Interesting, you're right the IODrive 2 brings MLC much closer to SLC, there's only a 2x performance delta on an IOPS/GB basis (270k 4k random writes vs 140k for 400GB vs 365GB), for the first generation (which I own a number of) the gulf was much wider.

I have never seen a smaller version ssd have a better IOPS number than a larger one.

I have, plenty of times, SLC has better IOPS/GB than MLC and within MLC eMLC has better IOPS/GB than tMLC. So for a given number of dollars the smaller drive will have better performance.

Comment Ted Unangst's article (Score 4, Informative) 304


Ted Unangst wrote a good article called "analysis of openssl freelist reuse"

His analysis:

This bug would have been utterly trivial to detect when introduced had the OpenSSL developers bothered testing with a normal malloc (not even a security focused malloc, just one that frees memory every now and again). Instead, it lay dormant for years until I went looking for a way to disable their Heartbleed accelerating custom allocator.

it's a very good read.

Yes, I've heard of Xen, and I've even run it in production, both Xenserver and Oracle VM flavors, and both sucked horribly. Back when VMWare tried the v.Tax I contemplated switching to KVM using RHEV but Redhat took almost 30 days to even get me access to a RHEV download by which time VMWare had backed off on their pricing.

As to the crack about redundancy and scalability, I've got a better uptime metric than any cloud provider, zero unplanned downtime in the last 5 years (vmotion + svmotion makes replacing both hosts and storage a breeze) thanks to redundant generators, UPS, chillers, and internet connections.
