![]() Now let’s say the file is fragmented, and the multiple data blocks belonging to a file are scattered around the platters. Sequential reads are always the fastest on magnetic hard drives. If you are trying to read a large file that is stored consecutively on the disk, the hard drive will only have to position the heads once, and read the content of the file by accessing consecutive sectors. In order to read data, the hard drive (assuming it’s already spin up) has to position the reading heads over a certain area on the platters (which takes time), wait while the heads stabilize (which takes time), then read information (which, again, takes time). Magnetic hard drives rely on spinning platters and moving heads to store information. To better understand what’s going on, let’s review the differences between magnetic and solid-state disks. A good advice for a mechanical hard drive can quickly run down the disk if applied to an SSD drive. Magnetic hard drives utilize completely different optimization techniques as compared to SSD drives. The two storage technologies, magnetic and solid-state, are worlds apart. One thing is for sure: what can be good for your hard drive can be deadly for an SSD, and vice versa. Today, we decided to sum up our experiences with hard drive optimization techniques, and figure out what to do and what to avoid. Whether experimenting with Windows registry tweaks or using a low-level defragmentation tool, these optimization attempts often end up in the hands of a data recovery company such as ours. ![]() ![]() Working in a data recovery company, we get to hear stories about people getting into trouble by trying to improve something. ![]()
