Crucial RealSSD C300 CTFDDAC256MAG-1G1 2.5" 256GB SATA III MLC Internal Solid State Drive (SSD)

Pros: These have been awesome. I bought them a year ago for raid 0 and they have been nearly flawless. No degradation, no stutters, nothing. I set them up on Sata II R0 to get better speeds than Sata III, since Sata III didn't have proper raid support -- no fault of Crucial, it's a motherboard thing.

Cons: Not really a con. With all SSD's it's important to update your firmware and set up Windows to treat your SSD's properly to prevent degradation. Many of the problems you see are likely a result of that.
The only con here is price. Two of these were a thousand dollar bomb, and there are cheaper drives available now of better performance. Still, I commend Crucial for these, they were the best at the time and are still treating me well. At this level of performance, "more" becomes irrelevant.

Pros: Purchased the drive in summer of 2010. Drive was lightning fast for about a year

Cons: during the last few months areas of the drive have become corrupt and the drive pauses about once every 5 to 10 seconds causing the system to pause.

Other Thoughts: Crucial support is better than others... however they said it would be 8-12 weeks for them to fix this and or give me a new one. They said they would ship me a new drive however they would charge me full price "if" the problem wasn't covered under warranty. I wasn't going to play those games, i purchased a different drive from another company

Pros: I got these units (I own two) for speed and reliability as well as silence. The speed and reliability are unquestionable - my Win7 box boots quickly and w/o any glitches so that I almost forget it's Win7.
The second unit serves as a primary Photoshop cache - it makes Photoshop a true production tool w/o waits for transforms, color changes or puppet wraps.

Cons: Price? Long term reliability? I have owned these units for more than a year, so I'm waiting for the built-in warranty clock to tick over (not really - that's something in Detroit and iStuff, yes?). I expect to use these for a long time - years - and I have gotten my money's worth in a year of fast boots and excellent Photoshop response.

Other Thoughts: I own two of these units - one is my primary boot drive, the other is my primary cache for windows and Photoshop.
I had to buy a separate 6 GB/s interface card (Koutech IO-PESA230) [no problems with this card/and 2 drives, BTW] even though my mobo (ASUS Tigershark) had an on-board 6 GB/s connection that I was using for my SAS array.
I boot off the C300 whenever a reboot is necessary (once in a blue moon) but, or course, keep an HDD multiple clones of my boot drive in various safes (local and at the bank) - paranoids have enemies, too, you know.

Pros: Fast, reliable

Cons: None

Pros: A really fast drive. It felt that I installed Windows as fast as it took to reboot the machine.

Cons: Still expensive for the size. You're probably going to still want a larger magnetic drive.

Other Thoughts: I find the 2.5" form factor annoying. They still don't fit in standard ATX cases and I'm sure very few people buy these things to slam them into laptops. Although I'll consider this a personal opinion.

Pros: faster than light (screw Einstein) with only windows 7 no extras was 30-33 seconds boot, with everything else I use installed (specifically anti-virus) 35-38 seconds.

Cons: Had BSOD for 7 of my 9 months, finally the drive just crashed (not showing in post). When it finally showed back up (leave attached for an hour or so while pc is on.....tech support advice) my "former" system partition showed as "not initialized".

Other Thoughts: can't rate 0?

Pros: Fast.

Cons: Firmware.

Other Thoughts: Although I've never had a problem with mine, keep in mind that Crucial has had problems with firmware updates for this drive in the past.

Pros: Fast access speeds, Fast Windows load times

Cons: Price

Other Thoughts: Very good drive, one of the fastest I've tested. Scored a 7.9 in the Windows Experience Index for Disk data transfer rate. Installed in my Inspiron 14R N4110.

Pros: - Fast
- Reliable
- No BSOD's

Cons: - Price (at the time)

Other Thoughts: I bought this 9 months ago as a replacement for the stock drive in my Lenovo ThinkPad T410s. This boots Win7/x64 in less than 30 seconds. It has been very reliable. I run Truecrypt as a boot loader and have had no problems, performance or otherwise.

Pros: This drive is a beast. Access times are rediculously fast. Never had anything like it before, but now that I'm here, I will never use anything other than SSD for boot drives ever again.

Cons: Took a firmware update to work in my laptop, (Early '11 MBP), Trim was/is not officially supported on 3rd party drives in Snow Leopard, still enabled it anyway, so meh..

Other Thoughts: The reviewer Swansong must have gotten a bad unit. I have a 15 inch i7 MBP from the same period as his, and my hard drive has been ROCK solidthrough the entire duration. If he has the technical acumen he claims to have he should know that a tweak can be downloaded to enable trim in Snow Leopard, and if he has already done that - then he is unlucky, the drive is bad, and get an RMA already. Too many one star rating based in emotional responses these days.
