Well, the maximum speed for USB 2.0 is 60megabytes a second.
SATA 2 is about 375 megabytes per second.
How do these speeds translate to hard drive speeds such as 7200 or 10000RPM? What about SSD drives?
I have a USB 2.0 Maxtor 3200 7200RPM drive. I have never seen the write speed (copying files) ever go above 30 megabytes a second with it. Most of the time it does 15-22. I have an Intel Core 2 Duo E6600 overclocked to 3GHz, 2 GB XMS2 DDR2 800 Corsair Ram running ar whatever bus speed the processor needs to get that fast and an asus p5b deluxe wifi-ap edition.
Is the drive being limited by the USB connection for would it go the same speed if it were hooked up to SATA? I have never tested the read and write times for my Seagate 7200.10 250GB hard drive (3 gigabit SATA I think) so I can't compare. Really though, are there really any drives that can push SATA or USB 2.0 to the limit? Are the hard drives I use my bottleneck on my PC (I use it for commercial games and have an nVidia 8800GT 512MB and a Soundblaster Audigy 4 PCI card).
Would it even matter if I got an eSATA external drive or would it be about the same speed as the USB 2.0 (I know the eSATA is capable of more than USB 2.0 but I don't know where I would find some good places to read about whether the actual drives are capable of that speed).
Also, I hear SSDs are infinitely faster on read times than traditional hard drives but slightly slower on write times. For anybody that uses SSD drives is it worth the write speed tradeoff? Will that get better?
