kevpan815 Posted December 5, 2012 Share Posted December 5, 2012 You guy's gave me he** for using my 128 GB M4 SSD Externally. Well I just wanted to let you guys know that my SSD only support's 500 MB's a Second Read and 175 MB's a Second Write! It is indeed designed to be used Externally, NOT Internally as USB 2.0 Supports 480 MB's a Second! Just FYI! Link to comment Share on other sites More sharing options...

neufuse Veteran Posted December 5, 2012 Veteran Share Posted December 5, 2012 actually USB2 supports 480Mb not MB (which is 35MB per second) ;) USB3 isn't bad at 5Gbits or 625 MB a second An SSD on USB 2? Err... wha... Some SSD's had USB ports on them... gawd knows why they thought this was a good idea, but some had them... Link to comment Share on other sites More sharing options...
+LogicalApex MVC Posted December 5, 2012 MVC Share Posted December 5, 2012 Some SSD's had USB ports on them... gawd knows why they thought this was a good idea, but some had them... I can only guesstimate that it would have been for a drive recovery scenario where you were temporarily connecting it to access some of the data. But I concur that makes no sense... To actually place an SSD on USB 2 as an external primarily is grossly a waste of money. Even the slowest HDD would handle that scenario just fine.

If you ever figure out their reasoning let me know *lol* I always thought why?... only thing I could think was for easy mirroring of a hard drive to the SSD via USB but that's still a dumb idea if you understand the difference between storage on SSD and HDD's like 512 vs 4k sectors and how mirroring one to the other is kinda an ehh idea to do..

I've reread the OP's post about 10 times and still can't real decipher it. :s He got an internal SSD with a USB cable, thought it was external (I guess because SSDs look like they come in a case compared to a spinny drive), plugged it in via USB 2, apparently thinks it's now running at nearly full speed. :laugh: I assume it's just sitting on his desk too, which I suppose isn't the worst with an SSD, but it just adds to the ridiculousness.

They're cheaper than a flash drive, and slightly more durable than a portable disk drive. I guess there's that. Makes more sense if you have USB 3.0 anyway.

Brandon H Supervisor Posted December 5, 2012 Supervisor Share Posted December 5, 2012 and once again kevpan, you didn't listen to us, only yelled at everyone that was trying to correct you the ssd you got IS an internal drive. the cord is only for you to easily clone your old internal over to the new drive before putting the new one in we even linked you to some instructions on how to easily do it all but you chose to ignore us and just attack everyone trying to help you Link to comment Share on other sites More sharing options...

Interesting. If that's the case, there is NO way that he would be getting anywhere near the 500MB/s that he stated. Even 50MB/s would be stretch. :rofl: Link to comment Share on other sites More sharing options...

I personally use a hybrid drive externally. But i use it on eSata as using it on USB 2 would make no sense at all. Link to comment Share on other sites More sharing options...
Shane Nokes Posted December 5, 2012 Share Posted December 5, 2012 Folks, he has admitted on his own that he has mental problems. Feeding into it only makes it worse for him and everyone else. Sometimes he literally cannot help the fact that he won't listen and gets agitated. WRONG! IT IS GETTING ALMOST FULL SPEED AS IT IS GETTING 480 MB'S A SECOND OUT OFF 500 MB'S A SECOND! I EVEN PLAYED STAR TREK D-A-C (FROM THE MAC APP STORE) YESTERDAY AND HAD NO PROBLEMS WHATSOEVER! Kevin, this is a case where you are wrong. Don't make things worse on yourself by arguing with people who know what they are talking about. You and I have had this type of discussion many times over the last several years. Walk away and do the proper research when you're well, not when you're sick and cannot judge things well, ok? Link to comment Share on other sites More sharing options...

I EVEN PLAYED STAR TREK D-A-C (FROM THE MAC APP STORE) YESTERDAY AND HAD NO PROBLEMS WHATSOEVER! Are you sure you aren't using E-Sata? USB 2.0 support 480 Mbps which as others have observed is 35MBps. Even if the drive supports 550MBps (which it probably does by SATA3) the USB 2.0 interface will slow it down to 35 :\ USB 3.0 could give you those kinds of speeds, but not USB 2.0 Link to comment Share on other sites More sharing options...

neufuse Veteran Posted December 5, 2012 Veteran Share Posted December 5, 2012 which USB connection are you using exactly? USB1, 1.1, 2, or 3 and does the USB to SATA bridge even support what you are using? Link to comment Share on other sites More sharing options...
neufuse Veteran Posted December 5, 2012 Veteran Share Posted December 5, 2012 how about you answer the question, which USB spec are you running against?

+virtorio MVC Posted December 5, 2012 MVC Share Posted December 5, 2012 USB 2.0 is 480 Mbps (mega bit). Your SSD is 500 MBps (mega byte). So in fact USB 2.0 is 60 MBps, and once you take the protocol and overhead into account it's closer to 30 MBps. But you seem pretty adamant on not believing what people say so, whatever.

But you seem pretty adamant on not believing what people say so, whatever. yeah, just so people know 500 MBps = 4000 Mbps USB2 maxes out at 480Mbps that's 8.3333 times slower then the SSD's max speed now if this was running under USB3, yeah you'd get good speed, but USB2 why even have a SSD you are going slower then your mechanical HDD ahhell 1 Share Link to comment Share on other sites More sharing options...
+BudMan MVC Posted December 5, 2012 MVC Share Posted December 5, 2012 yeah it comes with a cord The Data Transfer Kit makes it simple to copy everything on your hard drive, including operating system, data, email settings and applications, to your Crucial m4. The kit includes the EZ Gig III Cloning and Imaging Software for Windows?, ShirtPocket's SuperDuper! for Mac?, a USB to SATA cable and a Quick Start Guide. Upgrade your notebook drive in just three simple steps. Not sure why you can not believe the USB 2 spec. http://www.usb.org/developers/docs/ http://www.usb.org/d...rs/usb20/faq20/ 1: What maximum speed was finally chosen for the USB 2.0 spec? A: The USB 2.0 specification has a design data rate of 480 mega bits per second. This is just fact, if you don't believe it - then download the spec for yourself - I listed the url for it.

HawkMan Posted December 5, 2012 Share Posted December 5, 2012 yeah, just so people know 500 MBps = 4000 Mbps USB2 maxes out at 480Mbps that's 8.3333 times slower then the SSD's max speed now if this was running under USB3, yeah you'd get good speed, but USB2 why even have a SSD you are going slower then your mechanical HDD Also USB is 480Mbps BURST transfer. it's the highst USB2 will go in a single burst, but it doesn't transfer at that speed constantly, hence why it's called burst.
