Just thought I'd share my experience on this product. I bought it a month ago after considerable research online and in stores. It was getting unbearable to wait for the HD access on apps and large spreadsheets to load and process. Now everything works like greased lightning (but some large data sets still take a while to load - undoable without the SSD).

The only drawback is price of the new SSDs. I could only afford the 256GB but would have loved the 500GB since I was already using a 500GB traditional spinning media drive. It was a good exercise to downsize my info and consolidate the data to an external firewire800 drive.

This almost makes the macbook pro an instant-on laptop like the new macbook air.

A full review (with photos) is posted here: [...]
An excerpt from my i7-920 Workstation Build Review of 21 November 2009:

""System drives hold ONLY your operating system and your programs. They don't need to be large, but they benefit greatly from being fast.

I'm currently using a Western Digital 300gb Raptor II SATA II drive. 3 years ago this was the fastest system drive available. Soon I'll replace it. With what? When the SSD market bottoms out, which will be very soon, and they offer at least a 256gb SSD (solid state drive) with 200mbps+ transfer speeds for under $300.. then I'll get one. I might get two and put one in my laptop.

Currently SSD's are not as reliable as I'd like them to be. The speed is certainly there, but they're still working out mystery phantom data losses and other issues with the controllers and firmware and for something as important as a system drive I'd want more refinement and even more reliability.

IF I had to replace my system drive today I'd be torn between three types of drives. Another Raptor exactly like what I have, an Intel x25 SSD (the 256gb model is currently about $500), and one of the new SATA II 6gps terabyte drives which are even faster than the Raptor. You WILL notice even a bit of speed increase in a system drive. If you're interested in performance this is where you should spend some money.""

Introduction

Looking back at my own words I predicted a few things, and should have predicted another. SSD's are indeed becoming mainstream, they have become a lot more reliable, they're a lot faster than even back in November, and they have dropped significantly in price. A fast system/program drive very much affects total system performance.

I bought this hard drive and loved the speed boost I got on my Acer 1810TZ. And I didn't even have to sacrifice too much capacity. But then after using it for 3-4 months, one day it started a slow descent into dysfunctionality. Within a day, my laptop would regularly blue screen. I was able to get my data off the hard drive before it went completely kaput. A bad piece I thought and I got it RMA'ed by Crucial. A month or two later, once I had the time, I switched back to the SSD. And here I am a month later back to the same slow descent into dysfunctionality. I'm not sure why, but this Crucial drive is not reliable. I don't recommend it. Maybe it's because Crucial is a flash drive maker and not a hard drive maker so they don't know how to qualify / test their SSDs to hard drive usage pattern standards (this was suggested to me by one of my IT guys). But I would absolutely NOT buy one of these again. I love the speed boost, but I can't stand the unreliability.

The title says it all: 351 MB/s read 210 MB/s write.

My office Intel X25-E (only 64GB and the same price, although SLC) gives 240 and 170.

This is the only SATA III SSD on the market, and it shows the potential of this drive.
I can compile a huge project in Visual Studio 2010 in 1/10 th the time it takes on a regular
drive. Ditto for videos. Random read writes are an unbelievable 50 times faster than a WD Velociraptor.

Other than a PCI-E based SSD (which are rather untested at this point), this is the safest bet.
And Crucial is as solid a memory company as it gets.

Other stuff:
You need SATA 3 cable (and a good one; if you are getting low speeds it is almos always because of a bad cable)
or the wrong port.

I updated the firmware without problems (or wait till they do it on the production versions).
Of course you need a SATA 3 motherboard, such as the Asus P6x58D and a good enough processor or the processor starts
being the bottleneck (say a core i7 975 or 980x).

I replaced a 7200 RPM hybrid ssd drive, the one with 4GB of SSD storage to speed things up. I had that in my two week old new 2011 model quad core i7 15" macbook pro and 8GB of memory.
For the basics, I timed my bootup, and how long it took me to get an app connected to the internet, in this instance Adium. Cold boot to logon screen with the hybrid ssd drive was 47.6 seconds, and to adium being connected and me being able to double click a contact to send a message, a total of 1 minute 46 seconds.

After I cloned via CCC to the SSD drive, my boot time actually increased. It took about 10 seconds longer to boot up. Everything screamed once booted, but the long boot process surprised me, until a google search showed that I needed to reset the PRAM on my MBP. Once I did that, I just about fainted. From hitting the power button to logon screen is 16.9 seconds, and the total from hitting the power button until I am typing to a contact in adium is only 32.6 seconds. I'm up and running and active in a chat in just over 30 seconds, compared to 106 seconds.

Apps are, as so many have said, nearly instantaneous. Even Outlook 2011 for Mac which always was a slow starter is up and running in about 2 seconds.

Fortunately I had plenty of free space on that 500GB drive, so could still fit my mac and windows boot camp partition on this one, even if I only have about 25GB to spare. That will go up to about 45 to spare since I'll delete my winclone image of boot camp from my hard drive and just keep a copy on an external firewire drive instead.
