Summary: This drive worked for well over a year in my MacBook Pro 2010, I don't even keep my data on it, only the OS and Apps. But once it failed, it failed hard. Probably for many of the reasons stated in the many many reviews. Disk Utility could not repair it and suggested I "Back up as many files as possible, reformat the disk, and restore your backed up files.". I did that and decided to check the drive for errors and restore all my backed up data 2x to this disk.
Summary: I gave this a try due to price. The reviews for OCZ SSDs and other memory devices are historically poor in comparison to major competitors (Kingston, Samsung, Crucial, etc.). Unfortunately, the trend continues. This drive was VERY fast when it was new. However, it was placed in a laptop that I only use a few days per month for ~12 months. So it saw little use, and the speed did decline steadily with time.
Summary: Pay for the extended warranty from Newegg. You WILL need it.
Cons: This drive failed during the warranty period. Newegg would not replace it (less than 1 year after purchase). After several emails with OCZ they gave me an RMA. What they sent me as a replacement was REFURBISHED Vertex 3...NOT an Agility 3 like I purchased. Do not trust the warranty.
Summary: I work for a university as an computer admin. I bought 20 120GB Agility 3 drives last summer. Sadly I spec'd Samsung 840 drives but due to an ordering issue, they became out of stock and these drives were supplied instead. Knowing nothing of these drives, I looked them up here and saw they got mixed reviews. Since most people liked them, I proceeded to install them in 20 lab computers.
Summary: While it's fast and cheap, I can't recommend using this in a professional capacity - losing a day in the middle of a week while on a project just isn't worth the price difference.
Pros: Very fast, high capacity, cheap price.
Cons: Died suddenly and somewhat spectacularly. I was using it as my main boot drive in a Mac Pro tower, disk utility on multiple computers won't even recognize that it is a drive now, let alone one with useful information on it. Thankfully I back up, and the latest back up was from about 30 minutes before the failure.
Cons: I bought 2 of these in Sept of 2012, updated to the latest firmware, and started using them in different home computers. Every 6-8 weeks, both of the drives experience an unrecoverable failure, and you need to use the OCZ tool to do a "secure wipe" to reset the drive completely. That works, but of course you lose everything and have to restore from backup or start over. But today one of the drives has failed completely and is no longer recognized by the repair tool. I...
