Any ideas if Hitachi will announce anything new at CES? I'm in the same situation a lot of people are with these seeming to be the last option for 2tb drives in RAID arrays, unless anyone's tried the samsung f3eg 2tb drives.
If you haven't yet downloaded the "Hitachi Feature Tool", you may want to. It's a DOS based utility for changing various features of Hitachi drives, things like APM settings, SATA speed (SATA150 / SATA300), etc. It's available on the Hitachi downloads and utilities page here (the page also has tools like the DFT - Drive Fitness Test, etc):
I am seriously considering moving to this drive after 6 months of fighting with Seagate drives. I'm have my array on an Areca 1231 and am just about to RMA my 4th drive in those 6 months (from an array with only 8 drives no less - 50% hard failures in 6 months). My bad for failing to visit these forums and failing to learn from others mistakes...
7200.11 1.5Gb. The infamous ones. If I had just spent a bit more time reading first I could have avoided the headache.
Just wondering, are you having the firmware bug? I had one that was DOA, one that had the bad firmware and died week 1, but all 15 of them since have been flawless. These WD Green 1.5TB's however... a third (this week) of eight threw a SMART error last night. Alas, I've purchased 6x 2TB Hitachi's and 2x 1TB drives in the last week. They just work apparently.
I've been using a "dog slow" Adaptec 31605 with them... and for whatever reason they just work. The Hitachi's work. Everything just works, which is really nice. Plus, the old WHS only had two Realtek GigE's to saturate so even "dog slow" is easily fast enough.
I was thinking of putting the Hitachi's in a 'sidecar' but I'm super worried about something like an ant shorting out he external enclosure and losing the array. Probably highly irrational although my other idea is to just flip the Norco RPC-470 that has trayless backplanes and mount it atop the RPC-4020 making an oddly cobbled together 8Uish monster. I think it's a bad idea but I sketched it on a post-it in a meeting today.
The odd thing is that at the same time they introduced the 5 platter 2TB drives they introduced 2-platter 7200rpm 1TB drives, so they have the capability to make 4 platter 2TB drives.
What makes these Hitachis work so smoothly anyway? Just better engineering or firmware? You'd think w/more platters on 'em they'd be more fragile, noisier, and/or warmer... I know it was forever ago but I still have bad memories of my dead 5-platter IBM 75GXP (I think that was the last 5-platter drive I've ever owned too). I admit I haven't kept up enough w/the HDD market, just enough to know what to avoid (like Seagate's 7200.11, etc.).
This is incorrect- if they could've put out a 4-platter 7200RPM 2Tb instead of 5-platter, they would have. There was an engineering issue specific to four platters @ 500Gb per platter when spun higher than a certain RPM. At 7200RPM supposedly the poor SNR produced error rates that were out of control. Meantime read/write head tech may have advanced and overcome that, but I don't think it was a marketing conspiracy if thats the concern.
Experience has shown the issue of 5 versus 4 platters ends up being more psychological than anything - 20% more platter and heads might lead you to believe its 20% more likely to fail but in real world use the failures just aren't happening.
