In our own Sequential read/write tests, Seagate's FireCuda 510 peak performance for both comes at the QD8 mark with reads at 3,398.71MB/s and writes at 3,058.63MB/s, both of which are shy of the official maximum figure for the drive. At deeper queue depths both read and write performance tails off.
128KB Sequential Read Performance v QD Compared
At shallow queue depths the FireCuda keeps up with the other Phison PS5012-E12 controller / Toshiba 3D TLC NAND equipped drives in the read tests, but at a QD of 32, it lags a fair way behind them which is probably due to the way the Seagate have tailored the controller firmware for their needs.
128KB Sequential Write Performance v QD Compared
It's a similar story with the Sequential write performance. At a QD of 1, the performance of the FireCuda 510 is good, good enough in fact to make it into the top 5 in our result chart.
But as the QD deepens the drive loses touch with the likes of the Corsair Force MP510, PNY XLR8 CS3030 and Patriot Viper VPN100, but keeps ahead of the Gigabyte Aorus RGB, all of which use the same controller / NAND combo.
