Gotta love marketing folks. It looks like it might just be funny accounting, or a typo.

WD calls the new Raptor a 150 GB hard drive, but in the specifications (http://www.westerndigital.com/en/products/Products.asp?DriveID=190) list it at a formatted capacity of 150,039 MB. That works out to around 157 billion bytes (150,039*1,024*1,024), which, in Dell's parlance of 1 GB = 1 billion bytes, is 157 GB, which rounds to 160 :)
 
They are probably using two WD800GD's in RAID-0 to get that figure.

The WD740GD actually has 40GB platters, but the last 3GB are short stroked off to raise minimum transfer rates, bring their capacity inline with SCSI competitors, and make the drives look better in canned benchmark reviews.

WD released a WD800GD which takes full advantage of the 80GB platters, with slightly lower inner zone transfer rates, but the slightly higher capacity, to "select OEMs." Dell is one of those OEMs.

Of course, we all know the WD1500ADFD would be faster, but it's not RAID-0, so it can't be hyped as much :rolleyes:

I somehow think that you are spot on, considering it says "raid-0" in the OP's quote.
 
This is also similar to them rounding the 74GB raptor to 80GB. Pointless IMO because anybody who is even looking to buy that computer knows that the only SATA 10K HD is the raptors and they come in 36.7, 74, and 150.

Even though it says it is it doesn't make it 80. When I bought my "40" GB HDD off the internet, it wasn't really 40 gigs like it was advertised. :(

Read. There's actually an 80 GB Raptor, believe it or not. I don't know *why* there is - I'd imagine it's slower, and that defeats the whole point of the Raptor - but it does exist, and it's a different beast from the 74.

This last sentence is incorrect. The WD800GD has the exact same actuator, firmware, and platters. The only difference is the extra 3GB zone at the end of each platter and the lack of a warranty from WD (It's an OEM/builder only drive). Seek times are the same, transfer rates through the first 70 binary GB are the same, etc.

Yes, but not sectioning off that extra 3GB means the head has to seek just a little farther in the average case. I think. NTFS may be smart enough to keep it defragmented enough that it doesn't make a difference, but it has the potential to slow the drive down just a little bit. I'm not saying it's a lot slower, just a potentially benchmarkable difference.
