The drive performs better if it spins faster.
Performs better when it's moving faster.
The data transfer speed of a device is not fully dependant on its size. With certain file systems, larger drives will perform slower because of the way the files are stored; this is why NTFS is used rather than FAT32 for large hard drives. However; the size of the drive is not the biggest factor in speed. For example, a 7200 RPM drive is usually faster than a 5400 RPM drive, even if the 7200 RPM drive is much larger in storage size.
Definitely faster if it's sequential. That's why you should periodically defrag.
no a hard drive has a much faster access time...
A higher capacity drive does not inherently perform faster or slower than a lower capacity drive; performance depends on various factors such as technology (HDD vs. SSD), read/write speeds, and interface (e.g., SATA vs. NVMe). In general, SSDs tend to offer better performance than HDDs, regardless of capacity. That said, within the same technology type, capacity might not significantly impact speed, but higher capacity drives could benefit from advanced caching or parallelism that may enhance performance.
5 hours at 50 mph Faster, shorter Slower, longer
Within reason, driving slower is better because you have more time to react. However, it is not better to drive a great deal slower than the traffic around you, because the others will be passing you at higher speed or backing up behind you.
At 100 kph, it will take 3 hours. Faster, shorter. Slower, longer.
Sequentially
It has to be a 2.5 SATA drive but apart from that it can be any drive. Faster spinning drives generate more heat and will deplete the battery slightly faster than a slower drive. Apple has guides for disc replacements (See links below).
a solid state drive is faster than an sata drive...
Thumb up for faster Thumb down for slower
