Do USB3.0 single drive enclosures give out at ~200Mb/sec reads?

On the enclosures I've tried I don't seem to be able to get much faster regardless of the speed of the SSD. I do note some RAID enclosures can hit higher speeds so I'm wondering if RAID (or indeed Thunderbolt) is the only way to get higher throughput - and even then, if it's actually worth doing that (i.e. what kind of improvement will I get, and I really only need 500Gbish storage in this usage anyway).

 

The thread topic don't match what you asking in the post xD.

Re the question, you get higher transfer speed? Isn't it wonderful ?

I mean if you need a external for real time work, or you cant stand that progress bar go slow, then it is a improvement xD.

MORE the BETTER!!

 

Thunderbolt is a pain in the butt in many ways (I do actually have several Pegasus R's and WD TB Duos, many of which run SSDs - but this is for work use. I don't exactly need that to run e.g. a Steam library on an external drive). I'm just wondering if there is some sort of single drive limitation which the USB3 bandwidth can't overcome.

 

It would appear you have a bottleneck somewhere in the chain? A similar situation was experience with purchasers of the Canon 5D Mk III when the inferior controller would limit speeds on the SD card slot regardless of the speed of the card. Strangely, no such limitation was seen on its neighboring CF card slot.

 

I'm not so sure about that in terms of the USB controller on the host - the speeds have been fairly consistent on my previous DIY, an HP Z and also a 27-inch iCrap.

Perhaps there are slower USB-SATA bridges? These enclosures I've bought haven't been the cheapest ones but well, it's actually kind of hard to buy an expensive single drive enclosure. I was wondering if anyone had recommendations for fast enclosures (if there was variance in the field) among other things.

 

^ This.

A lot of USB 3.0 drive enclosures use SATA-to-USB controllers that don't operate at full USB 3.0 speeds. Therefore, you're likely to see max throughput of around 120MBps - 130MBps, even though both USB 3.0 and the underlying SSD drive are capable of much higher speeds.

 

i get 170MBps on my thumb drive so i am sure it can. USB 3.0 should be able to hit 500MBps

i would assume the enclosure is the issue personally.

 

You just need a better enclosure. Here are some examples with benchmarks. http://www.techpowerup.com/reviews/Rosewill/RDEE-12002/4.html http://www.tweaktown.com/reviews/5241/caldigit-av-pro-usb-3-0-hdd-ssd-enclosure-review/index.html

 

As I said I'm typically getting 200-220MBps. Could I go higher?

 

USB 3.0 Port with UASP,

don't ask me what it is and what have it. some kind of asus desktop board?


200ish is maxed out on normal usb3.0 afaik.

 

OK. Well, I guess I'll have to use Thunderbolt/ eSATA if I want to go any faster externally. I probably won't bother for this use - what I might do is have a look around at if I can get my hands on any older high capacity SSD's which are less of a 'waste' to use in the enclosure.

 

About 220MBps is about the highest I have seen so far.

 

Pretty much, I've tested a couple of 2.5" enclosures and they all topped out at SATA II ish speeds.

 

I got just a small amount better than that here but its not under ideal conditions.

So apparently some do. I've ordered one of those which is supposed to get higher speeds (Newertech Voyager S3), but it's now not a big priority since I've shuffled all major external storage off to Thunderbolt or taken it internal.

 

Got a friend that maxes 300Mb/s+ on his USB 3.0, some kind of modified motherboard he's got. I remember his transfering all of his 'legal' movies to me. Took him a few minutes and I got several hundreds of gigs lol

 

Asus boards. At least new ones I'm given to understand. Actually I should try it again on my Z87-Deluxe/Dual.
