1.5Gb/sec
The main difference is transfer speed, if you for instance a new solid state drive it a sat 1 port it will be limited in speed, still fast but not the maximum performance you could get out of it, For a conventional Hard drive you won't notice the difference though. All sata devices are backward compatible so theres no worries there
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.
Speed of sata 1 is 1.5 Gbps Speed of sata 2 is 3 Gbps
SATA is............. This is one of the latest and popular developments. The high speed serialized AT attachment. Currently SATA offers ransfer speeds of upto 150Mbps. However, this technology can offer upto 600Mbps with further development. The next stage is increasing the speed to 300Mbps.This is a popular term, it really should be called ATA - Advanced Technology Attachment. One of the earliest types. Also known as ATA-1. Data transfer rate of about 8Mbps (8 million bits per second). Basic differences are,1) Speed (150mbps (SATA) vs 100/133mbps (PATA))2) Air flow (large IDE cable vs thin SATA)3) Hot swappable (SATA)4) Newer technology with future speed increases promised.
1. Disk rotational speed in rpm. "HDD data transfer rate depends upon the rotational speed of the platters and the data recording density."
Hello,I've been using Kingston PenDrive (1 GB) for 2 years, and found this a very good and satisfactory product. Its data write speed is about 10 MbPS and read speed is upto 20 MBPS. So I think it's having a very good transfer speed.Goodluck.
The USB 2.0 give up to 480 Mbps data transfer speed
Factors that affect data transfer include: 1. availability of data 2. medium of transfer 3. speed of reception/transfer 4. protocols used for negotiation, amongst others
SATA 3 is backwards compatible, it means you connect it the same way as SATA 1.
Mbps is a measurement of speed. Megabits per second. 1 terabyte is an amount.
1.simple i/o: 2.programmed i/o: a) synchronous data transfer b) asynchronous data transfer c) interrupt driven data transfer 3.Direct memory access data transfer a) burst mode b) cycle stealing mode
Different data rate speed (for rs232 is lower), usb is more flexible and takes less energy. Different instructions and commands. If you are a programmer then it's easier for to work with usb then with rs232.
