I assume that OWC assesses that Durawrite is better than TRIM and makes TRIM obsolete. Sandforce has a patented technology called Durawrite. TRIM does not generally work behind a RAID environment.Lower write amplification – Less data rewritten and more free space is available ► Improved endurance – Reduced writes to the flash ► Higher throughput – Faster host write speeds because less time writing for GC ► Increases the free space known to the SSD controller The SSD marks the indicated locations as invalid data The OS sends a TRIM command at the point of file deletion When the OS writes a new file to the drive, it will eventually write to the previously used spaces in the tableĪn SSD only knows data is no longer needed when the OS tells it to write to an address that already contains data When the OS deletes a file, it marks the file’s space in its logical table as free – It does not tell the drive anything SSDs do not understand the file structure of an OS they only track valid data locations reported by the OS The OS tracks what files are present and what logical blocks are holding the files Invalid (replaced) data is ignored and gets erased ![]() Valid data is consolidated and written into new blocks GC starts after each page has been written one time Cisdem ContactsMate is a great contacts manager that helps you easily sync contacts from Google, Outlook, iCloud, Exchange, Facebook, Twitter, LinkedIn. One full block of pages has to be erased, not just one page NAND flash cannot directly overwrite a page with data it has to be first erased In flash memory, Garbage Collection (GC) is the process of relocating existing data, deleting stale data, and creating empty blocks for new dataĪll SSDs have some form of GC – it is not an optional feature I contacted Sandforce regarding to Trim or not to Trim – They gave me good insight into their process:įirst – they are separate and not to be considered the same! He does make some valid points but I am no expert with regards to this subject and will follow the ssd manufacturers advice (OWC). Oddly, I was over reading some comments at OWC and found this post from here ( )
