Secondary Storage: HDD and SSD

Secondary storage is vital for managing data, both at home and at work. Hard Disk Drives (HDD) and Solid-State Drives (SSD) are common types. Each has its benefits and limitations, making them fit for different uses.

Hard Disk Drives (HDD)

Hard Disk Drives have been around for a long time. They work by using spinning platters to store data magnetically. HDDs offer lots of storage, often in terabytes (TB), but are slower, moving data at 30–150 MBps. The speed of HDDs depends on how fast the platters spin, between 4200 and 7200 RPM, affecting performance.

Solid-State Drives (SSD)

On the other hand, Solid-State Drives store data electronically, boosting speed and efficiency. They have no moving parts, so they’re more robust and use less energy than HDDs. SSDs deliver fast data transfers, up to 3,500 MBps in newer models. This makes them quicker in reading and writing data, with speeds between 50–250 MBps.

Comparing HDD and SSD for Performance

There’s a significant difference in performance between HDD and SSD storage. Here’s a table summarizing their main features:
