USB3 for Games?

post #1 of 9
Thread Starter 
So yeah. I had this brilliant idea of buying a USB3 enclosure. Dual bay. Running two 1TB F3's in RAID1.

My question is, would USB3 connectivity suffice for games?

USB 3.0 = 5Gbit/s

SATA 3 = 6Gbit/s

2 SATA 3.0 at Raid 0 = 12Gbit/s

I wouldn't go that way.

I'm using RAID1, not 0:P

But still you are getting less bandwidth than SATA 3. Is there any particular reason why you want to do that?

I guess if you are used to 7200rpm maybe you won't notice the slowness since I have not seen a mechanical drive go anywhere near USB 3.0 speeds.

It should surfice, even tho USB 3.0 speeds are 5Gbps max thoretical i doubt a mech drive would satuate it so the drives should still bench at thier maximum results smile.gif

This. The f3 has an average read speed of about 120-130 MBps with bursts up to 250 or so. Thats about 2 Gbit per second if my conversion is correct.

That's what I was thinking. I have my SSD for boot, but I was *thinking* that because mech drives don't really go that speed, that USB3 would be more than fine. Wanted to make sure though, thus I ask the experts:P

I figured it would be easier this way, having steam on an external that never needed to be changed:P

Doesn't really work that way.

Single 7200RPM HDDs can barely saturate the SATA 1.0 interface. Even if two RAID0 F3 would scale at 100% efficiency they would still wouldn't use up SATA 2.

USB 3.0 still has a bit of maturing to do, but I think you will be fine as long as it's the only device on the USB3.0 controller.

USB3 will be fine. Plenty of bandwidth for games.
