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 Digital and I now have a 3-way mirror, which is effectively a 2-way mirror with its hot-spare already synced in. The idea behind notching up the capacity is threefold: - No "sorry, this disk happens to have 1 block too few" problems on attach. - When the 1.5 TB disks _really_ break, I'll just order another 2 TB one and use the opportunity to upgrade pool capacity. Since at least one of the 1.5TB drives will still be attached, there won't be any "slightly smaller drive" problems either when attaching the second 2TB drive. - After building in 2 bigger drives, it becomes easy to figure out which of the drives to phase out. Just go for the smaller drives. This solves the headache of trying to figure out the right drive to build out when you replace drives that aren't hot spares and don't have blinking lights. Frankly, I don't care whether the Samsung or the WD drives are better or worse, they're both consumer drives and they're both dirt cheap. Just assume that they'll break soon (since you're probably using them more intensely than their designed purpose) and make sure their replacements are already there. It also helps mixing vendors, so one glitch that affect multiple disks in the same batch won't affect your setup too much. (And yes, I broke that rule with my initial 2 Samsung drives but I'm now glad I have both vendors :)). Hope this helps, Constantin Simon Breden wrote:
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?
