Pros: Fantastic support!

Cons: Doesn't play nice with other scanners, but that's a problem with Windows, not the scanner.

Overall Review: To update my previous review. I have since purchased an additional scanner (Canon flatbed), and my Plustek seemed to stop working correctly. After weeks of putzing with it, I finally contacted Plustek support. Within a day, I had a phone call from a live technician who spoke perfect English, and was immediately able to identify my problem, that Windows doesn't like to talk to multiple scanning devices at the same time (have to disable in Device Manager). Followed the technician's instructions and my scanner works like brand new. I was astounded that I get better support on a $300 scanner than on Dell gear, where I spend many thousands of dollars a year on service contracts.

Pros: It's a WD Black. I've had nothing but good luck with them. It's pretty fast, but if you want speed, you should really buy two (or more) and dump them in a RAID0 (with a real RAID controller, skip the onboard garbage).

Cons: It's REALLY loud! Seriously, I haven't had a drive this loud in probably 5 years. This drive is unbelievably loud for a modern hard drive. It sounds like it's trying to chew through the side of the chassis and eat me.

Overall Review: I might already be dead. Eaten by my hard drive. :(

Pros: * Price * 5-bays * Seems to be stable

Cons: * Packaging (product box) fell apart as soon as it was opened. * Packaging and manual have horrible grammar, and spelling. * Firmware update available from website claims to fix an issue in Linux, but instructions state that update should be run in Windows XP...in 2018?! * Performance of the JMicron controller is okay, not outstanding (details below). * Inserting/Removing disks cause a complete reset of the controller. * Device is more noisy when idle than under disk activity.

Overall Review: I figured that I would get what I paid for with this, but I was hoping for a little more. I have been testing this device with 3x 3TB 7.2k disks in a RAID0 configuration. I have tested both software RAID (macOS) and the built-in "hardware" RAID. Using software RAID, write speeds are constant at around 190MB/s, and read speeds are around 210MB/s for sequential access. The built-in RAID peaks higher, but performance drops off after ~30 seconds, to around 70MB/s.. The device resets on drive insert/removal (software RAID, testing insert/remove of disks not in a configured array), causing problems with mounted arrays. The noise produced by the device when there is no disk activity is obnoxious. I have been writing junk data, just so I don't have to listen to it.

Pros: - WAS fast

Cons: - Failed quickly

Overall Review: Purchased to use as a portable linux OS in a secure environment. Worked well, briefly. Device now refuses to allow read-write operations in any OS. Cannot return, due to the nature of the contents.

Pros: Impressively fast, 76MB/s sequential write on FW 800Mbps. Rubber footy-things to keep enclosure planted. Firewire 800 cable included. Kind of matches my MBP. Runs cool with a good drive.

Cons: End caps are plastic. No indication of what 1394B port you need to plug in to get 800Mbps (outboard one). Internal design is a bit clunky.

Overall Review: Bought this to house the original disk drive from my Macbook Pro after an SSD upgrade. I've never used firewire before, but I am very impressed with the throughput, compared to USB2 enclosures I've used in the past. 39MB/s at 400Mbps, 76MB/s at 800Mbps. I initially thought it was garbage due to throughput with an SSD installed, maybe it just doesn't like SSDs? Maybe my testing methodology was flawed.

Pros: 9 drive bays! 2U! Fans Included Low price

Cons: *Front Panel is very flimsy steel (mine came pre-bent) *Power Supply MUST have a rear-mounted fan for proper ventilation. Bottom-mount fans have clearance issues in a 2U chassis *Power supply exhausts out front of case, feeding hot right back into the intake for the rest of the chassis. *Screw placements in the bottom and sides of the chassis are irksome.

Overall Review: I was very excited when I saw this chassis on sale. When I got this chassis out of the box, I immediately noticed that the front of the case was caved in and the top lip all bent up. The shipping box is in good condition, so there would seem to be a quality control issue. The other 5 sides of the chassis are solid, I wonder why they would have used such thin steel here. The PSU mounting is backwards, with the exhaust directed out the front, making this chassis unsuitable for use in a hot/cold-aisle datacenter. I will be returning this chassis, as it is damaged. It's very disappointing to see this from Rosewill, as I have been very happy with most of their other products.
