OCZ RD400 (512GB) PCIe MVM2 M.2 SSD

AS SSD

We again turn to AS SSD to assess a drive’s ability at handling incompressible data.

AS_SSD_4KRead

AS_SSD_4K-64KThrdRead

Here, the RD400 largely mimics what we have seen with Iometer. The drive manages to deliver decent random reads but excels at higher threads due to the additional bandwidth from PCIe.

AS_SSD_4KWrite

AS_SSD_4K-64KThrdWrite

Random write is again a strength for the RD400, where the drive manages to deliver 150 MB/s. It reached impressive 720 MB/s at higher threads.

AS_SSD_SequentialRead

The sequential read for the RD400 is equally impressive at close to 2000 MB/s.

AS_SSD_SequentialWrite
Interestingly, the sequential write within AS SSD is a bit lower than what we get from Iometer where we “only” able to get 1000 MB/s. We said “only”, as it is still quite impressive compared to the performance that SATA SSDs can offer. 

Crystal DiskMark

Crystal_DishMark_4k_Read

Crystal_DishMark_4k_Read_QD32

No real surprise with Crystal DiskMark, as the RD400 performs pretty much like what we have seen so far.

Crystal_DishMark_4k_Write

Random write is almost two times faster than the fastest SATA drives.

Crystal_DishMark_4k_Write_QD32

About double the throughput at queue depth of 32.

Crystal_DishMark_Sequential_Read

Crystal_DishMark_Sequential_Write

Both sequential read and write shows about three times more performance boost over the SATA drives.

Crystal_DishMark_512k_Read

Crystal_DishMark_512k_Write

Crystal DiskMark 512K delivers the theoretical read and write speed of 2600 MB/s and 1600 MB/s, respectively.

Anvil Storage Utility

We have decided to add Anvil Storage Utility to our list of benchmark tools. Anvil Storage Utility has the option to simulate typical desktop applications with 46% compression. We ran the test at this configuration as well as 100% compression.

Anvil_SSD_Benchmark_46

46% Compression (Application)
Anvil_SSD_Benchmark_100

100% Compression

There is virtually no difference between the two test configurations. Here we can see the drive manages to deliver excellent result across the board.

Razer Blade 15 Base Edition (2021)

2020 will go down as a horrible year for getting hold of new graphics card. I still know people who ordered the new Nvidia Series 30 graphics card at launch in September 2020 and still have not been able to receive it. One avenue to get a new Series 30-card might be to go the laptop route instead as it is much easier to get hold of those. Nvidia recently released their RTX 3060, RTX 3070 and RTX 3080-GPU’s for laptop and today I am testing the Razer Blade 15 Base Edition that comes with a Intel i7-10750H, a 15” 165 Hz QHD-screen and a RTX 3070.

  1. Technology has gone too far in upgrading. Each upgrade, has lots of good things added. Better to choose the best among the bests.
