Pros: It really is quiet, even with the ECO mode turned off. Seems like a very good unit overall, I like it. I had a tech question so I called EVGA tech support. It was the best tech support I've gotten from anybody in a very long time.

Cons: No cons really, but for minor suggestions: The 24 pin MB connector has a pretty high insertion force into the MB, and the SATA connectors at the drive end are a little harder to insert than some others I've used. I don't like to use a high insertion force on motherboards. It might be better if the MB plug was in 2-pieces instead of all in one. The printed manual is very vague about the use of the "self tester". In general the manual is not great. I downloaded the online version of the manual, which is a pdf. Usually you can search a pdf for any word you want to find. But in this case there were large parts of the pdf that were non-searchable text, like pictures instead of text. One of my pet peeves is non-searchable text LOL!

Overall Review: At first I thought my unit was DOA. It would come on for about a second, then go back off. I could recycle it and do that again by turning the main switch off and back on. That was with it installed in my computer and everything hooked up. That's when I called EVGA tech support. What I found out from Garrett at tech support was this: The pin-out of their connectors at the power supply end is not necessarily the same as every other manufacturer, even though the plug itself physically fits. I was re-using the SATA power cables that had come with a Sparkle Magna 900 a few years ago. Turns out that was the problem. I put the EVGA cables in there, to all the SATA devices, and that fixed it. Different pinout, wow. I would think the ATX standard would make that a no-no, but apparently not! Anyway, good ending, everything is fine with it now, and nothing was damaged by having the wrong pinout cables in there at first. When the wrong cables were on it, the PS would sense a fault and turn itself off, after about 1 second.

Pros: The basic power unit and fan seem like good solid hardware. I bought this CX600 in May of 2011 and am still using it.

Cons: The two cables to the hard drives are poor, as in, 4 of the 6 connectors at the HD end don't work anymore. Each cable has 3 connectors. The connector at the very end of the cable still works. The other connectors that are part-way along the cable gradually quit working over time. Now those 4 connectors are all non-working. Also the wires that are in these 2 bundles have stiff insulation, which is asking for trouble every time you have to bend the wire bundle to make it fit somewhere. Wires of this small gage should be very flexible.

Overall Review: No excuse for the crummy reliability of the connectors on the cables to the hard drives. These connectors all worked when new, but they failed one by one over time. Every time one would quit working it would scare the heck out of me because first thing that happens is your computer quits working - with a hard drive error. So right away you're thinking, oh no, gotta start all over again with a new install on a new hard drive. But not so, it's just these crummy cables. This type of thing should not be in even the cheapest product level. I do have a large case with 6 hard drive bays. Right now I'm only using 2 drives so I'm ok with the 2 connectors that still work!

Pros: It does have a longer frame that goes deeper into the chassis. This gives you more mounting options than some of the other brands.

Cons: Headphone audio port did not feel right on mine. Had to always push quite hard to get the headphone plug into it. So I quit using this one and bought a different brand. Also the 2 audio ports are not labeled as to which is mic and which is headphone, except for very faint pink and green color coding that I didn't even see until it had been in use for a while. Most of the other brands are labeled with symbols at least. The USB ports are not labeled with any text. Most brands will label those with text that says USB 3.0 or whatever.

Overall Review: Bought this in December 2015.

Pros: Works perfectly and was easy to install.

Cons: Well, this is not the card's fault, but since this plugs into a pcie slot, your hard drive status LED on your case will not pick up activity of the drives that are attached to this card.

Overall Review: This card is backward compatible all the way back to PCIe version 1, which is what my mobo has. I was actually able to get an answer back from SIIG tech support by email, in just a day or 2. Unusual! It is designed to use one of those short 1-lane PCIe slots that you probably have lying around doing nothing on your mobo, but you can also put it in any PCIe slot with any number of lanes - 4,8, 16, whatever. Don't get scared when you start reading the instructions. If you read carefully, you will see that the first batch of instructions is only for something I would never do, not quite sure what it was. But if all you want to do is add this card to an already working system, so you can use additional drives (which is what I'm doing) go to the next batch of instructions, and that is easy just like you would expect. I am using both ports on this card. The drives I have plugged into it are SATA III disk drives.

Pros: Speed is way faster than any disk drive I have ever had. Reliability seems perfect so far. There are no special tricks required other than the little adapter plate to fit a 3.5" bracket space, which is included. No special formatting, no problems recognizing the drive, it just works. I will be buying another one in a few days for a Win7 computer.

Cons: None with the drive itself. I do have a minor problem fitting it to the 3.5" drive drawers in my Coolermaster Cosmos 1000 case, which has unusual drive drawers that mount the drive using the holes on the bottom of the drive rather on the side of the drive. I wind up using the included adapter bracket and packing it into place in the drive drawer with 1-sided sticky thick felt pads, which works ok. The pads don't touch the drive, they are between the adapter bracket and the drawer in the case.

Overall Review: I have been using this M5Pro Extreme 128 GB for 8 months now, in my WinXP system. Previously I was using a Corsair Neutron GTX 120 GB. The Neutron was also fast, at least as fast as the Plextor, but the Neutron failed after about 9 months of use in the same computer. Speedwise I would call the Plextor M5P and Corsair Neutron GTX pretty similar. Reliability, I am hoping this Plextor will last for many years, because I am tired of short-lived boot drives. I have gone through 3 or 4 WD Blue disk drives in the last 3 years and I am done with them. When you comb through the manufacturer's claims about reliability on the Plextor web site, you find more information about reliability than with the other makers of SSDs. I am hoping this is the real deal. The only other drive I know of currently that I think has top notch reliability is the Seagate Constellation ES disk drive family. The Constellations are "enterprise" drives, they are several ounces heavier than a comparable WD enterprise drive, and I think better quality overall. I use a 1 TB Constellation ES for my data drive, and another 1 TB Constellation ES for a backup drive. The 128 GB Plextor SSD is big enough for me to install my OS and all my applications and still have lots of space left over, given the separate drives for data and backup. I don't install games however. If you want a lot of games installed on an SSD, you would probably need a bigger one, or a second SSD just for game installs.

Pros: AV-GP WD10EURX - I probably shouldn't give it a rating yet because I've only been running it for 2 days. But the speed seems good - stopwatch timed transfer of my 520 MB outlook pst file from a WD Blue to this WD AV was 6 seconds, vs 8 seconds for transfer of the same file from 1 WD Blue to another WD Blue.

Cons: Before buying it I spent a lot of time trying to figure out if I should run the Acronis WD Align or not, and pondering the possible troubles of mixing this "Advanced Format" drive with 2 other drives in the same system that are not Advanced Format, in a WinXP system.

Overall Review: I am happy to report that it works fine in my XP system without running WD Align. I decided not to run WD Align. Was on the fence about it until I read this: "WD does not support using any of our Advanced Format Drive alignment utilities on third party USB enclosures". I might use it that way eventually, as an external backup drive. Also annoying in the WD web support (about 5 pages on Advanced Format) was the confusion - does WD Align align the WinXP operating system - or does it align the drive? You can read it different ways in different places. I didn't want it messing with my WinXP system, where this drive is the 3rd drive, where the boot drive and data drive are non-advanced-format. Happily it seems to work just fine without the Align thing. I did have trouble getting my system to see it at first. What I finally had to do was like this. I had never paid any attention before to which sata cable went to which hard drive. When I added this drive, it took me about an hour to figure out I had to connect sata1 to the boot drive, sata2 to the 2nd drive already in use, and sata3 to the new AV drive. Then in the BIOS setup, there is a page where sata 1 through 6 are displayed and you can change their order in the list. I had to order the boot drive 1st, 2nd drive 2nd, the new AV drive 3rd. Then Disk Management finally could see all the drives, and I could initialize the AV drive and format a partition on it. Success. My mobo is a several years old ASUS Nvidia chip drive for AMD cpus, Sata 2, an M2N SLI Deluxe. It just won't die and I'm fine with that, I love it. This drive is my second attempt at spending more money in hopes that I would get a more reliable drive. My first attempt was a failure - Corsair Neutron GTX was scary fast but it only lasted about 9 months! The Neutron was my boot drive. Now I can't even recover data from it!
