Ssd 850 1TB

I want to know if a Samsung SSD 850 Pro 1 Terabyte will work on my HP Elite 8460p? I've heard that the laptop doesn't see it. Is there a solution to this? Thx vman

It will work fine. I question investing that kind of money in an older laptop but the drive will be recognized it is just not going to run to full potential as your system is SATA-II and the SSD is SATA-III. Still, it will work.

  • Is my "Samsung SSD 850 EVO 500GB" defective (or just incompatible with MacBookPro5,5 Yosemite 10.10.2 - 13 inch mid-2009)

    Is the Samsung 850 EVO not compatible with this MacBook Pro? Has anyone installed it and found it to work fine for a few months?
    Has anyone faced boot-partition corruptions, problems when installing Yosemite updates with this SSD - on reboot, SSD partition became unmountable for me after the installing Yosemite update 10.10.2 (14C1510).
    I am trying to understand whether
    mine happens to be a defective drive - in which case I have the option of getting a refund from seller and ordering a replacement (same make+model), OR
    I should return this one and go for a Crucial/OWC/other SSD
    Details:
    MacBookPro5,5 Yosemite 10.10.2
    Samsung SSD 850 EVO 500GB
    I purchased this drive and installed it in my MacBookPro about a week ago.
    Since then I have repeatedly run system-reported data corruptions on the SSD.
    One obvious sign of the corruption is that on powering-on the laptop, it will stall for a long time (5 to 30 minutes! - normally it would boot up in about 30 seconds) after the grey/black Apple-logo and status bar appear on the white-background boot-screen.
    Another way I see this is by running Disk Utility's 'verify disk' operation.. Reports serious errors and asks me to reboot in recovery-mode with Cmd-R to repair the partition.
    I have erased and re-installed the OS (Yosemite) several times on it already because sometimes the Recovery-Partition's Disk Utility cannot repair the errors - asks me to backup and erase+format. The repair operation does not always succeed *.
    This is happening often and without any pattern **.
    Several times on the latest install, I have booted up in single-user mode and run fsck -fy: till yesterday, this was still occasionally finding and successfully repairing issues (after which I run fsck a couple more times to confirm).
    Seems to be running fine today.
    * I am re-installing off of a TimeMachine backup.
    But I don't think that is causing the trouble: verify-disk on the original backup reports no errors, and even the computer itself passes "verify"/"fsck -fy" several times over before failing in the same way again after an hour or 2 of actual use.
    ** On one occasion, after an OS update (latest OS X security patches) succeeded and reboot completed, verify-disk again asked for the Cmd-R recovery-mode repair - which failed to repair the errors.
    Also, if I as much as launch the Yosemite installer while booted up, then even after quitting (without proceeding beyond the initial screen), the SSD fails completely again requiring to be erased. Happened twice with installers involved, but corruptions even without installers did happen.

    I loaded the Samsung 850 into my 2012 i5 Macbook Pro and it's been working well since I installed a few days ago.  The only concern I have is that on boot up I get a white screen for around 30 seconds before it begins the startup with the apple and progress bar.  That's odd, because when I installed an SSD on my older 2009 Macbook a few years ago that laptop booted up almost instantaneously when I pushed the power button. 
    I loaded the system on the SSD by cloning, rather than using Time Machine and it worked without a hitch.  Used Carbon Copy Cloner in trial mode after formatting the SSD with Disk Utilities.  Not sure if your problem may stem from using Time Machine.  The cloning apps will usually adjust the data on the new drive based on available space, so if your SSB is a different size than the original HDD, it would automatically correct.  Not sure about TIme Machine.
    I'll keep researching about the startup lag when I turn on my Macbook Pro with the 850.  Seems it should boot up right away with the SSD, but maybe it's because the 850 uses the new vertical stacking configuration.  That's the only thing I can think of that's different from the last SSD I installed in my old Macbook.

  • PROBOOK and SAMSUNG SSD 850 EVO DISK problems

    I have connected HP ProBook 470 G2 i7 processor with SAMSUNG SSD 850 EVO 500 GB via SATA3 to USB3 adapter (STLAB). SSD  disk is not detected by windows 7 (win explorer) neither by samsung magition SW.
    Is it possible to solve this.

    Does the drive show in Disk Management?
    Does it show as 'offline'? This sometimes happens with 'external' drives.
    If it is 'offline' just right click 'offline' and chose 'online' from the menu.
    Hope that helps.

  • Upgrade nMP late 2013 SSD to 1Tb.

    Any one know the part number for the 1TB SSD in the new Mac Pro (late 2013)? There are some available with a part number of MZ-KPU1T0T/0A2 made by Samsung. They are represented to work in both the nMP as well as late 2013 MacBook Pro Retina.

    Be sure you don't get stuck, that sounds a little dicey. We have not seen product announcements, but these parts are expected this year.

  • New imac with 256 ssd and 1TB HD want OS leopard and lion.

    I want my new imac to be able to boot into leopard or lion.  Should I partition the SSD or install the second OS on the second HD (1TB HD).  I have plenty of room on both since I don't tend to store much on the HDs.
    I haven't received the imac yet so I'm not sure if it will come preloaded with Lion.

    Well, if it comes with Lion preinstalled, then you will most likely not be able to boot into Snow Leopard. The point is that no Mac can boot an OS older than what it came with: notable exceptions would be Macs that are manufactured right around the time of a new OS release; in those cases, it may or may not be possible. It would depend on the machine and OS builds - you would have to ask Apple if it would be possible in your case.
    If you ordered a refurb from the Apple store, then when was it manufactured? And, they do show which OS is loaded on that page.

  • Can I partition 256gb ssd and 1tb hard drive to be split 50 / 50 for Mac OS and windows?

    I am going to buy a new iMac. The question is which storage option? If I get the 256GB ssd and the 1TB option, it appears the mac OS is pre installed on the ssd which is great.  I would then like to install windows 7 on the ssd using bootcamp, and partitioning the ssd to be half for mac and half windows.  I think this is the best thing to do... Correct? My main concern is then can I also split the 1 TB hard drive as well? Ideally I would like to split both drives 50 / 50, install the operating systems and software on the ssd and use the hard drive as general storage.  I have read mixed reports on the possibilities of this and would really appreciate your help and advice.  I am not that technical and would like to avoid using third party software, and stick to bootcamp if possible.
    Thanks all!

    I suggest you open Boot Camp Assistant and click on the button to print the documentation. Read it carefully before using BCA. BCA only creates the partition. It does not format it. That is done with the Windows installer at the beginning of the Windows installation.
    Although Windows can r/w NTFS volumes OS X can only read them. That means you can copy files from the Windows boot volume but not write files to it. If you need to move files to and from the Windows system you would use the data volume you will set up on the HDD. If you don't need to use files larger than 4 GBs in Windows then FAT32 is fine. Using ExFAT would only be advisable if you anticipate the need to handle files larger than the 4 GB limit of FAT32.

  • Upgrading from a 256GB SSD to 1TB SSD

    Hi,
    I recently purchased a 2014 a wonderful Mac Pro (Cylinder type)
    3.7GHz Quad-Core Intel Xeon E5 processor
    12GB 1866MHz DDR3 ECC memory
    Dual AMD FirePro D300
    with 2GB GDDR5 VRAM each
    256GB PCIe-based flash storage1
    Have formed a view for a number of reasons that I want to upgrade the HD to 1Tb SSD (rather than attach additional external storage).
    What is the best way to approach this upgrade without losing or having to reinstall the software already resident on the 256Gb SSD to be replaced.
    Please note I am a recent convert to the Apple platform so ignorance is assured.
    Cheers

    Since the first step is finding an SSD which will fit and work (as Cekari points out, your typical 2.5" SSD won't), this discussion might be of interest to you. It gives some idea of what's compatible with what.

  • From the SSD to 1TB HDD?

    Good morning I have an imac, 2010, with an SSD, and a 1 TB HDD, do you know which files and data you can pass the SSD hard drive, and do as you can perform this task?.
    I am interested in leaving the SSD only the applications and the OS, if it could.
    thanks

    Well that is much easier and is my best recommendation. Just take off the Service Plate on the back and swap them. To use the recovery disks the SSD has to be at least the same size as the original hard drive which is not so easy to afford with an SSD. This is a good video but the guy is not happy he had to do a clone of the old drive to the new. That is the way I always do it. If you need specific help with that let us know.

  • My mid 2012 Macbook Pro get a 4HDD/11/40000000: Sata(0,0).I just upgraded to a samsung 850 evo 500 gb ssd and i used super duper to clone it?

    I had no problems with my computer until someone told me to check apple's hardware test and now this code has me worried. Should I contact samsung about this and get a replacement drive or is it just apple doing it because its not from apple. One minor problem i had is when i shut the cover and then plug it in it sometimes crashes and gives me a kernel panic when i turn it back on. I just repaired my drive in disk utility and it hasn't helped now it crashes more!

  • Macbook Pro 96gb kingston SSD + 1TB WD Scorpion Blue: Harddrive Issues

    Hi,
    I would like to ask to following thing:
    I installed the 96gb kingston SSD & the 1tb WD Scorpion Blue in my macbook pro (Mid-2008 model).
    I use the 1tb as storage drive so my data gets moved to this drive. Now the following thing is happening:
    When I try to play a file in itunes (.m4a audio file for example) the file gets loaded but suddenly stops playing. Same when I move large amounts of data to the hard drive it suddenly stops, the beachball pops up wait 10/15seconds and then continues.
    Is there a way this can be fixed or is this a drive error? Should I check it with drive genius?
    I don't have them installed in any raid or something like that. I just plugged them in and installed Leopard 10.6.7.
    Greetings,
    Maxime

    I have to add that both drives are formatted with Journaled HFS+

  • SSD won't boot after using Win 7 recovery discs

    Hi, I bought a Samsung SSD 850 EVO 1TB for my HP Pavilion dv7-4012eg which had a 1TB hard drive (same size).
    I took off the original hard drive and attached the SSD on the primary slot, leaving the original hard drive unattached until I configure everything with the new one not to confuse things.
    I had burned the 6 recovery DVDs from my HP and had used them before on the original hard drive without any problems.
    So I did the procure I am used to, and after the 6 DVDs the recovery said the laptop was going to restart to install and configure the OS. But when I restart it says there's no bootable device, that I should insert one.
    I inserted the DVDs again and went through the whole process again just in case, but still got the same no bootable device message.
    I installed Ubuntu and it was very successful, and I can boot Ubuntu fine. When I try to boot the Windows partition now it starts something but says something like that the installation was not finished.
    I also have my Windows 7 Home Premium 64-bit OA HP license readable under my laptop, so I tried to download the Win7 from the Microsoft Software Recovery but it says to contact HP because the Windows was pre-installed on my laptop.
    What can I do? Any ideas why I got the no bootable device error after going through the 6 recovery DVDs?
    Cheers.

    Hi @jessymeyer ,
    Welcome to the HP Forums!
    It is a  superb  place to find answers and tips!
    For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
    I understand that you are replacing the hard drive in your Pavilion dv7-4012e with a SSD.  You were able to do the recovery but when it went to reboot you got the error no bootable device found.
    Did you change the boot order in the bios back to the HDD first?
    You could also try restoring the defaults in the bios so that it will scan for hardware and find the new hard drive.
    Good Luck!

  • Any ideas on the best Config for RAID-0 on the Precision M6800 using SSD's (and the mSATA slot)

    Hi,  I have an M6800 on order that has a single 500GB 7200RPM hard drive.  I am going to upgrade the storage the day it arrives (removing the 500GB drive and not utilizing it at all).  I plan on setting up an SSD RAID-0 array and want to take advantage of the mSATA slot if possible. 
    I thought of using the 2TB 2.5" Seagate/Samsung Momentus SpinPoint ST2000LM003 hard drive for storing unused vhd\vhdx files as well as video and photos,  then using an SSD RAID array for the OS, Applications, Data and any active vhd's. 
    Is it possible to set up RAID-0 using the mSATA SSD slot and the primary internal hard drive slot?  I want to use those 2 drive connectors so I can still use the 2TB 2.4" regular notebook hard drive without removing the Blu-Ray Writer?  I plan to write video to Blu-Ray discs that will be stored on the internal 2TB drive, so removing the optical drive is something I want to avoid.
    As a general question, Is there any advantage to using RAID with SSD's, or would a single 1TB mSATA SSD in the mSATA slot be nearly as fast in real world use as a 2 disk SSD RAID?  Would I have a noticibly quicker boot time and application load time if using SSD RAID?  I know the speed test specs show large increase in performance, but will the computer really run a lot faster with 2 x 500GB SSD in RAID-0 as opposed to getting a single 1TB SSD card for the mSATA slot?
    I was planning on getting the Samsung Evo 840 SSD 2.5" drive and the matching Evo 840 mSATA card.  There is a Samsung 850 series drive, but it is only available in 2.5" (mSATA is not available in the 850 as far as I can  tell).
    Please suggest the best solution that is compatible with the M6800 or provide any information that might help.
    Thanks

    Hi Ential, 
    Thanks for the info, I thought my question would go unanswered forever.  I posted the question in January, and I have since set up the computer.  Below I will detail my research and the configurations of drives that I have used on my M6800 since the time I posted the question you answered.  Perhaps the results of my research and testing might help you. 
    I originally I bought the same exact model SSD's that Dell sells with the computer thru their website;    the LiteOn 512GB drives (mSata & SATA),  I configured them in RAID-0.  The LiteOn drives are sold under the brand name Plextor,  I found the proper model numbers by looking at the SSD drive firmware upgrade file from the Dell support website.
    From what I understood,  my RAID-0 drive consisting of the 2 LiteOn drives had impressive performance using the AS SSD benchmark program,  I was getting performance scores over 1600 back in February.
    I have since changed to the Samsung EVO 850 1TB drives and again created a RAID-0 drive,  one SATA drive and one mSata drive totaling 2TB.  This drive array is getting AS SSD performance scores over 1900.  I contacted Samsung to get some advice on the configuration of the drives and I got some interesting advice that seemed to help a lot:
    Samsung told me to leave 200GB of the drives (100GB each) unallocated when I partitioned the drives,  this is generally referred to as "overprovisioning" (which you probably knew already).  I initially thought that overprovisioning could only be configured by the Samsung Magician software and a special process needed to take place to tell the firmware to utilize a specific amount of drive space for overprovisioninng.  The Samsung support agent told me that the Samsung SSD firmware (on both mSata and SSD) automatically uses any unallocated space as overprovisioned space (they are basically the same thing to the drive firmware) and it increases performance in a very  noticible way when you have sustained use of the drive and/or durinng the time in between the TRIM process (garbage collection).  The unallocated space is used by  the firmware to write data to while blocks of data are awaiting internal wiping initiated by the TRIM process.
    Since I have 200GB of unallocated space,  I am able to have more sustained deletion and writing of data between TRIM/Garbage Collection runnninng than I would ever utilize without affecting the performance of the drive.  Basically most SSD drives have performance decrease throughout  the day until the TRIM process is completed by the drives firmware,  so Samsung instructed me to leave at least 10% of the drive space unallocated to limit that problem.  Smaller drives likely need a higher percentage of space unallocated as compared to larger drives since the daily amount of read/write operations is typically the same regardless of drive size.   The amount  of space left unallocated/overprovisioned is based upon the amount of read/write operations done on any given drive,  not based on the size of the drive itself.  If you run drive intensive applications, you would then want to overprovision more GB of drive space,  if you have light use of the drive then you can overprovision/unallocate less GB of drive space (all of the configuration info regarding overprovisioning and TRIM was given to me by a Samsung specialist over the telephone - I called their tech support phone number and got a storage specialist to talk to me). 
    I will look into the SATA version on the optical bay,  I never thought about that with this computer.  My prior computer was a Dell XPS 17 3D (L702X) notebook which had 2 internal 2.5" SATA,  in which I installed an optical bay drive.  On that specific computer the optical bay was technically an SATA 3,  but due to design constraints it couldnt run at that speed since there was voltage leakage across some pathways in the chipset when the optical bay has read-write throughput that is typical of a hard drive (as opposed to much less data transfer typically seen on an optical drive).  The M6800 can be factory configured with an optical bay hard drive, so I suspect it can support one properly.  The XPS 17 was not available with an optical bay drive as an OEM configuration from Dell,  so it couldnt be expected to properly support one.  The design issue with the voltage leak across the chipset pathways on the XPS 17 was known by Dell,  but due to the low bandwidth of an optical drive, the problem never occured with any of the factory OEM configurations.
    It is possible that the optical bay  hard drive offered by Dell (the exact OEM Drive installed by Dell) could have an internal limitation to SATA 2 due to a similar design limitation.  It would not be surprising if an SATA channel designed for optical drives had SATA 2 speed since I suspect there is no SATA Optical drives that could use more than 3GB/s of data anyway. 
    I purchased 2 of the 2TB 2.5" hard drives that Dell uses for OEM configurations for this computer,  they are Samsung 5400 RPM drives.  I have one in a 2.5" internal bay and the other in the optical bay - I converted my Blu Ray Recorder/Writer drive to an external drive.  I will do some extended time speed tests on the optical bay drive to see if its performance matches the internal drive (which  is the same exact model drive - I have 2 of the same Seagate 2TB drives installed with the same firmware).
    I use the pair of 2TB drives to store .vhd and .vhdx drives for test platforms for Hyper-V machines.  The virtualized servers with high hard drive utilization get moved to the SSD RAID-0 array,  the rest are stored on the 4TB rotational drives. 
    If you have any questions or comments for me,  please let me know.  I will see what info I can find on the optical bay SATA revision for this notebook,  I am very curious to find out if it is in fact SATA 2.  I will let you know what my test results are,  I will try to use the AS SSD benchmark program,  I believe it will work with rotational drives,  otherwise I will find another benchmark utility - do you have a recommendation on which to use?
    Thanks again for your info and for pointing out the possible limitation of the optical bay..

    Hi,
    The HP e9280t only has SATA II ports so any SATA III SSD will not reach it's full performance potential.  A more cost effective alternative is to look at the Samsung 840 EVO which is highly rated in many of the PC industry magazines. I know the Samsung 840 EVO will work in your PC.  Look at a 250GB or larger model.

  • Satellite L50-B-2C8 - new SSD is not recognized in BIOS settings

    Hello,
    I just bought a new notebook Toshiba Satellite L50-B-2C8 and I also bought Samsung SSD 850 evo 250GB.
    When I try to install the SSD drive instead my HDD the BIOS show "none" in Category SSD/HDD (BIOS not recognize the SSD).
    Please help me.
    My bios version is : 2.00v
    *** someone told me that I need to downgrade my BIOS version to 1.2v, and then the BIOS recognize the SSD drive, so maybe someone here can send me a download link to the 1.2 version of my model L50-B-2C8 .
    Thanks

    From my point of few there is no reason why early BIOS version should recognize the SSD drive and the newest BIOS version doesnt
    But BIOS v1.2 for Satellite L50-B-2C8 PSKTQE series does not exists the v2.0 (at this time) is the latest version and older BIOS versions are not available for this series.
    Furthermore I guess you will need slimply check different SSD drive it could be possible that other SSD drive would be recongized properly.
    By the way: Im owner of Evo 850 SSD drive and as far as I can remember I had to update the SSD drive firmware to use it properly in connection with my other notebook (not Toshiba unit)
    problem solved tnx
