HP ProLiant ML150 Gen9 review
A compact but powerful tower that’s ideal for SMBs and remote offices

Internal design and storage choices
Build-wise, the ML150 Gen9 is a winner as inside the solid, lockable metal chassis is a well-designed interior. All the important bits are easy to get at for upgrades, and the memory and CPU sockets are covered by a sturdy transparent plastic air shroud that's simple to remove.
For the review, HP fitted four 500GB SATA drives for us to play with but you can choose from a big selection of storage configurations although the sheer range can make it confusing. An extra four-drive cold-swap bay can be added and the server's embedded Dynamic Smart Array B140i RAID controller has a spare connector for it.
If you don't mind losing the 5.25-inch bays up above, the B140i also lets you add two more LFF SATA drives for a total of 10. If you want more, you can add HP's H240 PCI-e RAID card which supports 8 hot-swap 12Gbps SAS SFF drives - or go for a P840 card and max out at 16 drives.
For hard disks, you're spoilt for choice as HP offers a huge range of LFF and SFF drives plus SSDs. SATA, Midline-SAS and SAS are available and HP has now certified 6TB and 8TB LFF SAS helium drives for this server.
