How fast is your hdd/ssd external usb enclosures ?

Hello fellas
I just opened this thread to find out which storage drive enclosures do you guys use (if you use any), which types, how fast they are (in transferring files), how reliable etc..
OK so I have new future revolutionary USB 3.1 external enclosure and it is awesome
Very fast speeds nice slim and small case.. quality made NOT cheap !
This connection is from 3.1 ext. enclosure to 3.0 laptop.
Here are some pics :

 

For my M4 msata 128gb
I had a msata enclosure from muskin (flux or w.e), ASmedia chip (UASP i believe, forgot exact code but you can find it ~) , crap, broke after 6 month, RMA, broke after another 6 month.
I only had nec usb3.0 chip so I was looking at ~200 max read/write. 150~ sustained
For my expresscard to usb3.0 , looking at 120-150 sustained read/write
Brought another msata enclosure (same asmedia chip),
Recently got a tablet with intel native usb3.0, bench read 300~

For a few 2.5" random SSD laying around and deploying windows for my family's machine
I had a sata to usb3.0 cable, with 2 usb head branded bizlink, old usb chip w/o UASP. Never failed me though, push around 150~, probably can test on my new intel usb and see how it performs.

Had some random pcb pulled from 2.5" seagate enclosure(use them "naked"), similar to the bizlink one but they are back into a enclosure for HDD.

 

1) USB will not deliver maximum (except maybe for sequential large files) of any drive it is connected to. Not even the mSATA M6M. Not even with USB3.1 and UASP.

See:
http://www.tomshardware.com/reviews/usb-3-uas-turbo,3215.html

(And yes, I know it doesn't talk about USB3.1... but it doesn't matter; USB is a dullard with data).


2) SATA3 is a specification, it is not political.

3) SSD's simply cannot exceed the interface standard they are connected to the cpu with.

 

You seems to didn't get my point at all
God I know SATA is not political
THE WAY HOW SATA or SSD (and all electronic peripherals and interfaces) IS DESIGNED AND ITS PROTOCOL ! MAY BE.. The compromises btw interfaces ..
U didn't get me what I mean but it's fine
What simply cannot exceed ?
That's kind of unprofessional answer "simply"
Of course it CAN exceed
Nowadays SSDs are exceeding ancient SATA and forcing and pushing to develop next standard
SATAe...! But new and talks about this next storage drive interface is nowhere to be seen /talk about..

Max USB 3.0 speed is 5 Gbit/s (625 MB/s)
Max USB 3.1 speed is 10 Gbit/s (1.25 GB/s)
Thunderbolt 3 speed is 40 Gbit/s (5 GB/s)
Of course these are official protocol (on paper) speeds

With coefficient 0.8 error control parity check times protocol speed 625 will give us theoretical maximum 500MB/s for USB 3.0
Then it need to be calculated again another checking errors called buffering to deliver data 100% undamaged so 500MB/s times 0.75 will give us exact same speeds as I achieved 375/380MB/s there is of course tolerance +/- so speeds will be balancing ..

 

I found something interesting here the company called super -talent made USB 3.0 flash drive called RAM DISK .. and apparently it has enormous speeds
http://www.dramdisk.com/

 

No, I get your point. (You do not understand how computers work).

You sure have a funny way of trying to learn though.

Btw, that dram disk is not the first of it's kind...

See:
http://www.eboostr.com/

I used eboostr before I bought a real SSD (Intel 520 Series OP'd to ~50%), but afterwards, the 'benefits' simply vanished. Not only because SSD's got better. But because the O/S did too.

Today, both of those products are not interesting nor recommended in any workflow where reliability, dependability and availability of the system is important. Just run the most current cpu/platform you can afford and max out the RAM and run Win8.1x64Pro - yeah; it is that good (and has been since Win7x64Pro).

I did not give you an 'unprofessional' answer above. Re-read my post again. USB with data is a dullard - period.

And trying/wishing to make something (digital) go faster than what it was designed for is... a very naïve way of looking how computers work.

 

I don't understand how PCs work hahah u funny dude ..
ok .. come oon
of course ram disk been here ages but NOT in USB flash drive way ..your link not interesting me at all
oh u saying all sudden win 8.1 is great .. and b4 everybody been saying how crap it is .. so pathetic..
Jeez the worst SSD from intel u had overpriced marketing
I would NEVER use that crap program what you linked..
I am sure ppl would disagree with you ..
You STILL didn't get it that it is ONLY all about fast ''user'' file transfer which is getting faster and faster .. doesn't matter what OS you have
Of course it matters on OS only because Microsoft simply stopped supporting old windows but if would be all same drivers avail. on for example win XP 64 everything wit transferring files would be the same.
And Ram disk is DEFO avail. on xp too so ..btw I never used RAM disk, I never been interested in this.

''And trying/wishing to make something (digital) go faster than what it was designed for is... a very naïve way of looking how computers work.''
That design man is always replaced with another design ..
And naive and slow is rather how old SATA interface we have..
Storage drives suposd to be connected via PCIe long time ago .. and not SATA
The main reason why SATA interface/peripheral is not moving forward is simply bcos it would be too high power hungry and that would have huge bad impact for portable PCs !

I suggest you to read this interesting article and try understand MY POINT and how ''SATA'' becoming LAME !

You really think the USB is doing RAM disk type service? You do realize it only has a program that loads a real RAM disk and doesn't touch the USB drive again. sigh...

That crap program you wouldn't use, I would agree with you - today.

But back when I was fooling around with it, it beat any SSD previous to the Intel 520 Series and that was back with USB2.0 speeds too.

I'm not saying all of a sudden how great Win8.1x64Pro is - I've always said it. The newer O/S is the most stable and reliable O/S available right now. As for the crybabies saying it is crap? They can argue design/layout all they want - I just learned to do what I need (in a whole 10 minutes of trying...) and found it to be better than what I had. You believe everyone else thinking it's crap - I have a whole boatload of systems running Win8.1x64Pro and have yet to see one fail in the last four years since I started with the Win8 preview (so much different from XP, Vista and even Win7...).

You come here to ask about external drive speeds via USB (crummiest link ever) and you have an opinion of Intel SSD's? What a surprise.

Kiddo hasn't been my nickname for decades, please drop that when referring to me, okay?

 

No no
Don't get interested about that super talent RAM disk crap .. I just only put it here what everybody would think of ..
I know already it is TOTAL CRAP !
Of course back in day SSD were different older nand chips , slower controllers etc.. but technology of SSD going forward very fast ..
About WIn 8.1 of course it is better now when microsoft realised how ppl hates it so they released enormous bunch of updates so it is more stable now..
I really want to focus on SATA how it slows down speed of PC storage drives ..
Sorry for that naming .. I will delete it .. Check that link i pasted at end ..

 

No reason to focus on SATA anymore... M.2 is poised to bring them a quick death (soon-ish).

And... how does this relate to external enclosure speeds over USB?

 

Yes mSATA and M.2 is ok but NOT in laptops because in laptops it is just FAKE!
In laptops it is used just like adapter and again it is going to SATA (whichever version I ,II,III...)
What is disadvantage on laptops from desktops is, they are lack of PCIe port !

That small connector PCIe x4 would perfectly fit in laptops as it is small !

And... how does this relate to external enclosure speeds over USB?
Very much .
I purchased enclosure which is M.2 support only so I had to purchase mSATA to M.2 adapter to fit mine mSATA SSDs .. I don't have M.2 SSDs yet as they are not different M.2
ONLY in size ..

 

mSATA is SATA.

M.2 is PCIe (when wired properly on the notebook and you have a PCIe SSD attached to it).

The difference is not just in size - the electrical design underneath is what separates them by miles (when done right).

Using a connector/adaptor from an mSATA SSD to an M.2 enclosure over USB is a waste of money and performance. Sure, you get to play with your enclosure for now - but over USB there will be huge limitations even when you get a 'real' M.2 drive.

 

No mate I completely disagree M.2 is same as mSATA the difference is just in size and connector type.. that's it
and u cannot wire it you can just insert it , connect it .. and not possible connect it improperly
check this post : http://forum.notebookreview.com/threads/msata-vs-m-2.762651/#post-9792445
And USB 3.1 enclosure is DEFO NOT waste of money !
It is smaller faster and DEFO not expensive it cost me just £30 with M.2 adaptor
Well of course USB like such will never outperform PCi-e x4
Still better than my old usb 3.0 SATA where transfer speeds were lower..
But we will see, what future will bring ..
I really waiting for laptop which would support PCIE x4 or maybe x8 for storage drives and + USB 3.1 type c peripheral connector ..
That would /will be AWESOME

 

You can disagree all you want. Read, live and learn. I am not talking about 'us' wiring it as we want - I am talking about the M.2 specifications that use different 'keys' to internally wire it to the PCIe lanes or through the SATA lanes (huge differences - especially in latency).

As for your posted link... what about it? And the video link to the 2.5" Intel 750 SSD? You know no notebook will ever support that drive, right? (Why? Interface, Power and Cooling requirements place it firmly into desktop territory).

USB 'any version' as a data transfer protocol is a poor solution when real performance is needed. Again, use it and learn.

USB3.1 Type C connector availability will be welcome - especially if it incorporates the 100W power handling capability. Otherwise, USB is USB... and USB is yawn when you want performance in all aspects of a storage subsystem - yeah, even with it's theoretical 10Gbps speeds...

 

USB is designed to just to occasionaly transfer data of course.. it is defo not designed to boot and run windows..
but still again I disagree with you that usb 3.1 is poor it has very good advantages compare to its previous versions ..
cheers anyway
PS: And don't worry even laptop will support higher and higher performance in future ..
NEVER say NEVER !

 

Some laptops, Clevo for example, already have M.2 PCIe SSDs x4 lanes. PCIe Gen 3 and NVMe will be out this autumn.

 

How's speeds on x4 lanes? On that clevo..
Looks like that laptop released 7 months ago.. Ages ago..
Other laptop brands obviously are not interested implementing it in their laptops..

 

These are just CDM, AS SSD, ATTO benchmark speeds.
http://www.eurocom.com/ec/benchmark(88)ec

Other laptop brands follow the crowd. Thin and light. There is only one high performance laptop brand now. Clevo. While they have BGA machines they are the only one with a socketed desktop CPU or Xeon, socketed GPU. In a 15.6" and 17.3". The SLI, desktop CPU is coming. The P570WM, with those features can still be found but it's, basically, EOL.

 

What a nonsense put plextor m6e to pcie x2 only ?? How's that even possible when slot is only x4 ?
And anyway they should test all 3 in x4 lanes to see the diff. btw SSDs
But I know or we know that samsung XP941 and SM951 has highest speeds right now.. Only this one SSD is worth putting in 4 lanes as delivers speeds above 1GB/s
I've seen plextor m6e black edition benches 4 lanes and the difference btw SATA III were just 200MB/s more in read speeds, breaking that SATA III barrier "500" MB/s is not huge.

http://www.anandtech.com/show/8979/samsung-sm951-512-gb-review

 

No nonsense! The Plextor is not a PCIe x4 lane drive. It's PCie Gen II x2 lane.
http://www.tweaktown.com/reviews/6945/plextor-m6e-black-edition-512gb-pcie-ssd-review/index.html

Give me a SanDisk Extreme Pro SATA SSD over any x2 PCIe SSD in an OS environment.

 

|So plextor doesn't support x4 pci-e?
so that's why is slower than samsung SSDs...

SanDisk Extreme Pro : I meant why they making these pci-e 2 lanes only when it is same as SATA III ..
then i wont bother and yes ,will buy an 2.5'' SSD..
PCI-e would be worth installing if it would have significant speed boost over SATA
If pci-e ssd it is NOT over 1GB read/write not worth getting it..

 

They are making them because the sequential numbers are high. People see that big number and believe it's faster than a SATA SSD. For large file transfers it's true but in an OS environment high performance SATA SSDs will beat a PCIe x2 lane.

 

Marketing like everything..
