A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. It emulates a hard disk drive interface. It's a high-performance plug-and-play storage device that contains no moving parts. We're starting to see more of them, particularly in laptops, but right now they are quite pricey. Predictions vary as to when SSDs will become more mainstream, but their popularity is going to increase as prices do come down.
PerfectDisk 10's defrag engine, as well as earlier versions, works just fine with SSD. As a matter of fact, the design of PerfectDisk has been tailored for SSDs for years because of PerfectDisk's Space Restoration Technology, with its single-pass free space consolidation.
PerfectDisk helps improve the performance of SSD drives' write performance through its free space consolidation. To write a sector, the file system needs to read and merge the data, then erase and write back a data block, which is bigger than a sector, called an "erase block." The size of the sector is 1 - 4MB, which is much bigger than the sector size. By consolidating free space, the process of transferring data between erase blocks can be reduced or eliminated. As a Microsoft Certified defragmenter, PerfectDisk's use of Microsoft's defrag APIs ensures that defragmentation takes place in a safe manner.
Now, if PerfectDisk had not pioneered total single-pass free space consolidation, we might do things differently. We might put together an extra or special component and charge extra for it. But in our mind, that would be like selling a car and charging extra for breaks. We'll leave that to others.
Complete and safe SD support - standard with PerfectDisk 10.
