Were did you buy this mystically magical hard drive that can transfer faster than SSD's in raid 0?
yea, you're right, it can't be 600mb/s (probably has to do with windows' caching that repman was talking about), but doesn't matter - the popup closed before it opened - so less than a second, for the internal drive. But 10 seconds for the external usb 3.0 drive.
The thing you are forgetting here is that the files that are once transfered are cached for some time. And if you start a new transfer it just pulls it from the cache but Windows doesn't show the transfer.
Like I said try it with a much larger file and you won't see such speeds.
Standard HDD's have maximum read/write of around 150MB/s.
Or if you want to see actual data, download HDTune and run it for both drives.
You might have saw the second I grabbed 4GB of files (almost 8x larger) but still about 5x faster speed even when including the caching.
Anyway, all I'm saying is, in my experience, transferring lots of files is
much faster -
in my experience - when using internal. And if the caching contributes to the apparent speed, all the better. Another good reason to use internal drive instead of external.
But there is another major reason to not use external, which is the primary reason I want internal drives. Two primary reasons, actually - and neither are related to transfer speeds.
1. PRICE of external vs internal varies considerably. Because for external you are also paying for the enclosure. Multiply that by however many drives I buy.
2. WIRES & SPACE. I want internal so it is just there in my computer, no wires, nothing sitting outside, nothing to knock over and destroy the drive, nothing to take up my floor/desk space, nothing to clutter my office.
The noticeable speed increase my my own personal real-time use, of sata over usb 3.0, is just a bonus reason to use internal rather than external.
p.s. you can argue about benchmark tests and supposed speeds until kingdom come; but that doesn't change what I see happening before my very own eyes, which is that internal sata drives transfer faster than external drives.
