I have only had this drive for 4 days now so in terms of reliability there's nothing I can say but the 5 year warranty gives me peace of mind.

I've been using this drive on a daily basis for seven months now and it works like a champion!

Time will tell but with a 5 year warranty Plextor feels like they are putting thier $$ on the line which makes me feel good that this drive will last and whether a few bytes faster or slower is not as important as reliability - so what if it's 10 bytes faster if gets an error and blows up a OS that's much more important to me - this drive has ECC built into it and from the data they show on the site spec page it looks good and it has bulit in security with AES - I was using a Crucial M4 but I could not get the firmware update to load so I took it off line and replaced it with this drive - I didn't feel any speed difference but I feel better ---

I had looked at five potential SSDs to use in my laptop (the Samsung 830, Samsung 840, Samsung 840 Pro, OCZ Vertex 4, and this one, the Plextor M5P). I really wanted the 840 Pro, but I just couldn't justify the additional cost. Based upon performance tests and reviews I selected the Plextor, and had high hopes for it. But my hopes were dashed, and after spending many hours trying to get the drive working I am sending it back. I have a Dell XPS L702X laptop, running Windows 7. The drive was found by the BIOS, but I just couldn't get it to be seen by Windows. I tried it in another (desktop) machine and there were no problems ... I was able to format the drive, which I thought might help on the laptop, but no luck - the drive wasn't visible in Disk Management. I tried the disk in both drive bays (the laptop has two bays), and updated the drivers on the laptop. I also spent about an hour with Plextor support (in a chat window), but this was completely useless. They told me that they would have "tier 2" support contact me, but after six hours I have still heard nothing from them. I have difficulty rating the drive, and I think it's somewhat unfair to rate it poorly just because it's not recognized in my laptop, but I'm not sure what else to do ... it indicates to me that there are compatibility issues, and I am reflecting the Plextor online support capability in this rating. I'd still recommend this drive if it's compatible with your machine! By the way, I'm going to get the Samsung 840 instead of the Plextor.

Like many, I wanted to breathe some life in my mid-2009 13" MacBook Pro (MBP). In the last year I maxed out the RAM (from 4GB to 8GB) and HDD (from 5400rpm to 7200rpm).

I'd been on the fence with an SSD upgrade because I'd been considering a newer laptop, but a recent upgrade to a new DSLR (Nikon D700 -> D800) meant larger image files and required me to squeeze more horsepower from my laptop.

Another reason for my hesitation in upgrading is my MBP is SATA II (3GB/s) and I knew I wouldn't get the blazing fast read/write speeds these newer SSD SATA III drives are advertising. But I figured any boost would be a huge improvement over my current speeds.

I'd considered a Samsung 840 (consumer) 250GB drive, but Amazon was running a special on this Plextor so I pulled the trigger. If not for the price special and 6GB more storage, I probably would've stuck with the Samsung since I probably wouldn't realize the full advertised speed boost in this Plextor due to the SATA II bus limitations.

The cloning process was very straight forward albeit slow due to having to use the slow USB 2.0 port (SSD in a SATA enclosure). You can do a search on the web for instructions on cloning your original drive (for free) simply using the OSX recovery process for your given version, or your favorite cloning software.

With the SSD installed, read/write speeds hover over 200MB/s which is a little over 3X my old drive (60MB/s). Definitely short of the M5 Pro's advertised speeds (540MB/s read, 460MB/s write), but a nice improvement over my old drive. Working with large image files is definitely more tolerable than before-- very comparable to my workflow with my old camera and HDD.

This drive was an upgrade for my 2011 Macbook Pro and it brought new life to the machine. My boot time went from 1 minute and 20 seconds to 18 seconds!!!! I installed Adobe CS6 Master Collection in around 10 minutes and Photoshop opens so quick it doesnt have time to bounce in the Dock. I did upgrade from a 750 gig 5400 RPM drive so the speed increase is extreme. I was able to upgrade to the newly release firmware very easily. I chose this drive because of the controller with built in ECC and Plextor's 5 year warranty. I have only had this drive for 4 days now so in terms of reliability there's nothing I can say but the 5 year warranty gives me peace of mind. Bottom line, if you are looking for a blazing fast SSD, then look no further!

Let me first say that I just ordered this moments ago. It is currently on sale for $200.
If you're looking for a 256GB SSD then this is the best bang for your buck.

The only other model truly in the same class, in my opinion, is the OCZ Vertex 4, released back around April. The Plextor M5P is a bit newer, has similar benchmarks(better read/write speeds where it actually matters), and uses the latest Marvell 88SS9187 controller(not a huge deal as the Vertex controller, Indilinx Everest 2, was built by Marvell). It's another bonus that this thing is supposed to last, on average, 20% longer than the Vertex.

If it were marked at $250 then I'd still believe it wins over the Vertex.
