I used only the 3gb ICH10 ports, not the two white ICH10 6gb ports. While the ICH10 and the Marvell can do 6gb SATA, this is a 3gb drive. The motherboard has two SATA interfaces, an Intel ICH10 along with a Marvell 9128. With 16gb of RAM and an i7 2600k processor, running at standard 3.4ghz speed. This is plugged into an Asus P8P67 motherboard. I've got an Areca 1210 PCIe RAID controller. Here they're just a test to compare performance between different interfaces. They're just some drives I'll be using in another desktop machine. I've got a pair of new Samsung F3 1TB drives. I ran a few tests through crystaldisk mark. But modern Windows manages to buffer and cache properly, so the HDD will switch more slowly from reading to writing and vice versa clustering its reads and writes as it were. HDDs are not parallel devices they can only do one thing at a time. So if you get 10MB/s that means 10MB/s reading and 10MB/s writing at the same time much more difficult than just reading or writing. You would need at least 10 HDDs to achieve that kind of throughput, and only if you write large files.įurthermore, copying from one partition on the RAID to another partition on the RAID means the RAID array has to do both reads and writes. So if your scores start with 1GB/s then that doesn't mean the HDDs are processing that much they can't and the SATA cable cannot either not even for 2 disks in RAID0.

So the first 1 gigabyte you basically got for free in less than 0.1sec after that you are hitting the real physical write speed. You can see 0.6MB/s is the max for reading 4 kilobyte files.Īlso, if your speed begins with 1GB/s than that means your OS is buffering writing to RAM first. Speeds will drop the lower the file size, basically. HDDs are much slower when processing smaller files, since they have to seek.

Remaining partition of the drives above, well now I know why I was having speed issues from this server now.
