Corsair SSD and boot speed

Hey all,
Rebuilt my system last week, specs are in the sig, and the initial boot times with the corsair was 7-8 seconds.  However, after a reboot a couple days ago, my boot times are now 17-20 seconds.  Nothing on my system has changed.
I even commented out the non SSD mount points I had (additional 2TB drive) in fstab, that didn't help.
The drives are formatted with GPT and I am booting via mbr.  I ran fstrim, didn't help, shaved off ~1 second from the boot time.
Here are my benchmarks:
hdparm:
hdparm -Tt /dev/sda
/dev/sda:
Timing cached reads: 9804 MB in 2.00 seconds = 4906.19 MB/sec
Timing buffered disk reads: 1056 MB in 3.00 seconds = 351.46 MB/sec
and dd:
write:
dd if=/dev/zero of=tempfile bs=1M count=1024 conv=fdatasync,notrunc
1024+0 records in
1024+0 records out

what other info can I look at on my system?  what other info can I provide here to help?

I am going to disable gdm and see how long I get to go from grub to the cli login, this should rule out the DE, I would assume.
EDIT:
boot time from grub to CLI login = 6 seconds
boot time from grub to cinnamon login = 16 seconds
So why would it take cinnamon 10 seconds to get to login screen?

  • [SOLVED] SSD and boot problem

    I haven't encountered this problem with any other drive I've put in there, so I'm guessing it must be SSD-related. Has anyone else experienced something similar, and could you point me in the right direction? Thanks.

    Yes, I do. Healthy drives don't timeout on simple DMA initialization requests.

  • SSD and Boot Camp

    Hello everyone.
    I am planning on installing an SSD in my MacBook Pro 2009 13".
    I have a Windows 7 Boot Camp Partition, and have no problem reinstalling Windows and OS X Lion after I get the SSD.
    But I read somewhere on the WWW that in some cases Boot Camp doesn't play nicely with SSD's? Can anyone advise me on an SSD that will work with Boot Camp? Are there any other issues i should be aware of?
    Thanks,

    When? what model? what firmware?
    All SSDs are changing and some Macs had trouble. With Apple SSD. With SATA3. With firmware. With updating firmware.
    Generic? All SSDs? No.
    OWC specializes in Mac (they are MacSales) and has reputation for top tier SSD and tested controller firmware

    An Intel 520 is also top tier. Crucial M4. Read reviews.
    But a blanket generic all/northing...

  • Fresh install new SSD and boot from USB problem.

    Hi!<br><br>I have a HP pavilion g6 -2031so that i just wanted to change the HD to a SSD. I got the filés setup on a USB stick using the Windows tool.<br><br>I cant really enter bios properly. I press Esc on start, and enter bios. BUT i can barely change anything! So The installation won't even start, it's just a blinking underline in the corner.

    Hello Ericwei, welcome to the HP Forums.
    I see that you're trying to setup a newly installed SSD and install Windows on it with your recovery flash driver. I will try to assist you with this.
    It seems like you've encountered and issue getting into the BIOS to set the booth order?
    When you try entering the BIOS, what difficulties are you having? Do you get any error messages?
    You do mention that you're able to enter the BIOS but you can't do anything. Could you clarify what you mean by this. Are things greyed out? are you getting errors? Is nothing happening when your trying to navigate the BIOS?
    You should be able to navigate in the BIOS to setup the Boot Order, to have the first be the usb flash drive. If that's done, then upon restart the notebook should be booting from there.
    If this is set and it is not booting from the flash drive, what is it doing? Are you getting errors?
    Please reply with as much detail as you can on the issue, with answer to the questions. This will allow me to assess the issue for you and provide further steps.
    Thank you for posting on the HP Forums.

  • How much Ram SSD and CPU speed should I get

    Hi,
    A friend of mine wants to buy a 2014 13" Retina MacBook Pro.  He typically changes his computer every three years or so.  He asked me if he should go for the 8GB RAM that come standard or upgrade to 16 GB.  He also wasn't sure if he should get the 512 GB or the 256 GB model.  Also, he wasn't sure if he should upgrade the CPU to i7.
    He is not a gamer, but he is a heavy internet, and MS Office user.  He uses iMovie occasionally for video editing.  He is thinking to upgrade to Final Cut Pro.  He also wants to uses Parallel and Boot Camp for windows 8.1 as some Window Apps requires full access to the video and CPU.
    Please advise me what should my advise be to him?
    Thank you.
    Tareq

    It is not difficult to give an opinion, but that is all it would be. No one can project performance of a specific configuration's usage in advance.
    To state the obvious, more power is better. It depends on how much one is willing to spend for "better" performance.
    Based on what you described, I would buy as much as I could afford.

  • Can I have iTunes music on my SSD and an external drive? How will this affect syncing to iOS devices?

    I don't have space to keep my entire iTunes library on my SSD. Currently I have my iTunes library split as follows:
    SSD: Contains a subset of music, apps, books, etc. New items usually get added here.
    External HD: Contains all of my music and iTunes media (including apps... so many apps). It's usually missing the most recent items added, due to the fact I don't plug it in so often.
    I ran into a problem maintaining these two libraries earlier while syncing my iPhone. When I tried to sync the iPhone with the SSD library, it would delete apps off of my phone because they weren't contained in the iTunes library there, even though I had the same base .itl file for both the SSD and the external libraries.
    What I want to do is set it up so that I maintain a core of music on my SSD and the stuff I don't listen to as often on my external hard drive. I also want to keep all the space hogs (movies, apps, etc) on the external as well. However, I want this to appear as one seamless iTunes library and I DON'T EVER WANT ANYTHING DELETED FROM MY PHONE WHEN I SYNC IT. I want to be able to sync my phone without worrying that apps will be deleted and I'll have to restore them from iCloud and reset all the settings, sign in, etc. Right now I am backing up to iCloud, but my understanding is that iTunes will still delete things from my phone if they are not available in the library.
    My question: How do I accomplish this? I have a lot of metadata in my iTunes library that I don't want to lose (playcounts, ratings, etc).
    I currently have this:   SSD: .itl file pointing to music on the SSD, a mixture of iTunes media (some that I want easily accessible, some I don't)
                                      External drive: .itl file pointing to music on the external drive, all of my iTunes media (except for anything I may have added to the SSD)
    I think I need this:       SSD: .itl file pointing to music on the SSD and the external, music that I listen to often
                                     External drive: music that I don't listen to often, things that take up a lot of space
    My thought process is that I will need to somehow move music from the external to the SSD while maintaining the pointers so that iTunes knows where they are. For this I have unchecked "Keep iTunes Media Folder Organized" and "Copy Files to iTunes Media Folder When Adding To Library," and to maintain the pointers and move the songs, I'm thinking of using Doug's Applescripts for "Relocate Selected:" http://dougscripts.com/itunes/scripts/ss.php?sp=relocateselected
    Once I have the songs split across these drives, I'm going to copy the .itl file from the external to the SSD and boot it up to see if it works.
    Two things: 1.) Will this approach work? Can I maintain my library across separate drives this way and have it be seamless? I understand I won't be able to access the media on my external hard drive when it is not plugged in (duh), but...
    2.) Will it affect syncing? When my external isn't plugged in, will iTunes try and delete things from my iPhone? It should still be able to "see" them, it just won't be able to access them. Will I have to turn off syncing apps while syncing with my external device unplugged?
    Thanks very much for any help and insight! It is greatly appreciated as I deal with limited storage space and an expanding iTunes library.

    This is all just a partial answer since details will depend upon how you want to do it.

    You'll need to get it all onto one iTunes collection on your Mac Pro, then sync the devices to that.  iTunes only lets you transfer purchases from a device, otherwise you have to use third party software.
    I guess you could also look into getting iTunes Match.

  • T520 with Kingston SSD and OS Win XP Sp3 - Unmountabl​e boot device

    Hello everybody,
    I have a problem with the combination of our Lenovo T520 and a Kingston SSD. The last laptop we have ordered no SSD seems to be working with the laptop. I install normally WIn Xp with SP3 the installation work very well but when I begin to install new drivers and make a restart Blue Screen with unmountable boot device. Ive tried also an Corsair SSD it results with the same effect. Do have any idea what else I can do? I've also made an bios update but that also doesn't worked very well. Do you have any other Ideas that i can try to have a better result.
    Best Regards
    ITRUNGIS 

    Same problem here, spent half the day figuring out what was causing this, now I find another victim. Here's what fixed it for me: Restart WinXP with your ext. monitor connected, login to admin acct, go to "Start" menu>Control Panels>Printers and Other Hardware>NVIDIA Control Panel. Expand the Display folder on the left side and select "Set up multiple displays", then select the "Use only one display" radio button and make sure your laptop display is entered in the "Select the display you would like to use." box. Approve the changes and now it should restart without the ext. monitor connected.

  • Installing / Booting Between a SSD and HD

    I recently purchase a Toshiba P500 series computer with a 64GB SSD and a 500 GB HD.
    I want to install Microsoft Office and other apps were I am not interested in the speed the SSD provides ; I want to conserve the SSD disk space.
    I understand how to do the "basics" of the install; when the install utility starts choose custom and select the hard drive letter and file I want to install the program in.
    What I do not understand is this: I the SSD to be the boot drive, which is fine I want that. How do I get the SSD drive to recognize the software on the HD??
    Also, Toshiba installed a bunch of stuff I on the SSD I want on the HD. Can you use some transfer ulitity to in Windows 7 to move the files?
    Thanks

    I can offer a little assistance here.  When you install an app to another dive an icon is created in the start menu and perhaps the desktop.  These icons are links to the program startup *.exe file.  If you right click the icon you can place this link in the taskbar to start with one click from there.  When you do a custom install to the second hard drive and look at the drive contents you will see a folder that says Program Files.
    A word of caution with Office 2007 and 2010.  Both can be installed in 32bit or 64bit.  Microsoft recommends that all the office productivity tools be installed in 32bit.  This info comes directly from the Microsoft TechNet download web site for those who wish to pick on this issue.
    Some of the Toshiba Utilities can be downloaded from their web site.  They (installers) may also be on the recovery disks.
    Some one else can provide advice on this.

  • Upgrading my intel iMac to internal SSD and running 1TB external drive from firewire 800 for mass storage while still using a second external drive for backups...my goal-speed with a SSD, to still have 1TB of room for everything i have now..possible?

    I seem to kill HD's every two years...the last two i've installed were WD Caviar Black 1TB 7200rpm 3.5" drives. The speed gains over  stock drives have been remarkable. I don't blame the drives for the failures, my machines are up and running 16 hours a day, every day, year round. They die from 'mileage' so to speak...i assume...there's no viral acvtivity or questionable downloads to gunk things up...just lots of work.
    I have my third new drive ready to install in my intel based iMac...but i've had a thought...I want to install a SSD in my iMac for the speed gain (and recent price drops)...for standard storage i want to use this new WD Caviar Black 1TB in an external drive bay and connect via firewire 800 for storing everything except the OS and my most commonly used software...am i crazy? will the firewire 800 external drive negate the speed gained with an internal SSD??
    I have four iMacs in my office, and one at home. I buy second hand and install new drives and boost memory. I'm going to do this on my 'home' machine...if it works out well i want to upgrade the other three this way...but first i need to know if i'm just dreaming, or will it really make a difference? or even possible??
    Thanks!

    The SSD gives great bootup and Application launch speed. I think it also speeds up the video rendering a bit, I do all that on the SSD and then move the finished project to the external drives. As far as the speed for the external drives they are quick enough for viewing video and the file transfer rate is good. I had initially put the SSD into an external cradle (FW800) and the system was faster than on the internal drive. I only got a 1.5GBs SATA drive, perhaps yours could benefit from the 3GBs. I know the 6GBs would be too fast and costs a lot more, even the MacPros need special hookups to make use of the 6GBs.

  • How to use ssd as boot drive and hdd as storage on a macbook pro 13

    Does anyone know how to use SSD as boot drive and have HDD in optical bay as storage on a Macbook pro 13. I mean in that both drives work as one . by formatting using mac software . I would like to run all programs and OS but would love to have my downloads and useless data on run on my 1tb 5400rpm hdd without me have to manual send it there..

    Each drive mounts as a separate volume. There is no convenient way to make them look like one contiguous volume.*
    Franky, with an hdd and a ssd I would recommend you put your home dir on the hdd and leave the ssd for the OS and your key applications.  It's relatively easy to do and I think better than moving only portions of your stuff.

  • How do you run to Drives on the same screen. I installed a ssd and a hhd to my mac but i can only view the content of the drive only if i boot of that drive. Im try to have my ssd for fast boots and hhd for my music,movies etc. Please help.

    I installed a samsung 840 pro SSD to my primary slot and relocated my 1.5 TB HDD to a data double where my optical drive was. I transfered my apps and Mac OS X to my SSD for fast boots and all my itunes movies, music, Iphoto etc to my HDD. I rebooted off my SSD then seen all the data on my HHD itunes movies, music, iphotos etc i cannot view on my SSD. So my question is how do you view all the content on both the ssd and hdd on the same screen with having to boot off one or the other?

    No, what I'm saying is that once you boot into OSX, you should be able to see both drives listed.  If you don't then either OSX is hiding the other drive because it sees it as a boot drive and is trying to protect the contents from novice users or there's another problem.  If it's the first thing (i.e. it's a protection thing), then your only option would be to boot into the old drive, copy off all your personal data to an external backup drive, then reboot into the SSD and go into Disk Utilities and wipe/reformat the second drive so that you can see it as a regular secondary drive.  Then when you see it as that, you can copy your data back to it.
    Be carefull poking around in Disk Utility as you can easily lose your data.  It's possible the Mac just isn't mounting that second drive because it sees it as another boot drive.  Whatever you do, don't accidentally erase it without getting a copy of your data off of it because you obviously don't have that on your SSD now.

  • I have one 120GB SSD and one 1TB SSHD, how do do I make one of them my boot drive and the other my data drive?

    I'm currently upgrading my mid-2010 Macbook Pro 13", I've purchased some new RAM and also a 120GB SSD and a 1TB SSHD (Hybrid SSD and HD) with the intention of using an OWC data doubler to get rid of my dvd drive and place the SSD drive there instead. So after I've placed everything into the Mac, how do I make the SSD my boot drive with the OS on it and everything, and the SSHD where all my data (music, photos etc) are stored?

    Youll need to CLONE your internal HD to your target (temporarily) external drive.
    1. grab carbon copy cloner or (my fave) superDuper CLONE app.
    2. attach target clone drive via USB in an enclosure or HD dock. Firstly format the target (external new) HD in disk utility in “Mac OS extended journaled”
    3. clone internal HD to target HD (external)   [takes about 40 mins depending on size]
    4. Boot ONCE from external (go to sys. preference to boot from external) to TEST the new Clone
    5. open bottom (see videos on ifixit or youtube on same) and remove old, install new.
    http://www.ifixit.com/Guide/Replacing+MacBook+Pro+13-Inch+Unibody+Mid+2012+Hard+ Drive/10378/1
    Done
    (FIRST TIME after installing,  boot will be SLOW,...normal and ignore that).
    Clone APPS
    Superduper does not clone the recovery partition, but that is NOT necessary if you keep the original HD as a “backup clone”. Most don’t bother with the recovery partition in a clone, however that is your prerogative.

  • When i boot i get a flashing folder with a question mark. disk utility doesnt work or read my harddrives to boot with. i installed a new SSD and its not reading that either. i have a macbook pro 2011, any help?

    So I came to this problem a while ago. M ycomputer basically froze so I was forced to shut down by holding the button down. When I started it up I got the flashing folder with a question mark. I started it up holding down the command and r keys which brought me to disk utility. Although my computer doesn't read that I have a hard drive to start it up. When I click on the disk utility app, I cannot verify or repair anything either. The buttons won't allow me to click on them. It also shows "Mac OSX Base System" which shows I have files and what not saved. I had been told that I need a new hard drive so I bought and manually installed a OWC SSD 240GB drive and when i booted the computer up it booted up yo the operating system fine with all my files and what not on there. After about twenty minutes, it froze again. I forced a shut down, restarted and the same thing happened. I am not able to choose my SSD to boot up, although thats probably because it doesn't have an operating system installed on it??
    i have a Macbook Pro 13" 2011
    any help would be great, I'm overall confused.

    ryansaint11,
    this isn’t Apple support; this is a user-to-user forum. We’re just fellow users of Apple products here.
    If you want to boot from your SSD, then you should put the SSD where your HDD currently is, and put the HDD into the optical bay. (That setup will also get you the best performance.) At the moment, you’re still booting from your HDD. Note that you will need to format your SSD in Disk Utility [with the “Mac OS X Extended (Journaled)” format] so that you can install OS X onto it.
    Since you have an Early 2011 model, it might or might not have originally come with grey installation DVDs. You will be able to find out whether it did or not by trying to use OS X Internet Recovery to install OS X onto your SSD. If it does not work, or if the installed OS turns out to be Snow Leopard, then it will have originally come with the DVDs, and you should purchase a replacement pair of DVDs from Apple or iFixit; those discs will have your MacBook Pro’s Apple Hardware Test and its iLife apps. If the installed OS turns out to be Lion, then it will not originally have come with the grey installation DVDs, and your Apple Hardware Test will be installed along with Lion, and your iLife apps will be downloadable from the Mac App Store.

  • I'd like to carry my system, applications and files on a portable Thunderbolt ssd drive and boot from it.  I have a Mac Pro in the office, iMac at home

    I'd like to carry my system, applications and files on a portable Thunderbolt ssd drive and boot from it.  I have a Mac Pro in the office, iMac at home, a MacBook Air for when I'm on the road, all with TB.  Can a single external TB drive boot all three hardware configurations successfully?  I've been told that differences in hardware configurations between the systems make this impossible.  Is this correct?

    Piece or peace of cake really though.
    A quick install on new hard drive or SSD or 10K and less than an hour to move everything over properly.
    YOU looked for a quick fix and found none and all the brick walls.
    It is not  days of work to do a clean install and migrate.
    There are few if any apps that need to be freshly installed either though there are updates needed for them to be compliant, any driver or plugin also and that is done ahead of time with research.
    And your backup or clone of your system is taken care of - you leave the old system boot drive 'as is' untouched.
    Also, better strategy to move most all your home folder (except for its own ~/Library) to ANOTHER disk drive and not on t he system drive at all.
    As for applications on its own drive or 3rd party, beeen there done that, even SSD or 15K SCSI - no benefit in performance or organization.

  • Portege R30 won't boot from SSD after upgrade to SSD and HDD under CSM mode

    Hi 
    I upgraded my Portege R30-ASMBN22 to SSD (Crucial M550) and replace the optical drive by the original HDD with caddy.
    In order to install Windows 7, I change the BIOS to CSM mode. But now the system won't boot automatically from the SSD. It only boot from HDD which is in the ODD spot.
    I could press F12 while turning on my laptop, and bring up the boot manual. Here I can see my SSD and I can boot from it correctly. However, if I don't press F12 when it starts. It will always try to boot from HDD.
    In the boot order in the BIOS, I only see HDD/SSD, USB Memory, ODD .... It doesn't give me the option to choose between SSD and HDD. Is there any other way to change the boot order among HDD and SSD?
    Thanks,
    Louis

    Hi,
    I did the same operation to my Portege R30-A-17C, and have the same problem, is there any way to boot without pushing F12 every time.
    Thanks,
