Final Words
Without competing cards to compare to it's difficult to quantify the Z-Drive R4's performance other than to say that it is obviously very fast. With SandForce based SSDs however my concern is rarely about performance and more about reliability. I've often heard that in the enterprise world SSDs just aren't used unless the data is on a live mechanical disk backup somewhere. Players in the enterprise space just don't seem to have the confidence in SSDs yet. Given the teething problems we've seen on the desktop, I don't blame these customers at all.
Ultimately that's my biggest concern with the Z-Drive R4: it seems to be a very solid performer, but it has an absolutely unknown reliability track record. It's possible that by using an on-board SAS controller the Z-Drive R4 will be less prone to random system incompatibilities and a more reliable solution since it is effectively a closed box at that point. That's purely speculation however.
I am curious how OCZ will approach enterprise customers and attempt to win over their trust with the Z-Drive R4. You obviously won't see any Newegg reviews of the product, so OCZ will have to get testimonials from some pretty influential customers to gain traction in this space.
Seriously entering the enterprise market is a huge move for OCZ. Three years ago I couldn't have predicted OCZ would get this far, I wonder what will happen over the next three. One thing is for sure: OCZ will need more than enterprise products to adequately address this market. Hopefully any investments in testing and validation for enterprise customers will help improve the consumer side of the business as well.

And why is that? Because of the supposed high failure rates? Can you supply any real information about this?OCZ has less then 1% failure rate. There may be more then 1% of customers who have "issues" but they aren't related to the drive. User error plays a pretty big role, but of course it MUST be OCZ's fault right?
Enterprise customers are professionals who know how to install serious hardware like this. And if they don't? OCZ will help install it for them on site. That's what enterprise companies do!

I don't believe that 1% number for a second. First of all, I read some return stats from a store that listed the RETURN rate at just below 3%. Secondly, I know of 5 very different systems with Vertex 3 drives in them. All 5 have recurring lockups/BSODs. The people who built and run these systems write their own filesystems. They are extremely knowledgeable. If they can't make them run properly, they are not fit to run outside of a lab environment.That said, I suspect it's as much Sandforce that's the problem as it is OCZ.

I think it's an Intel problem. But NooOoOo... it can't be an Intel problem...geddarkstorm - Wednesday, September 28, 2011 - link
From all the data I've been seeing, it seems to be a SATA III issue, and an issue with motherboards not being reading for such high volumes of data flow. Mechanical drives can get no where near SSD speeds, and I don't think manufacturers were really expecting how fast they'd go on SATA III (almost pegging it out at times, and it's brand new!).josephjpeters - Wednesday, September 28, 2011 - link
Exactly. It's not an OCZ issue, it's the motherboard. When will someone step in and take the blame?Beenthere - Tuesday, September 27, 2011 - link
SSDs appear to be an on-the-job learning program for SSD manufacturers with all the issues that currently exist.I do not however believe they are selling SSDs at low margins.
Enterprise won't use SSDs yet for the same reason informed consumers won't use them - they have serious reliability and compatibility issues. Unless you can afford lost data and a hosed PC, SSDs are not even an option at this point in time. Maybe in a couple more years they will sort out the problems that should have resolved long agao?

I wonder really how much a consumer SSD costs to produce. Saying that slim margins will force companies out of business if there's a big markup on a 128GB is not true. These same drives were $100s of dollars last year and probably still aren't good value today. Unless you're saying consumers are waiting for the .50c/GB drive.josephjpeters - Tuesday, September 27, 2011 - link
It's roughly 20% margins and the price of an SSD is directly related to the cost of Flash. Owning the controller IP is key in maintaining solid margins.Enterprise drives will drive flash demand which will lead to economies of scale that result in cheaper Flash prices and consequently cheaper consumer SSD's.

I do trust it with my main workload - database and web server in this case, but of course it is still backed up to mirrored hard drives nightly, just in case.
I'd have no qualms deploying a Z-Drive R4 in one of our HPC clusters, but it'd be an RM88 model with capacitors, and I'd still run the nightly rsync to a large RAID unit. Now if someone would finally signal they want to spend another $100k on a cluster, and I'll spec a nice SSD solution for primary storage.

is it bootable? can it b used 4 a desktop too?
