On 2 of my computers that windows 7 did installs on the AS SSD benchmark states
M4-124 in a i7-930 pc
The System Reserved or boot have normal offset of 1024k-ok and msahci-ok.
The system partitions states 258048-ok and msahci-ok.
830-in a 3770k
The boot part partitions have normal offset of 1024k-ok iaStorA-ok.
The system partitions states 103424k-ok.

When I run fsutil fsinfo ntfsinfo ?: on both partitions I get the below.
Bytes Per Sector : 512
Bytes Per Physical Sector : 512
Bytes Per Cluster : 4096 would this mean the offset is correct ?
Bytes Per FileRecord Segment : 1024
My speed is faster then stated on all ssd.
Are my offsets correct
Should win7 use a System Reserved or boot partition on a ssd.

ntfsinfo will not tell you, but sectorInfo will. If you have the latest windows updates try fsutil fsinfo sectorInfo. Yes, Win7 by default reserves 100MB as a system/emergency partition during a standard clean install.

Correcton: sectorInfo seems to work on Win8. I would try START:RUN:msinfo32. Dig down to Components : Storage : Disks. Divide 'Partition Starting Offset' by 4096. If there's no remainder, you're good.

System info states the partition starting offset = 1,048,576 which is normal
