WD Black2, Hardrive Analysis

WD Black2, Hardrive Analysis
Now that the SSD are on everyone 's lips, there are companies trying to maintain as you can your business more traditional hard drives. In recent years we have seen how these devices are reaching the limit of its possibilities, so it is time to seek alternatives that can keep them alive in the market.

One is the so called hybrid discs, which generally offer a mechanical part and another in flash format. The WD Black2 is one of them, and also one of the most interesting by allowing combine the performance of a SSD with the capacity of an HDD. How is this curious mixture Behave? This is what we describe today with this analysis Black2, as always with benchmarks and comparative performance against other units on the market.

The new hybrid drive WD
The idea behind the WD Black2 is not to offer a hybrid that has a small capacity flash to act as cache mechanical drive, such as Seagate SSHD , if not proposing a double solution in a single device . For practical purposes, WD Black2 is a 120GB SSD and HDD 1TB on a single disk of 2.5 inches in size and 9.5 mm thick. A party does not act as a cache of the other, if we can not consider them as two separate units, in fact, act as two separate and distinct partitions. What we will see from the operating system is the same as if we had two different devices.

WD Black2 installation is not trivial , as if it is using a new mechanical drive or an SSD in any current operating system. The first time you connect the Black2 to a PC, it will recognize the partition of the SSD but not the HDD , which will remain hidden. To view have to install some drivers specific supplied by Western Digital and available over the Internet. Install, restart and voila, a somewhat tedious process that we already had unusual but neither is a great effort.

We have already mentioned that in practice we have two separate partitions that will allow us to play at will. We said, too, that are two units in one , it is that inside the Black2 we will find a WD Blue Slim 7 mm, 5,400 rpm, plus the necessary circuitry to add part of flash memory, according to analysis AnandTech with the respective cutting corresponds to a Micron NAND controller using its 20 - nanometer. It is also necessary to note that WD has tried to take care of the packaging and product design, the image of the user. The device is covered by a metal black layer quite striking, and from my point of beautiful view, being sold in a box large that also includes a SATA adapter to USB 3.0 and USB 3.0 memory 'role type', which contains direct access to the web and some useful software like Acronis true Image.

Test conditions
A brief description of test equipment and software used: Mountain GTM 3000, with Intel Core i7-3930K, 16 GB of RAM DDR3 and Asus Rampage IV Extreme motherboard are some of your specifications. Connection interface SATA3 directly to motherboard. Operating system Windows 8.1 Pro 64bit.

Benchmark
For the preparation of this analysis we used three programs whose use is completely free and open, which can also be easily found on the web:

  • CrystalDiskMark 3.0.1c
  • ATTO Disk Benchmark 2.47
  • AS SSD Benchmark 1.6.4237.30508


All tests have been performed with the default settings of the application. In addition, add screenshots of the results at the end of the entrance, in the gallery with the pictures of the device.

Sequential read and write
CristalMark data on default settings. In MB / s, the better.

WD Black 2: Conclusions
As you see in the analysis we have differentiated part SSD the HDD , since the end of the two partitions are those that the system creates on its own. Once again we reiterate that WD Black2 is, for practical purposes, as having a SSD and HDD on two different devices, but together and occupying a single space. Therefore, the portion SSD behaves 'almost' as a typical SSD. We say that 'almost' because the benchmarks show a good performance in sequential read, but regular in sequential write or both tests on ATTO. We should also mention the lousy read access time of both parties.

In actual use if you notice that there is somewhere SSD team. The yield is significantly higher than a HDD, and it shows when we started the system and of course at the time of application load, search and others. However, we should also mention that the set will not be as powerful as many of the current flash storage devices market, staying in a 'mid range' of SSD. As always, a comparative graph of the prices of different products that we tested at the time of each analysis. The Black2 analyzed and for now the only model available can be found for about 200 euros in the Spanish market, considering its 1.12 GB available results in the top positions:

The positive is no doubt that the WD Black2 is the best choice to combine capacity and performance in a small space. An almost exclusive portable product (desktop, usually, no space requirements for using two separate devices), and where you can have your space. It 's not the fastest, but it does. Benchmark image by; xataka.com
