Various RAID levels and speed results

[Ice Czar]

the SX4060 is a 32-Bit/33 or 66 MHz PCI 2.2 interface as is the original SX4000
the SX4030 is a 32-Bit/33MHz PCI 2.2 interface as is the SX4000 Lite

the original SX4000 supports 256MB of SDRAM
the SX6040 supports 64MB of ECC SDRAM

ok so is your point that the promise controllers are good? Those benchmarks seemed to be pretty good for the promise controller.

Is the only difference between the SX4000 and the SX4060 that the SX4060 comes with 64MB of ECC RAM, while the SX4000 doesn't come with any RAM, but requires you to buy at least 64MB ?

Is there any reason to buy the SX4060 instead of the SX4000? I have no problem buying a stick of RAM...I might even get more than 64MB.

Although ECC RAM isn't required, is it a "good idea" because it's dealing with data, or is it not neccessary? It's a lot more money.

Oh man here come the questions...Even now I'm still debating over RAID 10 and RAID 5. I already have four 160GB drives so that's not an issue. I really just want the fastest speeds. The difference between 300GB and 450GB doesn't matter to me.

I'm telling you, don't skimp out like you did with the highpoint (your going to end up with another return), drop the ends and get the 3ware. Many of those benchmarks on that Dutch site are not really relative to what your going to be doing. The only stat that you need to know is throughput, and your going to get better write/reed speeds with the 3ware along with a more polished feature set. Lets not forget the XOR proc helps a lot if the raid arary is going to be your main computer, because your system can get held down big time when transferring files with the promise.
