Answer 1

              SD stands for Solid State Drives and storage device is built on flash memory technology. It is often misleadingly called the disk did not contain any disk.HDD stands for Hard Disk Drive and a storage device is built on technology platters (disks) coated with magnetic material. Durability.SSDs are much more resistant to vibration than traditional hard disks because they do not contain mechanical parts. Their resistance to shock is much greater than the HDD. They also have greater resistance to temperature changes. But in terms of processes, delete and write winning HDD - the flash memory cells have a limited life when it comes to erasing cycles, SLC-type cells (store one bit) is about 10 times more durable than MLC (store more bits) - from about 10 000 to about 100 000 cycles reset. Energy consumption:SSDs consume less power than HDD, but the difference is so small compared to other computer components that paying attention to it only makes sense in portable computers - SSD will extend battery life.

              Connecting to a computer in both cases is the same, problems can arise when you try to "land" the drive (partitions). In the case of traditional hard drives can cause problems even at the very creation of the partition. The problem concerns the large hard drives, in which sector (the smallest unit of physical disk space) is larger than 512B. Only the newest systems (Vista, 7, the latest Linux distributions) and the latest partition managers cope with such disks. If you install XP, or we have to insert the jumpers, or downloaded from the manufacturer of special software for partitioning. In the case of SSDs is generally a complex problem because the flash memory erase entire blocks (rather than individual cells, hence the name flash - one pulse clears the large amount of data), can not directly save a cell (as is done HDD) - first must erase them (more precisely their entire block). This not only complicates the procedure for recording but also the partitioning. Windows 7 can recognize the device SSD defrag off for him and creates consistent with the size of the block partitions. Vista and XP sees the device as a normal SSD hard drive and optimize the terms of use SSD (defragmentation is not only unnecessary but even harmful (!) - Reduced cell viability, uncompensated partition of the block boundaries results in decreased performance - sometimes by more than 50 % - and unnecessary reset operations).

               Summary:If the key is the power consumption, shock resistance and temperature changes - select SSD. If you want to have a large capacity at low cost - choose HDD.
