SSD vs HDD Performance

Understanding the Differences

Solid State Drives (SSDs) and Hard Disk Drives (HDDs) store data differently. HDDs use spinning platters and read/write heads, while SSDs use flash memory. This fundamental difference leads to significant performance variations.

• HDDs: Mechanical parts make them slower and more susceptible to damage.
• SSDs: No moving parts, offering faster access times and improved reliability.

Performance Metrics

Metric	HDD (Typical)	SSD (Typical)
Read Speed	80-160 MB/s	300-550 MB/s
Write Speed	50-120 MB/s	350-700 MB/s
Latency (Access Time)	5-10 ms	0.1-0.3 ms
Power Consumption	Higher	Lower

Conclusion

While HDDs remain a cost-effective option for bulk storage, SSDs are significantly faster and provide a much more responsive computing experience. For performance-critical applications like gaming, video editing, and operating system boot times, SSDs are strongly recommended.
