I am an IT consultant and have purchased and used quite a few Intel SSDs, not just the 320 Series extensively, but the prior generations like the fantastically reliable X-25M series. I just love these SSDs. They transform ANY computer into a "new" one by decreasing the boot times of an OS and load times of small and major apps so dramatically. Throw one of these in a 5 year old laptop and you've got a machine that will outperform the newest off-the-shelf laptops with spindle-based hard disk drives. I particularly choose Intel 320 series for:
* Reliability, which is legendary. I've used the cheaper OCZ products before, but once one of them literally bricked on me just a couple days after setting up a new PC, I don't even bother to price-compare other brands against Intel SSDs. I have been using Intel SSDs for about 2 years now and have never ever had a single issue with any one of them. I would say I have purchased at least 100 Intel SSDs.
* Price. There is a major hard drive shortage going on right now which has raised the prices of hard drives considerably. Granted, while the GB to GB, apples to apples comparison is still not in SSD favor, you just cannot beat the performance benefits of an SSD vs. any HDD. I only use hard drives for storage. OS and Apps go on an Intel SSD, period.
* Software. The Intel SSD Toolbox is absolutely awesome. It will tell you if there is a firmware update available, easily allow you to upgrade the SSD firmware, and will actually show an estimated life remaining. All flash memory have a finite number of write cycles which eventually WILL deplete, so it's nice to FINALLY have the technology where we can replace something up to, and right before, it fails. I don't believe other SSD brands even offer this kind of a software utility of this caliber.
For those of you who are reading reviews that claim their Intel SSDs failed after so-and-so number of days, weeks, months, whatever, please take note that the reviewer themselves probably most likely did not take the necessary precautions in preventing *static electricity* from damaging these sensitive flash devices! Additionally, even though they do not generate much heat at all, if you put them in a hot environment, it will shorten the lifespan of these sensitive drives dramatically. Exercise proper care!
For those of you who are trying to compare Intel SSDs with any other brand out there, stop looking and just buy an Intel and be done with it. It's worth every single penny and it will enhance your computing life so much, while giving you the reliability you deserve.
