Works

SUPERMICRO MBD-X9SCA-F-O LGA 1155 Intel C204 ATX Intel Xeon E3 Server Motherboard
SUPERMICRO MBD-X9SCA-F-O LGA 1155 Intel C204 ATX Intel Xeon E3 Server Motherboard

Pros: IPMI, ECC ram support, expansion slots. No construction quality problems. Does support ivy bridge cpus out of the box.

Cons: expensive compared to desktop boards, no dvi (see other thoughts)

Overall Review: The ipmi on the board defaults to being on with dhcp config, so you don't actually need to attach a keyboard/monitor to set it up. PCI slots on any board can only be 3.3v or 5v, it's the cards that can be universal. Takes unbuffered ecc ram.

Most Critical Review

not class 10

Transcend 16GB Secure Digital High-Capacity (SDHC) Flash Card Model TS16GSDHC10
Transcend 16GB Secure Digital High-Capacity (SDHC) Flash Card Model TS16GSDHC10

Pros: 16gb (16130244608 byte) storage, no corruption problems yet. 16MB/s read speed.

Cons: This device does not perform at the claimed 10MB/s write speed. Even with bulk, linear transfers, write speed caps at about 2.5-3MB/s, which is slower then my previous older, smaller, lower (class 6) rated card from a different manufacturer.

Overall Review: if only there was some speficatation available for the controller and it's advertised isp interface, I would try to change the host interface to something more flash-friendly. fat chance of that though, so i'll probably be sending this back, it doesn't work well for my needs.

good performance

SanDisk Extreme 16GB USB 3.0 Flash Drive Model SDCZ80-016G-A75
SanDisk Extreme 16GB USB 3.0 Flash Drive Model SDCZ80-016G-A75

Pros: Meets it's advertised performance at 199MB/s read and 60MB/s write, which I consider impressive (not lying, that is). Good random read/write performance for a usb drive, which is very rare: 8MB/s 4k write speed (all other common measurements are faster).

Cons: There is no standard way to reset the drive to factory condition, so performance will likely degrade significantly with use. This is still probably the best drive you can buy value-wise, aside from the same model with larger capacity (higher sequential write speed on that), or a small ata ssd. I looked for such drives before buying this one.

Overall Review: I'm testing a brand new drive, and I won't wipe it just to see if it gets slower, because it might get slower. That's what professional reviewers are for. Sequential io will be slower over usb 2, but random io will still be fast, don't worry if you don't have usb 3.

slow

Pros: it works. good price for the size.

Cons: Very slow random io speed (~7kbytes/sec 4k write). A "good" cheap flash device will do about 1mbyte/sec. Don't use this drive as an boot device or other use that requires frequent disk access.

Overall Review: This multiple order of magnitude decrease in performance seems to be a trend in new sd cards and usb sticks. I can't comment on reliability, as the device is new.

good sd card choice for mobile/os use

SanDisk Mobile Ultra 16GB microSDHC Flash Card Model SDSDQY-016G-A11A
SanDisk Mobile Ultra 16GB microSDHC Flash Card Model SDSDQY-016G-A11A

Pros: This is a fast sd card for general-purpose use. unlike many current cards, it manages to deliver acceptable (for an sd card) random io performance. measured approximately 1MByte/sec 4k random writes.

Cons: This card really is less than 16gb however you measure it. it's rated capacity is 15931539456 bytes (~15.9GB or ~14.84GiB). It's not a big difference in actual use, but it's disturbing to see.

Overall Review: There's a split between cards that will give around the performance of this card and cards that will give about 0.002mbytes/sec, with not much in between. class-10 cards tend to be of the slow random-io type, surprisingly

Acceptable

Pros: Truely works fanless - open air you won't see >~35c. add a fan if your paranoid and it will drop to room temperature. solid capacitors for heavy-use sections of the board (higher MTBF). dual gigabit ethernet. supported by coreboot for geeks or those needing special configuration. lots of (stock) bios options. supports cpu scaling for even lower power usage. boots fast.

Cons: I was not able to get more then ~500mbit using the onboard ethernet. unsure if it's the realtek or system bus/memory/cpu. graphics chipset is underwhelming by modern standards, but it handles accellerated video playback and such nicely.

Overall Review: tested with debian linux and openwrt (bought to use, and using, as a router). used with transcend ide flash module for no critical moving parts, 512mb ram. pwm/temperature settings for all 3 fan ports can be configured from the operating system (bios has settings for the cpu fan) be careful to use the right type (speed) of ram. if you need more then 1gb ram, you might be using the wrong type of board :)
