Fixing random read latency on Zhitai TiPro9000 2TB in Relink
Those flashy transitions started having these annoying micro-stutters, especially when moving in and out of towns. I noticed the disk response time was swinging wildly between 3ms and 18ms. I first tried clearing system temp files to free up space, but that did absolutely nothing for a low-level IO bottleneck. It was a frustrating waste of time until I realized the issue was likely partition misalignment. I used a professional alignment tool and found the starting offset wasn't a standard 4K. I bit the bullet, reformatted the partition, and updated the drivers. In the IO analyzer, I saw 4K random read speeds jump from 650k to 920k IOPS. I almost panicked during the re-partitioning when I accidentally deleted a boot file, and I had to use a recovery disk to get back to a stable state. Now, with temps sitting at 45°C - 51°C, the scene switching is buttery smooth. This kind of deep-level optimization based on actual feel is what actually worked. Confirmed the performance bounce-back via CrystalDiskMark.
