Are you sure that you have write Cache enabled on the Raid 0 Virtual Disk, you can only set this in the controller bios or by using Open Manage Server Administrator

<div>
the write cache setting wouldn't make any difference with this I/O load. <br />

I have a PERC6/i controller with 4 300GB 15k SAS HDD in RAID0, however, regardless, the settings defined in the RAID, the performance is really poor; depending of the settings sometimes I can get almost 450MB/s read but only 80MB/s write.<br />

What kind of raid setting should I make to increase the writing performance and keep the same reading average?

How setup a PERC6/i controller

Remote access may refer to the connection to a data-processing system from a remote location, for example through a virtual private network remote desktop software, terminal emulation, or the activation of features of a business telephone system from outside the business's premises.

Remote Access

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. Examples of properties typical of embedded computers when compared with general-purpose ones are low power consumption, small size, rugged operating ranges, and low per-unit cost. Modern embedded systems are often based on microcontrollers; the processor(s) used may be types ranging from general purpose to those specialised in certain class of computations, or even custom designed for the application at hand. A common standard class of dedicated processors is the digital signal processor (DSP).
