Read vs write hdd
WebThere are rumors that SSD is more durable than HDD. To divide question into 2 different scenarios: === 1) When used in PC/Laptop === People say that SSD produced in recent years can last longer than HDD (if we consider the same amount read/write operations). Also, more durable when laptop drops. Is that true? === 2) When used as external drive === WebAug 24, 2024 · HDD – Sequential Reads Unfortunately, when reading larger chunks of data sequentially, using multi-threding actually hurts the throughput (Fig. 5). This is because the operating system interleaves the I/O requests coming from different threads and the HDD would have to reposition the heads frequently jumping from one file to another.
