does 'TBW' (Terabytes Written) indicate on an SSD specification sheet?

    Answer: The total data that can be written to the drive over its lifetime

    TBW is an endurance rating that indicates how many total terabytes of data can be written before the SSD is expected to fail.

  7. Which scenario best demonstrates the proper use of a USB flash drive vs. an external HDD?

    Answer: Flash drive for carrying a presentation to a meeting; HDD for storing a large media collection at home

    Flash drives excel at portably transporting small files like presentations, while external HDDs are better suited for storing large media libraries due to their higher capacity.
