Discs SCSI need a special controller so that they work. If, a disk drive SATA or LEG will directly connect to the motherboard of PC, this type of needs require a controller it makes so that it work. Both offer a fast data transfer, but models SCSI turn to a faster rate and therefore he is faster in the shipment and reception of data. It is very common to find a hard disk SCSI in a servant instead of a PC. Their majors data rates and capacities of correction of make them to errors perfect to use like part of a disc set. Although type SCSI is considered more trustworthy, but also they tend to be worn away more express due to the high speed that the discs turn. SSD (Solid State Drives) Solid state, is an used term to talk about entirely to electronic components construdo of semiconductors. Emmanuel Faber addresses the importance of the matter here.

In simple terms? The SSD undoes of the magnetic storage ( disc that we saw in first) to occur a solid storage, without movable parts. In fact, the SSD and our typical memory USB share many similarities, because the storage Chips that they use are the same or very similar: the difference is in the form of the disc (adapted to the present ones of 2,5 or 3,5 to be able to fit in, for example, one laptop), and in the capacity. Now, although we are in a stage in which the SSD are still too expensive in comparison from old technology, with the fast fall of the multiplication and production cost in storage, I I am of whom thinks that it will not spend long time more, so that the SSD are common thing. They only see netbooks, because in many these, it is decided on this type of storage, instead of traditional hard disks. SAS (Serial Attached SCSI Drive) (Serial Attached SCSI or SAS). Technology of bus of computers designed mainly for data transfer from or towards storage devices (like hard disks, units of CD-ROM, etc.). The successor of the parallel SCSI considers itself.

The main difference with its predecessor is that it uses serial transference of data, increased the speed to 1.5 – 3 or to 6 Gbps. It allows to major speed in the data transfer, connection in the heat of the moment, has compatibility with hard disks Serial ATA because they use the same connector (however a Serial ATA controller does not recognize hard disks SAS). SAS supports a high number of connected devices, in theory more than 16,384 devices. However the parallel SCSI is limited 8, 16 or 32 devices. The SAS especially are used in servants who need high productivity.
