220-801 Question #944: Real Exam Question with Answer & Explanation

The correct answer is D: Solid State Drive. Solid State Drives (SSDs) are significantly faster than any mechanical hard drive for boot and general workstation use. SSDs use NAND flash memory with no moving parts, delivering read/write speeds many times faster than traditional spinning disk drives. A typical SATA SSD reads

Question

Joe, a client, wants to purchase a new hard drive to replace the boot drive in his workstation. Joe wants the fastest performance for the new boot drive. Which of the following drive types should be selected?

Options

ASCSI Drive
B7200 RPM SATA
C10K RPM SATA
DSolid State Drive

Explanation

Solid State Drives (SSDs) are significantly faster than any mechanical hard drive for boot and general workstation use. SSDs use NAND flash memory with no moving parts, delivering read/write speeds many times faster than traditional spinning disk drives. A typical SATA SSD reads at 500+ MB/s, while a 10K RPM SATA drive reads at roughly 120-150 MB/s. SCSI and 7200/10K RPM SATA drives all rely on spinning platters, which introduce rotational latency and seek time - physical limitations SSDs completely eliminate. For a boot drive, SSD delivers dramatically faster OS load times and application launches.
