bai bloodlust pila man transfer rate sa imong 2tb na external drive? naa koy 500gb na Samsung na usb3... 50Mbps ra man gihapon....

dapat at least 100Mbps man unta na diba? or dili tanan usb3 external drive paspas?

I made a "non professional" experiment to test my hard disks' transfer rates.
I used a variety of hard disks with different buffer size, transfer rates, and interfaces and a variety of files with different file sizes.

* System Specs:
- CPU: Intel Core i7-930 2.8ghz
- RAM: Patriot Viper 6GB (3x2GB) 1600mhz DDR3
- MOBO: ASUS P6X58D Premium
- OS: Microsoft Windows 7 Ultimate (x64) Build 7600 SP 1

* Hard drives used:
- Western Digital 2TB MyBook Essentials USB 3.0
- Western Digital 640GB Caviar Black 6Gb/s 64MB Cache (SYSTEM)
- Western Digital 1TB Caviar Black 3Gb/s 32MB Cache
- Seagate Barracuda 250GB 3Gb/s 8MB Cache
- Seagate Barracuda 160GB 3Gb/s 8MB Cache

* Power Management Used (Might also affect hard drives' transfer rate)
- High Performance

*Software used for real time file transfer:
-TeraCopy

*Software used for hard disk benchmarking:
- HWiNFO32 Benchmark Feature
- FlashBench (used for benchmarking usb flashdrives, but can also benchmark both internal & external hard drives)

*Files used for transferring:
- Batman Arkham Asylum.iso (Single File, 7.94GB)
- Adobe CS5 Master Collection Folder (1,121 Files, 213 Folders, 13.2GB)
- Lords of Dowtown.avi (Single File, 701MB)

THINGS TO CONSIDER:
*I am NOT a professional benchmark(er?). The softwares I am using may not be that accurate.
*Min/Max Transfer rate is NOT the AVERAGE transfer rate. The average transfer rate may be in between those figures.
*Western Digital 640GB Caviar Black 6Gb/s 64MB Cache is my SYSTEM DRIVE. Some programs (Rainmeter, ObjectDock, Google Chrome, and other System Services) are running from it. They might be affecting the drive's performance.
*I've only run each test ONCE. Certain system condition change from time to time and they might also affect each test's results.
*Some of my drives are 3-6 years old. They might have some bad sectors that may cause their performance.
*I am open to any corrections from the experts here in istorya.net. Ayaw lang ko e criticize or anything for the inconsistencies/inaccuracy of my tests because as I've said, I am not an expert/professional. Instead BE APPRECIATIVE for the time I've spent for this experiment.
