Ready Nas NV+ V2 RND4000 SSD drives

And how effective that additional IOPS is in achieving additional throughput in file transfer across the network. We are not talking about internal speed, but whether the additional speed can be seen in additional speed across the network. Considering that the green drives achieving 50-60 IOPS seem to fully saturate the gigabit network, then what good is the additional internal speed?

The IOPS test for green drives is doing 4 Kbyte transfers. So the total throughput for that test is < 250 KB/sec (4K * 60 = 240 KByte), which is of course much less than gigabit ethernet can carry.

Anyway, the main point I am making is that while an x86 or ARM NAS can saturate the gigabit network when transferring large files, the performance falls off very quickly if you are transferring small files or making changes to a database on the NAS. For those usages, the NAS is not limited by the network, it is limited by the disk speed. SSD drives were originally developed to overcome that bottleneck for mainframes (and later on servers).
