5 out of 5 eggsGreat drive!

Pros: Easy physical install, easy OS install, screaming fast. I use this as my primary OS drive. I install all software to this drive, but I redirected my temp and data drives to a RAID array to reduce the number of writes to the disk, so as to prolong its life. Software starts up *fast*, and that's what I wanted.

Love it. Wish I had two...

Cons: None.

Other Thoughts: I installed this in a desktop machine as the primary HD. There are slots this small in the chassis. It would be nice if they included some mounting brackets for desktop use.

5 out of 5 eggsMost stable crash free SSD period!

Pros: Stable. Never crashes never had to reinstall not once.

Cons: have none to report.

Other Thoughts: I had this in my notebook "G2K-A1 for about a year. from off to desktop was under 5 seconds. Turning off was the same. I put off installing it in my desktop overclocking machine only because i loved the way it makes my notbook work. well i bought other SSD's to test in my oc machine they all failed. ok I took the hit and removed it from my notebook and installed this in my desktop with the Asus Crosshair IV Extreme, Asus 5970 with tri-fan, Asus 4870 X2 trifan, liquid cooled Phenom II 1100 B.E., liquid cooled VDD,NB,SB,Lucid Hydra in a loop, Thermaltake SwordM case modified. Lets just say on my first attempt it was Amazing. Thereis alot more I have done to this machine. This SSD was the single most important upgrade period my Future mark vantage scores ranged from P26454 to P29724 before SSD after it went to P36670 that alone made me very happy i put it in. after tweaking windows 7 64 a from some very helpful hints from others comments and tweaking now at P44693.WOW!

1 out of 5 eggsMTBF 1 million hours Really?

Pros: Firmware update with trim support; Corsair forum has some good tips for optimizing in various OS's. Advertised to have 1 million hours of life.

Cons: Bought 2 of these from newegg. These were and still are one of the most expensive 256GB ssds sold.

One year later and one failed, it just started to be randomly recognized by any computer's controller. Not a good thing for a boot drive. RMA went fine with Corsair. HOWEVER the replacement, under warranty replacement, is refurbished with an older fimware. Worse, the firmware that supports TRIM refuses to install on this drive. IS this the same P256 model that I easily installed the same firmware update on 2 drives nearly a year ago? Also I do not think a refurbished drive should be shipped as a warranty replacement unless it has the most recent firmware on it or at least can be updated like the new ones. Sorry Corsair you dropped the ball on this one.

2 out of 5 eggsSomewhat fast but...not really worth the money

Pros: The most energy efficient SSD in the market, fast read/write for large files, somewhat steady, supports TRIM, solid drive no moving parts blablabla...

Cons: I/O for small files (4K random) is on par with 7200 disk drives, nowhere near the performance in this category of other SSDs. I think it's because of the low frequency of the samsung controller, but I paid more than six hundred bucks for it, so much for money well spent.
Also some weird problem comes up from time to time, but can easily go away by simply rebooting the drive.

Other Thoughts: They claim to have garbage collection but I have never seen it work.
My laptop has i7-620m, and booting up takes from 30 to 40 seconds, which is about the same as my previous 7200 disk drive, I don't see any significant performance gain in this case.
The only performance gain is when I try to start Firefox, it used to take me more than 10 seconds now it's usually less than 5 seconds; also sometimes virus scan takes shorter amount of time, but other than that it's not worthy of the extra money.

5 out of 5 eggsDefinately a MUST BUY!

Pros: Purchased this drive for my dying 3 year old Sony Vaio Laptop. This drive breathed new life into the laptop that I use every day, and for the past 2 months, the laptop has run faster, cooler, and has extended the battery life by 75% due to the low power consumption.
As of yet, I have not had any issues with this drive, and it continues to perform as it did the day I bought it with no performance decrease.

Cons: none

Other Thoughts: A definite buy. I purchased the drive when it was on sale for $525.00. I would buy it again at full price too. it is well worth the expense!

5 out of 5 eggsBest SSD Series I've used

Pros: Just like most SSD's this one is blazing fast. One of the few computer upgrades that provide very noticeable performance improvements upon installation. This is the second Corsair P series drive I've bought and I'm very satisfied with their long term performance.

Cons: There are several caveats for using SSD's that might not be obvious. First off, quick formatting is the way to go otherwise you will be writing zero's across the entire drive and thereby slow down the drive. Also 'secure' erasing may reduce long term performance.

Other Thoughts: Works very well in OSX and if you can afford it get it!

4 out of 5 eggsTRIM update for P256

Pros: See below

Cons: See below

Other Thoughts: If you have a P256 made before Corsair included TRIM firmware, you need to do a firmware update (or Corsair will do it for you through RMA). See [URL=http://forum.corsair.com/forums/showthread.php?t=83833&highlight=make+dos+bootable+usb+windows]for the update steps[/url]. If you don't do the update, your drive will die. Usually you get CHKDSK prompts before it dies, but not always.

5 out of 5 eggsFantastic

Pros: Nothing that nobody has already said, it lives up to the hype and I will never go back to the platter again.

Cons: Had to flash it to support the Win7 TRIM command, it ended up being easy enough to do but at the time I'm writing this review, the new firmware should be included, so probably a non-issue.
If you do have to flash it, the corsair flashing app may give you an error that the drive is locked, you'll have to unplug the drive's power for less than 5 seconds and plug it back in to unlock it to enable flashing. I know, weird huh? Anyway, write speeds went from 19MB/s in crystal disk mark to 180MB/s. So clearly I'm no file system expert but obviously I didn't treat the drive correctly and to corsair's credit, it was easy to fix on my own.

Other Thoughts: Just buy it, it's worth it.

5 out of 5 eggsFollow up with numbers

Pros: As everyone had commented - FAST!

Cons: None.

Other Thoughts: Follow up - I've been using this in my ASUS notebook as the primary drive for 4 months. I installed Diskeeper 2010 w/Hyperfast and have suffered little or NO degradation. Here are some "stats" using ATTO disk benchmark:
Transfer rates Mar 2010 vs Jun 2010 (write/read)
4kb = 55762/70674 vs 57933/78416
512kb = 175448/223231 vs 175448/217356
1024kb = 173932/220934 vs 174686/222768
8192kb = 175831/216044 vs 180967/226050

Now compare these to my other hd, WD 320gb:
4kb = 46986/45056
512kb = 65472/65154
1024kb = 65632/64527
8192kb = 65712/65154

Now you SEE FAST! I thought the WD was a pretty good drive until I install this SSD. After you use an SSD everything else is slooooow.

5 out of 5 eggsVery Fast and Reliable

Pros: I own three of these P256's. I have two in a RAID 0 cofiguration in my ASUS P5E3 Desktop(Win7 64 bit WEI score=7.9). I have another one in my new ASUS G73JH-A1 Laptop(Win7 64 bit WEI score=7.4).

Cons: Price and Babysitting -- you have to ocasionally do a secure erase with G-Parted to get them back to top notch performance. Trim commands work with single drives and Win7, but don't work yet in RAID(multiple drives) cofigurations. I will be very happy when the RAID controllers allow the Trim command to be passed through to the SSD Drives.

Other Thoughts: They really shine in my ASUS G73JH Laptop!!!
