Is a USB3.0 SSD Fast enough to use as OS Drive/Boot drive?

post #1 of 6
Thread Starter 
Thinking about replacing my SSD's with a USB3.0 and using it to boot from, but also keep it external so i can take it to other places on the go. Is this feasible or does using usb3.0 instead of sata2/3 make it go significantly slower? Thanks.

if what your planning is to run an OS then yes, its perfectly fine just so long as the computer your running the SSD + USB 3.0 config through a USB 3.0 slot then there should be no problem as I did it before I had all the components for my computer, I wanted to get all the programs installed prior to and it worked fine for me.

I would run some random performance benchmarks..... USB3.0 has more overhead that SATA.

May seem a little extreme, but watch the temperatures of the USB port (if you can), if you're running an OS on it, data will be accessed constantly, thus increasing temperatures.

Sometimes, when my USB ports aren't even being used, they're at 44C. And there has been many reports of USB ports catching fire, haha. I know it's extreme, but still, keep a look out tongue.gif.

I ran Windows 7 through my USB 3.0 1TB External HDD in my old computer, and it was running really hot, around 65-75C sometimes.

It would probably run faster than a mechanical HDD to be honest, just don't do large loads at once, or data transfers whilst playing games n' stuff, and you should be fine!

I think your SSD will be bottlenecked, although it is USB 3.0. Run benchmarks first and compare speeds throught SATA and USB ports.

What are you talking about?

1) It is a SSD so power draw will be less than 4w.
2) What reports of USB ports catching fire? USB 2.0 only provides 2.5w while USB 3.0 provides 3.6w. The plug and wire are robust enough as well.
3) USB ports do not have temperature sensors.
4) Not all SSDs have temperatures sensors.
