DAS has been widely used for decades. It is a common choice among small and medium-scale businesses. It is also increasingly popular among enterprises as well. But if you’re looking to opt for DAS when it comes to your Exchange environment, you might want to look into the many RAID array options as well as the use of multiple disks.

SANs are scalable and dependable for centralized data storage resources. They operate through independent networks and mostly use Fibre Channel based connection sin order to communicate between connected managed hosting and disks. However, they are more complicated and relatively more expensive. The software for SANs is usually packaged separately from the hardware but DAS features a range of utilities.

Finally there is the iSCSI. This is a storage protocol that can connect to a network device and move storage related data. Clients are able to send SCSI commants to consolidated and remote storage targets as efficiently as they would with a locally attached disk.

Buying a laptop? Want to upgrade your old one with a new hard drive? Besides hard drive’s space size for storing your applications, documents, music, movies and other data, you should also pay attention to its speed performance. If you want fast access to stored data on your laptop’s hard disk, you should purchase hard disk with SATA interface, higher rotational speed and larger buffer cache size.

Buy Laptop with SATA Drive

Serial ATA (SATA) hard drives use less power, so they save your laptop’s battery. But, they also enchase your laptop’s speed performance. Most hard drives usually support ATA/66 (66 MB/sec), Ultra ATA/100 (100 MB/sec), or SATA (150 MB/sec) interfaces. The numbers refer to the maximum burst rate at which the drive can pass data to the system (66, 100, or 150 megabytes per second). SATA transmit data in a serially (in a single stream) as opposed to PATA or Parallel ATA which is commonly referred to as an IDE hard drive.

Check the Hard Drive Rotational Speed

Don’t forget to check the hard drive rotational speed!
The hard drive rotational speed tells you how fast the drive spins its disks in revolutions per minute (rpm). A higher rpm means higher drive performance. A 7,200 rpm hard drive is faster than a 5,400 rpm or 4,200 rpm and gives better performance.

Larger Buffer Cache Size - Better Performance

Buffer Cache Size is a temporary data storage area used to enhance drive performance. When the computer requests data from the hard disk if that data is in the cache, there is a performance boost directly related to the speed of the cache. Larger buffer cache size usually results in better hard drive performance. Buffer cache size on the most of laptop’s hard drives is usually 2 MB, 4 MB or 8 MB.
