IOP over this...

[Zedicus]

ive got a ZFS array with 4 s3700 400gb drives (Z1) and it runs my VM environment. web servers, databases, OSX VMs, you name it. it is nearly full so i need to upgrade for size with out loosing IOPS. should i just move up to the 800gb s3700 or s3710 (these are like 8 years old now) or is there something that is actually better with a SATA connector? enterprise pretty much abandoned SATA so i have not come across anything, help?

Newer generations (S4610 for example) have better IOPS and lower latency, but it's not going to be a significant difference. A single NVMe drive is going to best your 4 drive array.

no NVMe ports. 1U server. limited to 4 sata drives. i can not even add a SAS adapter as i have a 10gb NIC in the 1 PCIE slot. really the 4 drive SATA array is enough performance wise, as long as i well spec the SATA drives.
