Samsung Blames Pandemic for Bait-and-Switching Customers

A couple months in the past, we protected the information that various SSD suppliers including Critical, Western Digital, and Samsung experienced been caught bait-and-switching consumers. Exclusively, the new drives these providers are shipping and delivery do not generally offer you as substantially efficiency as the variations sampled for evaluation.

We heard from Very important and Western Electronic swiftly, but Samsung took a little bit lengthier to get back again to us. The company has sent above a statement on the topic, reprinted down below:

To make certain ongoing creation of the common Samsung 970 EVO As well as, Samsung has made the decision to upgrade the controller and NAND in the 970 EVO Plus and has up-to-date the firmware to the new model “3B2QEXM7”. The adjustments have been dictated by world wide shortages impacting the creation and availability of quite a few factors and gadgets.

We think that by raising the smart TurboWrite buffer and optimizing application, our gadgets will even improved satisfy the developing requirements of buyers and make improvements to the in general person knowledge.

With the launch of the new variation of the 970 EVO Additionally push, Samsung has posted an up to date datasheet on its web-site. In the party of subsequent element updates, the company will continue to keep the overall improve historical past offered on an ongoing basis to be certain clear conversation with clients.

The 970 EVO Additionally has a very similar issue to the Essential P2 and WD SN550, in that effectiveness on the more recent drives also craters when the SSD has fatigued its cache. The efficiency hit on the 970 EVO In addition is ~50 % according to tests operate on the push, when the Important P2 can reduce as a great deal as 75 p.c of its effectiveness.

Drives like the Samsung 970 EVO Moreover really don’t drop to 100MB/s – 300MB/s, but they nevertheless consider a significant hit. (Picture: 潮玩客)

ExtremeTech confirmed that Samsung has in truth updated the datasheet on the 970 EVO As well as, but the up to date model does not take care of our issues. Here’s a connection to variation 2. of the datasheet, by using the Net Archive, and a stay hyperlink to variation 3..

Samsung has made quite a few changes. Edition 2. of the document contained an overall page of efficiency references and marketing and advertising statements (proven below), but this website page is missing from v3..

This page has been completely eradicated.

Samsung has made two changes to the precise push specs. Initially, edition two. of the document referred to the generate supplying the “Samsung Phoenix Controller,” while v3. references the “Samsung in-residence controller.”

The only other adjust the organization has designed issues a footnote. In edition 2. of the doc, footnote four go through:

Sequential and random compose overall performance was calculated with Smart TurboWrite technological know-how getting activated. The sequential produce performances for the part of facts exceeding above Intelligent TurboWrite buffer dimensions are: 400 MB/s for 250GB, 900 MB/s for 500GB, 1700 MB/s for 1TB and 1750 MB/s for 2TB. The random generate performances for the part of knowledge exceeding above Smart TurboWrite buffer dimension (examined with QD 32 Thread four) are: 100,000 IOPS for 250GB, 200,000 IOPS for 500GB, 400,000 IOPS for 1TB and 420,000 IOPS for 2TB. Efficiency may perhaps change relying on SSD’s firmware, technique components & configuration and other aspects.

This has improved. Footnote four now reads:

Sequential and random publish overall performance was measured with Smart TurboWrite technological know-how getting activated. Intelligent TurboWrite operates only in a unique details transfer dimension. General performance might fluctuate based on SSD’s firmware, program hardware & configuration and other aspects. For specific information and facts, please make contact with your regional service heart.

These are the only a few variations in the doc. There are no new design figures or SKUs described and no discussion of the difference in general performance among its many goods.

Samsung’s method of addressing this problem, it would seem, is to blame the pandemic and remove information from its datasheets. In contrast to Essential and WD, it has not pledged to deal with the trouble with consumers who are not happy with the functionality of their drives. The up to date datasheet does not accept that there are a number of 970 EVO In addition drives in-market place with diverse controllers and unique degrees of functionality. Samsung did not give any added facts on which drive versions had been impacted or no matter whether it supposed to use this tactic in other merchandise.

It is hard to consider that Samsung intends to “keep the entire modify heritage obtainable on an ongoing basis” in the upcoming provided the tenor and character of its reaction now. Samsung’s edits to the 970 EVO Plus’s datasheet don’t make clear anything, they take out efficiency claims and sweep the challenge further beneath the rug.

What this means, in mixture, is that there are two unique versions of the 970 EVO Moreover in-marketplace these days and people have significantly less guidance than at any time on which edition they gained.

The pandemic and possibly a winter season storm very last winter may perhaps demonstrate why Samsung was forced to improve parts, but there is no justifiable rationalization for why Samsung and other producers have swapped parts without having updating SKUs, product figures, or even just sampling new variations of old drives for assessment. Samsung has not tackled our fears concerning the 970 EVO As well as and efficiency on this travel can not be assumed to match critiques if those opinions were published in advance of mid-2021.

Intel is the only producer at present acknowledged not to be swapping NAND and/or memory controllers without having notifying the community or the push. Intel has affirmed to ExtremeTech that it does not swap factors with out launching new product SKUs.
