I'm using a Crucial M4 in my Linux desktop and I'm installing a Crucial M500 in my late 2011 Macbook Pro. So I like Crucial, but I wouldn't touch the V4. Crucial appear to have a lot of experience with the Marvell controllers and I've heard good feedback from most M4 and M500 users and also for their earlier drives like the C300.
But not the V4 which uses an older Phison controller. There is a huge thread on the Crucial forums regarding problems with this drive and while there are some suggestions that a firmware upgrade might help, if you take a quick look at what that firmware update might involve (not as simple as the m4 and m500), then you would want to steer clear of this drive.
For a few dollars more you can get something better and there are a lot of options.
I wouldn't go for anything from OCZ right now either. While some have claimed that their more recent drives are a great improvement over the older ones, it appears that they have now filed for bankruptcy - so good luck getting an RMA or any other support if you have a faulty drive.
Perhaps Toshiba will purchase the assets, but that doesn't mean they will accept the liabilities for any OCZ branded drive.

Edit: perhaps I should mention that a thread on support forums doesn't always mean a bad product, as sometimes you find a small number of users that make a lot of noise and/or post under multiple logins. But in the case of the V4, the evidence suggests that this drive should be avoided. At least Crucial provide support forums and allow reasonably robust discussion about problems with their products - not every SSD vendor does this. Do some searches and decide for yourself.
Second Edit: I don't think Crucial even sell the V4 these days and there are some reports of people RMA'ing the V4 and getting an M4 in return (for no extra cost). Perhaps the ones on ebay were recovered from the bottom of a dumpster?
