Life wrote on the SSD Plus Ultra

Just curious if anyone can shed some light on the SMART for these readers info when it is the host entries. I'm just trying to follow my writing that I'm using two of the drives 256 GB in a raid for a type of home environment with hyper-v server so I can study for my microsoft certifications, and I am concerned by wrote several operating systems running at the same time can cause.

When I look at the data in crystal disk info, the numbers are huge, decimal numbers are 990570319 and 997894294 respectively and compared to my other non-sandisk SSD and my sandisk 128 GB extreme in my laptop (would have been again with an extreme but the price was unbeatable for the ultras ability) these numbers are huge. For example, my extreme of 128 GB in my laptop is currently in 1147.

They measure using different units? I guess that's the question, and I know that the controllers are all two made by different companies on the disks, so I'm sure that could have something to do with it, but anyone can shed light on the ultras? Info is rather mixed, because they are so new. Thanks for the help and your time.

Edited to add a screenshot:

The Extreme SSD uses a Sandforce controller and the attribute of SMART for life entries is displayed in GB. The Ultra Plus uses a MArvell controller and if I remember well for the indicated number of Marvell 1015669923 is the total number of write operations issed by the host. Each write operation is 512bytes. Use the following method to get the total GB wrote.

Total number of operations x writing 512 = total number of bytes written

1015669923 x 512 = 520,023,000,576

Total number of bytes written / 1 024 = total number of kb writes

520,023,000,576 / 1 024 = 507,834,961

Total number of written kb / 1 024 = total number of MB written

507,834,961 / 1 024 = 495 932

Total number of written Mo / 1 024 = total number of GB wrote

495 932 / 1 024 = 484 GB

  • Very low yield, 256GB SSD Sandisk Ultra plus

    I just installed a 256 GB SSD Ultra + on my Samsung NC110 Netbook with chipset Intel NM10, tweaking all active (TRIM, AHCI, etc.) and the SATA 3 mode works as expected.

    The SSD is pretty slow: with the AS SSD benchmark tool I get 243 MB/s read and 214 MB/s write, while I was expecting something like 400 MB/s.

    Anyone had similar low values with the same Intel NM10 chipset?

  • Passage to the SSD for late 2008 MacBook for editing video: Samsung 850EVO or Pro?

    Hello

    There are a lot of things out there on the upgrade the bowels of SSD and I narrowed my choice to Samsung 850 Evo or Pro, but there are some details that I found not covered elsewhere. The idea is to give to my MacBook Pro a few years in addition to be able to edit HD video (currently, it slows to a halt). I'm also upgrading to 8 GB of RAM.

    My questions are: both the EVO 850 and 850 Pro actually work in my model, old as it is?

    I would notice the difference between the two while editing video, taking into account the difference and compatibility issues/limitations of price? (Limits of SATA would effectively slow the levels of the EVO Pro?)

    If/when I get ahead, it is advisable to keep my entire modification on a with the main files external HARD drive, or should I keep makes it / cache on the SSD drive?

    Here are my specs:

    MacBook Pro (15 inch, late 2008)

    2.4 GHz Intel Core 2 Duo processor

    4 GB 1067 MHz DDR3 memory

    Macintosh HD boot disk

    NVIDIA GeForce 9400 M 256 MB graphics card

    Running OS X El Capitan 10.11.5.

    Please keep in mind, I am a techno-idiot and 90% of the above words I learned again in the last two days!

    Thanks in anticipation,

    Graeme.

    Probably not.  You willing MBP of SATA2 connectivity and the full potential of each SSD not happen.

    If/when I get ahead, it is advisable to keep my entire modification on a with the main files external HARD drive, or should I keep makes it / cache on the SSD drive?

    It's your choice.  If the capacity of SSDS is quite large, personally, I like to keep all data on a single disc, but maybe it's not convenient.

  • Avast! Writes to the SSD much antivirus software during scan

    Hi guys,.

    I have installed avast! Antivirus on my Mac, do not protect my Mac specifically, but to keep it to pass on the Windows malware to other computers or on my Windows partition. When the full analysis of the system, I notice that he reads a lot of data in the player (that I know), but it saves up to 40 GB of data in the SSD at the end of the analysis! I know writing excessively on the SSD can shorten their life (although I tried to calculate its expected service life using my daily writing, and I should have at least another 10 years of use, which is more than enough).

    My point being, why is avast! write on the disk so during a scan? Is it caused by a heuristic analysis or something? I don't want to put unnecessary pressure on my SSD, even though I know that Apple SSD are generally pretty durable.

    Thank you.

    Note: Please don't give me a conference on the installation of antivirus software on Mac - I know that this is not strictly necessary but I explain why I use it at the beginning of my post.

    Your windows contacts can take care of themselves. He has no need of you to your Mac protecting wear.

    Your Mac is already well protected without that avast garbage making it unstable.

  • Old Compaq Evo N1020V, replace the hard drive on the SSD

    Hello
    I wanted to extend the life of my old Compaq Evo N1020V Intel P4. I bought a Transcend SSD TS32GSSD25-m, connected to the computer, I have updated the BIOS to the latest version available F.0B January 24, 2007. Unfortunately, when the computer starts the message: 0200: failure fixed disk 0
    Is it possible to connect the SSD drive to the old computer?

    I see that now.

    You initialize the drive using the FDISK utility? If it is not initialized it would not even necessarily considered gift.

    Installation of an operating system on an SSD, this isn't the same as it is with an electromagnetic drive legacy.  It is a little involved with an old SSD OCZ Vertex and enough conversely simple with a Corsair SSD upgrade kit. I own both. The upgrade of the Corsair was as simple as with the SATA supplied to the usb connector and software cloning with that also it was delivered.

    To do a bit of research I saw that there is not much in material information facility available on the web for this particular SSD. Maybe the transcend technical support would have been a better place to look for info on the installation. Transcend would have supported their product. The post that is marked as the solution is not correct. It is as you say a disc SSD PATA. It must have worked. the problem seems to be more a problem installation or a failing Transcend SSD drive. return the drive for a replacement and try again.

  • HP 350 G2: 350 g2 hdd upgrade (for the SSD)

    Hello

    Does anyone has seen a good quality video or photographs explaining the withdrawal of hard drive to a G2 of 350 HP.

    Seen manul user and/or maintenance but the details about the kidnapping are unclear.

    Ken Maitland

    Hi, Ken:

    I have the 350 G1 and when I first looked at it, I didn't have no idea how out the hard drive.

    I had never seen a montage like that in my life before.

    I took a glance at your manual, and it is exactly the same as the G1.

    I did not remove the connector from the hard drive of the PC.

    What I did was gently upward on the hard drive to the connector on the hard drive.

    Then he lifted right out.

    I then carefully unplug the connector on the hard drive, removed the rubber from the HARD drive support, put it on the SSD and installed my new Intel SSD. I put the connector back on until I pushed the rubber mount in the drive Bay.  There are 4 feathers on the rubber mount coming in the where the screw-drive would go.

    I searched in vain for you tube videos, etc, so I went just for her.

  • If I use the SSD to initiate the operating system and a hard disk of data what exactly will be the benefit of this end?

    Hello

    I would like to know if I use the SSD drive for the operating system boot and a hard drive for data. What will be the benefit of this effect,

    I know that SSDS starts much more quickly and reads and writes data faster.

    When I use the SSD for OS then my only wil advantage so I have faster from the OS, not more than

    but the reading and writing data wil either by the hard drive so I wil not use all the benefits of the SSD, data wil be read and written by hard drive!

    Am I right or wrong?

    SSD benefits for most of the time of loading, and it is for all software. If you install Windows on a SSD and return to a HARD drive after a few weeks you will certainly appreciate the value of an SSD, just for the

    only the loading.

    While startup in Windows is the most obvious, the Windows advantage is usually a bit snappier

    on an SSD.

    An SSD expected to also help in many programs such as Photoshop, video editing, the processing speeds

    or CAD, due to data being created during the writing of these programs.

    I think the reads and writes more visible with large files.

    All my programs are on the SSD, but my games are on the HARD disk.

    Games to load a large number of data and will load faster on an SSD, but it's still a few seconds.

    and as games use a lot of Go, it is not really profitable to keep (150 +) on an SSD.

    -J' I keep most of my data, except the music (to save space) in my user folder, but haven't really

    noticed a difference in speed when opening a data file, such as a Word, PDF, images, or similar

    'small' files from the HARD drive.
    -I wouldn't take an SSD less 120 GB. Try to run Windows on a 60GB translate too

    stuffing autour with management of data between the SSD and HDD. In particular, as it should be

    keep 20% an SSD free to allow the two "garbage collection" and deliver a load of

    cells of extra memory to extend the life of the DSS (data gets moved to empty cells when the cells die).

    There is also a noticeable difference between the speeds of SATA2 and SATA 3 controller, so if your motherboard uses the SATA2 more the advantage of an SSD is not as great as with SATA3.

    In addition, the new SATA3 SSD controllers are faster than those of two years ago.

    SSD is a big enough topic. There are many items in the wild that may be useful.

  • Workstation transmit orders ATA TRIM in Windows 7 for the SSD to Win7 host OS?

    Does anyone know if Workstation will pass by the guest operating system commands ATA TRIM to support the comments of the OS (win7 win7 head invited in my case with an OCZ vertex SSD running), or if its even possible to configure it somehow?

    Maybe a good future feature, if not as the SSDS become more common... I'm not avoiding running VMs on a SSD until I see this support.

    Hello

    No, it is not as a guest that OS totally ignores the system disk used in the host operating system.

    In all honesty, it's a good thing because it means that you can take your VM and move it to another host without any problem.

    Workstation support this in the future with the host operating system will add that the desired cut orders?

    I don't know if it is possible even to do and VMware is not comment on what is or isn't on the design table, so I doubt you will get answer to this question.

    What is the use case you want to have the taken trim command support? Save life of your SSD? Even without filling its going to have an MTBF that is bigger than your normal SATA/IDE drives.

  • What is the life expectancy of the battery in the pen of Apple? Can it be replaced or do I need to buy another pen?

    What is the life expectancy of the Apple pencil? The battery can be replaced or do I need to buy a new stylus?

    According to iFixit (of https://www.ifixit.com/Teardown/Apple+Pencil+Teardown/52955 )

    • The pencil is clearly not intended to be opened or repaired; You can't get inside without destroying the device.
    • The layers of plastic and metal holding the interior components are impossible to remove without grinding.
    • The battery enough for a 12 hour race, is impossible to replace, which gives the device a limited life expectancy.

  • Organizing files on the SSD and HDD

    Hello

    I have a 250 GB SSD and a 1 TB HARD drive and am looking for the best way to structure my work FCPX (the SSD is too small to store everything). The application is installed on the SSD, which I suppose is the best for performance. I recently discovered the properties of the library menu and set it to store media and backups on my HARD drive, but the Cache on my SSD. I don't really know if it's the best - any help would be greatly appreciated. Thank you!

  • Increase the performance of MAC with the SSD upgrade

    I have a 21.5-inch iMac model 14.1 (end 2013) with 8 GB of memory and a 1 TB drive. On this, I use some applications in memory such as Adobe CS 5.5 and VMWare Fusion 8.1.1. I have Applecare on the machine until September 2017. I often find myself running out of memory. My goto solution would be to increase the memory and replace the hard drive with an SSD. I fear, however, that this cancels my Applecare. My research indicates that while that frowned upon, I can upgrade my memory and keep my Applecare as long as it is done by an authorized by Apple, but if I do the SSD I'm out of luck for the installed components. My thought is that I can get an external SSD and move the ' WIndows 10' VM (s), as well as expand and move the swapfiles for the SSD system.»

    My questions are am I right about the Applecare and warranty and I plan to use an external SSD to accelerate performance and ease the work of memory constraints?

    I have a Macbook Air in 2010 and also a 2008 iMac - both with only 4 GB of memory (you have twice as much), both running El Capitan and the two with SSD - and perform very well. The 2008 iMac used to have a rotating disc which has recently failed, with the replacement of SSD, it is a remarkable transformation with the new SSD, it seems very quickly for me. Both have Photoshop CS4, which is not used much more, but they run this software very well, as well as MS Office 2011 and other programs such as Mail, Safari, Firefox, etc. (Firefox + Photoshop together put a noticeable load on machines, in fact, but while I sometimes hear the fans come on the Macbook Air, it maintains not up very well) No slowdown) You'll be in great shape with a SSD for your newer computer. These old machines that I use have Core 2 Duo CPUs, chips relatively slow, but they seem very quickly with the SSD.

    You will need to check with Apple directly on your AppleCare and so that would be affected. I don't know that anyone is not Apple should trust this question.
