By Mitchell Smith on January 28, 2013
When I purchased the OWC Mercury EXTREME Pro 6G SSD to replace the stock Apple 256 GB SSD in my 2011 15" MacBook Pro (2.3 GHz i7 with 16 GB of RAM), I expected it to be faster. I figured that the Apple SSD was about 30% faster than the standard MacBook Pro hard drive, so maybe the Mercury would be....50% faster?

After installing it, I can't believe how fast this thing is. My computer is easily twice as fast overall, but it comes at a cost that I hadn''t seen anyone mention: battery life. My MacBook Pro now loses about 1% of battery every 35 seconds, so I'll be lucky to get an hour out of it without plugging in.

I'm usually connected to power wherever I am, so I'd much rather have a faster computer with less time on battery. I just wish I'd known about that prior to purchase.

Late 2011 MacBook Pro 2.4GHz Quad-Core Intel i7, 16GB RAM: Pairing an OWC 480GB 6G Mercury Extreme Pro SSD (Main Drive Bay) with original 750GB 7200rpm HDD (Optical Drive Bay) for OWC's DIY Fusion Drive Upgrade

• Existing Peripherals

o 4TB LaCie Thunderbolt Storage (purchased as a factory-refurbished unit, now set to RAID 0 striped array across 2 separate 2TB 5400rpm HDDs)
o 27” Thunderbolt Display (main)
o 2TB Time Capsule (Time Machine back-ups and Airport WiFi)
o AppleTV
 iPad Retina Mini (great resource for following DIY videos or using Google mid-project)
 iPhone 4S (great resource for calling someone who knows what they’re doing)

I researched this upgrade for a year and a half. The box from OWC arrived yesterday morning via FedEx. I opened the box when I got home from work about 6pm. I am a complete hardware novice. The most complex thing I have ever done to my system was to replace the RAM. I'm not claiming this upgrade was effortless, or that it took 45 minutes like tech-savvy teens claim online, but it did take less than 3 hours to completely configure both drives and then put my new OWC-supplied tools away in the closet. By 9pm I feeling pretty self-satisfied, and thinking I ought to get ready for bed.

SSD speed is more amazing in person than watching any side-by-side comparison available online. Complete start-up now takes ~20 seconds post-upgrade, as opposed to 2 minutes+ pre-upgrade. App performance (photo editing especially) is vastly improved. In life, nothing good ever comes cheap, and this investment was worth every cent. I’d like to keep my system for as long as possible, and decided I’d rather invest ~$400-$500 to future-proof now than spend $3000+ to buy a newer Mac sooner, rather than later.

Breathing new life to an Old Mac or PC!

i try to stay unbiased with apple products to the best of my ability. I think what i stumbled upon on this guide deserves a shot even by WinTel users as well.

The situation:
Old iMac 24'' 2008
Internal 5.25 drives had died twice
Recovered system via SuperDuper backups
Died again recently
This time did not want to extend 2 days to install a new hard drive

The Opted solution: external SSD Drive
which essentially replaces the need to boot from the iMac 24 native internal drives which are just going to die faster!
(mind you that this drive here is an internal one what i have is not listed on amazon. The one i have is the OWC On-The-Go(tm) Pro
120GB SSD Triple Interface Storage Solution -- [....] )

Results after booting from the external drive:
i did a a simple boot test (no sophisticated measuring tools or anything )
Simple STOPWATCH start and finish :

internal drive boot up time: 1m20sec.
External SSD Via FW800: 45 seconds! (since this was an older iMac i really did not want to get inside it to replace the 5.25 to SSD)

Conclusion:
SSD Drives are fast! sorry i mean BLAZING fast! but you must decide on the uses for it. i for one can declare to anyone
having an OLD PC OR MAC to opt for an SSD rather a newer machine.
I typically use Office, Flash, Mail, Dropbox, Safari, OmniFocus, and OmniProject are the main application i am running in any one go.

The loading and switching and reloading OR file movement is almost as good as "white bread!"
As a result of this little experiment i ended up upgrading my 2 other home laptops to SSD as well.

Had a colleague not pushed me, I'd have been too freaked out by all the old reviews about SSDs, but this is damn near miraculous! I have a fairly souped up tower, but swapping my boot drive from an old Maxtor 7,200rpm to this SSD? It's like I have a new machine! Adobe CS apps start in less than 10 seconds, Mail starts instantly and is much more responsive. It's a marvel!

Verified Purchase
The company is willing to replace it. It does have a 5 year warranty. But, it crashed without reason - and it's going to cost me nearly four times the amount of the hard drive itself to recover the data now stuck on this device. OWC isn't held liable, and I know it's on me for not backing up with paranoid frequency.

I'll be purchasing from Samsung in the future - this has been a horrific experience. My business has suffered as a result! If you're paying premium for premium hardware, the company should help you when their product crashes without reason.
