Samsung SSD 840 EVO
The Samsung 840 EVO solid-state drive offers excellent overall performance, spacious storage, and convenient software, all for a great price.
The Samsung 840 EVO is a fast SSD that offers high storage capacity for a limited cost. This is one of the first consumer models to offer a capacity of 1 TB.
There are three essential criteria to consider when buying a SSD: capacity, performance and price. The new Samsung 840 EVO makes the choice easy since it is good on all three tables, and even on others.
This new disk replaces the first generation “entry level” of 840, but all that remains of entry-level is its price. His performances are excellent. It is the first consumer SSD to reach the capacity of a terabyte. What’s more, it comes with interesting software that can boost its performance.
If you are looking for an SSD to improve the performance of your PC or increase its storage capacity, it will not disappoint you.
The new Samsung 840 EVO takes the design of the previous generation, but now sports a dark gray hue. The disc uses the most popular 2.5-inch format and has a standard SATA 3 connection at 6 Gbps. It also works with previous versions of SATA.
This disc is available in five capacities of 120 GB, 250 GB, 500 GB, 750 GB and 1 TB. All versions come with Samsung Data Migration and Samsung Magician software. The first clone a disk to transfer its contents to another disk without having to reinstall the operating system and software. The second offers a set of utilities to optimize the disk.
It is therefore easy to clone the SSD of a computer to the 840 EVO without buying additional software. Both programs are delivered on a CD but can also be downloaded from the Samsung website.
Practical Software, Flexible Configuration
The 840 EVO does not come with a boost function directly enabled, but you can do it through the Samsung Magician software. This is to use some of the free storage space to improve disk performance. This allows you to choose between maximum performance or retained capacity.
The Samsung Magician software also makes it possible to check the good behavior of the disc, to completely erase certain data it contains or to adjust the operating system so that it uses its operating speed as well as possible.
A number of features allow the 840 EVO to be fast. First, the Samsung Magician software has a new feature called Quick Mode, which can be turned on and off with a single click. When enabled, it appropriates part of the computer RAM as if it were its own cache memory to increase its performance. Depending on the available memory, it can use between 500 MB and 2 GB. The tests performed show that this fast mode significantly improves the performance of the disk.
In addition, at the hardware level, this new drive uses an enhanced version of the Samsung MEX controller, based on the triple-core MDX controller used in the 840 Pro, as well as NAND Flash Toogle DDR 2.0 memory. The Samsung 840 EVO also has a new firmware that can boost significantly its performance compared to the 840.
Finally, the 840 EVO has a new technology called TurboWrite, which, depending on the capacity of the disk, can double or triple its sequential write performance compared to the 840. To gain speed, the data is first written in the buffer then moved to the storage regions of the disk when the disk is idle. In normal use, an SSD is inactive most of the time, this TurboWrite function is very effective.
For even more optimized performance, it is recommended that you use this drive with an operating system that supports the TRIM command, that is, from Windows 7 and Mac OS X 10.6.
Functions And Performances
Equipped with the Samsung 840 EVO, our test computer only needed ten seconds to boot and about five to shut down. The disc also allowed him to wake up almost instantly. The launch of software, especially heavy programs such as games, was also faster than when the computer was equipped with a traditional hard disk.
The 840 EVO delivers superior write performance in reading at a write speed of 267 Mbps and a read speed of 184 Mbps in a basic data copy test. When used as the primary disk hosting the operating system, simultaneous write and read operations of small files were performed at a speed of 257 Mbps. These performances were boosted by Fast Mode, reaching 289 Mbps write, 193 Mbps read and an impressive 378 Mbps for writing / simultaneous playback.
This new SSD also improves the battery life of a notebook. With our machine, we found a gain of twenty five minutes compared to a traditional disc 7,200 revolutions / min.
With its good performance, affordable price and 1 TB storage capacity, the Samsung SSD 840 EVO has everything you need to make a good internal storage device.
