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!

actually USB2 supports 480Mb not MB (which is 35MB per second) ;) USB3 isn't bad at 5Gbits or 625 MB a second

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.

No.

"USB 2.0: Released in April 2000. Added higher maximum signaling rate of 480 Mbit/s (effective throughput up to 35 MB/s or 280 MBit/s)"

An M4 would be a "bare" drive.
I've reread the OP's post about 10 times and still can't real decipher it. :s

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..

ah, didn't look up that specific drive, was just going by past experience with ssd's sometimes having mini usb ports

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.

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

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:

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!

Yup. 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.

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.

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?

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
