What does "1TB 7200rpm Hard Drive" mean?

memory is different than storage. Think of storage as a big filing cabinet. The bigger the cabinet, the more you can store in it. But because there is more to search through, the longer it takes to look through all the stuff, the longer it takes to rearrange the contents of the cabinet and the more you lose if you lose access to the cabinet. a1T holds more than many other common sizes. If you store alot of music or movies, from a secure source, the larger size might be better. BUT if you are getting those same movies and music from the internet, it would NOT be a good thing. IF you get music or movies from the internet, you would be better with two medium sized drives and keep unsafe music and movies physically separate from your good data. In general larger drives are LESS reliable than smaller drives.

7200 is the ROTATIONAL speed of the drive. The larger the drive, the more likely you want it to rotate quickly to reduce "seek", "read" and "writes" times. 7200 is a middle speed. It is WAY faster rotational speed than a 5400, but slower than 10,000, In theory that would make seeking and transferring data faster than a 5400, but not necessarily. Gamers use smaller, faster drives. There is a new class of even faster drives called SSD's and they are even faster because they have no moving parts, they store info just like a flash drive.

Think of memory like "scratch paper". You use it to take a note, to make calculations, then discard it. In general more meory is better. That unit is usually configured with 6G wich is about perfect if you are using a 64bit OS (you have it), but individual retailers might have more or less.

Hard drive is the permanent storage area on the computer, it contains your operating system, programs and files. Items are loaded from the hard drive into Random Access Memory (RAM) or "memory" for short, for the processor (Central Processing Unit or CPU) to work on.

RAM is faster than the hard drive in speed, but it's volatile when the power goes off, thus the hard drive is used for permanent storage as it's larger and less expensive than RAM.

The 7,200 Rotations Per Minute (RPM) refers to how fast the hard drive platters spin, giving faster read and write speeds, gets what your computer needs in and out of RAM faster.

The 1 Terabyte refers to how much storage space the hard drive has. (alot!)

People get confused by the Megabits, Gigahertz, Megabyte, Gigabyte and Terabytes when describing the hardware features, but these are just measurements, either of speed or storage amounts.

People also make typos, for instance the abbreviation MB is for Megabyte and Mb is for Megabit, just adds to the confusion.

Learn how computers work, then you'll understand all the references and descriptions.

It means your harddrive has 1024 GB of memory

1 TB= 1024 GB

1 GB = 1024 MB

1 MB = 1024 KB

1 KB= 1024 Bytes

7200 RPM means round per minute, it means the magnetic tapes inside your hard drive can roll in the speed of 7200 RPM, more the rpm faster your data transfer rate will be

1tb 7200rpm

7200 Rpm Hard Drive

1 TB is equal to 1024 GB - this refers to storage space..

7200rpm is the rotation per minute of the Hard Disk..

1TB (tera Bytes) = 1024GB(giga bytes)

7200rpm - disk rotation speed.rpm-rotation per minute.

no it isn't.now a days many people have TBs of hard disk memory.

This is HARD DISK, not memory... Why not get someone you know and is not "computer illiterate" to help you with shopping...?

Huge memory that is really fast so you dont have to wait while using it
