5 platters. no wonder it's cheaper.
More platters means more heads which should mean more throughput, so I don't mind that. By the same token, it's hard for me to get past the days when people used to refer to these as "death stars".
All HDD's fail at random times, you get 2 mirror them (Raid 1) and STFU. $160 is dirt cheap insurance policy for 2TB of data loss, time loss, headaches, etc.
this isn't a deal!
So show us something better, #4...
yeah... we're waiting #4...
5 platters huh. Wonder if one of them is redundant? I thought most companies had moved on to 500gb platters
Raid won't protect your data in all cases. All the components in my home machine were fried recently (probably caused by the Antec PSU). IMO the only way to protect data is to back it up onto DVDRs.
oh please... a PSU killing hard drives, "probably"? what is that one in a million, sure it wasn't a power spike, brown out, etc. You have power conditioning? UPS? Backing up 2TB on 450DVD is the most asinine thing I've ever heard of on BB today...
#7 is right, the state of the art is 500GB/platter. More platters means more power. If your HD dock/power supply do not have enough margin, this might not be such a good idea.
I would rather get a 1.5TG 3 platters drive. Waiting for it to drop in prices. There have been deals for 1.5TB to sell at below $100, so $160 for a 2TB drive is not such a good deal.
If you are using it as external storage drives, then the rpm number may not matter as much.
I use a surge protector but no power conditioning or UPS. As for backups, IMO you need something external to be safe for the reason I mentioned above. It could even be an external drive which is not always connected to the machine.
I backup my 1.5TB drive to floppy every night.
3 1/2 or 5 1/4 or maybe even 8 inch?
8" like in War Games. By the way, here is everything you ever wanted to know about this drive:

Yeah...thats hours of reading. That'll shut this thread up for a while.
#12 you need a warehouse too.
What do the number of platters offer as a benefit or drawback? Thanks.
#17, nothing significant. People just like to sound smart by bringing it up.
#18, have you checked the power dissipation figures of drives with different platters before you posted your "smart" comment?
Here is some data from Hitachi site:
Idle power for 7K1000B (7200rpm, 3 platters): 5.2W
Idle power for 7K2000 (7200rpm, 5 platters): 7.5W
Read/write powers are higher, but same difference between 2 drives.
If your power supply/adaptor is marginal, or if the drive is enclosed in enclosure without good cooling, then it may matter.
#2, actually more heads/platters do not mean more throughput. Keep in mind that all actuator arms that carry the heads are synchronous such that all heads are positioned at the same track on each surface. So unless you store data in such a way that data from same file are stored in similar tracks on different surface AND the drive software/hardware can support multiple heads read operations you don't get simultaneous reading of data.
On the other hand, fewer platters for same data amount storage means higher data density per track and thus higher throughput at same rpm.
