Case in point: Barracudas XTs are cheaper, have less throughput speeds than the "plain" Barracudas. Why bother with that? Since the 90s a hard drive either arrives dead mishandled , crashes within a month sloppy QC or last for years.

Higher areal densities make more data available over shorter physical distances, helping to improve performance with sequential transfers.
Seagate used to cover all its internal hard drive products for five years, but the longer term is now restricted to its premium and enterprise-class hard drives. Problems with an initial version of the chip forced motherboard makers to drop it from their first wave of Pbased offerings.
The has already found its way into a batch of refreshed P55 motherboards from Asus and Gigabyte. The latter has updated its entire P55 line with new revisions that feature the Marvell chip.
Asus has been somewhat more conservative, rolling out the in a couple of models, including the P7P55D Premium. Another curiosity associated with the Marvell controller is that its latest 1. That seems like an odd sort of thing to do, given how aggressively Windows preemptively populates system memory on its own, but Marvell claims Intel and JMicron use the same technique in their drivers.
Write-cache buffer flushing forces applications to wait for data written to a drive to make its way through the cache and onto the platter, where it will persist in the event of power loss. We re-tested the XT using the latest firmware and the recommended driver config, and our results barely budged. With the exception of our power consumption and noise levels, all tests were run at least twice, with the results averaged. We used the following versions of our test applications:. Vertical refresh sync vsync was disabled for all tests.
All the tests and methods we employed are publicly available and reproducible. If you have questions about our methods, hit our forums to talk with us about them. WorldBench WorldBench uses scripting to step through a series of tasks in common Windows applications.
It then produces an overall score. WorldBench also spits out individual results for its component application tests, allowing us to compare performance in each. Boot and load times To test system boot and game level load times, we busted out our trusty stopwatch. Our test system boots just a little bit faster than with the Barracuda XT than with the Caviar Black.
Our drive and controller configurations run neck and neck in our level load tests. File Copy Test File Copy Test is a pseudo-real-world benchmark that times how long it takes to create, read, and copy files in various test patterns. To get reliable results, we had to drop back to an older 0. During our initial testing, we noticed that larger test patterns tended to generate more consistent file creation, read, and copy times.
For our tests, we created custom MP3, video, and program files test patterns weighing in at roughly 10GB each. The MP3 test pattern was created from a chunk of my own archive of ultra-high-quality MP3s, while the video test pattern was built from a mix of video files ranging from MB to 1.
Even with these changes, we noticed obviously erroneous results pop up every so often. Additional test runs were performed to replace those scores. The Barracuda XT and the Marvell 88SE get along quite nicely in our real-world file creation tests, sweeping all three. Interestingly, the Caviar Black runs slower on the Marvell controller with two of three test patterns. The best or worst of both worlds, our copy tests combine read and write operations. That combo suits the Marvellous Barracuda duo, which is just a little bit faster than the Caviar Black on the same controller.
When using the P55, the XT is quicker than the Black through two of three test patterns. Then again, these configs are barely registering on the CPU utilization scale with our eight-thread Core i7. The Caviar Black achieves similarly impressive burst speeds when connected to the Marvell, though. Perhaps more relevant are the burst speed results from our P55 configs.
Drives were run with the PCB facing up. Our noise level and power consumption tests were both conducted with the drives connected to the P55 rather than the Marvell controller. Power consumption For our power consumption tests, we measured the voltage drop across a 0.
We were able to calculate the power draw from each voltage rail and add them together for the total power draw of the drive.
The Barracuda draws slightly more power than the Caviar at idle, but nearly three watts less under our demanding IOMeter load. A pretty decent hard drive, as it turns out. The Barracuda offers solid performance overall and slightly faster real-world read and copy speeds than its Caviar rival.
The XT is a heck of a lot quieter, too, generating less noise while seeking than the Western Digital drive does at idle. Slow seeks have been a hallmark of recent Seagate drives, including the two-platter Barracuda Seagate does expect Newegg to have drives this week, though.
Should you buy one? A good hardware controller with cache can greatly minimize the impact. If the Seagate has AAM enabled then that can also explain the big difference in seek times. It is a huge chance that no one should take. Even one hour is all it can take to lose millions of dollars. Our company has the habit of replacing HDD every year.
If the system is set up right, you know everything that is going on with the server at all times. In fact, we have it hooked up that pagers go off if a drive fails.
Of course, we did this cuz of a catastrophic failure a few years back and we have refused to ever pay that price again. An 8 hour loss of data is huge. You would risk being fired unless the boss really liked you. Now if you are doing a real time backup. You would be doing RAID 1 by proxy, only in software which is slower and you take a much larger performance hit compared to if you had a card that did it natively. Not if the parity calculations fail.
