Your opinion on perpendicular HDD

biochem_bill · 12-03-2008, 09:59 PM

I recently replaced the HDD on my laptop with a 120G WD. I was very close to buying a Hitachi 160G with perpendicular recording technology but got cold feet and went with WD. Just curious if anyone has any experience with perpendicular recording and if so what your thoughts on it are. I'm thinking about replacing another HDD and might go with this.

The perpendicular drives are very nice, in the real world you wouldn't notice much, if any, performance difference between that and a raptor. Well, aside from the noise, of course. I stuck a nice expensive raptor into a spare machine, got so tired of listening to drive access. Went back to a quieter, bigger, and much less expensive seagate and vastly prefer that.
Look at the throughput for the 7200.11 seagate.

yeah, those seagates 7200.11's are no joke! i got 3 in RAID 5 :D A flagship in its class!

Make sure you pull out the jumpers though as they limit to only 1.5 GB/s

Update:
Oh, hehe, just noticed your avatar, grimx133, i got the same case too :D

As with any new technology I too was a tad afraid to make the leap. You never know... maybe all of a sudden on the second year after they're introduced, all the drives will start to fail suddenly without warning (think the IBM Deskstar 75GXP)*. But apparently perpendicular technology drives seem to be doing well so far. They at least seem to be lasting their warranty period so far. Aren't most drives today perpendicular anyway? (just saying you don't have the choice anymore)

Yeah, it seems all the new ones are... the thing i noticed the most is that they're smaller/lighter. I work in an environment where we use 100's of these and some fail, but the rate is as low as expected and just part of life. I feel very comfortable with PT and seagates :)

I haven't noticed that perpendicular drives are not intrinsically any more prone to failures. The head/slider assembly is much smaller and delicate. Tolerances are tighter. They do tend to send shivers down a data recovery techs back though when they come in and need a head swap LOL.
