Summary: high price used to stop me buying intel ssd. Now they are pretty much same as other competitor. this 330 240gb was an amazing deal for me, and mine is retail, comes with mounting kit and nice 'speed demon' sticker. it's very reliable, I run trim regularly, and diag time by time. 4 month, so far so good. 330 is slower than 520, also slower than crucial M4. But the gap only reflects on benchmark score. I own 330, 520, and m4, I can't feel much diff for common daily use.
Summary: Bought this on a Black Friday deal to install in my Acer Laptop. Cables and 3.5" adapter included for desktop. Luckily, I had SATA to USB connection kit and hooked it up to my laptop. Downloaded the Intel Data Migration Tool and it copied over my HDD to the SSD. After that, I just had to take out the HDD and install the SSD and things have worked perfectly. Crystal Disk Mark was 250 MB/s read and 150 MB/s write, which is likely limited by my laptop's SATA 2 interface.
Pros: Easy to install. Included Intel Data Migration program was excellent.
Summary: I bought this elsewhere because it was on special but a couple of days later NCIX had it on for the same price. Everything went fine installing a fresh windows and I like their toolkit. Testing on CrystalDisk indicates it seems to be about the same speed as my previous 120GB OCZ Solid. I thought the version I bought was retail but it turned out it was the same reseller version that NCIX has.
