Please log in for more thread options protector was bad because my external USB 2.0 IDE drive is TOAST and will no longer show up in my computer (I took it out of the enclosure and installed it internally and it wouldn't show up either). SO, today I went to Fry's to get a new external drive, but decided to just get an internal SATAII drive because it was cheaper. I got a 320GB Maxtor SATAII for $59.99. So my MOBO supports SATA (I'm assuming SATAII also?) and I figured if I end up wanting to make it an external drive down the road, I will just buy an enclosure on Ebay. So my question is: Is there a speed difference when using an internal hard drive vs. an external hard drive? Common sense would tell me even though it is a SATAII drive, if I make it external and I connect it via USB 2.0 (or firewire for that matter), that now it really doesn't MATTER that it's SATAII, because now I'm only transferring files at a USB 2.0 speed, correct? So am I correct in saying that if I want fast transfer speeds, I am better off leaving it internal inside the computer via SATA then making it external for convenience purposes correct? And if I DO want to end up getting an external drive for convenience purposes that I can theoretically just get a cheap old IDE drive because its transferring at USB 2.0 speeds so it really doesn't matter if its SATA or not right?

Please log in for more thread options No there is no reason to assume SATA 300 also. IF your board is new enough that it does support SATA 300, then you have that support... but if it doesn't support SATA 300, you might just need to change a jumper on the drive to run it in SATA 150 mode. Above I used "150" and 300" since SATA I and II are not proper terms. >and I figured if I end up wanting to make it an external drive

Right, USB2 is substantially slower than SATA150 or 300. You'd be as well off buying a controller card that supports eSATA and connecting the drive to it, putting it in that enclosure you already had to contain it (so long as you don't need to use it as USB elsewhere). >So am I correct in saying that if I want fast

Not exactly, you can say an IDE drive is just as fast in your system because SATA is not a performance level in itself, it is an upper limit that a single drive (that you have) cannot reach yet. It is no more or less valid to choose PATA (which you called IDE) over SATA, or vice-versa, for any kind of performance factor reasoning at all, inside or outside of an enclosure, rather than considering the performance of the exact drive via it's physical parameters besides which interface (PATA or SATA) it uses. Beyond that, yes you could use PATA, but it has nothing to do with performance differences between the two. Rather it would depend on what your external enclosure supported. Today there are fairly good deals on enclosures with drives in them so you might just keep an eye out for deals on thos, especially since some of the aftermarket enclosures are pretty poor quality (including the PSU in them or their external brick) which could be why your prior enclosure and drive failed). | ||||||||||||||||

Sometimes a surge will phark the surge protection circuit and thus, it will no longer protect you from a surge. I checked on of my pcs lately and both surge protectors had the surge protection light OFF. So I replaced both of them. -- http://www.bootdisk.com/ | ||||||||||||||||

Is it beneficial, harmful, or neutral to the fundamental purpose of such a unit? -- <http://www.cs.auckland.ac.nz/~pgut001/pubs/vista_cost.txt>
