I would recommend this to everyone looking for a performance boost and not looking to buy a new computer. They make use of the 4GB of flash with a technology called Adaptive Memory. The drive has the standard Seagate drive appearance with a simple all-white label on top of a minimalistic silver cover and black metal body. The performance benchmarks outlined in this review can be categorized into two sections. This score was still well above any of the previous notebook drives, showing some caching midway through the test. In our IOMeter and CrystalDiskMark tests you will only see raw performance, which normally might translate into real world scenarios.

Build quality is good for a consumer notebook drive.

Seagate rates the operating shock at G, meaning this drive can survive a pretty good impact like what you might experience if you drop your notebook. Also, for some reason, expect that once you install the hard drive and boot it up, it takes reboots to get the best performance. To the naked eye nothing about this drive indicates that it is unlike any other notebook drive on the market.

Only idiosyncracy I have noted. Upon first startup I noticed no difference, but after a short time my laptop started turning on MUCH more quickly i. The Seagate Momentus XT is an excellent notebook hard drive and under the right circumstances surpasses drives well out of its class. Also, it was easy to install.

Overall the Seagate Momentus XT makes the most sense for a anyone who just wants a noticeable increase in notebook performance, while still getting capacity without a huge jump in price. With this increase it still falls behind the latency of the Western Digital Scorpio Black and well under the Velociraptor.


Since each test includes normal system activity that has some repeating patterns, this lets the SSD module inside the XT actually do what it was designed to do.

As you’ll see momentarily, hard drive benchmarks which utilize synthetic data are completely uninfluenced by Adaptive Memory. Samsung ZET Review.

In this trace we recorded 2,MB being written to the drive and 1,MB being read. Big improvement in my macbook’s startup time for a good price. It’s s great way to lengthen the life of moderately old to older systems. Don’t get monentus wrong, it works on the first reboot but it gets better after two or three.

In some cases we have seen drives perform exceptionally well in transfer speeds but plummet when it came to our real-world test. It is incredibly fast and responsive.

News Reviews Insights TechRadar. With 11 ms read seek time and 13 ms write seek time, this System hard drive offers faster command processing. 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 momehtus.

Looking at the circuit board we can also see that both drives use the same HDD controller and motor driver. To see peak performance through the caching mechanism we looped the benchmark four or five times in momentuz before the speeds leveled off. Specific examples of where this comes in to play include things like FAST Boot, where Seagate has portioned off a portion of the Ommentus, just to handle files needed for booting a computer.

They make use of the 4GB of flash with a technology called Adaptive Memory. Normally most drives interact with both sets of benchmarks in the same manner, but nomentus Seagate Momentus XT is different.

It’s the first hybrid drive we’ve seen for years: That is where the similarities end though. Disassembly Taking the drive apart was easy after removing seven precision Phillips head screws.

Before a decent hybrid ever went on sale, solid state prices crashed and the public decided that they didn’t really care about the performance difference between traditional and SSD storage anyway. One of the most impressive feats of the new Momentus XT is how well it manages power consumption. Most synthetic benchmarks work with such random data that it defeats or greatly limits any internal caching algorithms used by Seagate.
