The SSD Advantage

Whether you're refreshing an older laptop or trying to maximize the potential of the latest platform, SSDs provide substantial benefits over traditional hard drives.

SSD speed compare
Greater Durability

Solid State Drives feature a non-mechanical design of NAND flash mounted to circuit boards, shock resistant up to 1500g. Hard disk drives consist of various moving parts making them susceptible to shock and damage.

Faster Performance

SSDs have 100 times greater throughput and instantaneous access times for quicker boot-ups, faster file transfers, and overall snappier performance than hard drives. HDDs can only access the data faster the closer it is from the read/ write heads, while all parts of the SSD can be accessed at once.

Less Power Consumption, Silent Operation, and Lightweight

SSDs use significantly less wattage at peak load than hard disk drives--less than 2W versus 6W for an HDD--delivering longer battery life in notebooks, less power strain on system, and a cooler computing environment. With no moving parts, SSDs run virtually silent in your notebook or PC case to eliminate distracting noises during gaming or entertainment. And SSDs won't weigh down your laptop, netbook, or tablet PC when you're on the go.

SSDs run much cooler than hard disk drives...
...and much quieter, too.

I purchased the Vertex 3 specifically for gaming so this will the focus of my review. I've owned all three generations of Vertex drives and I'm most pleased with this drive. That pleasure comes from the capacity and speed of the Vertex 3.

The Vertex 3 drive itself is a 2.5" form factor and comes with a 3.5" adapter this time around. Great for those desktop installs, however you will still need to purchase a SATA cable to connect it. To get the most out of this drive, you'll need a SATA III (6GB) port since the blazzing speed of this drive will max out a SATA II connection.

The drive currently resides in my sandy bridge desktop system as a secondary storage location for all my steam games and Starcraft 2. Along side a Vertex 2 60 gig that is the primary OS disk, the formated capacity of 223GB provides plenty of space for most of the titles that I actively play. It was a bit of a struggle to fit my steam folder on the Vertex 3 as it is quite easy to accumulate numerous titles via steam. With a much higher capacity traditional hard disk, you can keep most all of your titles available locally, but sadly this isn't the case with a drive of this capacity. It's the price you pay for having such blistering fast speed.

You can read a number of reviews stating the theoretical and real world tests illustrating the Vertex 3's speed, but I was mainly concerned with the user experience improvement gained from having one in my system. Copying my 160 gig steam folder was quite fast, maxing out the read transfer rate of my magnetic hard disk at about 75-80 MB per second. After the copy, I proceeded to launch Portal 2 which I had been playing the night before. If you haven't played the game, there are many level transitions that happen between chambers (or in my case deaths).

This drive is built with a SandForce 2281 chip which has a hardware bug. For many users, myself included, this will randomly cause your computer to crash with the blue screen of death. For me, it used to happen every few weeks now it happens every few days. When this problem happens the hard drive will seem to disappear from your computer until you power it off and on again (reset does nothing, because you have to actually cut power to the SandForce 2281 in the drive).

Not everyone sees the bug - it looks like the exact configuration of some computers triggers it much more easily. For the technically minded, each system generates different access patterns to the hard drive and only some patterns will trigger the bug.

Corsair also used this chip in their products and encountered the exact same problem. They issued a recall back in June. The popular AnandTech hardware review site has reproduced this problem and a description of it appears on the first page of their latest review of drives using the SandForce 2281 chip. SandForce has offered to fly in engineers if AnandTech can figure out how to reproduce it more quickly.

Unlike Corsair, OCZ simply lied to all their customers, claiming their issue had nothing to do with the SandForce issue that prompted Corsair to issue a recall, and can be fixed in firmware. Note that "their" firmware is just a renamed version of the SandForce firmware, because the chip manufacturer is the one who writes the firmware controlling the chip. However, after months of firmware updates the problem still occurs.

I haven't even applied the updates personally, I'm just going by the word of all the other people who say they've made no difference. This is because the firmware update process is obscene.

I have a 2011 macbook pro 15". This laptop has the 6GB SATA III interface that works great with this drive. I just got the drive today immediately installed it. I have an OWC adapter on the way so I can put my old 750GB drive where the superdrive goes.

I installed OSX, updated, and then installed office 2011 and let it sync up my 400GB exchange mailbox. Then then testing began.

#%^^&$%& this drive is fast! For grins, I configured ALL office apps, safari, firefox all to open on startup. the machine boots in under 30 seconds and all of those apps are loaded before the desktop even appears!

What a great buy this drive was, and very easy to install!

This is an amazing drive. Incredibly fast.... So fast that when my friend turned it on from a full shut down- they thought that it had only woken up from sleep mode and not actually booted all the way up. Incredible...Super fast installs of applications, my CAD and CS5 software work incredibly faster especially in reading multi GB Photoshop files from this drive... My CAD software is set to automatically back up the files every few minutes and on my old spinning hard disk drive whenever it would backup the file, the application would freeze for a moment while it did its thing...With this SSD....the automatic backups are seamless and completely transparent with ZERO interruption to my work....

IF YOU ARE INSTALLING THIS ON A NEW 2011 MACBOOK PRO with the newest generation of Intel Quad Core i5 or i7 processors DO NOT INSTALL THE TRIM ENABLER THAT HAS BEEN FLOATING AROUND ON THE INTERNET....this is a hack and not supported by Apple in ANY way. The trim enabler will cause your system to lock up momentarily or even completely. The drive has built in support for TRIM and really there is no major need for TRIM on the Mac OSX operating system anyway....Save hours of your time and just leave it be and it will be fantastic to use.
If and when apple supports TRIM for these drives then go ahead....but without their official support you are asking for trouble.

But again....LOVE THIS upgrade.....also- check out an 8 GB Memory Upgrade from either Corsair or Crucial. Both companies offer great upgrades to these Macbook Pro 2011 hardwares and an 8GB upgrade actually boosts the native built in graphics chip from 384MB to 512MB.....this on all versions of the 2011 Macbook Pros that include the Intel Graphics 3000 chip.
