| Vocabulary | Part of Speech | Simple Definition | Example Sentence(s) |
|---|---|---|---|
| Hard Disk Drive (HDD) | Noun | A traditional storage device that uses spinning platters and read/write heads to store data. | My old computer still uses a Hard Disk Drive (HDD) for its main storage. |
| Solid State Drive (SSD) | Noun | A modern storage device that uses flash memory chips to store data, offering faster performance than HDDs. | Upgrading to a Solid State Drive (SSD) significantly improved my laptop's boot time. |
| Capacity | Noun | The amount of data a hard drive can store, usually measured in gigabytes (GB) or terabytes (TB). | This external hard drive has a capacity of 2 terabytes. |
| Read Speed | Noun Phrase | The speed at which data can be retrieved from a storage device. | The read speed of this SSD is much higher than my old HDD. |
| Write Speed | Noun Phrase | The speed at which data can be saved to a storage device. | For video editing, a high write speed is crucial. |
| Interface | Noun | The connection type used by a hard drive to communicate with the computer's motherboard (e.g., SATA, NVMe). | Modern SSDs often use the NVMe interface for maximum performance. |
| Form Factor | Noun Phrase | The physical size and shape of a hard drive (e.g., 2.5-inch, 3.5-inch, M.2). | Laptops typically use a 2.5-inch form factor for their drives. |
| Cache/Buffer | Noun | A small amount of fast memory on a hard drive used to temporarily store frequently accessed data. | A larger cache can improve the drive's responsiveness. |
| RPM (Revolutions Per Minute) | Noun | For HDDs, the speed at which the platters spin, affecting performance. | A 7200 RPM HDD is faster than a 5400 RPM one. |
| Fragmentation | Noun | The condition where files are stored in non-contiguous blocks on an HDD, slowing down access. | Fragmentation can be resolved by defragmenting the drive. |
| S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) | Acronym/Noun | A monitoring system included in hard drives to detect and report on various indicators of reliability. | S.M.A.R.T. data can predict potential drive failures. |
| Sector | Noun | The smallest physical storage unit on a disk. | A bad sector on the hard drive can lead to data loss. |
| Partition | Noun/Verb | A logical division of a hard drive that is treated as a separate unit by the operating system. | I created a new partition to install a different operating system. |
| Latency | Noun | The delay before a transfer of data begins following an instruction for its transfer. | SSDs have much lower latency compared to HDDs. |
| TBW (Terabytes Written) | Acronym/Noun | A measure of SSD endurance, indicating how much data can be written to the drive over its lifetime. | This SSD has a TBW rating of 600, which is excellent for its capacity. |
