Western Digital combines SSD and HDD

Previous hybrid hard drive has given the producers a few flash GB. The behavior of the user is copied to the most frequently requested disk sector analysis, the memory buffer is filled in automatically controller. Data can be requested by the operating system and then read from the cache, run applications faster than traditional disk faster.

However, the full SSD performance did not reach the previous hybrid disks because they only hold 8 GB cache and therefore must continue to frequently download data from the disk. Acceleration effect is only a buffer optimization algorithm works. Therefore, many countries want to mix hard drives and more memory, its contents, he can determine himself.

The request hope from now on use the Western Digital WD Black 2 dual hard drives (WD100106XDTL). This is a 2.5" hard drive with 9.5mm height, SATA 6G interface and 5400 rev / min. Except one from the 20 -nanometer manufacturing TB storage capacity of 120 GB containing magnetic and MLC NAND flash memory.

In the delivery state, the plate is the first 120 GB SSD identification system. Magnetic part of the drive will not appear until the operating system is loaded and installation of other software after the second partition. So SSD and hard drive partition can fill in any and partitions.

Restrictions

However, there are some limitations. WD drives offer applies only to Windows XP or later, Mac OS and Linux are excluded. Not even support dual boot. Two memory areas between the dual- drive cross- partition is impossible, it is also applicable to other disks in the RAID neither nor as part of the storage space. In addition, WD said incompatible storage controller driver Nvidia and ASMedia and recommended no data on the disk, the magnetic portion of the transmission as the Acronis True Image program.

When the range of SSD 's visit, the WD Black 2 data speeds of up to 350MB /s read and write speed 140 MB/s. Estimated by the manufacturer to 0.9 watts and read and write power consumption of 1.8 watts - whether this applies only to the field or while rotating disk SSD is unclear. If the flash memory fails, the magnetic part of the disk to keep addressing.

WD awarded five-year warranty and is called the suggested retail price of 330 €. In order to make WD Black 2 GB neglected to triple your conventional hybrid plate and cost considerably more than the combination of separate SSD and hard drives with the same capacity. Interestingly, so it is best to replace the traditional hybrid drive laptops and mini-computer has only one hard drive bay.
