Defrag Idea
Hi, i've a ssd on my laptop and i've a little question?
What happen if i do an image of my hard disk on an external traditional hard disk, i mount it with acronis mount utility, i defrag it and after i recovery it on my ssd hd?
Is technically possible or is a bad procedure?
Someone has tried it?
Morgan.
I want to test ssd with normal data distribution and with defragmented data recevered from acronis disk image
Defragmenting a mounted image doesn't seem a good idea to me - it may easy generate a huge incremental file. Moreover, recovering an image may rearrange clusters with data (it does so to fit an image of a larger disk to a smaller one - it may do it for some other reason) . Well, if you want to test it just go on and test. Just check the actual fragmentation of restored SSD before tests.
Morgan,
In addition to dev-anon's comments on the idea of defragmenting the mounted image, it is hard for me to see how you will see any SSD performance difference based on data distribution...
The most important factor of SSD performance that is related to data layout is whether the disk is aligned or not. Another factor is how much non allocated space is left on the disk. Leaving some unallocated space can help the disk controller optimize its functions although SSDs already come with non-visible memory capacity to do that.
Other performance factors include the controller/memory characteristics, in particular how "smart" the disk controller is, but this is completely independent of how the data is actually physically distributed in the SSD memory.
If you want to reset your SSD performance, do an ATA secure-erase (not a typically drive cleansing process), then restore your image.
