Why don't usb to ide/sata adapters exist?

Recommended Posts

You can convert sd/microsd to ide or sata, why not a usb stick? It's faster and if you want to transfer files, just plug in, instead of having to use a card reader.

They do exist, but something tells me you have some weird ass-backwards "you're doing it wrong" use case

They do exist.
They exist in the bare cable form, where you can attach an external drive to a USB port (such as when you are recovering files from a failed laptop)
https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=sata+to+USB

They also exist in the hard drive enclosure form. There are laptop drive size (2.5") and desktop drive size (3.5") enclosures

I'm using an enclosure to provide extra storage to go with my Xbox Ones' lame onboard 500GB.

*edit*
I know I only covered USB -> SATA, but USB -> IDE does exist as well
I just found this:

You are on your own to provide power though (molex).

Nope, I'm after the other way round. Install operating system on a usb stick which somehow plugs into an ide or sata port internally on the motherboard. Don't particularly need one, just surprised they don't exist.

You can do that, it's called a Live CD (and you can format a usb stick to behave as a CD with e.g. Rufus), and plugging a usb stick into the rear panel IS plugging directly into your motherboard. Since your motherboard is interfaced directly with either a SATA or IDE drive, your job is done.

So, there's nothing like the adapters for ide/sata hard drives on usb, but in reverse? I want it to specifically plug into either of those drive interfaces. I just don't understand why they exist for sd/microsd cards, but not for usb.

Because USB has slower read/write rates than SD. E.g. if you connect an SD to an SATA port, you could theoretically have as fast read/write reads that SATA supports, however if you stick a USB stick onto an SATA port, you're limited by USB.

Therefore you don't really gain any benefit from plugging a USB stick into a SATA/IDE port, beside that you could stick it inside the PC.

Though with USB 3.0 the speed issue isn't such a big factor, I guess it's just a thing that not many people want to do and so you'd have to create your own adapter.

I've also heard that at least with CF adapters, they're pin-compatible with ide. Obviously not something that would run as fast in a usb form.

I dont understand what you are after, if you could be more specific with what you are trying to accomplish?

Why would you need such an adapter when you can boot directly from a USB flash drive on any computer made in (over) the last decade?

Well, there's adapters for even stupider things, like isa to usb... no o.s made in the last 10 years is going to support an isa card, adapter or not.

boot from one of those, have access to your harddrives... no adapters needed. I still really don't understand WTF you are on about though, and I have and use SD -> USB and IDE/SATA -> USB adapters. You don't need a USB -> IDE/SATA adapter because it's called "Your Motherboard"

Though as everyone in this thread has asked: Why u do dis?


I don't remember there being a 20 pin IDE cable for anything. All I remember is 40/80 pin PATA and 34 pin Floppy

This is likely to just allow you to attach 2 USB 3.0 ports from a motherboard to a remote place in the case with a IDE cable, not as a conversion from PATA to USB.

Oops, that is definitely 20-pin IDE. Yeah that won't really solve what he's looking for.

I doubt if a "dumb" PATA -> USB exists. PATA is a parallel interface and USB is serial. Any such cable would need some sort of micro controller in the middle.

20 pin IDC, if we're going to be pedantic. They appear to have become the standard header connector for USB3.

Does anyone know if this can be done.

Reason is the following. Gigabyte boards are notorious for not being able to boot from USB, although some have had success in different ways, many more have given up.

I have external SATA ports mounted on a slot panel which came with the mobo, so that external SATA drives can be plugged in.

Given that the USB is useless except for storage, I too was wondering if anyone did USB to sata.

 

Just so we are on the same page, convention usually dictates that you write the direction as from and to, input then output. Whereas many people don't have a clue and think they can write it either way around to mean the same thing. 

If I wanted to go from a SATA to a USB (as in an external USB drive) then you would write SATA to USB, not USB (which is the input) to SATA ( which is the output).
