Revitalizes even older machines

This is a cracking little drive, good value

The firmware was already at 000f when i bought this, so there was no need to update, it loads windows 7 load screen to user logged on *no password* in 8 seconds, which is so fast. with the space, you don't even need to save program files to a alternate hard disk, as i'm still not down to 190gb yet!

I use my old c300 ssd drive with my 2TB hdd for caching on my z68 mobo. I bought this drive purely for my most commonly used games for pure reduction of loading times. I flashed the bios to 0009 with no problems. Installed WoW, SC2, FSX etc and what a difference its made. Very impressed, awesome performance.

Now that's more like it!

I originally bought an M225 from OC, fast delivery etc and the drive was faster but no where near the expectations I had from it, then it failed 80% full and it started to vanish from BIOS during read / write.

I returned the drive to Crucial and they sent me an M4 back. Firmware 0009. This is more like it, much faster than the M225 piece of junk.

Now if only there was 1 of these in terra sizes and cheap, I would buy 4.

Superb drive

Super fast drive. Installed it and updated to the latest firmware. No hitch at all. A breeze to install and use

Don't delay

I was sceptical that a SSD would make my PC that much better. The thing does cost a lot but I think it is well worth it. If SSDs come down in price they could sell by the bucket load. I'd buy another in an instant, which is as long as it takes to boot up with one of these beauties.

Fast & stable.

Just installed this in a new build with i5 2500k @4.3Ghz, 8Gb Corsair Vengance RAM Asus P8Z68-V. Full install on win 7 64bit, lots of device drivers inc X-fi , logitech G13 etc. Boots from bois screen to fully usable OS in 23 seconds! So fast you don't see the loading bar and the windows 7 animation never has time to finish. Using v0009 F.W. Haven't had a single hiccup with this drive. Bought it as wanted to stay away from the Sandforce controller until its problems are sorted. Cant imagine going back to spinning platters again!

Starbase74 2011-10-24

update your firmware!

Crucial have now released 0009 firmware that increases read speeds up to 530mb and lowers boots time and increases 3D mark vantage HDD test scores.

With the sandforce issues it seems crucial have stolen a lead on OCZ.

It is expensive still at almost
