![]() Which works, if you’re over-provisioned enough for the write activity. (There’s another scheme that is seen used here too, where SSD firmware is configured to treats a security erase of a sector as a TRIM, too an all-zero write of a sector.)īut ignoring that the operating system can tell an SSD that a sector can be erased is just stupid.Īnd absent either erase-on-delete or other notification such as the all-zero-write inference, the SSD is left to erase as the rewrite arrives and depend on a cache of extra sectors. That OWC scheme is also useful for selling SSD to folks using operating systems that lack TRIM, and some OSes still do. ![]() And the SSD firmware folks came up with a scheme that allowed that, while keeping performance. Look, I get it, third-party TRIM wasn’t available back in Snow Leopard era (that OWC blog article is a nearly decade old), and OWC wanted to sell SSDs. And in our first update to SoftRAID for Windows, we’ve added several TRIM features that keep your drives running faster and longer. ![]() ![]() OWC highly advises against using TRIM on their SSDs.Īnd to quote OWC more recently: TRIM is an important part of keeping your solid-state drives (SSDs) healthy. ![]()
