How To Optimize Your SSD (Without Wearing Out Its Lifespan)

The SSD: To Defrag or Not To Defrag?

Overall, solid state drives are faster, quieter and they use less power than traditional hard disk drives since there are no electromechanical parts moving around, using up energy, and making noise. SSDs make memory-intensive activities, such as PC gaming, video editing and photo editing snappier than ever….that is, until free space becomes fragmented on the drive.





To Defrag or Not to Defrag an SSD

There has been a lot of discussion on whether one should or should not defrag an SSD and the consensus is in: Do not defrag your solid state drive. In fact, you can do more harm than good by performing a traditional defrag on an SSD:

  • Unlike HDDs, any write operation to SSD storage requires not one step, but two: an erase followed by the actual write.
  • SSD write performance degrades over time.
  • Since there is no mechanical seek time on an SSD, traditional file-based defrag really doesn’t provide any performance benefit.

No defrag? Then what does this have to do with PerfectDisk? Read on…

See how SSD Optimize improves wear-leveling and results in more effective TRIM operations.

Improving SSD Performance Without Wearing It Out

The new requirement for managing SSDs is a disk optimizer that identifies which drive is which – SSD or HDD – and then performs the appropriate actions for each drive.

What can provide a performance benefit to SSDs is free space consolidation. High free space fragmentation is a strong indicator that many partially full “untrimmed” blocks exist. PerfectDisk’s SSD Optimize eliminates free space fragmentation on the SSD and consolidates partially full blocks of data.

SSD Optimize for SSD Storage

PerfectDisk performs intelligent analysis automatically and utilizes sophisticated free space placement algorithms to enable peak SSD performance:

  • Consolidates free space on the drive without also performing a traditional defrag.
  • Identifies where the largest section of free space is located and consolidates free space in that location – regardless of whether it is at the beginning, middle, or end of the disk.

PerfectDisk’s SSD Optimize is able to maintain SSD performance over the long term without causing additional wear on the disk.

  1. As I understand, the consolidation means that the free space between the partially full “untrimmed” blocks is identified, and can later therefore be used for storing additional information? Without a special SSD optimization tool, like PerfectDisk, this potentially free space would be otherwise be wasted and not put to use? Thanks.

  2. Hi Dan,

    Thanks for the comment.

    Those SSD pages or “blocks” of data would not be included in any TRIM optimizations and thus would not have their performance restored. Depending on the concerns or priorities of who you ask, the bigger issue at hand is that those blocks would not contribute to the pool of free pages to be used for wear leveling purposes. Left unchecked, this would effectively reduce the life of the SSD over time. In the case where many small files are written and deleted on a regular basis, the impact on the life of the device could be significant.

  3. Some people argue that ‘normal’ file defrag may be beneficial on SSD as well because of file system overhead: very fragmented file has multiple files records associated with it which results in higher volume of reads + an increase in RAM usage and in CPU utilization,
    What are your thoughts on this?

  4. Hi Dan,

    Thanks for the comment.
    We do know and understand that file fragmentation on an SSD can result in legitimate performance issues – and that some SSDs are less impacted than others. We advocate the use of our SSD optimization pass on a regular basis as part of normal SSD maintenance and recommend the use defragmentation on a case by case basis. The PerfectDisk product does support the ability to defragment an entire SSD, or just a single or batch of specific files as needed.

  5. PerfectDisk 12.5 is the best solution for your ssd! I love the way PD treats my ssd space fragmentation with no additional wear on the nand memory

    What’s about an Hybrid SSD (like “Momentus XT”) ?
    Should I consider it is a traditional disk or a full SSD ?
    How can I manage such a disk with PerfectDisk ?

    Thanks…

  7. Hi Frank,

    Hybrid drives use an SSD for a larger cache than a standard drive would normally have. The cache aspect of the drive should be ignored in the same way you ignore the cache on a standard drive. Obviously, more cache = better, and SSD’s provide a cost effective way to give a standard drive more cache. However, all optimizations are made to the disk, not the cache. So a hybrid drive should be treated like a standard HDD.

    Thanks,

  8. Tervehdys, Hi from Finland

    You said that Your have 10 days trial period!!
    Why You all time pops up licence window!
    That is very agressive and very frustrated unkind. I think that i DONT PAID ANYTHINK PERFECT DISK!!!

  9. All this assumes the use of Windows 8 (with TRIM support), what about users with SSDs under Vista (or XP for that matter)? Can you not add some garbage collection routine in place of the missing TRIM support?

    1. Chris, the video and original article on the blog were actually produced almost a year ago and the SSD Optimize feature was added to PerfectDisk in the June 2011 release of PerfectDisk 12. Windows 8 was not a factor.
