WD Raptor BEATEN!

The new Western Digital Caviar WD7500 hangs in there with the WD Raptor, which despite having a 10,000 RPM spindle is no longer faster than the WD7500's 7,200 RPM in transfer rates. The WD7500 makes great strides forward in other technical areas, too.

Except....

Quote:
Even the median value of nearly 75 MB/s is on a par with that of the 10,000 RPM Raptor drive WD1500, and its minimal transfer rates clearly trump those of the competition. However, it still cannot beat the 74 GB version WD740. Because slower rotation speed translates into longer rotational latencies before actual data access begins, the average access time of 13.3 ms also can't really keep up with the 8 ms posted for the WD Raptor. Beyond that, however, the rest of our benchmarks should give WD plenty to cheer about. In particular, the I/O performance in the file server and database server schemas is noticeably superior to that of other 7,200 RPM drives.

So? Segate Barracuda's can beat Raptors. In fact, Seagate just launched 7200.11 drives and I bet Raid-0 7200.11's (with 32MB of Cache each) could eat Raid-0 74GB WD Raptors.

Still, nothing can compete with seek times of the raptor.

32MB cache means nothing for a single user desktop PC. You get around 1-2% performance going from 8MB to 16MB.


Raptors still win in random access.

That's not a misleading title or anything

"Because slower rotation speed translates into longer rotational latencies before actual data access begins, the average access time of 13.3 ms also can't really keep up with the 8 ms posted for the WD Raptor"

Edit: To Ninja-Boy: You're claiming that Barracudas beat Raptors in what? Overall throughput sure, but not real world performance. It's been shown over and over.

Raptors still win in random access.
But the 7200.10's already beat the Raptors in benchmarks and applications. So, with more cache and new technology these new Seagate Barracuda 7200.11's will likely the king of hard drives.

No, the Raptors aren't beaten in applications. Start a thread and we can show this.

I already stated how more cache won't help you. Go check the 7200.10 8MB vs 16MB reviews. Look at the massive difference of a 1-2% percent. Adding more cache won't help a single user on a desktop accessing data nearly sequentially.
