An In-Depth Look At Seagate's 1.5TB Barracuda
theraindog writes "More than a year and a half after the first terabyte hard drives became widely available, Seagate has reached the next storage capacity milestone. With 1.5 terabytes, the latest Barracuda 7200.11 serves up 50% more capacity than its peers, and at a surprisingly affordable $0.12 per gigabyte. But Seagate's decision to drop new platters into an old Barracuda shell may not have been a wise one. The Tech Report's in-depth review of the world's first 1.5TB hard drive shows that while the latest 'cuda is screaming fast in synthetic throughput drag races, poor real world write speeds ultimately tarnish its appeal."
How important is throughput? I'd be interested in knowing what percentage of these drives are going in external enclosures. For the time being, 1.5tb is much larger than you'd need to be running any applications off of and I'd guess the majority of these drives are going to be storing movies, mp3s and photos, where the speed hardly matters at all.

I've always had good luck with these drives. It's the only brand I'll buy and recommend to another person. The fact they will warranty their drives for 5 years where most others will only do 1 - 3 years says something about them. If they're betting their drives will last 5 years, who am i to argue?
Hey, everybody's thinking it, I'm just saying it. ;)
Obligatory Soundbite Catchphrase
Has anyone else noticed that a large number of the Seagate 1T drives fail on you in 30 days. The same is true for samsung and WD. Even with the Hitachis I get 1/5 failed out of the box. I still buy all Hitachis though, because the ones that do work keep working. Why are we moving to 1.5T when the 1T are too buggy to be useful. (BTW, my epxerience is based on buying 100+ drives).
I've managed to fill 2/3rds of my 1TB storage drive already.
Your wrist must be tired!
I have a few of these drives... they are very fast for sequential read (>120MB/s sustained)
However, if write-cache is enabled (default) Linux will freeze intermittently reporting a SATA timeout executing a cache-flush command.
Tested with the 2.6.24 and 2.6.26 kernels. Other people have reported the same problem with the 2.6.27 kernel.
Tested with multiple drives and multiple SATA controllers (different chipsets). No SMART errors logged.

The workaround is to disable write-cache on the drive.
I wonder why nobody is making 5.25" hard drives anymore... With current technology they could have at least 10TB capacity...
Two words:
Angular Momentum
At the outside of the disk there would be an incredible amount of stress on the rotating media.
The head seek times would go up as well....
Though, while 7200+ RPM would certainly be out, and likely 5400 RPM as well (remember the old drives ran <= 3600RPM, I would consider a 4200 RPM 10 TB drive for near-line storage...
even 5.25/FH that would be a decent volumetric density (equivelent to 5x 3.5" drives).
