Chapter 9: Adding Storage with a Hard Drive (Hospedaje web gratis)
Chapter 9: Adding Storage with a Hard Drive 113 SATA (Serial ATA): The newest incarnation of the IDE/ATA drives, these offer still greater performance. Older drives moved information to your computer through awkward, stubby ribbon cables. SATA drives transfer their information faster through sleek, thin cables that route through your computer s innards more easily. External SATA: You guessed it, external SATA drives live outside your PC and plug into special eSATA ports you can add to your PC. SCSI (Small Computer Systems Interface), Fast Wide SCSI, Ultra SCSI, Wide Ultra2 SCSI, and more: Pronounced scuzzy, this popular drive variety worked its way into the hearts of power users and network administrators. Today, SATA is slowly pushing SCSI away from even those folks. Speed and space The following terms appear on nearly every hard drive s box to help you find the drive with the size and speed you need: Capacity: The amount of data the hard drive can store; the larger, the better. When buying a new drive, look for something with 50 gigabytes (GB) or more. Always buy the biggest drive you can possibly afford. Access or seek time: The time your drive takes to locate stored files, measured in milliseconds (ms). The smaller the number, the better. DTR (Data Transfer Rate): How fast your computer can grab information from files after it finds them. Larger numbers are better. Data transfer rates are broken down into burst and sustained, each described next. Burst/sustained: These figures show how quickly your computer grabs and delivers information from your hard drive. The burst rate determines the speed at which your computer can fetch one small piece of information from your hard drive. The sustained rate, by contrast, refers to how fast it constantly streams data fetches a large file, for example. Naturally, burst rates are much faster than sustained rates. 5000/7200/10000 RPM: The speed at which your hard drive s internal disks spin, measured in revolutions per minute (RPM). Bigger numbers mean faster and more expensive drives. (For some reason, techies leave out commas when discussing RPM.) When you re purchasing a drive for everyday work or sound/video editing, buy a very fast one. If you re looking to simply store large amounts of data, such as MP3s, videos, text, or similar items, save money by buying a slower drive.
