  • Make the recycle bin of the SSD on a RAID0 drive?

    - by Rolnik
    I don't know about you folks, but I hate the idea of junk sitting on my tiny 30GB SSD. Any way to designate another drive to be the host of the Recycle Bin for items formerly on the SSD? Basically, I need to know how to make a lower-priority drive receive the recycled materials from the 'main' drive, which happens to be short on space. The best thing I can think of is a batch file that a) syncs 'recycle' to another drive; and b) empties the recycle bin. ... but that's too much work for me.

  • Lenovo N100 and Samsung SSD 830, shouldn't this go faster than 100MB/s?

    - by Jook
    I recently upgrated my Lenovo N100 0768 with a Samsung SSD 830 - specified to support 520 MB/s read and 320MB/s write. However, having only SATA1 with max. of 150MB/s speed, it has to run in a slower mode - of course. But, shouldn't it be more on the edge of this limit than ranging between 90-115MB/s and averaging around 103MB/s? Or is this really as much as I can expect? Tested with HD-Tach. Has anyone comparable results on a SATA1 controller with a SSD drive faster than SATA1? Preferably similar to the Samsung 830?

  • Why do SSD drives get so much more expensive as they get larger?

    - by futuraprime
    Normal HDD costs go up very little as drives get larger. For example, an average 1TB drive costs a little under $90, 2TB costs a little over $100, and a 3TB drive costs close to $150. For HDDs, the cost per GB goes down as the number of GB goes up. SSD costs don't work like this: a 128GB SSD goes for $120ish, 256GB goes for $250ish, and 512GB drives get up to $600. The cost per GB goes up as the number of GB rises. What is it about SSDs that makes them so much costlier as they get larger?

  • Will adding a SSD cache device to my ZFS storage improve performance?

    - by Sysadminicus
    The server has 4GB of RAM and my zpool is made up of 15.5k SAS drives arranged like this: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 raidz1-0 ONLINE 0 0 0 c0t2d0 ONLINE 0 0 0 c0t3d0 ONLINE 0 0 0 c0t4d0 ONLINE 0 0 0 c0t5d0 ONLINE 0 0 0 c0t6d0 ONLINE 0 0 0 c0t7d0 ONLINE 0 0 0 c0t8d0 ONLINE 0 0 0 raidz1-1 ONLINE 0 0 0 c0t10d0 ONLINE 0 0 0 c0t11d0 ONLINE 0 0 0 c0t12d0 ONLINE 0 0 0 c0t13d0 ONLINE 0 0 0 c0t14d0 ONLINE 0 0 0 spares c0t9d0 AVAIL c0t1d0 AVAIL The primary use is as an NFS store for a couple VMWare ESXi servers. I can't do any "true" benchmarks because this is a production system (no budget for test systems), but using dd and bonnie++ I can't get more than ~40-50MB/s writes and ~70-90MB/s reads. It seems I should be able to do much better, but I'm not sure where to optimize. Based on what I've read, I think dropping in a OCZ Vertex 2 Pro SSD as my L2ARC is going to be the best bang-for-the-buck to improve througput. Is there something else I should be looking into to help performance? If not... How do I know how big a cache device I need? Am I safe with only a single SSD as my cache device?

  • What diagnostics are safe to run on an SSD drive?

    - by Peter Mounce
    I have a MacBook Pro (late 2010) with a Crucial RealSSD 256Gb in it; 60Gb is given to the Windows 7 x64 BootCamp partition. I have a USB-attached 500Gb drive for (most) data. In the last day or so, I've had a BSOD and several OS freezes (both Mac OSX 10.6.6 and Win7). The system in both cases will boot fine (at the moment!) and then run things fine, then some time later a program will stop responding, followed shortly thereafter by the system as a whole, forcing a reboot. This smacks to me of a storage problem. Given that I have an SSD and not a regular magnetic HDD, what are my next steps, in both OS'? I haven't seen anything pertinent in Windows' event-log. I'm not sure of the equivalent place to look in OSX; it's never given me issue to find out. What are my options for attempting to save my data from the SSD to another drive, given that after some small amount of time (eg half an hour), the OS stops responding? What are the recommended next steps?

  • How is the extra mSATA SSD disk used/configured in a Dell XPS laptop?

    - by Mark
    Some machines in the new XPS laptop range from Dell come with a regular, large (500GB+) HDD and an additional 32GB m-SATA SSD. The only detail I can find about this extra drive on the Dell site is this: Store your important files, multimedia and photos with XPS 15’s large hard drive options. To get instant access to your media, choose an optional mSATA solid-state drive (SSD) that can boot up to twice as fast as a regular hard drive and resumes in less than 1 second. I'd like to know more about how this extra drive is set up and used, specifically: Is anything installed on it (e.g. OS files or a boot loader) or is it just used as swap space? Is the m-SATA drive visible as a lettered drive in Windows? (I'd guess not if it's used for swap file only.) Is this unusual configuration likely to cause any problems later down the line - e.g. when upgrading to Windows 8? As usual, Dell's sales team haven't been able to help. If anyone's actually got a Dell machine with this or a similar hard drive set-up and can give a definitive answer rather than speculation I'll accept the answer.

  • System randomly freezes yet mouse still moves, SSD out of reallocatable sectors, should I replace it?

    - by user784446
    This problem has lasted for the past 48 hours. The first time it happened, a program I was running stopped responding, so I tried to end it from task manager. The processes at first were listed fine until hovered upon. Eventually, despite the mouse still being able to move, after a few persisting clicks the mouse finally stopped moving. The screen went blank shortly thereafter. The second time it occurred, items on the screen stopped responding - hovering over the taskbar or such wouldn't elicit a response. Sound would still play however. Eventually, the mouse became unresponsive and the system restarted itself. I suspect that it may be a problem of my SSD drive. After looking through some Google search results, I downloaded HDTunePro to determine if there's a problem with the drive. Results returned a problem of reallocated sector count. An error scan also revealed 48 bad sectors. Also, an attempt to backup the contents of the most important areas of the drive returned a few explorer "Error: cannot read source from disk" errors. Should I ditch the drive and use another drive or is there anything that can be done to repair the drive? SSD: OCZ Petrol 64gb CPU: AMD Athlon II X4 640 RAM: Generic 3GB DDR2 Motherboard: Gigabyte MA74GM-S2H OS: Windows 7 Ultimate x64 Thanks!

  • Can I install windows on an SSD and access data from my old windows HDD?

    - by nzifnab
    I purchased new computer components, switching my hardware from AMD and Radeon to Intel and Nvidia. I kept components from my old computer like the powersupply and two HDDs. Everything appeared to install correctly and the system booted into the BIOS just fine (after a brief snafu with the CPU fan). My goal was to use the two harddrives and just be able to turn on the computer and load up my old windows install with all the files, programs, and documents. I expected to have to call Microsoft to re-register the windows install for the new hardware (since I had to do that last time I upgraded w/ the same windows version). When the computer attempts to boot into windows it briefly flashes a bluescreen and then restarts. System recovery gives a message something like "BadDriver Failover" something something. I assume this is because it's trying to use amd drivers for an intel chipset (or something...?) and I've been as-yet unsuccessful in getting it to boot into my old windows partition. SO! I decided eff it, maybe I'll go visit my nearest Micro Center and buy a 200 GB SSD, install windows onto that, and then... be able to access just the contents of both of my other harddrives? I don't intend on running any of the programs but there were some saved files I would like to salvage from the 500 GB harddrive, The 1.5 TB harddrive only had files on it, no OS or applications so I'd also expect to still be able to access it. Is this possible? Can I install the SSD and only format/install windows onto it and still access the contents from my two transferred-over drives?

  • Is post-sudden-power-loss filesystem corruption on an SSD drive's ext3 partition "expected behavior"?

    - by Jeremy Friesner
    My company makes an embedded Debian Linux device that boots from an ext3 partition on an internal SSD drive. Because the device is an embedded "black box", it is usually shut down the rude way, by simply cutting power to the device via an external switch. This is normally okay, as ext3's journalling keeps things in order, so other than the occasional loss of part of a log file, things keep chugging along fine. However, we've recently seen a number of units where after a number of hard-power-cycles the ext3 partition starts to develop structural issues -- in particular, we run e2fsck on the ext3 partition and it finds a number of issues like those shown in the output listing at the bottom of this Question. Running e2fsck until it stops reporting errors (or reformatting the partition) clears the issues. My question is... what are the implications of seeing problems like this on an ext3/SSD system that has been subjected to lots of sudden/unexpected shutdowns? My feeling is that this might be a sign of a software or hardware problem in our system, since my understanding is that (barring a bug or hardware problem) ext3's journalling feature is supposed to prevent these sorts of filesystem-integrity errors. (Note: I understand that user-data is not journalled and so munged/missing/truncated user-files can happen; I'm specifically talking here about filesystem-metadata errors like those shown below) My co-worker, on the other hand, says that this is known/expected behavior because SSD controllers sometimes re-order write commands and that can cause the ext3 journal to get confused. In particular, he believes that even given normally functioning hardware and bug-free software, the ext3 journal only makes filesystem corruption less likely, not impossible, so we should not be surprised to see problems like this from time to time. Which of us is right?

  • Should I keep my swap file on an SSD drive?

    - by Steve Rowe
    I'm considering getting an SSD drive to run as the primary OS partition. As I understand, this should provide a substantial improvement in performance. My question is this: Should I leave the swap file on that drive? The swap partition will be largely random seeks and so should benefit from the speed. On the other hand, it will be constantly written to which will wear out the drive faster.

  • After adding a SSD to my MacBook, the HD never spins down.

    - by Chris Woods
    I added a SSD to my MacBook Pro 17 as the primary drive attached to the SATA controller. I moved the HD to the optical bay using the OptiBay from MCE Technologies which I use for my home directory. The problem I have encountered is the HD seems to never stop spinning. I have modified the sleep settings, hoping one of the various options would solve my problem without success. Any suggestions for me?

  • Partitioning a 128GB SSD and 500GB HDD

    - by Gladen
    So I have a 128GB SSD and 500GB HDD. I want to reïnstall my laptop and put Ubuntu 12.10 on this setup. I already looked around on the internet and came up with this partitioning schema: about 2GB of swap on the SSD (I got 4GB of RAM in my laptop) / using the rest of that space /home on the HDD So I was wondering, are there any better schemes or extra partitions that I should consider putting on a particular drive? Thanks in advance! :)

  • Using ssd intensively. Should we worry?

    - by vvavepacket
    I'm currently using conventional HDDs like the 5200 rpms, browsing a lot, my folder and files are scattered, torrenting always and I'm not fond of optimization like disabling cache, cleaning temp Files , etc. My question is, given the above conditions (no disable of cache, seeding always in torrent, downloading torrent) is it safe to use SSD? I'm pretty worried about cycles but I read an article wherein it says its safe since it will usually wear out for 10 years given that you always write heavily and continuously. Thanks

  • Run fstrim from LiveCD

    - by CharlesW
    A few years ago I installed Ubuntu 10.04 with LVM + LUKS on a system with SSD, TRIM was not enabled. Now I want to install Ubuntu 12.04 on the same SSD. I have found a guide explaining how to enable TRIM on Ubuntu 12.04 with LVM + LUKS, but before installing the new system, I want to clean out all the "marked for deletion" data generated under Ubuntu 10.04, to make the disk fast as new. My plan is to boot a Ubuntu 12.04 LiveCD and create a new ext4 filesystem on the SSD, then mount the filesystem and run fstrim on it. After rebooting the LiveCD I will install the system as normal, and enable TRIM. Can anybody say if this will work?

  • Get access to files on old HD installation and remove system files

    - by Blake
    I have been fooling with ubuntu for only a year or so. Added SSD installed ubuntu(12.04 64bit) connected old drive with ubuntu on it. everything seems to work well, except for access to some files. I would like to do two things: 1) move the swap file from the SSD to the partition on the HD. 2) remove ubuntu system files and gain full access to my other files. I can still remove the SSD and run ubuntu from the HD, so if I am approaching this incorrectly please advise. Thanks in advance Blake
