Summary: I bought two of these and they have really performed extremely well. My one and only issue is not about their performance, however, but a lack of forethought on the part of the manufacturer involving how to mount these into a computer. The screws that came with the SSD were MAYBE 1/8" long.
Summary: Purchased a few of the 128GB SX900 drives, from NCIX and other stores, all have worked flawlessly, couldn't be happier with them. However, today is now the second 256GB SX900 drive that has died inexplicably. Completely dead, BIOS sees nothing in each case. Cables/Ports/Motherboard all checked clean. I'm in Canada, and all RMA's in North America must be shipped to California at the customers expense (don't forget tracking and insurance).
Pros: Great Cost/Performance Ratio
Cons: Limited RMA support, No RAISE, Dead within 6 months of intermittent use
Summary: My drive came with a cracked sata tab, and was preinstalled with the grub bootloader. Clearly someone else's RMA got repackaged without being wiped. I would have been fine with that had it not a cracked tab. Box appeared sealed when it arrived, so either someone managed to peel off the clear box seals without damaging them and returned it to NCIX for resale, or else ADATA repacked an RMA without thorough inspection. Returned for exchange.
Summary: First drive was DOA, luckily I had another computer in house to verify it was dead, but I lost a whole day trying to make it work. Cloning software would not work on this drive, had to do a fresh install. Last 2 ssd I purchased did not have this problem.
Pros: Good price for a 256gb drive.
Cons: First drive was DOA, took a whole day of troubleshooting to confirm it was dead. Included cloning software would not work.
Summary: Picked this yesterday and was able to install it with no problems. The Acronis software worked well but you need to download and activate it before you can use it. It is good enough to clone your old drive and will get you going but it is not a full version. Also, take note that this is the 'desktop' version that is on sale so you won't be getting a case/enclosure for you old hdd to use as an external drive.
Pros: Easy installation, great price.
Cons: Desktop model, no enclosure for your old hdd.
Summary: Note: Since I bought this SSD in-store, NCIX does not allow 1 star ratings (unless you buy online). But my true rating of this SSD is 1 star! The first day I used this SSD, it was amazing. It was incredibly fast. However, after having used this SSD for over a month now, this SSD has been an absolute nightmare! I bought this SSD to upgrade my system, which I built myself about 1-2 years ago.
Pros: Fast, and that's about it.
Cons: Unreliable, BSODs, Lockups, Freezes, Not able to Boot, Corrupted Data, Inaccessible locations on the SSD.
Summary: This is my second SSD, the first is a 128BG crucial which has been perfect for 2 years. I really hope that this isn't going to be a problem which requires an RMA after I just installed a fresh OS, and all of my games and have everything running perfect. Aside from the screeching noise that is.
Pros: So, I love this drive, its super fast, high enough capacity to fit all of my games on, and was super easy to install and load windows 7 x64 on.
Cons: After a few weeks, has begun to make a high pitch squealing sound when it is loading, or processing info. Pretty much whenever the HDD indicator light flashes, I'm getting the squeal which was loud enough to wake me up last night.
