The SanDisk Excessive Professional is likely one of the quickest exterior (transportable) SSDs out there available on the market. And whereas that is likely one of the the reason why individuals wish to buy it, and likewise as a result of SanDisk drives and different storage options have a fame for being dependable, the identical shouldn’t be the case with this one.
A fast Google search associated to SanDisk Excessive Professional failures or fails throws up a number of posts, experiences and threads associated to the failure of this explicit mannequin. Whereas loads of individuals have been anticipating to obtain a firmware replace that fixes this downside as soon as and for all, a brand new report means that the issue might be associated to the {hardware} itself and is a consequence of a design flaw and a producing defect.
Markus Häfele, a Managing Director of Attingo Knowledge Rescue, a knowledge restoration agency, alleges the issue is a results of improper contacts attributable to bubble-creation within the solders which consequently results in breaking of the solders that help within the coupling of the elements with the PCB. And the element sizes too usually are not acceptable as per the format of PCB.
Häfele mentioned in an announcement to FutureZone:
We’ve got no less than one particular person each week who brings an exterior SanDisk exhausting drive to us as a result of it now not works
There are a noticeable variety of errors.
It”s positively a {hardware} downside. It’s a design and development weak point . The complete soldering means of the SSD is an issue,
The soldering materials used, i.e. the solder, creates bubbles and due to this fact breaks extra simply.
As well as, the elements used are far too massive for the format meant on the board,
Because of this, the elements are somewhat larger than the board and the contact with the meant pads is weaker. All it takes is somewhat one thing for solder joints to abruptly break.

WD, nevertheless, says there is no such thing as a such {hardware} challenge at play that it’s conscious of. The corporate supplied the next assertion to PetaPixel:
We’re reviewing latest statements which have been made about {hardware} elements in our SanDisk Excessive and SanDisk Excessive Professional transportable SSDs.
We wish to guarantee our valued prospects, that we take the standard of our merchandise very critically and we make use of rigorous testing procedures for our transportable SSD merchandise:
We conduct an intensive DFM (design for manufacturing) course of to make sure product high quality
We observe industry-standard IPC pointers for PCB meeting and design
We use solder paste from an industry-leading provider
We conduct rigorous product-level {qualifications} previous to delivery together with thermal, vibration, humidity, shock and extra
The latest statements counsel that {hardware} elements could have been liable for the firmware challenge that impacted sure SanDisk Excessive Professional 1TB, 2TB, and 4TB, SanDisk Excessive 4TB, and WD My Passport SSD 4TB transportable SSDs earlier this 12 months. Whereas we’re working to assemble extra info, presently we don’t imagine {hardware} points performed a job within the product considerations that we efficiently addressed with the firmware replace.
Häfele apparently additionally believes that WD might concentrate on the underlying manufacturing issues although it has not acknowledged it. They observe that sure newer batches of the mannequin have been upgraded with the inclusion of epoxy resins. “It’s affordable to suspect that Western Digital has acknowledged the issue and needs to make the elements extra sturdy. They wish to supply an extra security issue, however these fashions additionally find yourself with us” mentioned Häfele.
