Hello all. I wanted to revive this thread to relay this bit of news about hard drive warranties. Its not a new story (Dec 2011), and lots of you are already painfully aware of it, but others just starting to build out a system may not have seen it and this might alter some purchase decisions: E

Hi All, We run a couple to 18 TB File Servers using 8 x 3TB drives in a RAID6 array (no LVM). We use the 5400 RPM Hitachi Deskstar drives and get great performance, life, and power usage. We chose these drives based off a recommendation and the data collected here: http://blog.backblaze.com/2011/0

I have 2 drive of 3 TB [HITACHI DESKSTAR] each one in Mirror Raid; using a [HighPoint RocketRAID 620] controller; this is SATA v3.0 at 6GB/s. Now when you use more than 2.5 TB Drives this work with a new way to manage partition called GPT [Guided Partition Table] unsupported on major versions of L

You normally find server drives when you look into SAS or the high rpm SATA drives (either 7.2k 2.5" or 10k+ 3.5"). Look up dell, hp, ibm drives and then die a little when you see the price. To be honest a lot of the enterprise SATA drives are the same as the consumer grade you're paying

I have seen Seagate and perhaps WD market them as "Enterprise" drives, with a comparatively higher price. I have also seen "AV" drives, i think those were WD, designed for Security systems and similar devices. I assume they are the same, higher grade of drive. Nathaniel C. Steele Assistant Chie

Hello, Here, at our student radio station, we use LVM. Each physical volume is a double RAID 1 array of disks. So LVM makes it a JBOD. We can expand it anytime on the fly if we hot add disks in our bay, which hosts several SATA controllers, some of them are currently unused, but ready to accept ne

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 ZFS is lovely, but a bit of a pain to configure, and effectively unsupported on Linux - so you need FreeBSD for your fileserver. Which may be a degree of complexity too far. LVM is not as fantastic, but also very simple. For a simpler solution I'd g
