Neat!

My first thought was - "I wanna work on one of those"

Well, you say all that, but if I do the same operation using the CLI 
instead, it's instantaneous. Clearly this is just another instance of 
Windows Explorer being retarded. (I know on many computers, Explorer 
uses more RAM than any other process. WTF?)

Dude... where do you even buy that much disk space??

My PC has *four HDs* in it and it totals less than 300 GB!

Neat. Your laptop has more HD capacity than my entire DB server. (BTW, 
how the heck do you put *two* HDs in a laptop??)

Well, the "backup" part is just a file copy. The database generates 
roughly 10 MB of log per week, so I doubt the running Oracle process 
slows the copying down significantly.

The copy is from disk to same disk, and the "disk" is actually a RAID-5 
array of Ulta320 SCSI drives. IIRC, it's 4 x 36 GB for a total of about 
108 GB. (It's partitioned into two NTFS partitions. For no particular 
reason. That's how the expensive Oracle consultant set it up...)

It came that way.
Some of the more high-end models do, since the laptop-size drives are more 
expensive and lower capacity than the desktop drives.
It's a 17" notebook, so there's lots of space.

OK, that's pretty impressive. Does it have RAID capability in hardware?

Also, does it have hardware 3D acceleration? (I still can't believe you 
can get that in laptops now...)

I've only ever looked at really cheap laptops. *My* laptop is powered by 
an AMD AthlonXP 1700+. (Mind you, it's rather old now...)

I do hope it was gold-plated.

I paid R750 8 months ago for a 320GB drive. At the exchange rate of the 

And SA is more expensive than the UK for computer stuff.

SATA-II. Does that count?

No. It's still a notebook. Even my desktop doesn't have true hardware RAID. 
The motherboard drivers support RAID, but I wouldn't call that hardware.

Yup. It's got a GeForce 7600 built in.
