    A word of warning, there seem to be problems with certain firmwares of the Samsung F4EG. Be cautious and read up about it before using smartctl on these drives!

    Yeah, that was my conclusion too. I directed him here from another thread, I believe he is working on it and will reply his results here! Has has never used SVN building before (which I had not also, before smartctl).

    PCIe eSATA Card Advice

    The VERY VERY cheap and dirty solution : http://www.addonics.com/products/host_controller/ad2sa6gpx1.asp . Not sure what you are wanting to do with it and if you would wish to use something like this in a business situation or not, but still. But sure to read the limitations. This card has shared bandwith (not non-blocking) and also should be used on a PCI-E 2.0 port if you wish maximum performance.

    Sorry for the very late reply. Not been around much lately, busy busy! Yes, WINDOWS software raid should not affect the ability of smartmontools. This is because you can still talk to the physical disk and thus you should be able to send commands to it directly. You might need to use their SCSI ID and not the drive letter, but that is a simple issue to solve. So if we are talking about say an intel ICH controller. No problem, software RAID or not. You need physical device access. The supported RAID controllers (like my adaptec) provide this.

    PCIe SSD Test Chamber

    ... I'm a bit at a loss here. What is a "test chamber" and what tests does it preform? See how the SSD holds up during extreme temperatures, etc.?? Heat should be faily easily to simulate yourself for instance. Please elaborate.

    I am actually the one using the Adaptec controller. Since I use VMware ESXi 4.0u1 on my server, I also have no way of running smartctl from the OS I am using. For this reason I use a bootable USB stick with Fedora installed. Fedora and their adaptec drivers are configured in such a way that next to your data arrays, they also provide a "SG" of your disks connected to the adaptec controller, a feature called "expose physical drives". With that, you can access the SMART data as if the disks are connected to a simple controller and also preform actions on them such as the Smartctl SCTERC commands. And off course read other stuff out of the disks. I also use this to run my Adaptec ASM software, since there is no version for VMware ESXi. Works great, if you do not have to powerdown your server too much. It takes about 5 mins in total to boot from the stick, set the desired commands and reboot into VMware ESXi. I know of no other way to get around this using windows, or even any other linux distribution for that matter. Normally I'm more prone to use Debian or Ubuntu, but I could not get the switch to work for me. Not a linux expert though. Hope this helps you, let us know!

    why so many large drive failures

    Ah, well, I have had dozens and dozens of disks go through my pc's/servers over the years. I have been running a storage server for years and thus upgrade once in a while and try to double the capacity when possible. This started with 20GB disks and has now moved to 2TB disks. So I have had 20GB's, 60GB, 120GB, 250GB, 500GB, 1TB, 1.5TB and now 2TB disks in my server (server itself has changed hardware too but in the most recents years I have been using adaptec controllers, so you could call that a constant. ). I've run from 4 disk RAID5's to 8 disk RAID5's. And have had some failed disks over the years.... treating them quite badly actually. I run the server 24Hr a day, for weeks on end, then shut it down, put it in the car, drive it to a lanparty, turn it on again for 48Hrs where the disks get trashed, turn it off again and put it back into it's spot where the disks spin again for a few weeks. Well, I can tell you, desktop disks (or any?) are not designed for that kind of usage. Oh, and my cars mostly have subwoofers in the back too, where mostly the server would stand also. Never had any effect on it that I could tell. But, since I have 3 years warranty mostly, I got by pretty well. Especially Maxtor was my friend with their advanced replacement program! :D Most disks would take 1 tot 1,5 or 2 years of this kind of punishment, in all honesty, the average lifetime you would expect from the disks in power on hours and reads, but normally over much larger time say 5 to 10 years. Anyway, in all my time with all my type of disks and array's and everything, I have never!!! lost as much data as I did this time. I have never had so many disks just fail, for no apparent reason. And now a days my disks are in nice holders in chieftec hotswap bays, etc. etc. So no, I am used to having a much better experience. Just like you are from what I get from your story. Sadly disappointed and I am hoping the replacement disks won't fail as horribly too!

    why so many large drive failures

    Just to add to this discussion a bit. 3 of the 7 Samsung EcoGreen F3EG 2TB disks have developed bad sectors this week and caused me a large amount of data loss. Quite a bad score if you ask me.

    Hmm, that's odd. That should work exactly as described. What did you set your controller to? It should be in AHCI mode for best result. Also, using your motherboard controllers RAID function will probably not give you the ability to use smartctl. But, using motherboard RAID is hardly or any better then using software RAID. Win2k3 does this fine, but consider Win2k8 R2... several great improvements! Also this will keep your array transportable between hardware, and also give you the ability to use smartctl! Win win situation I would think. Performance should be at least the same, you only forgo the ability to boot a RAID5. But create say a 50GB RAID1 (software raid, bootable) and then use the rest in RAID5. I've run like that before, works perfect! Let us know!
  10. Not sure what to awnser here, I can tell you though that 270MB/sec or even 200MB/sec is not attainable with a single drive. So I am not sure which specs you are looking at, but they do not sound realistic. About the reliability I am also not sure what to say. WD's are good, but Samsung's are not supposed to be bad. Currently having some trouble with my raid set, but I have other Samsungs which show no problems whatsoever.
  11. Nope. That was the old version. The new version has certified the X25-M's too and also you do not need to buy them from Adaptec anymore. This was announced at the Cebit and has since been built into the firmware from 2 or 3 weeks back. Also, more firmware updates should follow which will allow you to do write caching on an SSD as well. Personally I use my server for VMware ESXi purposes and I believe it could mean a great improvement for me! I have not tried the new firmware yet or have the SSD. But I believe it will be required to enter some kind of unlock code to enable the feature.

    Loving my new home server speeds

    Anymore specs or anything for us to go on here? Software RAID, Hardware RAID, SSD? Anything? Always good to share, but give us some specs and how you configured things, so others can learn from it also. Your speeds are a bit on the slow side I would say. A single disk should easily do 100MB/sec read and write at the beginning of the disk (Generation of 1TB disks or larger). So there might be something wrong, or there might not be. No clue....
  13. I too think this is a very interesting technology which will actually shape the storage to come in the next few years. I have an adaptec 5805 myself and am willing to pay for the SSD (consumer intel version), but don't want to buy the adaptec license for it. I runs a 7x5400 RPM 2TB array using VMware ESXi 4.0. Perfect enviroment I would say to see great SSD speed gains. Sadly, no key, no glory.
  14. What would be good is if you could do a media verification run on the disk (some controllers can do this in bios) or otherwise use the tools specific to the brand disk to test it if it's still good or not. For all of this you'll need to hook it up to a PC though.
  15. Ah, great to hear it's been fixed. I've only ever used the adaptec cables with the adaptec controllers. Will think twice about buying different ones now! Weird it did not work though.
