![]() Just make sure you backup regularly, when they go it can be quick and painful to your data. When they work right, insanely fast.they still have some maturing to go, but they are getting much better. I have been through a couple of SSD's, some worked, others just were bad from the start. Regular spinning HD's (especially the main OS drive.partition) shouldn't exceed 85% or you will run into fragmentation/defragging problems. Typically you don't want to fill your SSD to more than 75% capacity or it will slow down a bit, garbage collection needs a bit of room to work right.that way the nand cell usage can be spread over the whole drive so one part of the drive will not die before another With SSD's it's more or less how much data you turnover (write/delete), not how much you store. Most modern SSD's make good use of TRIM and garbage collection so they won't slow down past a certain point, and never slower than a traditional hdd, even when more or less entirely full. It then writes back the old data + the new data into the pages it needs in the block, leaving the rest marked as "unused." TRIM helps alleviate this by cleaning up blocks/pages/cells into this sorted out state a bit more proactively. What has to happen then is the partial data is read out of all of the existing pages in a block. This is when data needed to be written that is larger than the unused area available in a block. At that point you run into a situation called a read/modify/write. They slow down when every block/page/cell of flash has been written to. SSD's can slow down long before they are completely full. ![]() Pages are arranged into blocks, which are the smallest erasable area available. cells are arranged in pages which are the smallest writable area available. Flash is made up of cells, which store 1-3 bits per cell depending on the type of flash. ![]()
