Four Sata or Sdd RAID0?

[knightsilver]

Say once the 450MB/s Sdd's come out, with Sata 6GB/s controllers.
Would I gain any MB over Sata 7200/10,000 RPM Hdd's?

Can anyone tel me what the MB/s are(all RAID):

1. Four, WD Black Sata 7200 RPM's?
2. Four WD V.Raptors 10K RPM's?
3. Four Current Sdd's(250MB/s)?
4. Four Future 450MB/s Sdd's(best guess)?

thanks,
shane c.

Lots of raid 0 scores in there, SSD and standard.

your gains from RAIDing HDDs will be minimal as far as OS use is concerned - RAID0 for HDDs makes minimal difference to real-world usage.

Current disk drives are nowhere near the 300MB/s limit of SATAII transfers, and burst speeds are rarely seen in practice. The new interface will ikely be no different to current gen drives.

the benefit to moving to SSDs is the near-zero access time. I doubt there will be much difference in real-world performance between the current SSDs and the next-gen in terms of OS performance.

High sequential transfer rates is rarely important for disks, although it is the measure most quoted in benchmarks. Access time is (usually) much more important, especially for OS use.

Of the options you listed, the fastest will be the SSDs (both similar for OS, the faster drives for sequential rates (obviously)), then the Velociraptors (low access times), then the Blacks. Benches might say different (4 Blacks may give higher sequential rates than the VRaptors & even the SSDs, but you can bet they will feel slower in actual use).
