Be careful: 18TB and 20TB hard drive reliability are getting worse
Be careful! 18TB and 20TB hard drive reliability are getting worse, durability comparable to QLC.
Everyone knows that hard disks are valuable and data is priceless. Whether it is HDD mechanical disks or SSD solid-state disks, users are very worried about data reliability, especially now that large-capacity 18TB and 20TB hard disks are starting to appear on the market, but many people do not notice them.
The data life is declining, and it is almost the same as the SSD of QLC flash memory .
Servethehome has recently paid attention to the data life of Western Digital, Seagate and Toshiba three HDD hard disk manufacturers .
Western Digital recently launched 20TB Red Pro series hard disks, which are products for high-end NAS and enterprise networks.
It stands to reason that the reliability of the Red Pro series hard disks will be very high, but the rated workload data volume of 20TB is only 300TB , and other red disk series with smaller capacities are even only 180TB .
The situation on Seagate’s side is not second. The IronWolf Pro 20TB hard drive for its high-end NAS positioning has only 300TB/ year of data write capacity.
Toshiba is even worse in this regard. The data write capacity of the N300 series is 180TB/ year, it is still For three-year warranty, Seagate and Western Digital have a 5 -year warranty.
These large-capacity HDD hard drives that are positioned in high-end NAS applications have only 180TB to 300TB of data written , which is obviously not good for NAS that require 7×24 work .
You must know that their enterprise-class hard drives are still maintained at 500TB/ year At the level of MTBF , the MTBF life between failures is also 2.5 million hours instead of the current 1 million hours.
STH believes that these ultra-large-capacity HDD hard drives, even if they are positioned so high, are actually declining in data life, closer to the level of consumer-grade QLC flash SSDs .
