Biwin Black Opal X570 PRO 2TB Review

We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads.

Random Reads


In the random read tests, all four of the tested threads displayed smooth increases in performance as the queue depth deepened. Test results at QD1 ranged from 20,435 IOPS (83.7MB/s) with a single thread up to 87,941 IOPS (360.2MB/s) using four threads.

Random Writes


In the 4K write tests, the performance rose quickly from QD1 to QD2 (with three and four threads being the fastest) and then a slower rate of rise from QD2 to QD4 before the performance appeared to start levelling off.

KitGuru Games: Predicting the Next Half a Decade of Call of Duty Releases

Benjamin Franklin (1706-1790) famously once said: “The three absolutes in life are death, taxes and a new Call of Duty coming out every single year”. Sure enough, the US founding father has yet to be proven wrong, with Activision and a dozen studios having ensured that come the tail-end of any given year, there will be a new COD ready to release. And so, what can we expect from the franchise later this year? What about 2027, 2028 or even 2030? By looking back at the past two decades of Call of Duty games, their trends, progression and regression, I believe I can predict the next 5 years worth of annual COD entries.
