my desk is on the other side of this wall so this balcony oversees the warehouse operations here at NC anyway I recently uploaded a video to my other channel where we took the cameraman's computer and we upgraded it with an SSD featuring trim and Windows 7 so I got a few messages asking me what exactly is trim and why did you emphasize so many times that that was important and that it was a key feature of Windows 7 well first of all Windows 7 is the only operating system right now that does feature trim support so there put that in your pipe and smoke it that's why it's important but that doesn't actually answer the question the question is what does trim do so here's what trim does I devised this um example trim is kind of like the insert key because normally with any SSD drive the performance is actually going to degrade as soon as you take that fresh never written flash memory and write over it once every time you try to write it's like this so even after you delete a file in clear space if you want to rewrite that H you actually have to delete it first which takes up one cycle and then you have to write to it after so it takes a lot longer what trim does is it's a way of the operating system telling your drive whenever you delete a file immediately hey that bit isn't there anymore so you can just write right over that so it clears it out right away so it's kind of like the insert key if I press the insert key and you know I want to write something over this well it helps if I type correctly then what it does is it enables you to write data without first removing it and it really increases the speed and the performance of your SSD especially over time now there are other Solutions like garbage collection but trim really is the most elegant solution because all you do is pop it into your system and forget about it keeps your SSD running in tiptop shape"}
