Final answer:
HDDs use magnetic storage with spinning disks, whereas Race Track Memory uses nanowires without moving parts, potentially offering faster speed, more reliability, more durability, and higher data density. Improving domain wall velocity in RM would increase the speed of data access, making it even faster.
Step-by-step explanation:
Difference Between HDD and Race Track Memory
The primary difference between a Hard Disk Drive (HDD) and Race Track Memory (RM) is in their design and operation. HDDs use magnetic storage principles, where data is written onto a spinning disk using a read/write head. Conversely, Race Track Memory uses nanowires to store data as a series of magnetic domains, without any moving parts.
Advantages of Race Track Memory Over HDD
- Speed: RM has the potential to be faster than HDDs because it does not rely on moving parts.
- Reliability: Since RM does not have moving parts, it's less prone to mechanical failure.
- Durability: RM could potentially withstand more physical shock compared to HDDs.
- Size: Race Track Memory has higher data density and could result in smaller storage devices.
Improving Domain Wall Velocity
Improving domain wall velocity would be beneficial as it would increase the speed at which data can be read and written in Race Track Memory, leading to faster memory devices.
