Samsung Unveils V-NAND High Performance SSDs, Fast NVMe Card At 5.5GB Per Second
MojoKid writes: Sometimes it's the enterprise sector that gets dibs on the coolest technology, and so it goes with a trio of TCO-optimized, high-performance solid state drives from Samsung that were just announced, all three of which are based on three-dimensional (3D) Vertical NAND (V-NAND) flash memory technology. The fastest of bunch can read data at up to 5,500 megabytes per second. That's the rated sequential read speed of Samsung's PM1725, a half-height, half-length (HHHL) PCIe card-type NVMe SSD. Other rated specs include a random read speed of up to 1,000,000 IOPS, random write performance of up to 120,000 IOPS, and sequential writes topping out at 1,800MB/s. The PM1725 comes in just two beastly storage capacities, 3.2TB and 6.4TB, the latter of which is rated to handle five drive writes per day (32TB) for five years. Samsung also introduced two other 3D V-NAND products, the PM1633 and PM953. The PM1633 is a 2.5-inch 12Gb/s SAS SSD that will be offered in 480GB, 960GB, 1.92TB, and 3.84TB capacities. As for the PM953, it's an update to the SM951 and is available in M.2 and 2.5-inch form factors at capacities up to 1.92TB.
Even I have my limits.
Last SSD I bought was only 7200 RPM, and was disappointing.
All joking aside, these drives have their uses, and not just the enterprise. The SAS SSD models definitely will be a no-brainer because of SAN demand.
The PCIe card will come in handy if you are using ESXi, because the hypervisor can use the SSD as swap. Yes, it is definitely slower than RAM... but not devastatingly so as it would be if using a mechanical HDD. So, it will help with overcommits and soften the blow when a user's 2GB VM request winds up being a 128GB appliance for video processing.
I do wonder if the PCIe card is bootable or not. If it is bootable, it would be useful for a desktop/workstation that doesn't have a M.2 slot.
> Impressive stuff, though it's the sequential read speed that's the real head turner here. At 5,500MB/s (5.5GB/s), Samsung says a user can save a 5GB video file in less than three seconds.
checks URL, yep more quality hothardware journalism
It writes at 1.8 GB/s, so the math is correct. The English is bad because they mentioned the read speed in between two mentions of the write speed.
To cost more than what I've spent on my last 3 computers combined.
Symmetric read/write at 5.5GB/s would be better, but as it is, it would still be quite an upgrade from my current RAID0 array. I'm only getting ~700-800MB/s sequential with four 10krpm SAS drives right now. Of course one of these SSDs will probably cost 5-10x more than a set of those spinning drives. So price/performance really isn't that great of a deal.

This article states:
"As for the PM953, it's an update to the SM951 and is available in M.2 and 2.5-inch form factors at capacities up to 1.92TB"
There's NO WAY that it's an upgrade to the SM951. The SM951 has been out for only FOUR months now and has only been available to OEMs. Mainstream release to consumers are slated to occur later this year.

$306. I don't know if that is wholesale or what.
Because gamers are fucking l33333t like, shit, bro. Derp.
And you thought Kim Jung Little is all bluster. Seagate? Dump it NOW!
" the latter of which is rated to handle five drive writes per day (32TB) for five years...." ... with a failure rate of what 5%, 10%, 50%, 80%?
I mean they didn't test a big batch of them for 5 years, since they've only just made them, they tested a batch and some failed after 3 months or 6 months and from that they extrapolated an acceptable fail rate they were prepared to replace for free under warranty.
Which means a lot of them failed in the test!
> 6.4TB, the latter of which is rated to handle five drive writes per day (32TB) for five years
~10K write cycles. This sounds rather good.
Who logs in to gdm? Not I, said the duck.
Slapping together a bare bones system costs a lot less than buying enterprise storage. I've done that recently, and spent about $1200, like you said. I bought a use raid card on eBay because the card cost almost $1200 new. Then you get a proper chassis with reliable, hotswappable cooling for all those drives running 24/7, redundant power supplies, a backplane, etc. About the only way you're going to get enterprise grade raid for $1200 is to buy used, which I often do.
"The fastest of bunch"
I remember just ten years ago RAM, yeah RAM, was slower than these drives. Time flies!
But do they properly support the TRIM command?

QUOTING THE SHOW "The 6 Million Dollar Man" (for those of you old enough to know that show that is):
"We can make him BETTER than he was before - Better, Faster, Stronger..."
(... & It's far better + more useful news than "Gay Marriage" carrots tossed out there, that are intended to distract you from REAL issues out there, or good news like this...)
That's what this does for SSD, the "wave of the future" (what I've been using @ HOME no less, ones based on "REAL RAM", not flash, since oh, 2000 or thereabouts...) - & THAT future?
IS, truly, NOW!

P.S.=> I wonder (since I haven't read the article yet) - IS IT BASED ON/INTENDED for Pci-Ex architecture too? That is a HUGE help to SSD's, overcoming bus speed limitations... apk
