OCZ’s Vertex Limited Edition Review & SSD State of the Union

OWC - Hot on OCZ’s Heels
Other World Computing, a well known Mac parts reseller, is now also an SSD manufacturer with its own SF-1500 based product.
It’s called the OWC Mercury Extreme Enterprise SSD and is identical to OCZ’s Vertex LE. OWC appears to be a bit behind OCZ as the drives they’ve been sending out still have the older version of SandForce’s firmware. OWC’s pricing appears to be on-par with OCZ’s Vertex LE, but I don’t have final word on availability. Update: It looks like drives are actually available! No word on what firmware revision is shipping on these drives though, I hope to have that information next week.
OWC's SF-1500 sans supercap
The OWC 100GB drive I received performs similarly to last year’s Vertex 2 Pro and today’s Vertex Limited Edition but it’s still using the older firmware. I’m shipping it back to OWC and will hopefully get an idea of final pricing, availability and configuration shortly.

The Sandforce Controller has hardware AES encryption, which could be used with OCZ Toolbox (which is not available).It's a self encrypting drive. No CPU Performance wasted with software encryption.
Why doesn't the Vertex LE support FDE (TCG OPAL Standard like a Seagate Momentus 7200 FDE.4)? The BIOS ATA PWD is passed to the drive, alternatively Pre-Boot Utilities like wave can be used.

It's kinda sad that they will not at least replace the drive with an equal value SSD, I suggest to anybody considering buying any OCZ product to read through there forum before making a purchase!!! People are reporting waiting seven months for warranties on the Vertex series? Today more than ever people are not getting what they paid for and to even post a review of there product is a slap in our collective faces. But I guess Aandtech is selling out too as they have there advertisement up top of this section LOL!NandFlashGuy - Friday, March 12, 2010 - link
Hi Anand,I think your characterization of all IMFT flash as equivalent creates a false idea of quailty equilvalence for readers.
"It’s uses a standard Indilinx Barefoot controller but is paired with IMFT 34nm flash branded either as Intel or Micron. It’s the same flash that’s used in the X25-M G2s."
Intel does not sell enterprise-grade or SSD Nand to competitors. It does do more testing on the Nand used inside the X-25M G2s, ensuring it meets a higher quality level.
While nothing prevents SSD competitors from buying USB-key grade Nand and using it their SSDs, it's incorrect to call it the same Nand that Intel uses.

Well, my 200GB LE lasted one week -- picked it up last Sunday, and now it's so dead the BIOS can no longer even find it. That's one seriously expensive paperweight...deBlanc - Friday, March 5, 2010 - link
Has anyone tried a Raid 1 (mirror) with an SSD and an HDD? I have a customer with a Dell R410 server which has very limited expansion capabilites, only one expansion slot which has a 4 port NIC in it. They are starting to run into disk I/O issues. Short of buying a new server, I was thinking of Raiding a 500 GB OCZ Colossus with a 500 GB Seagate 7200.12, the idea being much faster reads with failover to the HDD if the SSD bricks. I can't afford to buy the SSD to test this out. What do you experts say?Thanks

Overclockers UK has confirmed with Crucial that the 128GB version of the drive has a far slower write speed. They've been told that the write speed is up to 140MB/s.The details are on page 1 here: http://download.micron.com/pdf/datasheets/realssd/...">http://download.micron.com/pdf/datasheets/realssd/...
Compare this to 235MB/s sustained write on the LE, and 250MB/s max write, and there's no competition.
Yes the C300 still has amazing read speeds, but I think the LE is the better all-round performer.
Unless we find out that the numbers we've been seeing on the net for the LE are for the 256GB version and have been erroneously attributed to the 128GB version as well.
I had the LE on order, then cancelled it to order the C300, then found out that the 128GB drive has mediocre write speeds. Talk about a mess!

I contacted the folks at SandForce for a comment on the un-ceremonious death of the OCZ test drive. Below is my question to them, and their response:My email to SandForce:
Dear SandForce,
This is more for the blog community, than it is for me personally (although I am considering Enterprise SSDs for our database servers). I don't think it warrants your phone time. If you can simply prepare a statement in reaction to the test drive going bellly up at Anantech's test center, which I can post, I think that would be more than enough.
Here's the main concern out there:
1. CTO's like me are seriously looking at these drives to consider putting their databases on (SaaS based applications can benefit from the performance improvements).
2. We are deathly afraid of the reliability issues, so when initial articles about SandForce controllers came out with the emphasis on reliability, everyone was cautiosly elated.
3. We see a follow-up story on Anantech (arguably THE source of impartial news on hardware), show that the OCZ drive just "died", and I think it's safe to say, there's significant concern.
Yes, everyone knows it was a pre-production drive (Anantech makes that clear), but the cat is now out of the bag, and without a proper forensic investigation, I'm concerned this would happen witth a production drive. Hence my reaching out to
your firm for an explenation beyond "Oh don't worry guys, that was pre-production hardware". As you know, our community is comprised of smart people, and that type of answer just doesn't cut it.
What say you ?
Their answer to me:
Dear Carl,
We appreciate the inquiry and definitely appreciate your concern. It was appropriate that Anandtech highlight the drive that failed was a pre-production drive. The drive used Beta firmware, which by definition, had known issues.
Since then, SandForce has released its ‘release candidate’ firmware to our customer base of SSD vendors with the intent for them to run their qualification process on the drives and intensive tests for stability. We have received positive feedback so far. We’ll take any issues that we hear of (and any that we find ourselves) and release a ‘mass production’ version of firmware with the intent for end user customer shipments and usage. We’re confident that with the large number of leading SSD vendors in both Enterprise and Client markets that are qualifying drives based on our silicon and FW, in addition to our own robust testing capabilities, production drives based on SandForce will be of the highest reliability.

Looking at a Japanese retailer's listing for the RealSSD drives at http://bit.ly/clxvoa">http://bit.ly/clxvoa, the write speeds of the 128GB and 256GB versions differ by around 50%!Random 4K Write:
128GB - 140 MB/s, 30K IOPS
256GB - 215 MB/s, 45K IOPS
Out of curiosity, which version was tested in this article? The numbers are close to the listed 128GB specs, so that's what I'm guessing. What could result in such a big difference in write performance in this as well as other drives(DRAM size?)? Or is this just some retailer manipulating the numbers to sell a more expensive part (work in research long enough and you get to know the amazing things possible through the use of normalization)...

Don't suppose C300 vs. Vertex LE review is around the corner?
