Really interesting article, shame i didn’t see it when it came out, right when i bought a 4tb wd red, not to save money but because it was the right capacity for my expected usage (should be many years before it gets even 50% full).

HDD manufacturers or incentivized to make a lot of drives as cheaply as possible. If the manufacturers really wanted to use SMR for the original purpose they’d be making 18TB SMR drives and not use SMR at all for capacities under about 8 TB. While many of our readers in the US may think of these segments as very small or struggling businesses or consumers without exorbitant means, that is a very narrow view of the world. My best performing SSDs use MLC; the next level down are the 3D and TLC models. Summing up the above perspective, we are at a pretty classical case, but one that is not attractive. Thanks. No vendor wanted to disclose the switch to SMR at low capacities because they had spent years educating the market that SMR was for a different segment. When one looks at where Western Digital is selling its previously undisclosed SMR drives, it is in the low-capacity space. In many ways, they have if you look at the mobile markets. As these firms grow, through absorbing competitors, they can use the best technology and standardize on a fewer number of models, thereby driving up volumes. 4s 158K 1.74M 75.9K 694K 4.44K 0 14.3K 1.31M 46.2K 0 That’s the point.

I have checked 75 percent of my WD RED drives so far and they are all CMR drives; their part number does not match what WD says are the WD RED SMR drives. Having looked at what drives use SMR, I suspect WD/Seagate/Toshiba will take advantage of this situation to justify stopping manufacturing of lower-capacity drives because SSDs are gradually taking over those segments and the low-capacity drives can’t compete on price much because there’s a base cost for components like a 3.5″ shell, the controller, the head and motor.

I just want to know why it took you so long to comment on this. Now what can I do with my RAIDS full of SMR drives that I bought as non SMR? Oh, I agree. Despite being a good thing that we now know at least some of the drives with undocumented SMR, I’ve been tracking a Swiss retailer’s prices for HDDs and even just between last week and this week they increased the price on all Ironwolf/Ironwolf Pro drives by about 10 CHF ($10) while the SMR drives stayed at the same price. Fortunately those drives have been relegated to rarely & barely used “cold storage” RAID systems. latency read write read write read write read write scrub trim We have a video version on YouTube if you prefer to listen instead. The oligopoly of hard drive manufacturers, at some point, decided that moving to DMSMR for these lower capacity customers would help support the market and pricing. 15ns 0 0 0 0 0 0 0 0 0 0 268ms 893K 1.19M 869K 1.52M 3.81K 0 51.2K 622K 116K 0 action: Wait for the resilver to complete.
