Storage Devices practice questions

2.5-inch SATA SSD

Why wrong: SATA SSDs are faster than HDDs but slower than NVMe, making them less ideal for demanding video editing.

10,000 RPM HDD

Why wrong: Even a fast HDD is much slower than any SSD and would bottleneck video editing performance.

Hybrid drive (SSHD)

Why wrong: SSHDs have a small SSD cache but still rely on HDD platters for bulk storage, not matching NVMe speeds.

One of the SSDs is not detected by the system.

Why wrong: If one drive was missing, the array would likely fail or show errors, not just reduced capacity.

The SSDs are different brands and incompatible.

Why wrong: Different brands of SSDs can be used in RAID as long as they are the same size and interface.

The operating system does not support RAID 0.

Why wrong: Most modern operating systems support RAID 0; this is not a common limitation.

NVMe M.2 SSD

Why wrong: NVMe M.2 SSDs use a different interface (PCIe) and form factor, requiring an M.2 slot, not a SATA port.

mSATA SSD

Why wrong: mSATA is a smaller form factor used in some older laptops, but it is not a standard replacement for a 2.5-inch drive.

External USB SSD

Why wrong: An external drive would be slower and cannot be used as the primary internal boot drive without modification.

Install a SATA SSD in an available 2.5-inch drive bay.

Why wrong: This adds storage but does not use the M.2 slot; however, it is a valid option, but the question asks for the best solution without sacrificing performance, and NVMe is faster.

Use an external USB SSD for additional storage.

Why wrong: External drives are slower and not internal, making them less ideal for primary storage expansion.

Add a second M.2 drive using a PCIe adapter card.

Why wrong: This is possible but may not be supported by all motherboards and could be more complex than a simple replacement.

The CPU is overheating and throttling performance.

Why wrong: CPU overheating can cause slowdowns, but it would not cause the drive light to be constantly active.

The system has a virus that is encrypting files in the background.

Why wrong: While a virus could cause activity, it is less common than hardware failure and would not specifically cause constant drive light activity during idle.

The RAM is insufficient and the system is using the hard drive as virtual memory.

Why wrong: Low RAM can cause paging, but it would not cause constant drive activity during idle unless the system is actively swapping.

Use a USB-to-SATA adapter and connect the drive externally.

Why wrong: This would make the drive external, not internal, and may be slower than SATA.

Replace the motherboard with one that has more SATA ports.

Why wrong: This is overly expensive and time-consuming when a simple expansion card will work.

Use an external hard drive enclosure connected via USB.

Why wrong: This makes the drive external, not internal, and may have performance limitations.

All data is lost because RAID 5 cannot handle any drive failures.

Why wrong: RAID 5 is designed to survive a single drive failure without data loss.

The usable capacity drops to 2 TB until the drive is replaced.

Why wrong: Usable capacity remains 4 TB; only redundancy is reduced until the drive is replaced.

The array automatically switches to RAID 0 to maintain performance.

Why wrong: RAID arrays do not change RAID levels automatically; the array remains in RAID 5 degraded mode.

No, the array should show 8 TB because the drives are identical.

Why wrong: RAID 1 does not combine capacity; it mirrors data, so total usable space is only the size of one drive.

No, the array should be configured as RAID 0 to get 8 TB.

Why wrong: RAID 0 would combine capacity but offers no redundancy, which is not the goal for this server.

Yes, but only if the drives are set as JBOD.

Why wrong: JBOD (Just a Bunch of Disks) would combine them without redundancy, but RAID 1 specifically mirrors.

The SATA cable is faulty.

Why wrong: A faulty cable would typically cause the drive not to be detected at all, not just a boot error.

The SSD is not compatible with the motherboard.

Why wrong: Most SATA SSDs are universally compatible with SATA ports; incompatibility is rare.

The SSD needs to be formatted before use.

Why wrong: An unformatted drive would still be detected; the OS would not be found only if the OS is not installed.

The external drive is failing and needs to be replaced.

Why wrong: A failing drive would likely show errors or disconnections, not just slower speeds.

The drive is formatted with FAT32, which limits transfer speeds.

Why wrong: FAT32 does not limit transfer speeds; it only has a 4 GB file size limit.

The computer's USB drivers are outdated.

Why wrong: While outdated drivers could cause issues, they typically result in no detection or errors, not a consistent speed drop.

One SATA III SSD for the OS and one SATA III HDD for media files.

Why wrong: While this separates OS and data, both drives are limited by SATA III speeds, which is insufficient for 4K video editing.

Two SATA III SSDs in RAID 0.

Why wrong: RAID 0 with SATA III SSDs can improve performance, but total throughput is still limited by the SATA interface and may not match a single NVMe drive.

One SATA III SSD for the OS and one NVMe M.2 SSD for media files.

Why wrong: This is a good configuration, but the question asks for the best performance; using the NVMe drive for both OS and media is simpler and equally fast.

Run CHKDSK to repair file system errors.

Why wrong: Running CHKDSK on a failing drive can cause further damage or data loss; data backup should come first.

Replace the hard drive immediately.

Why wrong: Replacing the drive without first backing up data will result in permanent data loss.

Update the hard drive firmware.

Why wrong: Firmware updates are rarely the solution for physical failure symptoms like clicking noises.

The USB cable is too short.

Why wrong: A shorter cable actually reduces resistance and improves power delivery, so this would not cause the issue.

The front USB ports are not connected to the motherboard.

Why wrong: If the front ports were disconnected, no USB device would work there, but the drive works on the back ports, ruling this out.

The hard drive is formatted with the wrong file system.

Why wrong: File system incompatibility would prevent recognition on any port, not just the front ones.

Use a Y-splitter on the existing SATA data cable to connect both drives.

Why wrong: SATA data cables cannot be split; each drive requires a dedicated data connection to the motherboard.

Connect the second drive using an external USB-to-SATA adapter.

Why wrong: An external adapter is a workaround, but it is less practical and may be slower than an internal SATA connection.

Replace the existing hard drive with a larger one.

Why wrong: Replacing the existing drive does not add a second drive; it only increases capacity of one drive.

Update the SSD firmware.

Why wrong: Firmware updates are not the first step; the drive is not detected at all, indicating a hardware or configuration issue.

Replace the SSD with a different brand.

Why wrong: Replacing the drive is premature without verifying slot compatibility first.

Disable Secure Boot in the BIOS.

Why wrong: Secure Boot does not affect detection of a storage device in the BIOS.

Cut and paste the Users folder to the HDD, then create a shortcut on the SSD.

Why wrong: Cutting and pasting system folders will break file paths and cause errors; shortcuts do not redirect system access.

Format the HDD as a dynamic disk and extend the C: partition onto it.

Why wrong: Extending a boot partition onto a different physical drive is risky and not supported for system drives in Windows.

Delete the pagefile on the SSD to free space.

Why wrong: Deleting the pagefile may free some space but does not address the user's need to move data to the HDD.

Another 5400 RPM HDD with a larger cache

Why wrong: While a larger cache helps slightly, a 5400 RPM HDD is still much slower than an SSD and consumes similar power.

A 10,000 RPM HDD

Why wrong: A 10,000 RPM HDD is faster but consumes more power and generates more heat, which is not ideal for a laptop.

An external USB flash drive

Why wrong: An external drive is not suitable as an internal boot drive and would be slower due to USB interface limitations.

The USB port is faulty.

Why wrong: If the USB port were faulty, the drive would not appear in Device Manager at all.

The drive needs a new driver.

Why wrong: Most external drives use generic USB mass storage drivers; a driver issue would likely cause an error in Device Manager.

The file system is corrupted.

Why wrong: A corrupted file system would cause the drive to appear in Disk Management with an unallocated or RAW status, not necessarily prevent it from appearing in Device Manager.

A single 2TB 7200 RPM HDD

Why wrong: A single HDD, even at 7200 RPM, cannot match the read performance of a striped array.

Two SSDs in RAID 1 (mirroring)

Why wrong: RAID 1 provides redundancy but does not improve read performance; it may even slightly reduce write performance.

A single NVMe SSD

Why wrong: A single NVMe SSD is fast, but RAID 0 with two SSDs can provide even higher sequential read speeds.

The new drive has a different sector size (4K vs 512e).

Why wrong: Sector size mismatch can cause performance issues or incompatibility, but it would not result in a 0.2TB capacity loss.

The RAID controller is using some space for metadata.

Why wrong: RAID metadata uses a negligible amount of space, not 200GB.

The RAID 5 array is degraded and needs a second drive to be replaced.

Why wrong: A degraded array would still show full capacity (2TB) once rebuilt; the issue here is capacity, not redundancy.
