Was just about to post this. Very good price if you've got a SATA3 6Gb board.
#2
SATA3 not SATA2
#3
Cracking price, I thoroughly recommend it as I have one myself. However, be careful over whether to use the SATA 3 port or not. Most SATA 3 enabled motherboards are using a Marvell controller and despite the theoretically better throughput of SATA3, the controller is less efficient than using an Intel controller on SATA 2. I have an Asus P55 motherboard with built-in SATA3 controller but the Crucial SSD is 20% slower when connected to SATA 3 rather than SATA 2.

Thanks for our comment. I don't mean to sound thick, but I am right in assuming, then, that this drive can connect to either a sata 2 or a sata 3 interface, with sata 3 potentially (theoretically?) giving better performance, but that it will work perfectly well on sata 2?

Looks like a good price but is it better than the OCZ vertex?

I dont know what your doing but i have a Asus P55-e Evo and can assure you that the sata3 controller should not bottleneck the drive to a point where the sata2 connection is faster. If i where you i woud make sure its setups right in the bios and that you are using a decent sata3 cable and that the latest drivers are onboard.

I can point you towards a number of expert sites drawing the same conclusion as myself. The Marvell controller is the bottleneck. You may not think its causing you a bottlneck because it is still quick but try switching to SATA2, it will speed the drive up.

Thanks to Dragonseal on the Digital Storm forums for this:

That SATA III 6Gb/s is funny, it's basically downright false advertising. Oy vey, where to start. Well for one there are a ton of different implementation methods used:

Some just use a single PCIe 1.1 lane, this gives just 250MB/s bandwidth, worse than even a normal SATA II port which has 300MB/S bandwidth.

Some use a PLX chip to turn four PCIe 1.1 lanes into two 500MB/s PCIe 2.0 lanes, giving 500MB/s to the USB 3.0 chip and 500MB/s to the SATA III chip. Worse yet is that because of overhead data transfer you're only going to be able to use around 400MB/s of that (to be fair overhead also brings normal SATA II lanes down to 250-270MB/s). Worse yet is that the 500MB/s is shared between the two SATA III ports, so if you use both ports you're back down to 250MB/s per port and a RAID array will top out at 400MB/s.

The last and most aggressive method runs the primary PCIe x16 lane in split x8/x8 mode and steals 8 of those PCIe 2.0 lanes leaving only a PCIe x8 lane for the GPU. Each PCIe 2.0 lane is 500MB/s bandwidth. And funny story! The Marvell SATA III chip can only be connected to one PCIe lane at a time, so the USB 3.0 chip gets one lane, the Marvell SATA III chip gets one lane, and then the other 6 go unused. This starting to look familiar? This is just like the last example, the two SATA III ports get to share a 500MB/s lane and max out at 400MB/s after overhead.

Unless you use two PCIe add on cards, in which case the USB 3.0 and SATA III chips give control of all PCIe 2.0 lanes back and just default to single PCIe 1.1 lanes with only 250MB/s bandwidth.

Oh, and icing on the cake time. That Marvell SATA III controller, it sucks something fierce. No TRIM functionality (!), bad overhead, no cache utilization, little or no RAID functionality (only one of the chip models has RAID capability), compatibility issues, and almost no NCQ capability, just to name a few.

The standard Intel SATA II (ICH10R) ports may cap individually at 270MB/s and limit the sequential speeds of upcoming SSDs some but they beat the snot out of the Marvell offering in every other way. Also the maximum bandwidth for the ICH10R as a whole is much higher, Lilim pushes over 800MB/s which is twice what the Marvell chip can manage.
And the Crucial RealSSD C300, the only SSD currently out with sequential read speeds higher than 270MB/s? Its performance plummets to unacceptable levels without TRIM support, so have fun running that on the TRIMless Marvell SATA III.

Morel of the story: don't waste money on SATA III 6G/b motherboards, they're all a scam.

Now if only they reduced the price of the 128GB model too.

Something to bear in mind is you can RMA this drive to Scotland once the retailer refuses to deal with you. Unlike OCZ, Corsair, etc that require international postage.

In short, yes.

The OCZ has better write performance, but that means little when nearly everyone uses SSD's as their OS/Apps drive.

Thats an interesting read Lowtrawler. I am looking at getting a new PC and was thinking about a SATA III SSD but thats really put me off!!

Do you (or anyone else) have any idea when SATA III is going to be properly supported by the motherboard manufacturers? Are there any new MoBo's in the pipeline?

Good point I've returned a 12 year old graphic card to Crucual under a lifetime warantee, no reciept etc.They were fantastic! No postage to pay and a new £200 card sent to me in days.

Same with an old SD card they paid market value of £10 for an old 1G card that failed.

Good customer service.

Intel expect to issue a chipset that fully supports SATA3 by the end of next year. I believe that some AMD boards are already fully SATA3 compliant but haven't really checked this out.

Thanks for the reply. I have already ordered the new PC and am dipping my toe into the SSD waters with a Sata II SSD (Intel X-25M).
