My SSD Only Supports 500MB's Read and 175 MB's Write!


Recommended Posts

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

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...

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

bipolar ?

If that's the case yeah better leave him alone.

He's never specified the exact issue. If it is BP it is far beyond what I experience...which is already a pain. :p

I played wow with a bipolar guy for a year. It was a hell of a roller coaster ride lol ;) he was a nice guy tough.

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?

how about you answer the question, which USB spec are you running against? USB 1, 1.1, 2 or 3?

and post a picture of a hard drive benchmark test like Crystal DiskMark or HDTac or something similar

it's the 2010 mac mini, so if he's using usb it'd be 2.0

edit: more specifically this is the SSD that he got that he claims is external because it came with a cord http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=78D9B390A5CA7304

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.

Thanks for the article now it is easy to see what he is getting at, albeit it would appear that he is using the transfer kit for using the SSD as an external drive. . .some peoples kids.

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

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.

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.

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.

    • Google begins rolling out its post-Epic Play Store billing model next week by Karthik Mudaliar Google has confirmed that its redesigned Play Store billing and fee structure will take effect on June 30, 2026, in the United States, the United Kingdom, and the European Economic Area. The changes will let eligible developers offer their own payment systems or send users to an external website for purchases, while separating Google’s platform service fee from the cost of using Google Play Billing. The rollout puts concrete dates and detailed rate cards behind the broader Android policy overhaul Google announced in March. That announcement followed a proposed settlement with Epic Games intended to resolve their long-running disputes over app distribution and payments, although the U.S. portion of the agreement still requires court approval. Under the new billing choice program, developers selling digital content or services can display an alternative payment option alongside Google Play Billing. They may also direct users to their own websites to complete a purchase. Developers can use Google’s standard payment-choice screen or design one that complies with the company’s user-interface rules. Choosing another payment processor does not eliminate Google’s cut altogether. The company will continue charging a service fee for transactions associated with apps distributed through Google Play, regardless of whether payment is handled by Google, an alternative provider, or a developer’s website. Google argues that this fee covers the value and infrastructure provided by Android and the Play Store. For developers earning up to $1 million annually, the service fee will generally be 10 percent. That rate also applies to auto-renewing subscriptions. When Google Play Billing is used in the U.S., U.K., or EEA, Google will add a separate 5 percent billing fee, and developers processing payments elsewhere will not pay that additional charge. This means Google’s familiar flat 30 percent commission is disappearing, but developers will not necessarily see a dramatic reduction on every transaction. An in-app purchase from an existing user processed through Google Play Billing can still reach a combined 30 percent. The biggest savings are likely to come from subscriptions, smaller developers covered by the $1 million tier, and companies able to move customers to their own payment infrastructure. Google is also offering lower rates through its Apps Experience and revamped Games Level Up programs. Apps and games that satisfy the company’s requirements can qualify for 15 percent service fees on new-install transactions and 20 percent on existing-install transactions. The criteria include performance and reliability standards, support for additional Android device categories, and selected platform features. Those program rates are scheduled to become available in the initial markets and Australia on September 30. For consumers, the immediate effect will depend on whether developers adopt alternative payments and pass any savings on through lower prices. For developers, however, June 30 begins a more flexible but considerably more complicated Play Store economy in which distribution, billing, install dates, revenue thresholds, and program participation can each affect Google’s final cut. Google is also separately developing a Registered App Stores program designed to simplify the installation of qualifying third-party stores. That initiative is expected to arrive with a major Android release later in 2026 and will launch outside the U.S. first. Google says the rest of the world will receive the changes by September 30, 2027, although billing rates for markets outside the US, UK, and EEA have not yet been announced.
