comment What is more important for portable external HDD, interface or rotational speed?
@Hennes: I just copied some files from my 7-year-old external IDE HDD 7200rpm, 160GB with USB 2.0 under my Ubuntu 12.04 to my 2~3-year-old Lenovo T400, and the speed is 8.3 MB/sec. How is it possibly so slow, compared to your "max 43MB/sec"?

comment What is more important for portable external HDD, interface or rotational speed?
@Hennes: Thanks! As to firewire, you said "Usually somewhat faster than USB2. Has some nice advantages over USB when streaming multimedia files, but for HDD access these are not important." I wonder why "for HDD access these are not important"?

@MSalters: " Making a backup is another case where rotation speed is fairly irrelevant." Is it because it is sequential reading and writing?

Thanks! (1) What do you mean by "protocol overhead" for USB 2.0 and 3.0? (2) For firewire, why is it "for HDD access these are not important"?

comment Portability of external HDD, especially NAS and RAID
Does interface of RAID with outside have the same types as HDD, such as SATA, IDE, or as external HDD, such as USB, firewire, or eSATA?

Thanks! I wonder what "UPS" means? I know it is not meant to be the delivery company.

comment Which external HDD is better, pre-assembled or self-assembled?
Thanks! For those preassembled, (1) I wonder how possible and difficult it is to "get a pre-assembled external drive enclosure apart"? (2) If it is the HDD or the enclosure that goes wrong, is it possible to find new ones to replace the HDD or the enclosure (not necessarily identical to the original)?

comment Which external HDD is better, pre-assembled or self-assembled?
Thanks! I wonder which one is more portable (i.e. smaller and lighter), external HDD resulting from self assembling separate HDD and enclosure, and external HDD resulting from pre-assembling?

comment What is needed to convert a laptop hard disk into a removable USB hard drive?
Thanks! It was 3.5". A new question. In the last two pictures, (1) what are the four lines (red, black, black, yellow) from the enclosure and the corresponding slot on the HDD for? (2) What are the black wider and thin band from the enclosure and the corresponding slot on the HDD for?

comment Choosing protocol between my Lenovo T400 laptop and portable external HDD
@Dennis: I think I asked more about matching problem than shopping recommendation.

comment Choosing protocol between my Lenovo T400 laptop and portable external HDD
Thanks! (1) Is it possible to install something like USB 3.0 driver on my Ubuntu 12.04 on my T400 in order to use that portable HDD with USB 3.0? (2) I wonder what kind of portable external HDD you would recommend me to buy, in terms of protocols?

Thanks! By "the USB to SATA converter", do you mean writing from a computer to an external SATA HDD through USB connection between them?

Also are there enclosures that can be used with both IDE and SATA?

Thanks! In your edit, the first link is for 3.5" Enclosures for IDE. I wonder if my laptop hard disk is 3.5" or 2.5"? If 2.5", why not use 2.5" enclosure for IDE?

Thanks! Do you mean the usb cable of the product in your link provides both power and data, so there is not another power cord for the closure?
