Question 1

Is this a 7200 rpm drive or 5400 rpm?

Accepted Answer

All the Easystore drives are 5400 RPM. Model: WDBCKA0080HBK-NESN uses a WD80EMAZ White Lable. Other 8TB model numbers use other drives, some good, some not so good.

Question 2

Whats the max file size this hdd is capable of downloading? I had an old seagate 2tb hdd and it could only download files up to 4 gb.

Accepted Answer

The drive doesn't dictate max file size, the file system does. Your 2TB drive must have been using FAT32 which is limited to a max file size of 4GB. Try using NTFS instead which supports much larger files.

Question 3

Does it come with USB cable and power adapter?

Accepted Answer

Yes it does, but the usb cord and or the power adapter stopped working with in 5 months. Had to replace both the drive to start working again!

Question 4

Why is the capacity of an 8tb actually only 7.45 tb?? according to the device partition manager, not just the drive explorer.

Accepted Answer

Hard drive manufacturers market drives in terms of decimal (base 10) capacity. In decimal notation, one megabyte (MB) is equal to 1,000,000 bytes, one gigabyte (GB) is equal to 1,000,000,000 bytes, and one terabyte (TB) is equal to 1,000,000,000,000 bytes.

Programs such as FDISK, system BIOS, Windows, and older versions of macOS use the binary (base 2) numbering system. In the binary numbering system, one megabyte is equal to 1,048,576 bytes, one gigabyte is equal to 1,073,741,824 bytes, and one terabyte is equal to 1,099,511,627,776 bytes.

Simply put, decimal and binary translates to the same amount of storage capacity. Let's say you wanted to measure the distance from point A to point B. The distance from A to B is 1 kilometer or .621 miles. It is the same distance, but it is reported differently due to the measurement.

Capacity Calculation Formula

Decimal capacity / 1,048,576 = Binary MB capacity 
Decimal capacity / 1,073,741,824 = Binary GB capacity
Decimal capacity / 1,099,511,627,776 = Decimal TB capacity

Example:
A 500 GB hard drive is approximately 500,000,000,000 bytes (500 x 1,000,000,000).

500,000,000,000 / 1,048,576 = 476,837 megabytes (MB) = 465 gigabytes (GB)
