This review is from: SANS DIGITAL HA-DAT-4ESPCIE PCI-Express x8 SATA II (3.0Gb/s) Controller Card
Pros: - Can't tell you how much I love this card.
- 4 ports that can port multiply into a total of 20 drives!
- Very decent throughput, around 120 MBps per port, probably limited by my drives
- Has a fan, the blades look very dinky so not sure how much it can possibly do ti cool it, but anything that has a fan must be more powerful, right? ...Right?
- Picked up the JBOD disks from my RocketRaid 622 card with Gentoo, it took a couple reboots but after I entered the BIOS of the card, exited, then rebooted it found them and my system immediately mounted them after booted
- PCIE x8, so it can handle full throughput on each of its ports
Cons: Found none!
Other Thoughts: I got a 8-bay Sans Digital eSATA enclosure, it came with a rocket raid 622 which had terrible reviews, so I bought a SiL 3132 card, but it apparently wasn't compatible with my PCIe 2.0 slot and I wasn't aware of it at the time. I thought I had a faulty card, so I bought a second one from a different manufacturer, same thing. Just wouldn't show up in my lspci -k.
Unfortunately, my enclosure has 2 eSATA slots that are port multiplied into 4 drives each, so this greatly limited my selection in cards I could use with it, and I never found any that could do exactly two port multiplied eSATA ports at the same time for a reasonable price, I knew there was cards that can do more ports (like this one) but they're more expensive and I thought I'd take my chances.
I put up with the terrible rr622 card for a while, but it kept dropping my drives and failing to write data for any extended period of time (I.e. more than 5 seconds). I eventually decided to just go with this card, and it is such a relief to have a working eSATA port multiplier card.
This review is from: Watts Up? Pro Electricty Meter with RealTime Logging Software
Pros: Can track a bunch of useful data: Amperage, Amperage Maximum, Amperage Minimum, Cost, Cost/Month, Duty Cycle, Kilo Watt-Hours/Month, Line Frequency (Hz), Power Cycle, Power Factor, Voltage, Voltage Maximum, Voltage Minimum, Volt-Amps, Watt-Hours, Wattage, Wattage Maximum, Wattage Minimum
Can record a roughly week of data if logging every minute, but this depends on how many types of data you want to save
Has a LCD display and a button to cycle between data types to view the information in realtime
Has a nice tool that can save data from the device, as well as change its settings or simply view the data from it
Has a API that can be used via a virtual serial port, this can even provide
Cons: The included USB cable is rather short
I once somehow tripped the power to the computer plugged into the Watts Up Pro by moving the unit, not sure if it has a loose connection somewhere or what
Only 1500 watts supported, so I guess you can't measure all power tools =). Probably don't want to go past 1500 watts anyways, or you're approaching your breaker's limit.
Other Thoughts: I made a plugin to display realtime data from the Watts Up Pro to Rainmeter on your desktop, you can download it off the forum post at Rainmeter's siteREAD FULL REVIEW
Pros: Seems like a decent card overall, but description is lacking some important information.
Cons: Says it support FIS-based port multiplication, which it does, but only on one esata port at any given time. This means in total, you cannot have two ports used for port multiplication. In total, you can have one port multiplied port (giving you up to 4 devices) and 3 single ports, yielding 7 devices in total.
I only give it three eggs because it didn't put this in the description.
Other Thoughts: I haven't purchased this device, but I did my research when deciding if I should. The SIIG website clearly states you cannot use two esata ports at the same time with both using port multiplication.READ FULL REVIEW
