It then copies the data into this block, and deletes it from the temporary holding space. If your drive is heavily fragmented, this can take a very long time. Modern file systems - the rules computers use to organize their writes to the disk - are also designed to avoid fragmentation. It recognizes the difference between hard drives and SSDs, and allows you to TRIM your SSDs - a sister process to defragmentation that empties all the space once taken up by deleted data and gets it ready for reuse.
This again improves performance, as otherwise it would need to be done just before new data was written. In addition to ensuring your Windows machine is regularly defragged and running optimally, we also recommend defragging your external hard disk drives HDDs.
If you use your external HDD frequently for saving and accessing programs and data, this is especially important to maintain. In contrast, you do not need to run defragging software on a flash drive also known as a jump, USB or thumb drive or on an external SSD. On a side note, you can save your disk defragmenter software onto an external drive. Keeping your software stored externally can be convenient in case your computer crashes, or in case you travel frequently and want to run the software on multiple computers.
You may be curious why this is, but the answer is fairly simple: the file system within a Mac hard disk drive HDD is designed differently from one on a Windows computer. New Mac OS versions automatically check for fragmentation every time you access a file or program. However, we recommend periodically going through your hard drive to delete old or unwanted files and programs to keep as much space available as possible, or to purchase a larger HDD that better suits your storage needs.
These generally replicate a lot of the native functions, but add more of their own, particularly in the form of SSD optimisation tools that go beyond TRIMming. Whether you need them or not, will depend entirely on individual use cases. Macs in particular have a habit of not defragging properly if the drive is too full. Ease of use What you really want is a program you can set going, and which runs in the background, not bothering you until it announces it has finished. Some have different options for you to set, but we discovered that all of the apps on test provide comparable results if left on their default settings.
Scheduling Being able to defrag outside of your work hours is important if you depend on squeezing every FLOP of power out of your rig. There is a performance penalty, both in terms of processor availability and disk bandwidth, but many users will never notice it. Other scans Alongside defragmentation, programs may offer registry or driver scans.
The same goes for drivers, especially since Microsoft has moved to a new driver architecture that isolates them from the rest of the system. One thing driver scans are useful for, however, is identifying which drivers have updates available. You have full control over when your disk defragmenter program runs — you can put it on a schedule or use it manually whenever you need.
Both options have pros and cons, and learning the benefits and downsides to each can help you use the software the most effective and efficient way for your situation.
Instead, you can rest assured that your hard drive is optimized. Moreover, the process of erasing and moving data requires "flashing" the memory cells with high voltage. That gradually wears out the SSD. Second, Windows 7's new "trim" feature will improve performance in three ways. It will reduce the amount of data to be deleted, which improves the SSD's lifespan; delete garbage data in advance, which speeds up writing of data; and maximize the amount of unused data, which helps even out the wear and tear on the SSD, Shu said.
This requires Windows 7 to be installed fresh and not upgraded from XP, he said, since the latter operating system formats SSDs in an inefficient way. Finally, Microsoft plans to create a certification program for SSDs. To win the software maker's logo of approval, SSDs must identify themselves to Windows 7 properly, prioritize data reads over slower data writes, comply with the Serial ATA SATA drive interface for faster connections and more, Shu said.
On the other hand, Microsoft is not taking more radical steps. For instance, it's not trying any tricks to decrease the number of times data is written, such as using RAM to cache data, Shu said. To perform a thorough check, select Scan for and attempt recovery of bad sectors.
This scan attempts to find and repair physical errors on the drive itself, and it can take much longer to complete. To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.
Depending on the size of your drive, this might take several minutes. For best results, don't use your computer for any other tasks while it is checking for errors. If you select Automatically fix file system errors for a drive that's in use for example, the partition that contains Windows , you'll be prompted to reschedule the check for the next time you restart your computer.

Both are pretty much the same, depends when you need it. Redestium Posted April 19,
