file transfer

It appears that eSATA varies considerably in values, depending on the units on the left axis (is this my supposed 40Mbps speed?. Otherwise, it is considerably higher that the other two. USB 3.0 is considerably lower than 2.0, but would require installation of a new card on my motherboard.

Considering my situation ( USB 2.0, drive cage capable of 3.0) and intended installation of an internal storage drive, what would you recommend? eSATA seems much faster and more expensive. What about my present motherboard and microprocessor capability of 3.0G???

Please advise. I am still confused.

USB storage is typically pretty slow. You don't mention whether you are copying to a flash drive, or an external HDD.

Flash drives have very poor write performance in most cases, typically 10MB/s or less. If you are writing a single file, it will take less time than writing a lot of small files. I've found that lots of small files makes the amount of time go up considerably.

If you're using a cable to connect your drive, the length of the cable can cause performance slowdowns. Also, connecting to the front USB connectors is often significantly slower than connecting to the back ones, since the cables used internally are often not of very good quality.

What if I go through a usb hub connected to my rear cpu port?

[QUOTE=Mystere;1759311]Yes, an internal drive will be faster than USB in most cases. Typically significantly faster.

USB 2.0's maximum transfer rate is 480 Mbit/s, which in practice is nowhere near that. Internal SATA II will do 3Gbit/s (again, in pracite you won't get that much, but it's still much faster than USB's maximum).

So, you'll typically see at least 6x speed difference between internal and USB.

I'm not sure what you mean by "copy vs. transfer". transfer is a pretty generic term, and is often used to mean copy, or download. Do you mean copy vs. move? If you want to move a file (delete the original after copying) then simply hold down the ctrl+alt keys when you drag and drop. Move is the default when dragging and dropping a file on the same disk, but copy is the default between disks.

Easy data cable? That's typically used between two different computers, not one computer and a drive.[/QUOTE]

I believe Easy Data Cable was suggested to avoid a RAID configuration. I thought this cable might accelerate moving files to my external usb drive.

I have installed an internal SATA storage drive in my CPU. I now wish to move files to my storage drive while simultaneously deleting the file from my HDD.
I have not found a "move" selection on my Win 7 menu. I will continue looking.
