Are 18TB drives reliable?
For example, the confidence interval for the 18TB Seagate drives (model: ST18000NM000J) ranges from 1.5% to 45.8%. This is very wide and one should conclude that the corresponding 12.54% AFR is not a true measure of the failure rate of this drive model. More data is needed.
What is WD hard drive?
Western Digital Corporation (WDC, commonly known as Western Digital or WD) is an American computer hard disk drive manufacturer and data storage company, headquartered in San Jose, California.
How reliable are WD Blue?
The WD Blue WD40EZAZ is a reliable alternative option to an SSD, offering improved performance on desktop PCs for those who want to use a high-capacity HDD. Due to its 3.5-inch form factor, this hard drive is not suitable for laptops.

Formatted Capacity The Western Digital Black Series does come in higher capacities (up to 10TB), so if you are in need of a large quantity of high-performance storage, the Black Series is for you. WD Blue currently tops out at 6TB maximum capacity.
What is CMR vs PMR?
Perpendicular Magnetic Recording (PMR) PMR, also known as conventional magnetic recording (CMR), works by aligning the poles of the magnetic elements, which represent bits of data, perpendicularly to the surface of the disk. Magnetic tracks are written side-by-side, without overlapping.
What is TGMR recording?
TGMR reader is current technology of magnetic recording read sensor which dramatically improves readout amplitude, speed and recording areal density.
Why are SMR drives so slow?
As Blocks & Files notes, SMR disks are meant to store more data on a disk platter than conventional magnetic recording (CMR) disks by partially overlapping write tracks, resulting in much slower write performance than a non-SMR drive.
Are SMR drives OK for backup?
That being said, the SMR technology does make this drive one of the best for $s/TB on the market, just don’t expect amazing performance from it. You definitely get what you pay for, and for it’s intended purpose as a backup drive it works fine.
