RIVE Hardrive Issue RAID 0 SSD

Hi everyone, I have had this issue for about a year and decided to look for help.

Basically when I am transferring files to my WD30EZRX 3TB hardrive I get huge speeds then it declines to 1MB/s. Is this normal?

My setup:
2x RAID 0: OCZ Vertex 450 Series VTX450-25SAT3-256G 2.5" 256GB SATA III MLC Internal Solid State Drive (SSD)
1x WD30EZRX

SSD are connected to Intel SATA 6, and the WD drive is on the SATA 3 port.

I seemed to have helped it some by replacing the SATA cable. I suppose I should go to Western Digital to get some answers.

Here is a graph showing what I mean, there are bursts of speed but many valleys where I am getting 6-9MB/s. Before the new cable is was getting stuck at 1MB/s.

File transfers to NTFS are cached. This creates the illusion of high-speed as the information is actually written to RAM (waiting/cached to be written to the hard drive at a slower speed limited by the hard drive). It is very possible that the slowdown occurs when the PC's capacity is fully used and the apparent speed drops to the actual hard drive write rate.
That might be the situation in your case, even though the chart does show very dramatic changes. If I am correct, smaller transfers might occur much faster.

Hey thanks for the reply Snakeyes,

I'm new to the whole overclocking thing and was planning on getting a watercooler soon. That radiator you got looks pretty sweet. If you get time could you send me the OC info you use? I also have problems with my RAM I think where after about 24hrs uptime I start getting all kinds of visual anomalies and random Overclocking failed bootups. I put the voltage up on the RAM and that helped it stay up longer. I also noticed my RAM is specified as dual channel, but when I purchased from newegg the description was a quad channel kit. Wondering if anyone could explain if I got the wrong RAM or something?

Quad channel refers to the four sticks. What you have is a dual channel. You got very expensive and very good RAM. Just run it based on XMP and all should be fine. Overclocking beyond that will not give you any appreciable results. Also four sticks and 32 GB will put a strain on your system and further complicate overclocking your system and your ram.


As far as overclock settings, believe me on this, every system even with identical components is very different and transferring overclock settings will rarely, if ever, work. They are some very good "stickies" on this forum that help you work your way through overclock slowly steadily and safely. Start there and then post as you progress and I will be glad to assist you through the steps as you experience them. Also keep in mind, that different processors have very different overclock characteristics. I was lucky to get one that can run torture tests overnight at 4800 MHz with no issues. There are many identical processors that are lucky to be able to reach 4000 MHz and remain stable.


Best of luck and be patient, you have a very nice system. Build it slowly and enjoy it while you learn about it. Don't bother trying to overclock the ram beyond its specs. It has minimal real-world benefits when you do that.

I see, but am still confused as to why Corsair would list the 4 stick memory kit as a dual channel kit and Newegg calls it quad channel. I guess I am not the only one hah.

Edit: I went to look and Corsair does call it a quad channel ok I am dumb.
