Windows 7: USB 3.0 vs 2.0

Speaking from experience, when I moved from my Seagate 7200.12 1TB drive to my Western Digital Caviar Black 1TB...I saw no noticeable difference based on the dual processors on the Caviar Black. And testing the 2 devices shows a slight edge to my Seagate drive over my WD. I had put the Seagate drive into another machine at my house and went with the WD for the performance.

As far as this conversation goes....there really should not be any tangible performance difference running on the 6.0Gbps SATA port. A 3.0Gbps SATA port is more than adequate to handle the data throughput from these hard drives without maxing out. In fact, at max speed on a mechanical drive, it rarely exceeds 50% of the available bandwidth that 3.0Gbps can handle.

I could measure a difference when I moved from the WD Blues .. to the Blacks .. (with the twice sized cache) ..

Not that I could detect any difference in the way my computer run...
But the 5 yr warranty and the extra space did make me feel better

My main computer won't take the card.
Yeah, that'd be good to know
I did not expect these numbers
Left to right ... Comparing a ...
WD SATA2 320GB 16Mb Cache ...
WD SATA2 640GB 32Mb Cache ...
WD SATA3 640GB 64Mb Cache ...
all plugged into a SATA2 Mobo .. running WXP
When I get a chance .. I'll see what W7 gives me.

Looks like I'll have to get a SATA3 card and do this again.

My order has been canceled because they couldn't provide what I wanted and I didn't want the alternative. I have however just ordered the ASUS PCI-E USB 3.0/SATA III card. Now I just need something to plug into it. I'm thinking of a WD My Book 3.0. I'm a bit hesitant tho because it's not something I really need and maybe I'm better off using the money towards another SSD. I hate having to make these decisions

The last one messed up my computer with it's software.

I'd rather build my own so I can get to the HDD in case of trouble ..
or use the enclosure to read a Hard Drive.

I doubt that the "My Book" has a SATA 3 HDD in it.
The warranty is 3 years ... I can build my own with a SATA 3 HDD at 5 years

Yeah..I've decided against it. I'm looking at a new Crucial SATA 6Gb/s SSD.

I'm thinking it's premature to worry about jumping to SATA 3 USB 3 right now.
Ive avoided getting excited about SSDs due to the write problems.

I'll just wait a little longer to Boot or have Photoshop load.

Out of curiosity, what write problems are you referring to? The limited # of writes would be my assumption...but I think it's been pretty well determined that heavily used drives will last a good 10 years. I'll be honest, I doubt I'll still be using this 80GB SSD 10 years from now.

Something ??? .. about the way a SSD arranges the Writes to avoid writing too much to a specific place.
And this results in a slowdown in the performance of the SSD over time.
Sounds like it might be a maintenance headache.

This issue is resolved with a feature called TRIM. As long as your drive supports it(mine does) and as long as you have Windows 7 (Trim is native), then this is a problem of the past. No maintenance issues at all for me. Many of us here clearly have Windows 7 and there are many drives with Trim support and many have firmware updates which allow Trim to work.
