1 out of 5 eggsDo _not_ buy this drive

Pros: Works very well until it randomly dies and you lose all your un-backed-up data.

Cons: Dies with no warning or reason and _cannot be recovered at all_.
Tech support will tell you to plug it in and let it sit in the hopes that magic will happen; when no magic happens, crucial tech support will ignore your emails and requests for more information on how to reflash the firmware.

Other Thoughts: Wish I could give this 0 eggs.
After this experience with crucial's amazingly inept firmware and useless technical support, I'll be replacing all the other crucial drives i've bought over the past 2 years with drives from a larger manufacturer who takes the time and money to test out the hardware and firmware they sell and notify people of potential problems.

Crucial - Please don't respond to this review unless you're going to post the command line switch for dosmcli.exe that will let me skip the firmware version check and reflash the drive.

2 out of 5 eggsSave time in the short run, pay it back with interest

Pros: Very fast. Works just like a regular HDD.

Cons: Unreliable, mediocre service from Crucial. You'll love it until it crashes, then you'll regret having bought it.

Other Thoughts: I bought this for about $700 in Summer of 2010, and got nine months of good use out of it. Then it died, fairly suddenly, and with no warning. Crucial made me pay to send it to Idaho and wait until they received it and confirmed that it was dead. Then they mailed me a refurb. Two weeks turnaround, two weeks without a main disk. The refurb died after another four months, same problem, same return policy -- another two weeks without a drive, another reinstall of everything.

The speed of the drive is impressive, but it's hardly worth it if you end up having to reinstall everything every six months or so. I wish now that I had waited for this technology to mature a bit. And I had hoped that a company like Crucial would at least express-ship me a replacement while waiting for my dead, worthless drive to come back to them, especially the second time. But no dice.

1 out of 5 eggsDOA

Pros: It died the day I put into my system, so that was really good since I had just started wiring things in. Had plenty of time to send it back to the newegg.

Cons: Just the Price for the 300 series SSD

Other Thoughts: Considering the price, I was glad it broke very early on.

5 out of 5 eggsAwesome!

Pros: FAST!!! Works great! Enough space for Windows 7, Office, and all other apps. Only user data sits on spinning disk now. This is a very responsive PC. System boots fast and apps open in a blink.

Cons: None.

Other Thoughts: The box indicated the firmware was one rev back from the latest, so the first thing I did was to upgrade the firmware right out of the box, before loading anything. It was easy.

5 out of 5 eggsTest

Pros: A lot better than a hard drive. I can run a game, my Dragon NaturallySpeaking software, and a VirusScan all at the same time with no slow performance with my computer.

Cons: The only con to this device is the price. However, you get what you pay for. Also, it not come with a bracket to install in a 3.5" bay. Fortunately my Scoutmaster computer case came with a free one.

Other Thoughts: Originally, my read and write specs were not as advertised. This is due to my fault due to the fact in my bios I had the device as Native IDE. You have to set this device in your bios to AHCI. The results from changing from native IDE to AHCI were fantastic. In Native IDE the reads were 229 after I have modified the bios to recognize the device as a AHCI device and the reads were 339 after which. Also, the writing performance was improved as well and now it reads at 229.

3 out of 5 eggsSmoking fast but crashes

Pros: Very fast. I use it on a Lenovo X201 laptop, running Windows 7 Ultimate. Substituted it for the manufacturer drive, which was easy. This makes some sluggish Windows applications, and Windows itself, very fast and now I will never go back to spinning drives.

Cons: Crashes. The first drive that I got would crash every day; the behavior is that it would stop accepting reads and writes. There are worst things (it doesn't corrupt data for example) and Windows reboots in 20 seconds with this drive. But it got annoying. I figured I had a defective unit, so I got a new one (also so that I could easily restore my system image.) The new one doesn't crash as often but it still crashes.

Other Thoughts: I'm not sure what the source of the crashes is; whether it is heat related. The crashes are down to one every 3 days, but still it is annoying, e.g., crashing in the middle of a WebEx with a client. I noticed on these reviews that there is a firmware update and I might try it.

5 out of 5 eggsFirmware 006 Update for this SSD

Pros: This drive has a new firmware update (006). The latest firmware is NON-destructive of the data on the drive. The update can be downloaded from Crucial here:

Additionally do NOT use the Marvell driver for this drive. It is OK to load the Marvell Console software, but do NOT allow the driver to load (the Marvell drivers are a disaster and will actually slow down the drive by over 25%). Instead, use Microsoft's embedded SATA driver for initial system load, and then supplement it by installing Intel's latest .inf driver and the latest Intel SATA RAID driver bundle (if you're not using RAID it won't hurt anything) since that will load the latest AHCI driver for the SATA 3 connection. Make sure the connection between the motherboard and the SSD is set to AHCI (or RAID if you're using an array), otherwise the TRIM function can't work. Incidentally Intel's latest RAID drivers allow TRIM to work inside a RAID array (nice!).

Cons: Absolutely none, providing you upgrade the firmware and don't use the Marvell drivers.

Other Thoughts: These drives are fantastic, but there's an even faster version coming by mid-2011.

3 out of 5 eggsSSD is not that great

Pros: Boots windows quickly. Most programs load quickly. Slightly better than my older 10,000 rpm WD Velociraptor.

Cons: This drive causes my system to randomly freeze for about 1/2 second throughout the day.

Other Thoughts: I store my cache on my old velociraptor because of the way SSD MLC technology works. This is not worth the price but I had money to burn.

5 out of 5 eggsFIRMWARE UPDAT 002 !!!!

Pros: Bought this drive last week for my water cooled i7-980x bone crusher system.

Make sure to do the firmware update.

Release Date: 5/20/2010
Change Log:

•Improved Power Consumption
•Improved TRIM performance
•Enabled the Drive Activity Pin (Pin 11)
•Improved Robustness due to unexpected power loss
•Improved data management to reduce maximum write latency
•Improved Performance of SSD as it fills up with data
•Improved Data Integrity
Note: This requires a Low Level Format to the SSD which will erase any data on the drive.
Please ensure that your data is backed up prior to performing the Firmware Update. We are hopeful that future Firmware revisions/updates will not be destructive.

Cons: no cons

Other Thoughts: Next month I plan to use four of these in a raid 0 configuration.
