KINGWIN KF-4001-BK SATA Internal Hot Swap Rack 4 Bays w/ Fan

3 out of 5 eggs Fully functional, but no hot plugging 09/13/2015

This review is from: KINGWIN KF-4001-BK SATA Internal Hot Swap Rack 4 Bays w/ Fan

Pros: Well-constructed, 4-in-3 unit that removes the need for drive trays. Uses a spring-loaded mechanism to eject/engage the drives. The bays are kept well-ventilated by a large fan on the rear of the unit, which generates something like ~40-50dB of sound.

Cons: Be aware: a true HotPlug setup requires 15-pin SATA power connectors. This unit uses a single pair of 4-pin Molex connectors, which won't provide your OS the necessary trigger via AHCI to hotplug any drives.

Other Thoughts: The unit really does seem well-constructed, with lots of thought into usability. The dilemma for NAS users, of course, is that the bays aren't hot swappable, i.e. readily introduced to the OS by AHCI. There are several discussions for limitation of the Molex power connector, if you're willing to search for it. The key is to make sure to get the 15-pin SATA power connector for each drive.

It's also important to enable AHCI in your CMOS/UEFI, both at the controller and port level.

OEM Production 2550L2D-MxPC Intel NM10 2 x 204Pin SO-DIMM Intel GMA 3650 Black Mini / Booksize Barebone System

Pros: 1. Cost - For $129, I secured a SFF pc capable of pushing 650Mbps through pfSense (SPI, no Squid/Snort/IPSec/OpenVPN).
2. Small form factor - Very small footprint compared to photos.
3. Four thread CPU - Atom D2550 has two CPU cores with hyperthreading to provide surprisingly robust performance (at least for pfSense).
4. Optional RS-232 - If I want to install the appropriate header, I can add a true serial port later, to eliminate the need for any KVM connections.

Cons: 1. PC Height - The unit is rather tall for a small form factor (compared to PC Engines APU1D or similar). Given that this cost half of the alternative, I'll pocket the difference and enjoy the increased capacity (APU1D @ 400Mbps max tput).
2. Barebones - I would have preferred to find a model that included memory and storage, but even then the costs were far below the alternatives.

Other Thoughts: The performance of the system is certainly surprising, though a thorough search of forums confirmed my expectations before I purchased it.

The more surprising aspect of the unit was the build quality. I must say that the system was fully prepared from the moment I opened the case and installed memory/storage. One USB boot and 10 minutes later, I had a fully functional pfSense firewall capable of 650Mbps and loads of features that don't require me to purchase licensing (aka. Cisco, Juniper, Fortigate, etc.) to enable them.

Pros: 1. Hardware RAID built-in
2. Multiple RAID modes, including 5 & 10
3. Support of 6Gbps SATA
4. Excellent price compared to "Enclosure + HW RAID" solutions.
5. Simple controls for setup and operation
6. Wide number of connectivity options

Cons: 1. Power connector on the side, not back
2. Simple controls = Less functionality for some
3. Excellent price = Extensive use of plastic
4. During heavy file copy operations, I have noted some high pitched beeps from time to time.
5. Included paper manual and PDF manual from website offer limit useful, let alone relavent, information (use the CD instead).

Other Thoughts: First, let me say that I had many doubts about this unit and whether it would match the requirements for a home media/file server that I was building. Without a doubt, the unit has met all of my expectations and even exceeded them a bit (let's just say that the manuals in the box and website isn't nearly as good as the one on the included CD).

Second, anyone using a MAC needs to download the MAC-specific firmware upgrade to resolve the issues noted previously.

Third, the unit wasn't ready to use from the get-go when connected to a server as the only storage option. I had to connect it to an existing workstation to initialize the drives and build the RAID5 array before it was usable with my server.

Fourth, despite the claims of some reviewers about no JBOD and a default to RAID0 (and the manual states RAID5 default), all of my drives appeared as JBOD when first attached, so YMMV.

Finally, know the tool you intend to use for a job. This unit has limitations, so it's not a one-size-fits-all RAID enclosure. However, it's an excellent and inexpensive replacement for pseudo-RAID solutions on motherboards and an good-enough alternative to much more expensive RAID cards (I replaced a much more expensive 3ware 9650SE-4LPML). Unless you need RAID 6/50/60, etc, this unit is a very, very good value.
