Pricing And Accessories
The SM951s come from Samsung's SSI group, which sells to OEM customers. These products are normally not available to end-users. But demand for the company's SSDs compelled Samsung to let a limited supply bleed through to a few resellers large enough to have accounts with key distributors. Vendors spec their own warranty terms, conditions, pricing and even packaging.
We get all of our SSI products from RamCity, an Australian-based company. RamCity sells direct and also has an Amazon account where products are stored and shipped from North America. The SM951s are hot items, so prices are subject to change based on availability. The Australian site advertises in Australian Dollars with Australian VAT taxes that do not apply to orders coming from other countries.
It'd be a shame to see this eventually end up as a 2 horse race intel vs. samsung.
Here's to hoping marvell and others step up this year.
I'm really hoping for that editorial mentioned in this review. It's unbelivable that last mechanical HDD reviewed by Tom's Hardware was 4TB Seagate in July 2013 !! We've since gone to 8TB drives, new technologies, and so on. I know SSDs are future, but there are still millions of old fashioned HDDs sold each year. I still can't afford a 10TB storage build solely from SSDs.
So please, do a proper editorial, include everything from Intel 750 and new SM951 NVMe editions, performance SATA SSDs, lower end SATA SSDs, speedy SATA HDDs, large archival "green" HDDs, etc. Keep in mind that people have diverse needs. I want a relatively large SSD in my desktop, but one I can actually afford (not costing more than either CPU or GPU), I want a speedy yet small SSD for my laptop, and can afford more $/GB here because I don't need a 1TB drive, but I want it to have good performance per watt, and I also want large storage drive(s) for desktop, but we're always looking for good performance per $$$ spent. These are widely different categories, and some haven't been covered by Tom's in years.
Also, when doing the editorial, please keep the charts of "real-world performance" in seconds. It really is a better way to see where to draw the line. If a test lasts 5 minutes and a 1000$ drive shaves 5 seconds over 100$ drive, I don't want to spend extreme $$$$ for those 5 seconds. OK, someone will want to shave even those 5 seconds, but give us info so we can make our buying decisions.
I personaly am planning on building new PC, AND buying a new laptop, and I really want to make an optimal build(s) where I can decide how many GB/TB I'll appoint in SSDs, and how much in storage HDDs. SSD is getting cheaper all the time, but it's still not THAT cheap if your needs are measured in range of 10TB that you can just go buy some blindly.
As for last few SSD reviews, they really paint an interesting picture, and even more so makes me ask some questions like above. If you overlap some charts, and you're not a heavy workstation user, it does seem that any SSD drive will do for 99% of tasks.. and saving some serious money and investing it in other subsystems is probably a wise choice, instead of just going after benchmark numbers. I'm way past the "my benchmark is bigger than yours", and if it isn't translated in performance that you can percieve with our limited human senses - it's simply a number on paper, no more.
Do Z97 motherboards with M.2 slots use Sata or PCI-E?
and, Do video cards installed on a motherboard with an occupied PCI-E M.2 slot operate at x8 bandwidth or at the full x16?
Ultimately, I'd like to move completely away from mechanical storage. But it will be a few years until a 4TB SSD is affordable. Sure, mechanical storage may retain a $/GB edge, but there comes a point when solid state storage is plentiful and large enough that mechanical hard drives will join tape drives as an archive only format that will fade off into computing history as SSDs become large enough to meet most people's needs as both a system and archival drive.
By the way, I've built my own systems for some time and this is the first time I have ever considered waiting for the next great thing to come out. It's so much more difference than the usual increment.
The SM951 uses 4 lanes, the XP941 uses 2.
