Seagate has yet to put out a consumer-class solid state drive SSD , so this is its closest attempt to hit the attributes that have made SSDs popular in the last couple of years.
The first attempt failed miserably. Seagate had placed its marketing bullseye on power savings, not performance. The fact is, even a full-fledged SSD doesn't deliver power savings for consumer-type products that's worth writing home about, so charging extra for the Momentus PSD didn't go over well.
Oddly, Seagate never offered its own benchmark test results on the Momentus XT when it arrived. It does come close to today's fastest hard disk drives for read speeds and it beats them -- as well as some SSDs - on write performance -- and, more importantly, on price. For my tests, I used a Dell Latitude D laptop with a 2.
I load a full compliment of applications on the laptop, such as Adobe Photoshop, AOL Instant Messenger, Windows Office Professional and Excel, along with a slew of file folders, in order to add reality to the test bed. Mark Wojtasiak, senior product marketing manager at Seagate, said the company's own tests showed that their Momentus XT boots within five seconds of an SSD's boot time, and is 15 seconds faster than Western Digital's GB Velociraptor drive. That statement is accurate.
I found the boot-up time for this drive pretty impressive - 18 seconds. But it lagged on reboot, which took 43 seconds. Overall, though, these times compare favorably with other SSDs and hard drives I've tested see results below.
The one key takeaway from Momentus PSD Seagate learned from users was that if we were going to put SSD on a drive, customers better see the performance benefit. Otherwise, there is no real advantage to the technology. I think Seagate got it right with Momentus XT…just look at the benchmarks and reviews. All data is written to the disk first.
The Adaptive Memory Technology analyzes what bits of data are used most for boot, application load, etc and mirrors just those files to the SSD. I hope this adds some clarification…thanks again! Looks like a no-brainer Share […]. I had to seek the answers from our security experts here seagate. This is what I was told: There are two questions here:. How does AMT play with encryption? Normally most drives interact with both sets of benchmarks in the same manner, but the Seagate Momentus XT is different.
In our IOMeter and CrystalDiskMark tests you will only see raw performance, which normally might translate into real world scenarios. Switching to an even smaller random transfer test our next IOMeter benchmark measures the random 4K read and write speeds of each drive. The closest drive managed just 0. With an incredibly strong lead in random 4K write speed, the GB Momentus XT had no trouble nearly halving the average write latency compared to its competition.
Its peak latency scored towards the bottom of the chart with Our next set of synthetic benchmarks look at the inner and outer edge performance of the GB Seagate Momentus XT, with the outer edge being fastest and the inner edge being slowest. This is a good example of best and worst case performance, since depending on where the data sits on the rotational media it could be in an advantageous or unfavorable position depending on file system or partition layout.
This gets closer to what you might see in the real world, although the data is still far from what you would see in practice. The Momentus Xt GB showed very promising results across the board, in some cases having almost triple the speed of the comparables.
If you are new to StorageReview, one thing we try to focus on is how any given drive might perform under real-world conditions. For the average user, trying to translate random 4K write speeds into an everyday situation is pretty difficult. For this reason we turned to our 4K-optimized StorageMark traces, which include HTPC and Gaming to help readers find out how a drive might rank under their conditions. In this trace we recorded 2,MB being written to the drive and 1,MB being read.
Our next real-life test covers disk activity in a gaming environment. Unlike the HTPC trace, this one relies heavily on the read performance of a drive. The trace captures the heavy read activity of each game loading from the start, as well as textures as the game progresses. In this trace we recorded MB being written to the drive and 7,MB being read. When comparing drives used in a mobile platform one of the biggest selling points is low power consumption.
With chipsets becoming more and more efficient, key sources of power draw get narrowed down to either the bright screen or the storage device used. In the next test we record the average power consumed over a small range of synthetic benchmarks. For reference, Seagate lists an average idle power rate of 1. The Seagate provided power values came in spot-on in our tests, with our actual idle rate measuring just 1. This value was seen right after the drive parked its head.
Active power values ranged from 3. Startup power requirements neared almost 1A, measuring 4.
