Western Digital Modifications Its Reported Drive Speeds to Mirror Actuality

Western Digital has made some adjustments to the way it manufacturers its WD Pink Plus exhausting drive household after taking warmth for its determination to mislabel its exhausting drive speeds earlier this yr. On the time, particular person prospects carried out some slightly intelligent acoustic evaluation to substantiate that the exhausting drives Western Digital claimed had been 5400 RPM drives had been truly 7200 RPM drives.

Western Digital protested that this labeling was advantageous, as a result of “5400 RPM class” isn’t the identical as “5400 RPM”, but it surely ignored the truth that 5400 RPM and 7200 RPM drives usually have completely different energy and thermal necessities, and that merchandise designed explicitly for 5400 RPM merchandise might need hassle with 7200 RPM drives. The concept speaking truthfully about its merchandise is one of the simplest ways to domesticate and preserve shopper belief doesn’t seem to have occurred to anybody, both.

The corporate has now introduced that it’s going to retire sure WD Pink Plus mannequin numbers and launch new ones to switch them. Nothing is altering in regards to the drives themselves; Western Digital is simply being sincere about the truth that these are 7200 RPM drives as a substitute of 5400 RPM drives. stories that the new model numbers are:

eight TByte: WD80EFBX (-68AZZN0) as a substitute of WD80EFAX (-68KNBN0)
10 TByte: WD101EFBX (-68B0AN0) as a substitute of WD101EFAX (-68LDBN0)
12 Tbytes: WD120EFBX (-68B0EN0) as a substitute of WD120EFAX (-68UNTN0)
14 TByte: WD140EFGX (-68B0GN0) as a substitute of WD140EFFX (-68VBXN0)

Heisse stories that WD has additionally up to date its WD Pink Professional product sheet to learn “7200 RPM” as a substitute of “7200 RPM class.”


The precise WD Pink Plus product sheet hasn’t been up to date but, however presumably that’ll occur quickly.

Why Did Western Digital Do This within the First Place?

The large query it’d be good to have an evidence for is why on Earth WD did this in any respect. When Western Digital launched efficiency lessons with its Inexperienced drives, it did in order a means of hiding the truth that they spun at much less than 5400 RPM, to not cleverly indicate that they had a slower spindle pace than they really did.

I can think about a situation through which it simply turned simpler for WD to run each drive at 7200 RPM. Again when the exhausting drive market was crippled by in depth flooding in 2011, one of many anticipated outcomes that got here true was the disappearance of smaller SKUs. When firms changed their broken tools, they phased out smaller and older merchandise that had been cost-effective to supply as long as previous manufacturing unit tools was nonetheless in play. Possibly WD determined to standardize all of its manufacturing on 7200 RPM motors — however why not simply run the identical motor at a slower pace? Alternately, why not simply promote that you simply now ship 7200 RPM drives normal in all product strains as a means of thumbing your nostril on the competitors?

It’s not unusual for a corporation to promote a element variant that compensates for decrease efficiency in a single class with increased efficiency in one other, reminiscent of compensating for slower spindle speeds with bigger caches, or clocking a CPU with a smaller L2 at a better frequency to compensate. However why did Western Digital go to such lengths — to the purpose of programming its exhausting drives to misreport their very own SMART knowledge — to pretend the pace of its exhausting drives? Was it making an attempt to prop up synthetic market segmentation as a result of it believed margins would drop if it offered principally 7200 RPM drives?

The probabilities that buyers had been injured by this misrepresentation are small, however WD has but to elucidate its pondering.

On October 25, Apple will release iOS 15.1 and iPadOS 15.1. What we know so far




Apple released important updates for iOS 15 and iPadOS 15 on Tuesday, to address several issues and a severe security hole affecting the two platforms. Now, according to reports, Apple is working on iOS 15.1 and iPadOS 15.1 builds for iPhone, iPod touch, and iPads.

Also, Twitter user named RobertCFO received confirmation from an Apple Product Security Team member about the final build’s release date. On October 25th, according to a leaked email that was then deleted from Twitter, iOS 15.1 and iPadOS 15.1 will be released, a week after Apple holds its conference.

This follows Apple’s general software upgrade policy, which is to release new updates a week after its events.

SharePlay, which allows you to remotely watch and listen to streaming material with your friends via FaceTime, ProRes video support, as well as Covid-19 vaccination document support in the Wallet app, are all expected features of iOS 15.1.

PSA: Mining Chia on an SSD Will Completely Wreck It in No Time Flat

When SSDs first started transport in shopper merchandise, there have been comprehensible issues about their longevity. Time, steadily enhancing manufacturing methods, and a few low-level OS enhancements have all contributed to solid-state storage’s popularity for sturdiness. With experiences praising SSDs as provisionally extra dependable than arduous drives even beneath heavy utilization, it’s straightforward to see how individuals may not see the brand new Chia cryptocurrency as a serious trigger for concern.

It’s. Chia is first plotted after which farmed, and whereas farming Chia takes little or no in the way in which of processing sources, plotting it should completely hammer an SSD.

It’s been years since we talked about write amplification, but it surely’s a difficulty that impacts all NAND flash storage. NAND is written in 4KB pages and erased in 256KB blocks. If 8KB of information must be changed out of a 256KB block, the drive might want to learn the unique 256KB block, replace it, write the brand new block to a unique location on the drive, after which erase the earlier block.

Write amplification has been an issue for NAND for the reason that starting and a substantial amount of work has gone into addressing these issues, however Chia represents one thing of a worst-case situation. Right here’s an excerpt from a latest Chia blog post:

Producing plot recordsdata is a course of known as plotting, which requires short-term space for storing, compute and reminiscence to create, kind, and compress the information into the ultimate file. This course of takes an estimated 256.6GB of short-term house, very generally saved on SSDs to hurry up the method, and roughly 1.3TiB of writes in the course of the creation.

The ultimate plot created by the method described above is simply 101.3GB. There seems to be an order of magnitude of distinction between the full quantity of drive writes required to create a Chia plot and the storage capability mentioned plot requires when accomplished.

Motherboard producers have gotten in on the motion, with one Chia-compliant board providing 32 SATA backplanes.

Right here’s what this boils right down to: A number of shopper SSDs are actually unhealthy decisions for mining Chia. TLC drives with SLC / MLC caches will not be really useful as a result of they provide poor efficiency. Low-end and midrange shopper drives will not be really useful, as a result of they don’t provide excessive sufficient endurance. It’s important to watch out through which SKUs you buy and enterprise and enterprise drives are extra extremely really useful normally.

Don’t purchase a QLC drive to mine Chia.

Optane would appear to be a near-perfect match for Chia, given its a lot greater endurance, however I can’t discover any data on whether or not individuals have tried deploying it in massive sufficient numbers to have some concept of what efficiency and endurance seem like beneath the 24/7 load Chia plotters are placing on their hardware. Possibly any individual will put a rig collectively utilizing it, as a lot out of curiosity as the rest.

Past that, ExtremeTech recommends customers not try and plot Chia on any SSD they aren’t snug with dropping, and to not purchase an SSD for the aim until you don’t thoughts throwing it away if it dies far more rapidly than anticipated. Chia plotting is a worst-case situation for SSD longevity and it needs to be handled as such.

One notice of fine information: To this point, Chia mining has had a a lot stronger affect on high-capacity arduous drive costs than on SSDs and smaller drives. Hopefully, this continues to be the case.

Microsoft adapts OpenAI’s GPT-Three pure language expertise to mechanically write code



Microsoft CEO Satya Nadella introduces the brand new GPT-Three integration into Energy Apps in a recorded keynote tackle for the corporate’s digital Construct convention.

Microsoft unveiled new tools for automatically generating computer code and formulation on Tuesday morning, in a brand new adaptation of the GPT-Three natural-language expertise extra generally identified for replicating human language.

The aptitude, to be supplied as a part of Microsoft’s Power Platform, is among the fruits of the corporate’s partnership with OpenAI, the San Francisco-based synthetic intelligence firm behind GPT-Three. Microsoft invested $1 billion in OpenAI in 2019.

“The code writes itself,” stated Microsoft CEO Satya Nadella, saying the information in a recorded keynote tackle to open the corporate’s Build developer conference.

The characteristic is named Power Apps Ideas. It’s a part of a broader push by Microsoft and different expertise corporations to make software program growth extra accessible to non-developers, often called low-code or no-code growth.

Microsoft fine-tuned GPT-Three to “leverage the mannequin’s current strengths in pure language enter to offer Energy Apps makers the power to explain logic similar to they’d to a good friend or co-worker, and find yourself with the suitable system for his or her app,” says Ryan Cunningham of the Energy Apps staff in a publish describing the way it works.
