You combine your advantage of the compact structure and a decent memory capacity and speed. We can offer our range not only simple SATA hard drives with different storage capacity, but also various SAS drives for servers, as well as used SSD hard drives.

pros and cons of 2.5 inch disks

power consumption

Due to the small size of 2.5-inch hard drives can generally be operated with a power supply of about 5V. This not only in notebooks and other mobile devices for more battery life, but also allows operation via the USB port when the volume has been mounted in a hard drive enclosure.

variety of interfaces

The hard drives are connected today, as in the 3.5-inch version, on the SATASchnittstelle, since this is a widely used standard now. Older models are operated via IDE, bearing in mind here that the IDE connector of a 2.5-inch hard disk is different from a 3.5 inch hard drive since been integrated additional wires for the power supply. For SATA, there is this problem does not, however, so that the same cable and adapter can be used. Models with SAS interface for working on the server also available, which allow a higher data rate and are therefore suitable for professional use within the company.

variable sizes

The dimensions are officially defined and are 70mm in width and 100mm in depth. However, an amount of 5 to 15 mm is possible. Established had here over time 12.7 mm, where there are currently models with a height of 5mm, 7mm and 9.5mm. This is mainly due to the very flat terminals (such as Ultrabooks) in which they are used. So if you own such a device, which allows only certain sizes, you have to bring it into experience before replacing the hard disk. In addition, some manufacturers used in very thin disks, a special connection, in this case with caution.

speed and memory

In this respect, are the disks, in comparison with the larger models, hardly at a disadvantage. Only those who really needed a lot of storage capacity (more than 2 TB per disk) has 3.5 inch hard drives better advice or even has to resort to this. Otherwise, only the slightly higher price is a small drawback in view of the many advantages but is vanishingly small. In addition, especially the 2.5-inch SSD hard drives are unbeaten in terms of speed.
