WD, aside, is labeling branded SSDs to color classes: a color meaning,
accordingly in keeping with a prior tactic, is to provide no info on
build assembly, short of taking it apart for chip nomenclature (colors
corresponding to an Enterprise grade are spec'd, though).

WD also tends to be positioned somewhat high on average sales value,
e.g. to Seagate, at a minimum, for typically 2T HDDs.

2T HDD drives and 1T SSD are nearest to convergence with typical
Seagate 2T HDD at $60US, and an ADATA SU800, (DRAM equipped and
positioned against a better Crucial SSD counterpart), for frequent
reoccurring sales to value of $80US. Mechanical drives are hence
closer to approaching the alternative solid-state reality.

These are, however, Chinese marketing venues, less commonly reflecting
[higher] prices reserved for US sources (mark-ups on Amazon or
NewEgg). There is an decided imposition to factor for buying from a
direct Chinese-sourced vendor, than US sources for known policies and
practices. (Additional constraints from a US president and his agenda
for 25% tariffs imposed on Chinese goods may affect the future.)

A 1T ADATA SSD, however, is close to performance factoring against
better reserves occupied by Samsung EVO or Crucial MX drives -- for at
as much discounted by 50% over Samsung, and at 25% to Crucial --
potentially both in performance and longevity appreciation.

Least to mention, ADATA has established a US corporate presence for
enhancement and a closer marketing representation for warranty
purposes and assurance.

Disclaim: Adata 650 series DRAM-less drives are not a similar value,
and closer to a bulk of mainstream pricing for cheapest, among least
reliable drives the lowest MTBF associations produced.

Sales on up to 4T HDD are neither altogether inconsiderate, if taken
infrequently for when they do occur, to effectively approach halving
values on 2T class Legacy HDDs.
