    If you really want to destroy your data, thermite is the key. Just mix aluminium powder and iron(III)oxide in a 1:3 w/w ratio (1 kg should do the trick), place it in a flower pot on top of your HDD, put on your sunglasses and light it. But maybe you're not so serious about destroying your data?

    Seagate finally offering a down to earth priced internal 4TB HDD.

    Louder, yes for sure. Not that much hotter though. My 5 Seagates have an average temperature of 31°C while the WD Greens are at 28°C. The WD disks are sitting in a 4-in-3 bay though, and the Seagates are in 3-in-2 bays so the cooling is better for the WDs. Apart from the one WD which is sitting...

    Seagate finally offering a down to earth priced internal 4TB HDD.

    After using these drives for a while I have really started to take notice of the noise they are making. They are much louder than my WD Greens when seeking. Is there any way to silence them? It seems that AAM is not an option, but are there other options?

    Shadow migration speed

    I tried changing the shadow_throttle and it seems to have no effect. Upon further investigation it seems that the shadow_throttle is only used when there are errors in the file system. I found comments like this inside of the source code: I did manage to speed up the transfer by increasing...

    Shadow migration speed

    I got a new ZFS pool that I wanted to transfer data to from my old pool. After some attempts at zfs send/recv and not getting it to behave properly I discovered this service in Solaris called Shadow Migration...

    Seagate finally offering a down to earth priced internal 4TB HDD.

    Roughly 6% (10 hours) into the badblocks test I've got a Runtime_Bad_Block count of 1 on two of the disks. What does this mean? Is this a reason to be concerned or "normal"? I can't find any explanation for what runtime bad blocks means. Badblocks hasn't reported anything though.

    Seagate finally offering a down to earth priced internal 4TB HDD.

    I got my drives today and they are indeed 5900 RPM. At least this is the value reported by the disk. I also did a frequency analysis using a contact microphone which showed a peak at 99 Hz (5940 min‾¹). Now the remaining question is why Seagate told my distributor it was a 7200 RPM...

    Seagate finally offering a down to earth priced internal 4TB HDD.

    The disks have been shipped! Hopefully I will know exactly what they are tomorrow. I already know the serial numbers and I can confirm that the warranty is 2 years (Expiration 24-May-2015) by checking it on Seagate's website. It gives the same expiration date for both the US and Sweden. Any...

    Seagate finally offering a down to earth priced internal 4TB HDD.

    This is getting interesting now. I asked my supplier of the disk about the specs for the ST4000DM000 and they confirmed that it is 7200 RPM with 2 years warranty. They said that this information came directly from Seagate. It will be very interesting to examine the disks when I get them...

    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    That encryption is not done inside of ZFS, but rather on a disk level, right? So you have to enter the password for each disk? That's a lot of work if you have many disks and secure passwords. Solaris supposedly does use AES-NI, but the implementation seems to be rather flawed as it doesn't...

    OpenZFS NAS (BSD, Illumos, Linux, OSX, Solaris, Windows + Storage Spaces) with napp-it web-gui

    I'd love to switch from Solaris, but it has something I want that the alternatives don't; encryption.

    Now I've upgraded to 11.1, but unfortunately I still have the same problem.

    12 new consumer drives from Toshiba

    I think the Toshiba got the specs wrong on those disks. Power consumption is highest when idle and lowest during read/write operation? I think not. I would contact them so that they could fix that if only I knew how.

    Seagate finally offering a down to earth priced internal 4TB HDD.

    I'm pretty sure the store has to give whatever warranty they write on their site here. It may be different in other countries, but in Sweden we have pretty strong consumer protection. Yeah, but we're a little behind here in Sweden. Another store had today as the expected delivery date, but is...
