Western Digital sued over SMR debacle in HDDs
Back in April, there was quite a bit of discussion about WD mot mention that a part of their NAS line of HDDs was not RAID compatible due to storage methodology. They're now getting sued about it.
Users had been experiencing problems adding the latest WD Red NAS drives to RAID arrays, they suspected it is because they are actually shingled magnetic recording drives submarined into the channel. Problems surfaced once adding a new WD Red NAS drive to a RAID array. Although it was sold as a RAID drive, the device “keep getting kicked out of RAID arrays due to errors during resilvering,” was reported.
SMR and NAS are not compatible
Shingled media recording (SMR) disk drives take advantage of disk write tracks being wider than read tracks to partially overlap write tracks and so enable more tracks to be written to a disk platter. This means more data can be stored on a shingled disk than an ordinary drive. However, SMR drives are not intended for random write IO use cases because the write performance is much slower than with a non-SMR drive. Therefore they are not recommended for NAS use cases featuring significant WD now has been sued because such disks have been sold as NAS HDDs. Law firm Hattis Law has started the lawsuit.
The affected HDD (hard disk drive) models are:
- 3.5″ WD Red 2TB, 3TB, 4TB, 6TB
(SKUs: WD20EFAX, WD30EFAX, WD40EFAX, WD60EFAX)
- 3.5″ WD Blue 2TB, 6TB
(SKUs: WD20EZAZ, WD60EZAZ)
- 2.5″ WD Blue 1TB, 2TB
(SKUs: WD10SPZX, WD20SPZX)
- 2.5″ WD Black 1TB
(SKU: WD10SPSX)

Weird. I do not particularly often write data to my NAS. And I do not need it to write fast.

You're missing the point. Whilst SMR drives are fine in a non parity striped array (unRAID), they suffer terribly in one which is (FreeNAS or hardware raid etc). They should be sued. They missold a product that was designed for use as a NAS hard drive, when the underlying technology within it, is ill suited for that task and actually puts your data at risk.

There is large quantity of SATA SSDs that can't read/write nowhere near their specifications.
When I got myself Patriot Burst 1TB, it could not write consistently more than 40MB/s of game files as I was transferring part of game library from NVMe.
Drive simply gave 100% active time to windows and it shown like 900~2500ms response time.
Then that thing had read speed mostly between 80~200MB/s before hitting 100% active time as I wanted to test how it moves (reads) data back to NVMe.
I could not stand it and it had to go.
Who's suing all those SSD manufacturers? I am pretty sure that this particular SSD is at similar level in practical use as HDD in article.

@Fox2232 i think the issue is they where sold for raid purposes and they could not work on a raid array at all getting kicked out of the array etc
I do not know about you if i had a pick up track and the truck was ejecting anything i try to load at it ... I would have been pretty pissed about it :p

I don't think this lawsuite is going to succeed, the drive is for better or worse, a hard drive.
