SSD performance tips for Intel chipsets and RAID-0

We had a chat with the Kingston labs team this week in California and noted down some free performance improvements, and limitations, you should be aware of if you own one or more SSDs:
  • The Intel SATA ICH9R/10R/P55 controller under RAID-0 has a maximum real world performance capacity of about 600MB/s in total between it and the CPU.

    Despite the fact you'll need several (four+) SSDs to hit this limit at the moment, it's worth bearing in mind that to get ludicrous performance you'll need at least a PCI-Express x8 card.

    Until Intel increases its DMI and/or SATA controller bandwidth, this could prove a more regular limiting issue when future SATA 6Gbps parts arrive.
