Western Digital confirms speed crippling SN550 SSD flash change

Western Digital has confirmed that it modified the NAND flash reminiscence in one in all its hottest M.2 NVMe SSD fashions, the WD Blue SN550, which crippled writing speeds in accordance with a number of reviews, resulting in a 50% efficiency hit.

The corporate says that, sooner or later, it would additionally introduce a brand new mannequin quantity when making any {hardware} adjustments to its merchandise that affect efficiency.

Western Digital added that, though it did not inform prospects of this transformation, it up to date the product knowledge sheet.

“In June 2021, we changed the NAND within the WD Blue SN550 NVMe SSD and up to date the firmware,” a Western Digital spokesperson advised BleepingComputer.

“On the time, we up to date the product knowledge sheet. For better transparency going ahead, if we make a change to an current inner SSD, we decide to introducing a brand new mannequin quantity at any time when any associated revealed specs are impacted.

“We worth our prospects and are dedicated to offering the absolute best options for his or her knowledge storage wants.”

Writing velocity lower of as much as 50%

The primary to report that Western Digital swapped the high-performance flash reminiscence in its Blue SN550 M.2 NVMe SSDs with a decrease high quality one with out letting its prospects know was the Chinese language tech information website Expreview.

The NAND alternative resulted in total writing speeds decreases of as much as 50%, in accordance with Expreview, a report that Tom’s Hardware later confirmed.

Whereas in regular circumstances, the SSDs with swapped NAND reminiscence are as quick as these with the unique {hardware}, the brand new ones can’t sustain with the writing requests as soon as the SLC cache is exhausted, and their efficiency will tank from 610 MBps to a meager 390Mps.

Although the corporate did not reveal the rationale behind the change, a attainable clarification is the ongoing global semiconductor chip shortage attributable to the COVID-19 pandemic, which unfold to affect nearly 170 industry sectors.

Taiwan Semiconductor Manufacturing (TSMC), the world’s largest contract chip producer, can also be planning to extend costs by as a lot as 20% throughout late 2021 or early 2022, as reported by Wall Street Journal in the present day.
