Because SSDs in an enterprise environment are assumed to be active 24x7, idle power consumption doesn't receive the emphasis that it might in a desktop or notebook. Even so, it's interesting that Toshiba's enterprise SSD is the only drive that draws more than 1 W without doing anything at all.

When it's busy crunching 4 KB random access, Toshiba's MK4001GRZB uses more than two times the power of Micron's P300. Both drives employ SLC NAND, so the difference isn't necessarily attributable to Toshiba's choice in memory technology.


Switching to sequential accesses, the MK4001GRZB consumes substantially more power than all of the other tested SSDs.
If you flip back through the performance analysis, you find that, at a queue depth of eight, Intel's SSD 520 is roughly as fast as the Toshiba drive in this very same workload. Compare that to our power numbers and you find that the SandForce-based desktop drive uses a lot less power to achieve similar performance, making it a more efficient solution in read-heavy workloads.
We see a similar situation evolve in sequential write testing. The P300 outperforms the MK4001GRZB by roughly 19%, yet Toshiba's drive consumes almost 42% more power.


Larger block sizes don’t affect power consumption by much. At a queue depth of eight, 128 KB and 2 MB performance is roughly the same, which means efficiency is, too.

...fullish of cash? Definitely. Foolish? Probably not.
You've clearly not understood the purpose of this article. Stick to commenting the desktop drive reviews in the future, please.
Thank you for this review, and especially your estimations on the endurance of the drive. It's something that's damn near impossible for us IT professionals to get accurate estimations of in the real world. For some reason, bosses tend to want the expensive hardware to be put to use instead of being thoroughly tested.
More of these types of articles please! :]
Perhaps the Enterprise SSD Fairy will bring you a Hitatchi UltraStar with Intel's 6gbps controller. I'd be eager to see how it compares.
There is no substitute for SLC though.

damn the english language.....there are way to many words that sound alike

Even when the INTEL SSD already has an endurance longer than your refresh cycle for your tech stack?
"Back in my days storage drives used to have moving parts. Now its all solid state."
Unlike super-sized enterprise which I am not, the cost/benefit calculations would be difficult for myself. I know firsthand the money that i.e. financial institutions push into their data centers, and for those folks $7K isn't out of the question.
Interesting SSD and if the prices come down and warranty extended then IMO it would be something to consider and compare against Intel's products.
I was not disappointed.
I refer you to the ~$20,000 1.2TB fusion-io SSD's.
but wow... $7000...
I go with 10 of 128GB SSD....
Hell I'll gladly pay that much because drives like this save money in the long run. They are cheaper and much easier to set up and maintain vs hundred of mechanical drives in a raid setup. In power alone over the live of the drive vs mechanical drives adds up. So $7k isn't that bad and this isn't the most expensive SSD that I have seen.
Throw 50TB daily writes on that Intel SDD array of yours and it will last you only 3 months until full failure.
"Hey uh, our entire rack of $50 SSDs simply died on us, along with all of our business files."
Throw 3 Intel MLC 480 GB SSD's in RAID-5 (1k each), make an agressive overprovisioning...and they will both last MUCH longer and also run circles to this expensive piece of hardware being reviewed.
Heck, it's pretty much touching Fusion-IO pricing without even coming close on speed.
This will only work for people needing plug & play replacement for their SAS drives AND with very deep pockets. Since i suspect the replacement should be made in batches...it will be VERY expensive.
Anyone else with brains can find a lot of cheaper, faster AND more reliable solutions.
I'd wait for a Velodrive, raid a couple of them and just have regular backups on a storage with regular HDD's (that is, read GB/s from a couple SSD's...write GB/s sequentially to a storage).
I do understand though that there are out there companies that can't risk innovation and smart choices and have to recur to handwritten promises and warranties of the big guys.
Reason why buying a Dell costs a hell lot more than building it yourself.
Reason why building your own storage is a fraction of the price of an EMC solution.
And so on...
For $7000 that is the first thing I would have done Andrew.
"Why are they called drives, granpa?"
