Sounds good. I was taking a look at the 1TB Caviar Black drives which are WD1001FALS I think. They seem to have superb user ratings and good reliability comments from many people. I consider these "full fat" drives as opposed to the LITE (green) drives, as they spin at 7200 rpm instead of 5400

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

So 2TB would become 500GB, but better then a normal 500GB SATA. ( Or in your case, swing it down to 750Gb ) Regards, Armand - Original Message - From: "Simon Breden" To: Sent: Saturday, January 23, 2010 7:53 PM Subject: Re: [zfs-discuss] Best 1.5TB drives for consumer

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

Hi Bob, Why do you consider that model a good drive? Why do you like to use mirrors instead of something like RAID-Z2 / RAID-Z3? And how many drives do you (recommend to) use within each mirror vdev? Cheers, Simon http://breden.org.uk/2008/03/02/a-home-fileserver-using-zfs/ -- This message po

Reading through your post brought back many memories of how I used to manage my data. I also found SuperDuper and Carbon Copy Cloner great for making a duplicate of my Mac's boot drive, which also contained my data. After juggling around with cloning boot/data drives and using non-redundant Ti

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

In general I agree completely with what you are saying. Making reliable large capacity drives does appear to have become very difficult for the drive manufacturers, judging by the many sad comments from drive buyers listed on popular, highly-trafficked sales outlets' websites, like newegg. And

Interesting question. The answer I came to, perhaps through lack of information and experience, is that there isn't a best 1.5tb drive. I decided that 1.5tb is too big, and that it's better to use more and smaller devices so I could get to raidz3. The reasoning came after reading the case for

Hi Constantin, It's good to hear your setup with the Samsung drives is working well. Which model/revision are they? My personal preference is to use drives of the same model & revision. However, in order to help ensure that the drives will perform reliably, I prefer to do a fair amount of rese

Hi, I'm using 2 x 1.5 TB drives from Samsung (EcoGreen, I believe) in my current home server. One reported 14 Read errors a few weeks ago, roughly 6 months after install, which went away during the next scrub/resilver. This remembered me to order a 3rd drive, a 2.0 TB WD20EADS from Western Digit

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

I see also that Samsung have very recently released the HD203WI 2TB 4-platter model. It seems to have good customer ratings so far at newegg.com, but currently there are only 13 reviews so it's a bit early to tell if it's reliable. Has anyone tried this model with ZFS? Cheers, Simon http://br

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

Thanks. Newegg shows quite a good customer rating for that drive: 70% rated it with 5 stars, and 11% with four stars, with 240 ratings. Seems like some people have complained about them sleeping - presumable to save power, although others report they don't, so I'll need to look into that more.

HD154UI/1AG01118 They have been great drives for a home server. Enterprise users probably need faster drives for most uses, but they work great for me. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

Good to hear about the Samsungs working for you. Which model/revision are you using? I think your cautious method of not trusting drives, and making an initial trial mirror is a good one, and I might well do what you've done for the next batch I buy. I also use RAID-Z2 vdevs and it feels a lot

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

I've been having good luck with Samsung "green" 1.5TB drives. I have had 1 DOA, but I currently have 10 of them, so that's not so bad. In that size purchase, I've had one bad from just about any manufacturer. I've avoided WD for RAID because of the error handling stuff kicking drives out of arra

Re: [zfs-discuss] Best 1.5TB drives for consumer RAID?

Which drive model/revision number are you using? I presume you are using the 4-platter version: WD15EADS-00R6B0, but perhaps I am wrong. Also did you run WDTLER.EXE on the drives first, to hasten error reporting times? -- This message posted from opensolaris.org

Which consumer-priced 1.5TB drives do people currently recommend? I had zero read/write/checksum errors so far in 2 years with my trusty old Western Digital WD7500AAKS drives, but now I want to upgrade to a new set of drives that are big, reliable and cheap. As of Jan 2010 it seems the price sw
