Limit 1 of each per customer, shipping is about $7.48 for 1, $8.08 for 2x.
Retail boxes, with full 5 year warranty. Site shows 7200.10 model numbers. Play Fry's "how old is your stock" game and if you're lucky you might end up with 7200.11's instead.
I need 4 PATA ones for my RAID 5 array. But I ain't got $500 and even if I did, Fry's always has a limit. 
Green for the OP though.

If they don't sell out in the first day or two, they will drop the 1 per custy limit when you call them.

if you were willing to drop that kind of cash, you'd be best off getting SATA and buying a SATA RAID card to go along with it.
Great deal. In the past, as soon as I've jumped on a Fry's Seagate deal like this, they usually drop the price by $10 or update it with free shipping a a few days later. I may gamble and wait...

Can I install two SATA drives on one SATA cable?
Thank You

No. One sata drive per available sata port on the motherboard.
how exciting - we are getting close to the magical 0.10 per GB and getting 1TB drives for <$100

True. True. But would the PATA to SATA converter work with my SX4000? Hardware RAID 5 cards are mucho dinero you know.

I bet one good SATA drive will perform just as well as you old PATA drives on that RAID5 card. I'm a geek too, but unless you're doing it for redundancy, I just can't justify RAID at home anymore. Too inflexible and the performance benefit is negligible.

RAID 0 (stripping, non-redundant) will eat any standard disk access out there. Two SATA II drives in RAID 0 can see about a 50-80% increase in speed. I run two seagate 250gb drives in RAID 0 on my desktop and have been VERY satisfied with the performance bump. Unless you want to drop some dough on Raptors, RAID 0 is a great option.
Just make sure you've got a backup.
As for RAID 5 at home - as someone who just decommissioned a six disk RAID 5 array (six 250 gb PATA drives) I can say that performance, while fine is not stellar. SATA is just so much superior to PATA.
I ran a RAID 5 array because I wanted to span data across 1.2 TB of drive space while having some level of protection if one of the drives went belly up. I built this array like five years ago using a PCI Promise SX-6000 controller. (The drives were all WOOT! refurbs that I bought for $50 each back when Woot used to sell hard drives.) This type of setup doesn't make sense though in the era of cheap 750 and 1tb SATA drives. When I shut down the array I replaced it with two 750gb SATA drives ($99 at Newegg - slightly better deal than this) and then shoved four of the 250 PATA drives into a four IDE USB enclosure - I use this as a back up for critical data.
I agree that the guy talking about buying PATA drives for his array should spend his money elsewhere.
RAID 0 for most users is just stupid. Particularly software-based RAID. The speed increase is marginal at best. Some people quote benchmarks that just don't represent the real world.
I tend to think of anyone who advocates RAID 0 for home users as being an amateur. It's like the guy that spends $80 on an air filter that supposedly ups his Ford Focus's HP by 5. Nobody who actually knows what they're talking about and has real-world experience will recommend it. RAID 0 for the home user is pointless. RAID 0 for most applications is pointless.
I used to support high-end workstations in time-critical production environments. We had to use RAID 0 in order to get the throughput we needed on top of the line SCSI drives. I'd estimate that 20% of the customers had a RAID failure during their ownership of the product. Using low-end hardware and software driven RAID schemes certainly isn't going to improve upon that. Anyone who says otherwise hasn't lost their data--yet.
Setting people up for failure is just bad advice. Anyone who does that should be treated with extreme skepticism--they don't know what they're talking about.
As for the price on the drives, it's not all that exciting. $110 is about what I'd expect to be paying for them. When the TB drives get to $135-$145, then it'll be time to buy again.
last weekend i bought 2 1tb seagate drives on fleetbay for $138 each after 25% CB, now you can get the same one for less than $150
enlighten me please, Why is buying 4 of these PATA for my raid 5 array at home a bad idea? I use it for backups, mainly redundancy, with my buffalo terastation. Replacing the 250 GB drives with 750 GB PATA drives increases my backup by 3x. That seems pretty good. Is it better just to buy a SATA array for the speed?
THX

THX I know I would recommend SATA for speed but if you don't care that is up to you and there is nothing wrong with that.
whodini,
Four PATA drives in your NAS will not outperform a new SATA 300 II drive with Native Command Queuing (NCQ) and multi-threaded read/write and optimized look-ahead algorithms running on a system configured for AHCI. But as purely a backup solution, speed isn't a critical issue.
There are applications when RAID isn't preferred for performance. In my primary workstation, I have a 500GB OS drive and two 1TB SATA drives. I am editing video files, reading them from one drive/bus and rendering them to another drive/bus. Without spending a fortune for true hardware RAID, It works out faster than doing all the I/O on a single RAID 0 array. My backup device is a low-end P4 in my garage which gets synchonized during downtime. Like you, the throughput for my backup device is not critical, so I have the drives sleep whenever they can.
If you've got a solution that works for you, and you have a need to backup 2.25TB of data, then by all means get four 750GB PATA drives and stick with your system. Or three 1GB drives would cost the same, giving you 2TB now and you could add a fourth later on for 3TB (I'm assuming you're RAID5), if your NAS lets you extend an existing array.
I am that guy talking about buying PATA drives for his array, but I never talked about actually buying the drives. BUT, I am stuck with a SX4000 hardware RAID. I run freeNAS to redundancy. I do NOT want to lose that data and currently, I am running 4x160 GB Seagates. I fire up the machine, move the backup to it and power it down about weekly. I don't care about performance. BUT, that said, PATA drives are getting rarer by the minute and I am not that inclined to sink about $100 extra on a hardware SATA RAID card. So, would using a PATA to SATA converter and using SATA drives help? Currently I don't have money for any drives but I see a very good discussion going on so if you SATA promoters could tell me if it is wise to slap on a SATA converter on my current PATA H/W RAID card is a wise thought, it would be great.

I am not in it for Performance. All I need is the redundancy that RAID 5 brings to the table. It can take its own sweet time writing/reading data for all I care. I just don't want to lose the data like my prior post says.
