Seagate's FireCuda X Series of NVMe SSDs Leak Ahead of Official Launch
Following Sandisk's new naming scheme for NVMe SSDs, it now looks like Seagate is ready to announce a shift to a new naming for some of its SSDs as well. In a leak that at least in part appears to be thanks to a spec sheet uploaded by Best Buy, Seagate's upcoming FireCuda X series has leaked and the first model in the new series looks to be the X1070. That's a pretty big jump in model numbers, as Seagate's current top of the range FireCuda NVMe SSD is the 530R. Unlike the Barracuda 540, the FireCuda X1070 isn't a PCIe 5.0 drive and it does in fact not even trump the FireCuda 530R in terms of performance, despite the new model name suggesting it would.
The X1070 offers a max sequential read speed of 7200 MB/s, down from 7400 MB/s for the 530R and max sequential write speed of 6000 MB/s for the 1 TB SKU and 6500 MB/s for the 2 and 4 TB SKUs, where the 530R ranges from 6800-7000 MB/s. The random IOPS are also lower at around 900k vs. 1.3 million. The TBW rating is also about half that of the 530R, somewhat depending on the SKU, but Seagate still offers a five year warranty. The only good news is that the power usage is down by around 3-4 W, again depending on SKU, but this suggests we might be looking at a DRAM-less model here. We'll have to wait for the actual launch to find out the pricing, but it looks like the current FireCuda 530R is a better option over the X1070, unless you need an SSD that is more power efficient and hopefully produces less heat.

The 530R is listed at 4769 dkr ( I gave 6995 dkr when it was released - so thats not as bad as back then)

These were, and still are in most respects, some of the fastest Gen 4 drives out there, so I'm extremely happy with them, as are my clients that have them in their rigs that I built for them :D
I would guess that Seagate regrets investing in their hard drives with a small SSD cache instead of getting a NAND fab back in the day...
Hope these still have DRAM tho!!
