This review is from: PQI Nano 32GB USB 3.0 Flash Drive Model 6338-032GR2XXX
Pros: Small and compact
Attractive and glossy look
Fast USB 3.0 class speeds.
Write Protect Switch (for extra security)
Cons: No place on unit to store cap when removed.
Write protect switch is harder to set than it should be.
Case not actually metal but "metallic" (plastic).
Other Thoughts: At the time I purchased this flash drive, it was one of the few USB 3.0 models that also has a write-protect switch. The write-protect switch (which makes the flash drive read-only until set back) prevents the unit from getting infected from a virus or malware. This is an essential feature for anyone who finds it necessary to travel around and transfer data (like a presentation) to various remote or unfamiliar computer systems while being sure nothing can infect the drive and be brought back "home". I would have given the unit 5 eggs if it felt less flimsy and had an easier to access write-protect switch.

Pros: Inexpensive when on sale.
Attractive looking modular power supply with four PCI Express connections.
The included connectors are identical to the connectors of an older Rocketfish 700W power supply I own, giving me more cable management options for use with both PSUs.
The connectors are sleeved in black mesh which helps to hide them and make for a more attractive build.
Cons: DOA -- never worked even once and had a burnt, electrical smell to it.
Quality contol for Rosewill is apparently lacking, resulting in many of their PSUs arriving either DOA or burning out within a few months.
I spent $16 to send this defective unit back to Newegg, negating the advantage of buying the unit on sale.
Other Thoughts: This was my first purchase of a Rosewill PSU. I used the 750W PSU to replace on older working 700W PSU in a system. First time I powered up my system with the new PSU, my system began to reboot continuously, even when the PSU was plugged-in to only a few peripherals. I really wanted to like this power supply, but getting a defective unit makes me worry about the quality control at Rosewill. The customer feedback of higher-end (650W+) Rosewill PSU models shows several with an unusually high percentage of 1-egg ratings (often DOA units). One model has 20% of its ratings = 1 egg, and another model has 25% of it's ratings = 1 egg. Think about it: 25% means that 1 in 4 customers had a problem with it. Not good, especially when the customer has to spend money to ship back a defective product.READ FULL REVIEW
Pros: Assuming a proper cable is purchased, SATA III hard drives can connect at 6 Gbps.
Good compatibility with older motherboards. I used an Asus P5E x38 motherboard.
Using mechanical hard drives, this card outperforms competing cards in RAID 5.
Using a RAID card makes it possible to transport an array to a different machine with data intact, not likely with motherboard RAID.
512 MB cache supercharges smaller file transfers and assists in larger file copies. See other thoughts for benchmarks.
The card's onboard RAID chip performs the processing necessary for RAID, without stealing cycles from the CPU like cheaper cards or software RAID.
Cons: Boot time - With card installed, takes about 30 seconds longer until logon screen appears.
Does NOT come with cables. (Its cheaper to purchase the card and cables separately anyway.)
Requires additional cooling than the built-in heatsink. I used Vantec Spectrum Fan Card (Model SP-FC70-BL) which by default aims the flow of air perfectly at the card's heatsink.
Seems more optimized for mechanical hard drives than SSDs.
Required about 27 hours to initialize 6TB RAID5 array with three 3TB drives.
Other Thoughts: I purchased the card to create a RAID5 array on an older PC using three Seagate 3TB hard drives (STBD3000100). 64 Kb stripe size, used default allocation unit size in Windows.
Plugged the card into the 2nd PCI Express x16 slot.
Any reviewer should mention their motherboard and model(s) of hard drives and whether it all works together or not, as compatibility info is very valuable to know.
I purchased the StarTech SAS8087S450 SAS Cable which saved money over buying the "kit" that includes the card with a cable.
Warning: Western Digital drives are known to drop out of RAID arrays unless they are the WD Enterprise (RE4) series!
Benchmarks using CrystalDiskMark 3.0.1 x64:
4000 MB file size
Sequential Read : 300.667 MB/s
Sequential Write : 297.637 MB/s
50 MB file size
Sequential Read : 1312.676 MB/s
Sequential Write : 1284.467 MB/s
Not a typo! Probably due to 512MB cache on the card.
