Final Words
The first time Intel told me it would be using a 3rd party controller in one of its upcoming SSDs I bit my tongue. Intel tried to justify the decision but all I heard in my head was that Intel was bowing out of the high end race, that Elmcrest was a copout. I have to admit I was wrong. I assumed that Elmcrest wouldn't be even remotely competitive. In reality, the Intel SSD 510 may not be the fastest SATA SSD we've ever tested, but it comes very close. Overall performance is within striking distance of the Vertex 3 and depending on the test, performance can actually be a little higher than the clever competitor. Note that I've only tested the 250GB drive. Intel's 120GB SSD 510 should be measurably slower.
The 510 is most interesting over a 6Gbps interface. Connected to a 3Gbps interface the drive is quick, but fails to distance itself from the high end drives of last year. This is the same conclusion I came to when I previewed the Vertex 3. These next-generation SSDs not only use 6Gbps SATA, they really need it.
My biggest complaints about the 510 actually aren't about Intel's use of a 3rd party controller, instead they are about the drive's lackluster random read performance. In a horrible bout of irony Intel fixed its sequential performance and moved backwards in the random department. Random read performance, as it turns out, has a pretty major impact in the real world.
Random write performance is also pretty low by today's standards, however the impact on most of our real world performance tests is minimal. It looks like we may have hit the upper limit of what we need from 4KB random write performance (at least given current workloads).
Sequential performance is easily competitive with the Vertex 3, and when presented with incompressible data the Intel SSD 510 is easily faster.
Overall OCZ's Vertex 3 is faster, however the margin of victory isn't always significant. Intel would argue that its drive is better tested and less likely to fail. Whether this is true remains to be seen, but history does count for something.
As always, it'll be months before we have a good idea of compatibility, reliability and any long term issues. In typical AnandTech fashion I've already deployed the Intel SSD 510 in a primary use system. The big advantage Intel has today is that its drive is currently available and it seems to work. The performance is good and close enough to the Vertex 3 that if the drive does end up being more reliable Intel could have a winner on its hands.
At the same time, OCZ has been investing tremendously in improving manufacturing quality and validation testing. If the Vertex 3 can launch without any major firmware bugs, reliability or manufacturing issues, Intel's SSD 510 may not have a leg to stand on.
Then we have the other Marvell based designs from Corsair and Crucial/Micron. The 2011 SSD market is just starting to heat up...

It would be silly to return the Vertex 2 (my opinion). Just check out the PCMark Vantage scores in this article. There's little real world difference between all of the high end drives. Without the benchmarks, there's no way to tell the drives apart.But if it's going to eat you up inside, knowing you were just a 2-3 months away from having the latest model, go ahead. I'll be keeping be enjoying my OCZ Agility 2 in the mean time.

"I'm wondering if I should return the [Vertex 2] and just wait for the Vertex 3"I've got a mix of Vertex 1's, Intel G1s, Intel G2, and Vertex 2's in a variety of machines at home and at work.
For workstation usage as a software dev, there's not a heck of a lot of subjective (ie, "it feels faster") difference between them. At this level of disk performance, your machine just isn't waiting on the hard drive very often.
Obviously you may have specific needs. I used to work for a client who had a 8GB database that I was constantly backing up and restoring many times a day in the course of development work. Now there was a situation where raw read/write speeds were king and the Vertex 3 probably would have performed close to 2x faster. For me that kind of usage is the exception and not the rule though.

I didn't see any discussion on internal garbage collection (ie: NOT trim).Does it have any?
In my mind, this will be the key deciding feature between Intel and Vertex 3. Whichever has the better garbage collection without TRIM. Remember, TRIM still doesn't work in a RAID array or in OSX.

+1. I'm really eager for an IGC comparison of the Intel 510, the Vertex 3 and if possible, also of a current firmware version of the Crucial C300 (since the drive still competes very well).In Anand's initial test, the C300 suffered from very poor IGC, but Marvell supposedly alleviated this problem in their new firmware releases. Unfortunately, no IGC tests have been conducted with the 0006 firmware yet.

Hate to do this, but+1.
It's not what's the latest, but what's offers the best bang for buck after upgrades.
Such a review would be immensely helpful.
Although based on the Intel 510 TRIM-test random write results, it may have to wait for the first Intel FW upgrade as the numbers with the shipping FW are truly appalling.

I'm dying to know how it will hold up in my macbook pro. I finally caved and bought one of these 510 SSD's and although it's after the fact, I still want to know how long it'll still be "good" in my system.tim851 - Wednesday, March 2, 2011 - link
If the original X25-M "conroe'd" the market, it seems G3 "atomed" it. In the way that Intel, in their crusade to maximize profits and segmentize the market, designed quite a bit to conservatively.I'm all for it though, because I believe that currently, the last thing SSDs are lacking is speed, so the last thing they really need is more of it. I believe at this point just about everybody would want one, if it weren't for the prohibitively high prices. So if Intel can half the per-GB-price of the G3, I'll buy one for sure!

+1I thought the exact same thing about the 1st gen drive compared to this one. What makes SSD's "feel" so much faster is the random read/write performance. When the 40GB X25-V is so close to matching random read/write the 510 will just "feel" slow, especially once you have everything installed on it. I mean, really, who cares about sequential performance once you have everything on the drive that you planned putting on it?
Anand, please put the current WD velociraptor numbers into this graph. It will demonstrate what I mean.
Glad I didn't wait and got my 60GB Vertex 2...

oh yeah if I just looked I would see the velociraptor numbers... lol its late and I should be asleep... maybe I am? Did Intel just atom their next SSD?Golgatha - Wednesday, March 2, 2011 - link
I think this is a fair criticism. I also only look at the random R/W performance of these new SSDs. I can pull 215 MB/s R/W from my 300GB Velociraptors in RAID0, and use these drives to install all my games on since game loading performance is largely determined by sequential reading of data from the disks (lots of big sequential files), and because I need around 400GB of space currently for all my game installs .Sequential reads for most SSDs are lower than the 215 MB/s reads I enjoy from my Velociraptors in RAID0. I have a Crucial C300 256MB in this same desktop and I also use an 80GB Intel G2 in my laptop; both of these drives are slower than my Velociraptors in RAID0 in terms of sequential read performance. Also, there is obviously a space concern, in that there isn't enough space on either of these drives to install my games to them.
Now for the host OS and all the random programs I run in parallel, a SSD gives you huge gains and the system just feels snappier. This is largely due to random R/W performance. Basically you'd be hard pressed to tell the difference between sequentially reading 10MB of data or less at 215MB/s (Velociraptors in RAID0) vs 320MB/s (my Crucial C300 256MB average speed on a PCIe4x, SATA3, ASUS add-in card), hence the reason that sequential performance of SSDs doesn't matter much to me anymore.
Now if I could get a 512GB or bigger SSD with greater than 215MB/s sequential read performance for less than $1/GB, I might bite on that. So far this product has not come to market, so I'll stick with my Velociraptors until it does.
