This log is being written on a RAID 0 hard drive which includes 2 Western Digital Caviars (7200 8mb cache 80g SATA) hard disk drives. It was recommended that the same brand and style were used when setting up any multiple disk arrays.
Hardware and Prices
· 2xWestern Digital Caviars 7200 8mb cache 80g SATA HDD ($45 each)
· 1x Maxtor 6y250p0 7200 8mb cache 250g IDE HDD ($79 today, $175 4 years ago)
· 1 Floppy Disk Drive ($5)
· 1 Floppy Disk ($1)
SATA hard drives are very easy to install on newer motherboards like the XFX 680i, because the ports are smaller and more exposed. Thus, there was no problem installing the 2 Western Digital Caviars. The IDE and FDD ports were less exposed and were blocked by numerous wires. Because of that, a removal of the motherboard and adjustment to numerous components were made. This process took an hour. Ensure a solid power supply to run a multiple HDD array. A 350 watt PSU is recommended. For this setup, a 600 watt PSU was used.
To set up a any RAID, reformatting is unavoidable. Backing up data is for convenience purposes, but it can also exercise organization skills. All backup data was written to the Maxtor 250g HDD. Games like Counter-Strike Source, Unreal Tournament 3, and Hellgate London, and applications like Photoshop CS3, Office 2007, and Vegas were able to be backed up. Personal projects, movies, and text files were also data that was transferred.
Vista and new OS's will not need to use a floppy disk to retrieve RAID drives, but this process was done with Windows XP Professional (64-bit.) The CD that came with the motherboard will usually have an audio driver, chipset driver, and RAID driver. XFX 680i's CD gives us option to write the RAID 0 drivers onto a 3.5 1.4mb floppy. Make sure that the files that were transferred onto the floppy are not corrupt. Create a second or third disk of RAID drivers if you have no way to counter corrupt files.
After the hardware and software have been prepared, it was time to go into BIOS and set up the HDD Array. Access the BIOS by pressing DEL before the operating system boots. I tend to spam DEL for 10 seconds until the BIOS pops up. On any BIOS, enable RAID on the 2 ports that are connected to the 2 HDD's. RAID 0/Striped was preferred in this situation. After doing that, change boot priority to CD to install your OS. When installing the XP pro, press F6 for the first seconds of the installation. This will allow drivers that were transferred to the floppy to be detected.
If no blue screen of death was visible during or after installation, congratulations. The RAID array is now operational. Though it will take about a day or two to get the computer back to its former software state, know that it will be somewhat quicker than it would be on 1 HDD. Depending on how much data was backed up, it can take a long or short time, but let's talk about results.
The aftermath is overrated for a gamer. Even though every second counts, the only thing noticed is a 2% speed increase in load time. For a media designer, transfer rates are noticeable with a speed increase of at around 10% for higher volumes. Writing files has been atrocious. There is a 5% chance that a sector could not be found when installing files. This means that the RAID confused itself when trying to write onto 2 HDDs at once. The RAID 0 experiment was a success, but the performance increase is uninspiring.
Right now, there are 7200 and 10000 SATA hard disk drives. The higher the RPM goes, the faster access time will be. 10k RPM are usually more expensive than the 7.2k, but the results are worth it for a gamer. There is a 15000 RPM hard drive, but it requires an SCSI card, which is usually not found in the common motherboard. Yes, the price is also higher- about 2 times more than as 10k. The higher the RPM, the louder it will be as well. Most reviews show a 150% decibel increase with 10k, and a 300% decibel increase with a 15k, compared to a 7.2k. This allowed me to find out something about new HD tech, because eventually HDD's will be so loud that people will want to convert to slower speeds. Solid state drives don't make any sound and are 4 times faster than a hard disk drive. Right now, the tech and speed premium will cost 30 times more than your average 7.2k. Yes time will tell if SSD will be the future of hard drives, but for now save your money.
Like L2 cache on processors, regular cache on an HD is accessed faster. Because of this, having a 16mb cache is better than having an 8mb cache. Think of cache as a waiting room. I'd rather have 16 people waiting than 8 people waiting for the next ride. Looking at charts there is a speed increase, but not significant enough be desirable. There are 32 mb cache HD's, but still too superior for economy pricing.
Right now, I am somewhat satisfied of my HD position. The only thing I would change would be upgrading to 16mb cache, but it won't improve much. I care too much about acoustics to get anything louder, so I plan to wait on SSD tech to come to the economy. So, this ends the RAID 0 experiment; bittersweet.
