Windows 7 format will align it properly. If you want to do your own format with diskpart, use offset=1024.
The above references should guide you well.
One thing to note, this is a sandforce based SSD. It compresses/decompresses the data as it is written/read. The transfer rates quoted by Corsair is based on the ATTO benchmark, which uses zero-filled,100% compressible, data. Real world files are not very compressible. If you run a benchmark like CrystalDiskmark, which uses random data and which is not compressible, the rates you see may be disappointing, especially for writes. However, this is nearer real-world than the ATTO or HDTUNE benchmarks which use zero-filled data.
Make sure your controller driver
is using the Microsoft msahci.sys driver, which supports TRIM. TRIM is very important for maintaining the write performance of your drive. Some MB devices like the Marvel or Jmicron SATA chips may not support TRIM, and only later versions of the INTEL controller driver do.
You should not obsess and run benchmarks all of the time. It will decrease your write performance (especially with random data like crystalbenchmark).
