In purchasing a new 15" MBP, What do you think is better ? 128GB Stock Apple SSD for $100 upgrade, Or OWC 120GB for $244.99? Value vs Long term Reliability, etc. (I will be purchasing a 750GB 7200 rpm drive regardless to be used in optibay.) According to the review on anandtech.com: "what you do get is a drive that Apple will support completely (and also official TRIM support, no 3rd party drives have TRIM support under OS X). In the past Apple has had serious compatibility issues with 3rd party SSDs, so there is some merit to the BTO SSD option." "...At $100 for a 128GB drive you really can't beat the upgrade price" Setting aside for a moment the known speed advantage of the OWC Mercury Extreme - Lets compare the two 1. Price: The Apple upgrade at less than half the price of a similar sized drive has the OWC drive beat. 2. Reliability: Long term reliability is unknown for the OWC drive, however they seem to have a good track record so far. Reliability of the Apple SSD drive, according to reviews, may be more reliable due to increased testing done to the brand(s) they use. 3. Trim support: Current MacBook Pros only support Trim for Apple sold SSD's - is it not known if Lion will have Trim support for 3ed party drives, nor how well they will play with Lion in general. 4. Coming back to speed - Certainly the OWC drive is faster, but is it worth more than Double the price?? My current viewpoint is to go with the $100 Apple SSD and later in six months to a year, after Lion has come out with (potential) expanded Trim support for 3ed party drives, and after the prices have come down on SSDs and reliability of the new SSD's is validated to then get one of the new and fast 3ed party drives. With a 750GB optibay I don't need a 256GB SSD and the price is too high for me anyway for that size at this point, so am only looking at drives under $250. Regardless, I think it's worth $100 for a drive that is certain to be reliable, and then only shift to a more expensive drive after it has a longer track record of reliability with Trim support and no slow down over time. What do u think.
