Seagate is one of the big names when it comes to the storage industry with products ranging from HDDs and SSDs (SATA & NVMe). The company has been steadily updating its IronWolf line of SSDs over several generations. The IronWolf series itself is aimed at consumers but also serves its good purposes within the prosumer segment. Last month, Seagate launched its brand new IronWolf 525 series NVMe SSDs which are Gen 4 compliant and also marketed towards NAS systems.
According to Seagate themselves, the IronWolf 525 NVMe series will offer all the key additions such as IronWolf Health Management System & Rescue Data Recovery services to reduce the probability of data loss on NAS systems. The drivers also going to be priced accordingly in the entry-level PCIe Gen 4 NVMe segment

Today, I will be testing the IronWolf 525 500 GB from Seagate which comes at a cost of just $149.99 US.
Seagate IronWolf 525 500 GB Gen 4 NVMe SSD
Seagate states that its IronWolf 525 series is an ideal choice for creative pros and businesses with demanding performance needs. It is Gen 4 compliant and backward compatible with PCIe Gen 3.
The SSDs are based on the NVMe SSD form factor and features a 96-layer Kioxia BiCS 3D TLC NAND flash which offers larger capacities, better performance, and slightly lower power input. Seagate is using the Phison E16 (PS5016-E16-32) SSD controller to power its IronWolf 525 series SSDs which is a Gen 4 compliant controller.
