Hard disk drives are today's fastest permanent storage media and have a large capacity. For this two reasons they are the most used storage medium in computers and servers. When buying a new hard disk, there are three important things to consider: - The connection of the disk to the computer or other device you will be using it with has a big influence on the speed with which data can be read from/written to the disk. Make sure the connection of the disk you buy is compatible with your computer! - The rotational speed is also important for the speed with which data can be read from/written to the disk and determines the time it takes to find a file on the disk. - Last but not least, the storage capacity of the disk, i.e. the amount of data that can be stored on the disk.

Most of our avid readers of course have at least one SSD in their desktop and laptop, but for large volume storage you're still relegated to conventional hard disks. It's almost become a negative connotation - 'conventional' - and it really doesn't do t...

It truly amazes me on the capacity and speed that hard drives have evolved into over the years. I remember not so long ago the large 3.5" drives with the IDE cables that took up so much room in the case. Let alone the limitation on only four IDE devic...

Bottom line The Seagate Momentus 7200.4 drive performed very well throughout the testing. The drive even gave the bigger brother the 3.5" Seagate 7200.11 drive a run for its money and even beating it out the majority of the time. The overall read and write speeds...

The Seagate Momentus 7200.4 (ST9500420AS) is a 500GB 2.5in hard drive with a spin speed of 7200rpm and a 16MB cache. Despite being small enough to fit in a laptop drive bay it is faster than many 3.5in hard drives designed for desktop PCs. The Seagate Momentus 7200.4 is faster than 5400rpm laptop drives weve tested, such as the Western Digital Scorpio Blue (WD5000BEVT) and the Seagate Momentus 5400.4 250GB (ST9250827AS). This was shown in our transfer tests. We copied 19.4GB of files from our...

Bottom line The Seagate Momentus 7200.4 (ST9500420AS) is a laptop hard drive that offers faster read/write speeds than many larger desktop hard drives. If you need a fast and cool hard drive for laptops, media centre PCs or network-attached storage (NAS) devices...

It also has a double amount of cache (16 megabytes) compared with its cousins that have slower platters. The Seagate website announces a 750GB model already which seems to hail from a whole new series that, like the junior one, lacks an ordinal number in the end of the name. Unfortunately, we...

Seagate Momentus 7200.4 500GB - We're at a loss to explain how this 7200rpm drive can be quieter than the 5400rpm Momentus 500GB with the same number of platters that we reviewed in the spring. Perhaps one or both of our samples are atypical — it's hard to say one way or the other without a...

Bottom line I really went into this skeptical, I promise I did. But I’ve been using this drive daily for weeks, and I just can’t find a single weak spot. The only thing I can come up with is a slight increase in susceptibility to gyroscopic effects over...

Bottom line As we can see from our testing, the new Seagate Momentus 7200.4 500GB packs quite a punch compared to the slower 5400.6 Momentus, even approaching desktop drive speeds. It would appear that Seagate isnt going to go down without a fight, giving consu...

Bottom line We found the Seagate Momentus 500 GB 2.5 inch (7200.4) to be a great upgrade to what had been the questionable purchase of a POS Toshiba laptop. Previous to the Seagate Momentus we were using the laptop but not entirely happy with its performance. Ha...
