But if you use your computer on a daily basis, I challenge you to install Diskeeper trialware and see for yourself. If you hardly use your computer, you're right - the numbers won't be that impressive. For every piece of the file that's retrieved, an additional I/O request needs to be generated - and they add up.ĭiskeeper ensures that files are written to the storage sequentially in one block of free space, so that it only takes one single I/O requests to circle back and read that file later. Now when Windows goes back to read this file, it generates what's called an "I/O request" to complete the action - and each of these I/O requests takes a measurable amount of time. In it's natural course of action, Windows will attempt to save this file in the first block of free space it comes across - even if the block is only 500KB in size! This means that Windows will continuing looking for other blocks of free space - breaking the file into many pieces on it's quest to get the entire file saved to the storage. Windows naturally writes files in an unorganized fashion and therefore the same holds true when you go back and read these files. The NTFS file system is basically the same as it's always been. Emerging technologies, such as that in our new V-locity 4 (acceleration software for virtual environments), actually allow us to predict file usage in order to take preventative measures before performance is impacted.ģ. Here's a different set of graphs that let the numbers do the talking and shows how Diskeeper decreases SSD wear and thus improves it's lifespan - Ģ. The scale-free graphs was meant to symbolize the dramatic difference between the two. ![]() Its ability to perform GC in a timely manner matters 100x more to performance than NTFS issues.ġ. If it's 2% slower one day than it could have been if it had been defragged, are you even going to notice? Remember that you're using a drive that can handle IOPS in the tends of thousands-figure ~200 pure 4K random per screen refresh on a bad day (steady state, QD 1-2). Just use the drive, leave some free space, and don't fret over it. Its ability to perform GC in a timely manner matters 100x more to performance than NTFS issues. If it's 2% slower one day than it could have been if it had been defragged, are you even going to notice? Remember that you're using a drive that can handle IOPS in the tens of thousands-figure ~200 pure 4K random per screen refresh on a bad day (steady state, QD 1-2). The common case is that it doesn't really matter. ![]() ![]() Common patterns can be planned for (appending to the end, FI), but you really need to handle it after the fact, in most cases. There are strategies for minimizing it, and dealing it is after the fact, but it occurs like it does because the OS can't know what files will be edited, or how. ![]() I've even been lazily leaving it with only 5-10% free space.įragmentation, both in NV storage and RAM, is real, but the problem is that it is difficult to predict. Hell, I left my spinner for almost 4 months w/o a defrag (idle activity annoys me to no end), and I had only a handful of files flagged as problematic. But it's gotten better, and you generally don't have to worry. NTFS is far from perfect, and Windows is far from perfect. Scale-free graphs! I love those things! They are so informative! A vendor's test, without disclosure of exactly how the test operates is pretty useless, too.
