MacBook Air :: How Long Will NAND Flash Memory Last
Oct 26, 2010
Was looking to buy a new laptop to replace dying old XP Dell and compliment iMac. Was thinking of a 13" Macbook Pro but have got interested and excited by this new Air. Its the instant on and portability that appeals........ but on this forums in places and elsewhere on internet (even Wikipaedia) there appears to be concerned that NAND flash memory has a definite life.... so many 1s and 0s changing before it slows right down.
Is this right... how long will it be.... can it be refreshed by copying stuff, doing something and then loading back up.... or has it to be replaced. The iFixit teardown suggests it is replaceable but at what cost. ie don't want to buy one only for the memory to give up the ghost in a year or two.
Every time I use my MBP alum a lots and after I close everything the machine gets and still very slow and I have to restart my Mac to refresh the memory.
My mac spec is MBP alumenuim 2G 2.2 .
I would like to notice I did not face this problem in the past with my old MBP 2007 4g 2.4ghz
So anyway I could free the memory or something instead of restarting the machine
1) Will it perform as well as the Flash memory in a MBA? They load apps stupidly fast, will the performance of a SSD in my MBP match that? 2) Are they hard to fit?3) I know there's loads of threads about this, but which would you recommend? I will be getting one for my dad's 13" MBP as well, will they both be the same size?
For MacBooks with SSD drives and a SD card slot; is it practical to insert an "empty" SD card there and use it as spare flash memory to store files etc? Any downsides to doing this? Will the OS detect it like its a spare drive?
I read in another post here that the new all-flash memory is only good for about 100,000 saves, or 5 years for the average computer user. Is this really true? It seems silly to promote using hardware that puts such a limit on the user..
I noticed the new Macbook Pro with Retina display has flash memory instead of a Hard drive. I love the new features and I want to buy it but I'm very skeptical of this flash memory. Can someone please help explain it to me. Is it better than have a hard drive in your computer?
I know that the iFixIt tear down reveals Toshiba flash chips on the 11" MBA, but I was curious to know the following specs on the 13" MBA.
Does Apple use different suppliers for the different capacities/models (i.e. Samsung, Hynix, etc.)
I could make some guesses from the benchmark tests, but would like to have hard specs.
I tried contacting Apple, but the only thing they would tell me is the capacity available for purchase. I also don't have the guidelines to reference the flash specs based on the model of the Toshiba flash.
I just bought an 8 gig memory stick - that was advertised as being PC & Mac compatible. I put it in and it loaded fine. But when I tried to copy a file to it - it told me that the file name was too long. The name wasn't that long so I renamed it '1.jpg' - but got the same response. I tried other files and go the same. So I launched 'Disk Utility' and reformatted it using the 'Mac OS Extended (journaled) option. This worked fine. But this time when I tries to copy any files, it told me that the operation could not be completed because I did not have sufficient privileges to do this.
My 17" ALS Imac is not booting (tiger OS). I will preface this by stating the hard drive has been whining and making a lot of noise for the past year or two. Anyway, a few days ago it froze up and I had to pull the power plug. I tried to restart and got a plain gray screen and saw a question mark. Now when I try to retsart I get a plain gray screen with the following message:
Invalid memory access at: 0SRRO: (then a long address) WELCOME TO OPEN FIRMWARE To continue booting type "mac-boot" To shut down type "shut down"
After I type mac-boot the hard drive (or cd drive?) starts racing quite loudly and then it freezes up and displays a grayish screen with dozens of short, yellowish, horizontal lines and I have to pull the plug again. I have been anticipating a hard driver failure for a while so at first assumed that was the problem, but now I see this memory error and am not so sure. I was planning to purchase a 1 TB drive and maybe upgrade the OS at the same time . Basically I am wondering if I should go ahead and do this or run some additional diagnostics first in case it's something else?
My dad has a new 27" Core i5 iMac. When he plays a very long slideshow, iPhoto consistently crashes around the 8-minute mark. Sometimes he gets an error message saying "iPhoto unexpectedly quit" and sometimes the slides just quit coming up, even though the music keeps playing.
It doesn't matter from which event the slides come, although it seems to happen on his pics only and not on the pre-installed pics from Apple.
One last data point, this never happens, even when viewing the same slideshow, on his 13" MacBook Pro, which he bought at the same time.
It seems to me like a memory leak, or, less likely, some kind of GPU overheating issue. He's tried rebuilding his photo library, which changed nothing.
My computer has 500 GB of capacity, but I have seen that every time I open a file or boot something the memory used rises a little. Is this normal? It is the first time that I have seen.Â
Info: MacBook Pro with Retina display, OS X Mavericks (10.9.4)
Lately I have been considering an issue and couldnt quite come to the right answer. is it true that certain programs cant be installed on flash memory? I have been looking at the 15" i7 but i hear that there might be an upgrade due around 2011, does anyone know anythng about this and what it is likely to include? Reason is i would not like to spend the money on the 15" only to find that a later greater upgrade is avail. in your opinion, is the upgrade likely as soon as april-may next year and is there likely to be any significant improvements?
When I plug in a USB Flash Memory, it instantly pop up a message that says I need to restart my computer, by letting the power button presed for a while or pressing the restart button (Which I dont have). It has a 0/1 button-like image on it.
At first I thought my USB had a virus or some corrupt file, but when I realized there were no mac files (Just Windows and universal), I pluged in another USB, and the same thing happened.
I have an issue I have been seeing since upgrading to Lion (10.7.3) and the latest version of Safari (5.1.3, I believe?). When browsing the web for a while (particularly, Flash heavy sites, I have noticed my computer's temperature getting hot and more beach balling starting to occur. The first time this happened, I opened Activity Monitor and noticed that Flash Player was using, almost, 900 MB of RAM (and I had less than 100 MB available). Other than Safari, I only had a couple of other applications open, neither of which were memory intensive. Quitting Safari gave me back a huge amount of memory, my temperatures, quickly, dropped back down to reasonable levels, and the performance lag went away. I never saw this kind of memory hogging under Snow Leopard. Is Flash Player this much of a nuisance under, either, Firefox or Chrome?Â
I have a 2010 MacBook Pro, 2.53 GHz, i5 with 4 GB of RAM.Â
Info: MacBook Pro (15-inch Mid 2010), Mac OS X (10.7.3)
intel iMac , 10.5.8 , suddenly USB ports stop seeing any devices ( flash memory stick , iPod etc ) connected to it , neither on keyboard nor on computer back panel . Finder or Disk Utility not showing this devices , but the devices could be seen using SytemProfiler . The same devices connected to another Mac computer are working fine .
I have a Black MacBook (Early 2008). I think that I still have the factory standard RAM sticks (I bought the Mac used from a friend). I noticed today that I am running on only one gig of RAM even though I have two gigs of memory.
I have a iMac DV G3/500 (Special Edition) from summer 2000. Anyway, I am using Mac OS 10.2.8. Recently, my start up disk's memory has gone done from 1.2 GB available free space to 668MB (currently). I haven't saved anything on this disk so I can not understand why this memory has dissappeared. I have also had icons on the start up menu disappear. Could someone please tell me how I can restore the missing memory?
I just bought a early 2009 MAC Pro and it came with 3GB of RAM, I ordered 3 2GB sticks of memory to replace the 3 1GB sticks that I had in there from Kingston. I turned off the unit, I popped the little levers and pulled the memory out of slot 1, 2, 3 and then replaced the memory with the new Kingston in slot 1, 2, 3
One of the sticks in is not working at all and I get the RED LED light no matter what slot I move that chip to. So I am running on 2 of the new Kingston memory chips.
Can I mix the memory and add the 1GB into slot 3 and 4 with slot 1 and 2 full of 2GB chips?
Also how to I run the memory utility again? I went to /system/Library/CoreServices/ and then I see the program Memory Slot Utility.app
How do I run this? I'm used to no spaces and I type ./then program name
I want to create a simple flash movie (I don't yet own or know how to use Adobe Flash). Pretty flowers in the background, inspirational music, passages from the Bible or something fading in an out... you know the schtick. Maybe convert it to a screen saver.
I'm trying to read news sites and my eye is distracted by things bouncing around in adverts. It's even worse when they're playing obnoxious sounds until you click the mute button in them.Therefore I just thought I'd let people know about this wonderful piece of software. I've seen it mentioned a few times here but even if this thread only helps a few people I think it'll be worth it:[URL]Not only does it hide these horrific insults to humanity (ok a bit strong perhaps), it actually prevents them loading, therefore your pages load quicker! And it's completely unobtrusive! If you want to watch flash file, simply click on in.
A friend of mine is having trouble playing flash videos on his 1.33 GHz PowerBook G4 (256MB of RAM). He has version 7 of flash player and is unable to upgrade to a newer version.
watch Youtube vids using H.264 MP4 codec instead of flash. As most of the videos I watch are recent uploads (last year or so) they have SQ and HQ H.264 version available. As Flash eats up system resources worse then anything I can think of at the moment, I am trying to find a way to force the videos to play in MP4 format. I know ClicktoFlash has this option for Safari, but I am trying to find out if there are any other ways to do this without user input (for playlists). I use YousableTubeFixURL for Chrome and Firefox which has the option to do this, but no matter what option I choose, it always plays using Flash. I know FF doesnt have a built in MP4 player, but I though I heard of a way to get VLC or Quicktime to play it.
After 4 years of no problems when I log onto Yahoo/AT&T email it says Flash is blocked-you must unblock Flash in an openmail app. I have reinstalled Flash to no avail. The email app seems to work fine. How do I make this message go away?
