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.

What's in the box

Main Unit X 1, Welcome Note X 1, Assembling Kit X 1.

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

UPDATE 9/5/12

A month since the last update and still going strong! Zero problems so far, still have 100% drive life remaining (according to S.M.A.R.T.), and I've stopped even considering the possibility that anything bad is going to happen to this drive. My notebook may be heavy and chunky compared to today's ultrabooks, but with my Vertex 4 in it it's a true road warrior and I've been commuting with it to campus now that school has started up again.

I'll see you again at the six month mark if all goes well!

UPDATE 8/6/12

It's been over a week since installation and I haven't had a single problem. Any issues I mentioned in my review seem to have been one-offs and have not repeated themselves. As a result, and as promised, I'm bumping my rating up to 5 stars. I've also changed the title from "Solid but not overwhelming improvement in my system" to "Solid improvement in my system", along with a few references to the title in the review itself.

I notice the price of this drive decreased by about 13% (my inventive way of indicating a price shift without getting filtered by Amazon) since I bought it about ten days or so ago. I'm not surprised since Samsung's 840 Series drive at this same capacity recently dropped in price to where this Vertex 4 is now. The SSD market is highly competitive, and as drives get ever cheaper there's less and less of an excuse not to pick one up.

In the past week I got around my instrument loading problem by switching to a mode that allows me to only load the attack portion of each sample to RAM and stream the remainder from the drive. Since SSDs excel at rapid access times (around 0.

I bought this for my early 2011 macbook pro and mid 2009 mbp and it works great but there are some steps to getting the drive up to date and working.
**UPDATE** works great with Mountain Lion 10.8

Here are some instructions on what to do for people who want to know about making this drive work with the mbp.

0. Backup all data you want from your old drive because you wont have it anymore after you remove it
1. take out old drive and replace with your new SSD (look for youtube videos on how to do this)
2. power on the laptop while holding the "option" key
3. connect the the internet and choose internet recovery
4. when you get into the install screen open disk utilities and select the drive
5. create a new (1 partition) and format your new drive as Mac OS Journaled
6. close disk utility and install Lion onto the drive

ok great now your drive is working and the OS is installed, but the drive is NOT updated to the latest firmware (helps to drive work at its best)
(just a warning this is more advanced)

7. goto OCZ's website for the latest vertex 4 firmware (please read all their instructions on how to update, below is my self-experienced abridged version)
8. download their OCZ Tools utility and burn it to a disk (dvd or CD, i used toast to do this but you can use disk utility also-> for help google "burn iso image osx")
9. restart computer holding option key again and choose to boot from the disk
10. wait for computer to reboot, your touchpad and Wifi wont work... so you need to plug in a USB mouse and connect via ethernet (MUST have net for this to work)
11. click the mac update tool on the bottom bar
12. make sure it is asking to update the vertex 4 (will say y/n)

OCZ's new Vertex 4 drive is probably the fastest current SSD under most common consumer usage purposes. It is blazing fast and has none of the blue screen of death (BSOD) issues of previous drives using Sandforce controllers. OCZ is now using a new Marvel/Indilinx controller with 25nm MLC NAND flash memory. Therefore, OCZ is confident enough to give this drive a 5 year warranty. This is my second SSD and it blows the previous one out of the water. Be aware that almost all of the negative reviews on this drive are from before the 1.5 firmware update (which is now preinstalled).

Right now, the top three SSDs (best selling and best reviews) on Amazon are the OCZ Vertex 4, Samsung 830, and the Crucial M4. The Passmark benchmark scores are as follows: 3589 for the Vertex 4, 3230 for the Samsung 830, and 2409 for the best Crucial M4. Passmark averages all submitted test samples so it is not very sensitive to outliers.

The Vertex 4 has an amazing 120k input/output operations per second which is 30-40% higher than almost all other drives and it has great access times. The sequential write which was a weakness is no longer so due to the firmware updates (it is actually now a strength). But keep in mind that 95+% (perhaps 99+%) of the time you will be reading from the drive and the read speed, in particular random read, is where you'll see almost all of the speedup. Even if you write on the drive often, there are almost no sources you can draw from that will use up all of the write speed of any newer generation drive. If you are downloading from the internet (even if you are on a 100Mpbs T3 line) you won't come close to the write speed of a standard hard drive.
