Western Digital’s SMR disks aren’t great—but they’re not garbage

Ars Technica - June 5, 2020 - 10:40pm

Western Digital has been receiving a storm of bad press—and even lawsuits—concerning their attempt to sneak SMR disk technology into their "Red" line of NAS disks. To get a better handle on the situation, Ars purchased a Western Digital 4TB Red EFAX model SMR drive and put it to the test ourselves.

Although Western Digital's 4TB SMR disk performed adequately in Servethehome's light duty tests, it performed miserably when they used it to replace a disk in a degraded four-disk RAIDz1 vdev. (credit: ServeTheHome)

Recently, the well-known tech enthusiast site Servethehome tested one of the SMR-based 4TB Red disks with ZFS and found it sorely lacking. The disk performed adequately—if underwhelmingly—in generic performance tests. But when Servethehome used it to replace a disk in a degraded RAIDz1 vdev, it required more than nine days to complete the operation—when all competing NAS drives performed the same task in around sixteen hours.

This has rightfully raised questions as to what Western Digital was thinking when they tried to use SMR technology in NAS drives at all, let alone trying to sneak it into the market. Had Western Digital even tested the disks at all? But as valuable as Servethehome's ZFS tests were, they ignored the most common use case of this class of drive—consumer and small business NAS devices, such as Synology's DS1819+ or Netgear's ReadyNAS RN628X00. Those all use Linux kernel RAID (mdraid) to manage their arrays.

Americans are drinking bleach and dunking food in it to prevent COVID-19

Bleach (credit: Adina Firestone)

Americans are doing more housecleaning and disinfecting amid the COVID-19 pandemic and many are turning to wild and dangerous tactics—like drinking and gargling bleach solutions.

Back in April, the agency noted an unusual spike in poison control center calls over harmful exposures to household cleaning products, such as bleach. The timing linked it to the spread of the pandemic coronavirus, SARS-CoV-2 (not statements by President Trump). But to get a clearer idea of what was behind the rise, CDC researchers set up an online survey of household cleaning and disinfection knowledge and practices.

In all, they surveyed 502 US adults and used statistical weighting to make it representative of the country’s population. The findings—published Friday in the CDC's Morbidity and Mortality Weekly Report—are stunning.
