Analysis: The Impact Of Shifting From 512 Byte To 4 KB Sectors
Slowly but surely, hard drives with 4 KB sectors are replacing the "legacy" 512 byte sector size. By January 2011, all drive vendors will have made this transition. Buyers of new PCs are safe, but there are still a few performance pitfalls to note.
Benchmark Results: Throughput And Interface Bandwidth
Throughput is significantly higher on the MK7559GSXP, which is a result of progress in general. The larger 4 KB sectors might have a small impact as well, but the improvements in data density are typically more relevant.
Interface performance is not very important in everyday operation, as drives never reach these speeds to or from the physical medium. However, it shows the peak bandwitdh into and from the drive’s cache memory.
