SSDs plugged in slots S1 and S2 have better IOPS Performances as the plugged in slots S3 and S4

If you are checking the SSD performances and you realized that the IOPS read test in Slots S1 and S2 is multiple times better that the S3 and S4

Unfortunately this is caused by Hardware limitation, SSD 1 and SSD 2 share ASM1062 (PCIe Gen2 x 2) bandwidth, but not the SSD3 and SSD4, This produces that the IOPS performances are a little bit lower in the S3 and S4.
