Random disk read / write speed for disk HP 400 GB MO0400JEFPA

[abelono]

Hi all!
We have 10 HP 400 GB SSD MO0400JEFPA (RAID10) disk group on MSA2040 and 6 SAS 10k disk group on msa2050.
Using the crystaldiskmark utility, we compare the rate of random read and write and it turns out that the rate is better on sas disks.
How can this be explained?
Also, anyone has information about the maximum data transfer rate for the HP 400 GB SSD MO0400JEFPA model. For example, no more than 250MB / s

Hi all,

Does anyone know the maximum bandwidth of this model (HP 400 GB SSD MO0400JEFPA)? For example, 200-250 MB/s?

Thanks.

However,

You are comparing SAS 10K Spinning drives with SAS SSD drives installed on two different Models MSA,

This is not right way to do the performance comparisons,  essentially you should compare across same Model system with same model of drives for any performance issues.
