A hard drive that is Ultra ATA 100 has a burst transfer rate of 100MB per second, in one burst, not all the time. Therefore a burst rate is a one time transfer rate of speed or one session, which is similar to a cable provider claiming 20 megabytes per second, download speeds, when the actual sustainaible rate, is far less.
When you are looking at hard drives, remember the two different types: internal and external hard drives. Internal need to be installed and are generally a little bit cheaper, at least if you do the installation. They also generally have a higher rate of data transfer. External are usually connected to your computer with a USB cord, which means they have a slightly slower transfer rate and will use up a USB port whenever you are using it. However, they are portable, so you can bring files to your friends homes, to another computer, or into the office.
access time is the amount of time required to deliver item from memory to processor. While, transfer rate is the speed with which data, instruction, and information transfer to and from a device. Transfer rate for storage are stated in KBs, MBps and GBps..etc
How quickly a drive can locate the correct track and sector once a data request has been made
E sata transfers at a rate of 300 megabytes per second and tapes transfer at a rate of up to 80 megabytes per second. E sata is by far the faster solution
It depends on the PATA drive in question. That said, the fastest UDMA interface when used with an 80-wire cable is 133 MB/s. From there, the maximum transfer rate for a SATA generation 1 drive is 150 MB/s. For SATA 2, it is 300 MB/s. For SATA 3, it is 600 MB/s.
no you do not
15 MBps to 320 MBps
7800 kB/s
The 50X maximum speed, 5.25-inch half-height form factor CD-ROM drive features high data transfer rate up to 7, 500 KB/Sec.
Hitachi hard drives are solid in quality and they make very good hard drives. The model considered by the users to be their best is the one with 7200 RPM, capacity of 1 TB and maximum transfer rate of 6 GB/s.
There are four primary types of media used for data backup. 1) DVDs - I find these tedious and space consuming but cheap and they'll do the trick. They do have the slowest data transfer rate of the possible media used for data transfer. 2) Hard Drive - Whether an external drive or an internal one docked in a "toaster" (A sata 3 docking station which allows the user to connect an internal hard drive to a different computer VIA USB so one doesn't have to physically hook it up to the motherboard) 3) Cloud Storage- Free services like skydrive or Dropbox (or icloud if you're a Mac user) are great for transferring documents between devices or to a new computer! 4) Flash media - Flash Drives and SSD Hard Drives are among the fastest ways to move data around!
