SSDs are great, mostly. Pricing is coming down, performance is going up. Only thing that occasionally worries me though is reliability.
I owned another SSD here known for competitive pricing and decent (but not stellar) performance: The M4... Looking at the reviews here initially, it looked great. But on closer inspection, there were quite a few stories of instant death after x months of ownership. Firmware updates fixed a lot of these but there were still quite a few on their own forums where the firmware was not the issue. Some M4s still died regardless of having the latest firmware (well, the latest-latest version has issues now, so the one before that.) With all of these reports I couldn't get over the feeling that my SSD was a ticking-time-bomb. Or at least a time-bomb in a lottery of possible ticking-time-bombs.

So I looked around for an SSD that combined reliability, performance and to a lesser extent, pricing and availability. I was looking at the Samsung 840. Even per-ordered it for a couple of hundred dollars more... But it didn't arrive on the estimated date (or at all).. And it was a couple of hundred dollars more.. I could have gotten the 830 but I wanted the latest, which the 830 wasn't. It was also a couple of hundred dollars more.

Which let me to find this model, the Plextor M5P. A few things that made me decide on this one: the 5 year warranty (nice but not enough), the 2.4 million hours MTBF rating. (1.2 million more than the M4), Toshiba Toggle NAND --known as the Gangnam Style of NANDs. ("Toshiban GangNAND Style" is their official tag line) Apple actually uses Toshiba NAND SSDs when they're not using Samsungs. So you know it's good --or at least hipster-glasses-wearing-cool.

Plextor isn't a huge name in SSDs, but they've been making some fast and reliable drives for the last couple of years. Lately they've started to compete on price as well - enter the M5S and M5P.

For your average consumer, any mid to high end SSD is going to be fast enough. You just will not see a big difference outside of synthetic benchmarks. Gaming, browsing, photo editing, and office work don't demand the sort of speed needed to highlight the difference between fast SSDs. Faster drives are great, but companies need to focus on reliability and quality control, which is where Plextor shines.

Top-tier performance, there are only a handful of faster drives on the market
5 year warranty
Reasonable pricing
Plextor has a history of reliablility

Uses new 19nm NAND. Smaller processes tend to mean lower endurance, although Toshiba is rumored to rate this memory at 3K, just like their previous line.
Anandtech's testing showed some performance inconsistencies under non-consumer usage patterns.

I bought an Intel 180 gb SSD for my smaller laptop, and that one wasn't rated really fast. When I ran the windows experience index, the HD number came back as 5.8.

I wanted a new SSD for my main laptop, a Toshiba Qosmio that had an original 500gb Hitachi HDD running at 7200 rpms. My computer is an I7 Core with 8 gbs ram installed. Anyway, I did a lot of research and had 3 SSDs in mind. The OCZ Vertex 4, the Samsung 840 Pro, and this Plextor PX-512M5P in mind. I did a lot of research over 2 days, looking at all the reviews on the Internet, specifically the ones from Tom's Hardware and Anandtech. They do great research. The OCZ ranked the highest in terms of over performance but the research I found indicated some inconsistencies over random write vs sequential write, where the OCZ dropped drastically. The Samsung ranked among the highest in terms of performance and reliability.

I wanted the Samsung but Amazon had it sold out, and it was $570 dollars for 512 gb. The OCZ was $429 but in some of the research articles I read, OCZ had the highest rate of return, meaning customers returned them. It was about 10% and Samsung and Plextor were in the .25% range. Now OCZ did have some firmware updates that you can apply which supposively fixed the problem but I wanted a SSD out of the box that I didn't have to worry about updating the firmware. As you can see in the other reviews for OCZ, the vast majority of people love it, and have had no issues.

Plextor has good consistency and reliability and performance, and I didn't need the fastest SSD so I opted for the Plextor. Believe me, as what everyone says, a good SSD blows a regular HDD out of the water. Do not be scared of the complexity of cloning your HDD to SSD.

This is all i have to say--

90-95% as fast as the best drives out there
Rock solid build quality and support
Real world experience based on a 1366 i7 950 with 12GB of Kingston 1600
This drive could and will outperform my cpu and ram, will last me 3-5 years, and then be resold to kick ass in another persons machine

Injected a new lease of life into my older laptop (Win 7 Pro 64bit, Core Duo 2GHz, 4GB RAM, SATA II). For me, the performance gain of the SSD is worth more than buying a new Core i7 machine with a conventional HDD.

Boot up is very quick. I use the machine for some SW development work and noticed significant performance gains (even though I can't use the M5 to its full potential due to the SATA II limitation of my machine), e.g. when compiling code, running a local MySQL server, or running a virtual machine.

So far, no issues with reliability or wake-up from sleep/hibernation. Main reason for purchase was Plextor's apparently good reputation regarding reliability. Bought this as a replacement for a Crucial m4 512GB drive, which had various reliability issues.

Update May 2013: After 4 months, the SSD started to show signs of failure (disk controller errors in the event log, non-correctable error count increasing in the SMART data, blue screens, some data corruption) under FW 1.03. The SSD was then replaced on warranty. The new one worked flawlessly for 1 month, and has now started to show the same signs (original FW 1.03, then updated to 1.05). This was in a different laptop in order to exclude other possible problem sources (though the CPU and chipset of both laptops are exactly of the same make and model - Intel Mobile Core 2 Duo T7300/GM965/ICH8-ME). This is after only 400GB of data writes to the disk (according to the Plextool software).
