In my proactive attempt to maintain my SSD’s performance and knowing that it degrades as it fills, a user should benefit from keeping a certain calculable amount or percentage of space “free” (Over- or under-provisioning), correct?
To maximize storage, use and performance, what would I need to do to calculate and configure this space?
Info:
SSD Drive: 120 GB Kingston Hyper X Sata III drive. (111.75 Usable).
TRIM is supported and windows recognizes the drive as an SSD utilizing TRIM.
OS: Windows 7 Home Premium 64 bit service pack 1 (20 or so GB, 91 GB remaining)
Various programs and files (40 GB, 41 GB remaining)
With the remaining 41 or so GB, I believe that I will benefit by locking some remaining available amount to maintain the performance of the drive. How can I calculate the amount so I know how much remaining space I can use for files and programs and how much to secure as free?
Edit:
Most of the activity will be reads and average home user writes to the drive, So I am not as concerned about endurance as I am about performance in regards to allocating the space.
+1 for your iunput. There is a note #"4" on the kingston site - " 4. Note: The over provisioning can only be modified at the user’s own risk and will require third party software to partition the drive. Kingston recommends that only experienced and knowledgeable users attempt to customize the over provisioning area. Kingston will not provide support or any additional tools to execute this feature." So, I do not know what 3rd party software is available, it's not on their support site. – Carl B – 2013-02-04T21:37:49.977
Yeah, I don't think it's worth it to look into whatever Kingston is talking about, since just partitioning the drive to 90gb and leaving the rest empty does the exact same thing – Marcus Chan – 2013-02-04T22:29:42.203
By partitioning do you mean to say create an empty partition to take up 20% of the disc rather than attempting to leave 20% as free space? Or then again the same could probably be said of shrinking the main partition to be 80% of the total capacity. So that means the partition has less to do with the performance than the actual total hardware. – MetaGuru – 2013-02-06T20:53:06.390
@ioSamurai I'm not sure exactly what you're saying here. But any method of ensuring the drive controller has ~25% free blocks to work with will be fine, whether that's resizing the data partition or just leaving space free inside the partition. – Marcus Chan – 2013-02-06T23:27:13.313
