I do not know why I have a higher read speed with my Samsung hard drive, maybe it's because of the SATA controller ?

I do not know why I have a higher read speed with my Samsung hard drive, maybe it’s because of the SATA controller ?

My Seagate drive tested under HDTach only produces an average read speed of 68.6 MB/s. It's an ST3320620AS 3 AAE model (320GB, SATA 3.0). I have a higher burst speed than than the Samsung (258.1 MB/s and and a faster random access (13.3ms). AS for the SSD drive, why are these so much slower on writes?

Windows uses 4k sectors for formatting NTFS and the same figure is used internally for memory paging. Interestingly you can format a drive using 512k sized sectors with disk management, this brings noticeable I/O improvements but in my experience causes problems with certain drivers rendering any sector size above 4k on system/application drives unusable, shame! My guess is that 4k is the best trade-off size for paging X86 ASM instruction, anyone confirm this? Looking back on this i'm wondering if my rambling bears any relevance to the article anymore lol, oh well i've done it now, it stays :P Not to be confused with the 4k vs 512 figures above but…
