![]() ![]() Optimizing a conventional hard drive puts the files you use most often close together, so again the heads don't spend so much time jumping around.įlash memory doesn't have the same physical limitations as a conventional hard drive, so the physical location of the sectors making up a file are irrelevant. At the same time all files are consolidated towards the beginning of the partition - why you'd run a defrag before shrinking the size of a partition. Defragmenting a conventional hard drive moves the sectors making up each file so that they're *physically* in sequence. If the sectors making up a file are scattered about all over that storage area, those heads can have a lot of jumping around to do just to read that one file. On a conventional hard drive read/write heads move back and forth to access all of the storage area on the circular platters where data's stored. Windows uses the FAT32 &/or NTFS file systems, which store data in small chunks - when it writes a file to disk, it fills up one sector, then the next, then the next & so on until all the data is written & stored. They use Windows itself to do the actual work - deciding what goes where, and how long it takes to analyze the files & make those decisions, can vary from one defag app to the next. ![]() I think iObit's Smart Defrag is one of the more popular defrag apps out there, which differ mainly in how they decide what files should go on the fastest part of a conventional hard drive partition. So, garbage collection ensures that SSDs used for Windows XP and other operating systems which lack TRIM will still be tuned up and keep running smoothly. This feature operates like TRIM except that it is activated periodically by the drive's own controller software rather than by Windows every time you delete something and the computer is idle for a few moments. Another point worth mentioning is that almost all SSDs have a built-in feature called garbage collection. ![]() Third, today's Giveaway is surely aimed at Windows XP users due to its lack of TRIM and its less efficient defragmenting. Second, Windows 10 optimises your drives by default which may, at times, include some defragging of your SSD. In other words, most users will rarely, if ever, need to defragment an SSD. so that a considerable amount of fragmentation has occurred. ![]() In fact, because access time to data stored on an SSD is many, many times faster than access on a spinning hard drive there is only a slight benefit to defragging an SSD and that would only be if the drive is largely filled up and you had installed and uninstalled a lot of programs, games, etc. First, it's OK to defragment an SSD, but it should NOT be done often. ![]()
