A weaken question on Master GMAT...

A new form of digital memory stores larger amounts of information than current forms by compressing graphic, audio, and video files according to how often they are used, as calculated by an algorithm. Files that are not used often at all are compressed to lower quality levels than those that are used frequently, making the capacity of the new memory system almost three times larger than that of existing memory systems. The company responsible for the new digital memory's creation plans to market it for business and personal use since a consumer poll reveals that in both cases extremely large capacities for storage are always in demand.
Which of the following, if true, casts the most doubt regarding the effectiveness of the company's plan?

A. The compression of all types of digital files can be executed in a sophisticated manner so that the compressed result has not been distorted in a way that will render it undesirable or ineffective for further use.
B. In a recent survey it was noted that the storage and management of digital information in products receives more attention by users looking for solutions for commercial applications than for personal applications.
C. Most products that rely on digital memory to function are priced relative to the capacity of the storage provided by that memory although in some cases products are sold separately to memory components allowing the consumer to then choose from a variety of storage sizes.
D. Almost 90% of the vast number of files stored by businesses are never retrieved and are stored at a high cost, but when a specific file is needed, it may contain information relevant to current issues that may be crucial to the business.
E. Memory systems are likely to be incompatible with a digital product that was developed before their release since the compatibility of digital products is limited and tends, therefore, to be focused on integration with memory systems released at the same time.

The OA is D.

I've chosen E and got some doubt on the OA. I was looking for an choice saying that the plan to market the product is problematic at some other aspects (despite the high demand for huge capacity). I looked at E and thought that compatibility is definitely an issue.

Can anyone shed some light on this? Kindly correct me if I'm wrong. Thanks.
(I've been a silent listener at this forum and this is my 1st post! Thanks everyone for ur time )

The reason that E is wrong, while logical, is that the assumption is we are talking about information going forward. You will still be able to save space with new files, which will shortly dwarf past information.

D is correct because you compromise the integrity of the file if you save it at a lower quality. This may not allow you to use the file for business if it is needed down the road.

Hope this helps.
