I'm working on a new video formy YouTube channelthat will go into some more detail on which of the drives I tested support TRIM, but while I was researching for that video, I also found that TRIM support in Linux is not as simple as it seems at first glance—it's definitely not p...
Before we start implementing the various tweaks, we need to make sure our SATA controller is in AHCI mode and that the TRIM command is enabled in Windows 7. You want AHCI turned on because it is the specification by which Native Command Queuing (a SATA-specific technology) is enabled. SSD...
For testing, we’ll have to create a small file on the affected SSD partition, as we’ll be deletingitto see if TRIM in fact worked. After opening up a command-line, enter su or sudo mode (the latter using ‘ sudo -s ‘). Then, create a small file: techgage Desktop # seq 1 1...
For those unaware, TRIM is an ATA command that solid-state drives can take advantage of in order to prolong its fast performance as time passes on. SSDs thatdon’tsupport TRIM have an inherent fault of slowing down over long periods of time (months, or years depending on the level of u...
(HDDs). However, the performance of the SSDs can be degraded depending on the I/O access pattern due to the unique characteristics of SSDs. For example, random I/O operation degrades the SSD performance since it reduces the spatial locality and induces garbage collection (GC) overhead. In...
