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

kevpan815: dude, if everyone but you says that you are wrong they are usually right. Take your machine to a mac store and get them to put the new ssd in it. Stop freaking out about drive speeds and your warranty period.

Extra note:

lol this guy. I'm such a lurker but this is (almost) worth a post.

Check the original thread here: https://www.neowin.net/forum/topic/1123472-finally-placed-my-order-for-an-ssd-from-crucialcom

He can't be arsed to change the hard drive himself or take it to the mac store for fear of his warranty running out and now he is freaking out about read/write speeds claiming that the ssd is designed for external use because it came with a usb cable.

I say just leave it. There's no point asking a question if you won't accept the answer.

This and this, as others said before about USB 2.0 and the whole shenanigan about MBps and Mbps, they're correct :/

You are not getting full speed out of your SSD when it's connected via USB2. It is impossible, but since you just ignore what everyone's saying then it's pointless.

Do some benchmarks and learn the difference between a megabit and a megabyte. You'll soon see you're completely wrong if you bother to take the time to listen. People are just trying to advise you that the way you're using your newly purchased SSD is useless as USB2 is crippling it. If you don't want to take anyone's advice and learn then it's pointless even posting.

Is this the guy who paid USD 200 for a RAM upgrade?

I think he is just insane. Lock thread and ban.

Well that is pretty uncalled for. Everyone has to learn somewhere no?

Granted, from what I have seen in this thread and other threads that were linked to in this thread, the OP seems pretty adamant on not wanting to learn and insisting they are right, however if they are just able to accept the fact that most people are in fact here to help those who are looking to help themselves, well as I said, they can actually learn a whole lot if they so choose to do so.

With that said, comments like this one do not really help matters, and in fact, they probably make them worse. Just saying, it was pretty damn unnecessary to say, even if you do think it is the truth. Just proves that the old adage "if you do not have anything nice to say, do not say anything at all" also applies to the internet, even if people feel like they can say whatever they choose to another human being as they are behind the safety and anonymity of their IP address/monitor.

I am sure I just wasted my time posting this, but I felt it need to be said, and it also does apply to a few other responses in this thread. Sometimes people are just downright cruel. And as I said I do admit, it seems as though the OP does not want the help even though there are those offering it, however that is their loss, no need to fuel the flames and gang up on them.

  • Like 3

Where are you people coming up with 480 Mbps = 35 MB/s because your math is way waaaaaaaaaaay off.

Bytes = 8 bits, hence 480 Mbps aka Million bits per second divided by 8 = ~60 MBps aka Million bytes per second (that's the absolute theoretical maximum but because of overhead it's never that fast). Even though it can't push ~60MB/s perfectly that's still a very big jump from 35MB/s which you folks keep spitting out as though it were accurate to any degree.

USB 2.0 is theoretically capable of ~55-58MB/s sustained transfer speed if there are no other devices on the particular USB controller.

The OP simply made a booboo of sorts, I could tell that from reading the post he made - the rest of the posts hence have been basic garbage overall and a lot of misunderstandings and mistaken values for the potential, theoretical, and even real-world performance of USB 2.0.

Better luck next time people, and don't go so far off-track will ya?

because USB isn't a 1:1 translation in speed

quote from wikipedia since I don't feel like writing a full description myself right now

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) (now called "Hi-Speed"). Further modifications to the USB specification have been done via Engineering Change Notices (ECN). The most important of these ECNs are included into the USB 2.0 specification package available from USB.org:[13]

and from tech republic

4: Actual data throughput

Actual data throughput is usually much less than the maximum advertised USB specification and is a function of many variables, including overhead. Actual throughput in practice is typically up to 35 - 40MB/sec for USB 2.0 and may exceed 400MB/sec for USB 3.0. NEC recently demonstrated its new USB 3.0 controller transferring 500MB in 4.4 seconds or ?only? 113.6MB/sec. Symwave and MCCI claim to have demonstrated over 270MB/sec data throughput at the Intel Developer Forum in September 2009.

sorry, but the rest of the posts aren't "garbage" but a bunch of people that realize there is more to the USB spec then what you are told you get...

so, the OP pm'd me and said he fried his system and it's somehow our fault

all i have to say is he obviously didn't follow the links with step by step directions we gave him very well

Can anyone forward me the PM from him....I'd love to read them. I have loved reading this thread....it's been a treat.

here's the two PMs i got from him

all the first pm said was "I now have a dead system and it's your guys fault"

second one said

The Drive does NOT even fit in my system, Just FYI! Now I have to save up $599.99 + Tax just so I can replace the system itself, and that does NOT include the fact that at some later point in time I will have to pay $149 for Apple Care, and $69.99 for an External Super Drive! Thanks a lot!

edit: and i just got a reply after asking why he doesn't take it to an apple store

No, that will NOT work, I used Pliers to undo all those Non Removable Bolts in the System, I just plain am going to have to save up $599 U.S.A. Dollars from my January Public Aid Paycheck (Social Security Disability) and buy a Late 2012 Mac Mini which will have USB 3.0 Ports on it. There are scratches on the system from where I was using the Pliers and that will most definitely Void my Warrenty. I also damaged the Heat Sync while trying to get the HDD out of the system. I am just plain going to have to buy a new system after the Holiday's!

he tried to use pliers to remove the bolts around the hard drive and ruined the heat sync. he brought it upon himself for not using the correct tools

This thread. :|

All those years that I did tech support and fixed computers...had no idea what was really out there.

just a reminder of the link we gave him with instructions on replacing the hard drive http://www.ifixit.co...lacement/3113/1

he probably completely ignored the link back when it was posted and never even clicked on it

Dear god :s , OP is probably PMing people because of all the bad comments. If someone can get through OP's head then that'll be great; other than that, this thread is just giving everyone lols :/

Look, the OP came here to gloat, not looking for advice. He seems happy with his setup in his own roundabout way and he probably wouldn't be able to tell the different between running off an SSD and running off a FDD.

The truth is that he doesn't need the power because his computational needs are basic (not running any intensive apps), and he just likes to play around with Operating Systems and keeping his prized Apple hardware intact, as this is all just his hobby.

I have seen from previous threads that he has a mental illness. So guys cut him some slack, it's not easy living with a mental illness. He is quite happy with this setup and he is getting satisfactory performance to him.

If he feels the need in the future to go even faster, he can make the decision for himself to do the upgrade when his Mac Mini is out of warranty and then he will have nothing to lose .

(personally I would just do the upgrade now and keep the original drive spare for warranty purposes, and switch it back if I needed to send it in, as the Mac Minis are dead simple to work on unlike all other Apple hardware and it is the one thing you can easily take apart without breaking anything).

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!

Well done sir, youve invented a new performance bandwidth for USB 2, your confusing Megabits with Megabytes, even a SATAIII SSD struggles to hit 480Mb (megaBYTES)/sec Read/writes on SATAIII/USB 3.0

you should come up with an aftermarket solution, you could make millions selling it to users with usb 2 but want usb3 speeds.

Removed offensive word.

This thread ought to be locked and the OP's posts largely ignored, just like those of a certain banned member with the initials A.B.

    • Yup, that's a doozy right there 😄
    • It's a bundle of tools created by a variety of people, so things can go wrong sometimes. It's a great addition to Windows, and I use a lot of the tools on a daily basis. Also, it's still a 0.**** release so quick updates are to be expected 😉
    • Oh, I did. And it's even worse than I was hoping! Besides a lot of techno-babble jargon (yes I understand 100% of it but it's still all just techno-babble) there's 2 key points that make me super-weary about even considering testing this out. -- By default, after installation, a relay is automatically set up, so you do not need to care about that. * Non-chatmail apps use email servers as a long-term message archive while chatmail clients use email servers for ephemeral instant message relay. * Supporting the full variety of classic email setups would require considerable development and maintenance efforts, and complicate making chatmail-based messaging more resilient, reliable and fast. -- Basically, the end-user device is the 'server' (relay) so there is NO ARCHIVING whatsoever because every message is necessarily ephemeral. Great for techno-paranoia (and for illicit activities preferring no tracks to cover) but terrible for everybody else. It's also ironically contradictory to engineering principles of redundancies besides the transport layers due to the explicit absence of any persistent storage. Instead of 'classic email address' retaining multi-GB messaging archives on its server, now every device must retain 100% of those storage demands. (Email messages were originally meant to be short correspondences, not the multi-MB attachments boondoggle that now exists with unlimited spam engines flooding every potential recipient.) Any device swap or reset (or loss) makes the entire message history go bye-bye forever... lest there's an off-device auto-archival "relay" mechanism that's really a separate server that holds onto all transported messages (an email server) that utilizes 'chatmail email address' identities (like an email server) and its own persistent storage archive (like an email server). But... this solution is hoping to exist alongside real-world email address identities (based on the email server relay pathway) but simply render messages in chat thread format in an ephemeral manner (with contents being encrypted, and messages auto-expiring) ... In the end, it's a chat app/experience for the Web3/P2P-at-all-costs zealots. (I have accts on all sorts of federated web3 services so I understand the technical and non-technical alike.) For any practical users, however, it's just another service to download/install, register, cross-share id cards/qr codes, but know that there's no history/archive whatsoever (by design) so no account/message recovery whatsoever... update the device, install a bummed update patch, or dare upgrade your device... all history, poof, gone. Ya gotta start everything over again like they're a brand new person.
    • You've tried DuckDuckGo and Brave Search, now get serious with SearXNG by Paul Hill Over the last decade, it has become quite trendy to dump Google Search in favor of privacy-preserving alternatives such as DuckDuckGo, Startpage, and Brave Search. These search engines have done a very good job at highlighting dodgy practices by Google, such as adjusting search results based on what it thinks you’ll like (filter bubble) and stalking you around the web to advertise to you. While these search engines are good starting points when compared to non-private services like Google, there are still quite a few issues with them. For example, both DuckDuckGo and Brave Search require running non-free JavaScript in your web browser, which is comparable to running proprietary software on your computer, meaning you can be sure about what it’s actually doing in the background. Another issue is that these search engines are hosted on the respective companies’ servers, and you are using a service that you don’t control. Finally, DuckDuckGo, while offering privacy features, relies heavily on Microsoft’s infrastructure for its results and, in the past, has permitted Microsoft tracking scripts. If you are looking for a more private search solution than DuckDuckGo, Brave Search, and Startpage, then I recommend taking a look at SearXNG. It is a privacy-respecting metasearch engine that can be used via different public instances, which is useful for mobile users, or you can install it on your computer or server and run it locally with maximum control. Unlike Google, Bing, or Brave Search, which crawl the web and have their own search indexes, SearXNG is a metasearch engine, meaning it taps other search engines, stripping your identifying data, such as IP address, user agent, and cookies, in the process. Your search query is sent to the other search engines you enable before aggregating the results. SearXNG has deployment flexibility. If you are a casual user or a mobile user and don’t want to run SearXNG locally, you can use a public instance that is hosted by someone else. The main problem with this is that you are putting trust in the maintainer of the instance regarding stuff like logs that they may keep; good hosts should have a privacy policy explaining their policies. If you are trying to use SearXNG, you can also install the software on your device and then head to 127.0.0.1:8080 in your browser and search from there. While you don’t have to worry about a third-party admin like the public instances, search engines could ultimately block your IP address if they frown on you pulling in their search results locally. If you want to run it locally, it’s a good idea to use proxies or VPNs to hide your actual IP. You don’t have to worry about this with a public instance, as search engines never see your IP address. The main privacy benefit of using SearXNG is that it isolates your identity from the underlying engines that it’s capable of searching, such as Google and Bing. These search engines will only see requests coming from a generic server, so they can’t profile you and create a bubble filter that influences what results you see. This also ensures that your search engine doesn’t turn into an echo chamber that prevents you from reading alternative points of view. As a free software project, you are allowed to inspect SearXNG to make sure there are no negative features bundled inside. This sets it apart from the privacy search engines mentioned earlier because you can’t check their source code. As a meta search engine, you are not restricted to getting results from one source. Due to the fact that it scrapes content from other websites, your SearXNG instance will periodically get blocked from different providers, so it’s good to select a range of sources as a backup. While enabling all of the services will give you great results, this can make searching slower. I am personally happy with slower searches for the best results, but you can always check which providers are slowing down your search from the search results page and disable them to speed things up. If you want decent results quickly, enable the main search providers such as Google, Brave, DuckDuckGo, Qwant, Bing, and Yahoo. This way, you get wide coverage without the latency. On the Engines tab in Preferences, do note that there are different tabs, such as General, Images, and Videos, with their own providers that can be toggled and are not covered by "Enable all" while on the General tab, so be sure to dig into each. Just a note, if you want to enable everything, press "Enable all" in one tab, then hit save at the bottom of the page, then do the next tab, and so on. If you press "Enable all", then do that in each tab, and then save, nothing will stick. When I had just some of the search engines enabled, I searched “define nefarious” and results came back with the definition of “define” - obviously that was a sucky result. However, when I had everything enabled, it found dictionary pages for the word “nefarious” and even had an inline definition on the sidebar, which is quite nice too - that was delivered by WolframAlpha for anyone wondering! Probably the worst thing about this meta search engine is that the engines you select are saved with a cookie, so you must enable them on every new device you use SearXNG on, including if you decide to go into incognito mode with your web browser. Honestly, I would say this is the most annoying aspect, and perhaps if your browser lets you choose a separate private browsing search engine, then it would be best to use DuckDuckGo for this portion of your browsing. Another weakness of SearXNG is the random blocking of it by search providers. When you are on the results page, expand the “Response time” box, and it will show things like “Suspended: too many requests” or “access denied”. This is why it is good to enable several providers so that there is always a fallback to get results from. I won’t pretend SearXNG will be for everyone, however, if you enable all of the providers and put up with the slower response time, the results can be really amazing. Even if you don’t want to use it as your daily driver, keeping a bookmark handy that links to it is a good idea if you ever feel like doing a deep dive into a niche topic where other search engines are just failing to bring up any good result, due to the amount of sources it looks on. If you’re interested in radical user control over the software you use, installing SearXNG locally can also be a good idea, but be prepared to be temporarily blocked from sites if you trigger bot sensors without a VPN. Personally, I’ve opted to use a public instance, rather than install it myself. If you want to use it via a public instance, head over to searx.space to find a provider. Let us know in the comments if you have used SearXNG or its predecessor, Searx. What do you think about the quality of the results?
    • Dear Neowin, If it is not too much trouble, can you start using the new-ish designations for Insider Preview? "Experimental" is different than "former Dev" as it can apply to different models, eg 26H1 or 26H2 etc, right? No need to seed confusion IMHO. And, please "finally" update your graphics. OK?
