Our Verdict

The Vulcan Z 4TB uses QLC NAND — four bits per cell — which is the reason it reaches $0.082/GB ($328.99), the lowest price per GB in this entire batch. Sequential reads are 550 MB/s; writes are rated 470 MB/s, but QLC sustained write performance drops when the SLC write cache is exhausted during large sequential writes, making the rated figure optimistic under heavy continuous load. TBW endurance is 800 total, but per TB of capacity that equals 200 TBW/TB — compared to 600 TBW/TB for the TLC-based Vulcan Z 1TB. For read-heavy use cases — game libraries, media archives, file storage — QLC endurance limits are rarely hit and the 4TB capacity at $328.99 is a strong proposition. 917 reviews is a modest sample for a newer large-capacity SKU; confidence is lower than the Vulcan Z 1TB's 7,130. For sustained write workloads or a sole primary OS drive, QLC's endurance ceiling is a real consideration. Right buy for: SATA-compatible desktop systems that need maximum bulk storage capacity for game libraries or media archives at minimum cost — not the right choice as a primary OS drive or for workloads with heavy sustained sequential writes.
