Seagate showed off some impressive Solid State Storage at Flash Memory Summit 2016.

DSC02135.jpg

First up is the Nytro XM1440. This is a 2TB M.2 22110 SSD complete with enterprise firmware and power loss protection. Nice little package, but what's it for?

DSC02136.jpg

..well if you have 60 of them, you can put them into this impressive 1U chassis. This is Facebook's Lightning chassis (discussed yesterday). With Seagate's 2TB parts, this makes for 120TB of flash in a 1U footprint. Great for hyperscale datacenters.

Now onto what you came to see:

DSC02123.jpg

This is the 'Seagate 60TB SAS SSD'. It really doesn't need a unique name because that capacity takes care of that for us! This is a 3.5" form factor SAS 12Gbit beast of a drive.

DSC02134.jpg

They pulled this density off with a few tricks which I'll walk through. First was the stacking of three PCBs with flash packages on both sides. 80 packages in total.

DSC02124.jpg

Next up is Seagate's ONFi fan-out ASIC. This is required because you can only have so many devices connected to a single channel / bus of a given SSD controller. The ASIC acts as a switch for data between the controller and flash dies.

DSC02125.jpg

With so much flash present, we could use a bit of fault tolerance. You may recall RAISE from SandForce (who Seagate now owns). This is effectively RAID for flash dies, enabling greater resistance to individual errors across the array.

DSC02129.jpg

Finally we have the specs. With a dual 12 Gbit SAS inteface, the 60TB SAS SSD can handle 1.5 GB/s reads, 1.0 GB/s writes, and offers 150,000 IOPS at 4KB QD32 random (SAS tops out at QD32). The idea behind drives like these is to cram as much storage into the smallest space possible, and this is certainly a step in the right direction.

DSC02138.jpg

We also saw the XP7200 add-in card. I found this one interesting as it is a PCIe 3.0 x16 card with four M.2 PCIe 3.0 x4 SSDs installed, but *without* a PLX switch to link them to the host system. This is possible only in server systems supporting PCIe Bifurcation, where the host can recognize that certain sets of lanes are linked to individual components.

Just because you are on the road there is no reason to subject yourself to HDD speeds when transferring files.  Not only will an SSD be quieter and more resilient but the USB 3.1 Gen 1 Type C port theoretically offers up to 450MB/s transfer speeds.  This particular 2TB portable SSD uses the same MGX controller as the 850 EVO, the NAND is Samsung's 48-layer TLC V-NAND.  The Tech Report previously tried out the T1 model so their expectations were that this drive would improve performance in addition to offering larger sizes of drive.  Does it live up to expectations?  Find out in their full review.

Al just reminded yours truly we posted a review of the T3 back in February.

FMS 2016: Facebook Talks WORM QLC NAND Flash, Benchmarks XPoint

Subject: Storage | August 9, 2016 - 05:59 PM |

At their FMS 2016 Keynote, Facebook gave us some details on the various storage technologies that fuel their massive operation:

DSC02009.jpg

In the four corners above, they covered the full spectrum of storing bits. From NVMe to Lightning (huge racks of flash (JBOF)), to AVA (quad M.2 22110 NVMe SSDs), to the new kid on the block, WORM storage. WORM stands for Write Once Read Many, and as you might imagine, Facebook has lots of archival data that they would like to be able to read quickly, so this sort of storage fits the bill nicely. How do you pull off massive capacity in flash devices? QLC. Forget MLC or TLC, QLC stores four bits per cell, meaning there are 16 individual voltage states for each cell. This requires extremely precise writing techniques and reads must appropriately compensate for cell drift over time, and while this was a near impossibility with planar NAND, 3D NAND has more volume to store those electrons. This means one can trade the endurance gains of 3D NAND for higher bit density, ultimately enabling SSDs upwards of ~100TB in capacity. The catch is that they are rated at only ~150 write cycles. This is fine for archival storage requiring WORM workloads, and you still maintain NAND speeds when it comes to reading that data later on, meaning that decade old Facebook post will appear in your browser just as quickly as the one you posted ten minutes ago.

DSC02028.jpg

Next up was a look at some preliminary Intel Optane SSD results using RocksDB. Compared to a P3600, the prototype Optane part offers impressive gains in Facebook's real-world workload. Throughput jumped by 3x, and latency reduced to 1/10th of its previous value. These are impressive gains given this fairly heavy mixed workload.

FMS 2016: Micron Keynote Teases XPoint (QuantX) Real-World Performance

Subject: Storage | August 9, 2016 - 03:33 PM |
Tagged: XPoint, QuantX, nand, micron

Micron just completed their keynote address at Flash Memory Summit, and as part of the presentation, we saw our first look at some raw scaled Queue Depth IOPS performance figures from devices utilizing XPoint memory:

U.2.jpg

These are the performance figures from an U.2 device with a PCIe 3.0 x4 link. Note the outstanding ramp up to full saturation of the bus at a QD of only 4. Slower flash devices require much more parallelism and a deeper queue to achieve sufficient IOPS throughput to saturate that same bus. That 'slow' device on the bottom there, I'm pretty certain, is Micron's own 9100 MAX, which was the fastest thing we had tested to date, and it's being just walked all over by this new XPoint prototype!

Ok, so that's damn fast, but what if you had an add in card with PCIe 3.0 x8?

HHHL.jpg

Ok, now that's just insane! While the queue had to climb to ~8 to reach these figures, that's 1.8 MILLION IOPS from a single HHHL add in card. That's greater than 7 GB/s worth of 4KB random performance!

latency.jpg

In addition to the crazy throughput and IOPS figures, we also see latencies running at 1/10th that of flash-based NVMe devices.

x10.jpg

..so it appears that while the cell-level performance of XPoint boasts 1000x improvements over flash, once you implement it into an actual solution that must operate within the bounds of current systems (NVMe and PCIe 3.0), we currently get only a 10x improvement over NAND flash. Given how fast NAND already is, 10x is no small improvement, and XPoint still opens the door for further improvement as the technology and implementations mature over time.

The UFS standard aims to bring us lightning fast microSD cards that perform on-par with SATA SSDs. Samsung introduced theirs earlier this month, and now Micron has announced their solution:

Mobile 3D NAND UFS with specs and logo.jpg

As you can see, UFS is not just for SD cards. These are going to be able to replace embedded memory in mobile devices, displacing the horror that is eMMC with something way faster. These devices are smaller than a penny, with a die size of just over 60 mm squared and boast a 32GB capacity.

UFS.png

One version of the UFS 2.1 devices also contains Micron's first packaged offering of LPDDR4X. This low power RAM offers an additional 20% power savings over existing LPDDR4.

Also up is an overdue branding of Micron's XPoint (spoken 'cross-point') products:

MIcron_QuantX_Logo_Black.Gray_60%.png

QuantX will be the official branding of Micron products using XPoint technology. This move is similar to the one Intel made at IDF 2015, where they dubbed their solutions with the Optane moniker.

More to follow from FMS 2016. A few little birdies told me there will be some good stuff presented this morning (PST), so keep an eye out, folks!

Press blast for Micron's UFS goodness appears after the break.

Introduction and Specifications

Introduction

Barracuda is a name we have not heard in a good while from Seagate. Last seen on their 3TB desktop drive, it appears they thought it was time for a comeback. The company is revamping their product lines, along with launching a full round of 10TB Helium-filled offerings that cover just about anything you might need:

seagate HDD line.png

Starting from the center, IronWolf is their NAS drive, optimized for arrays as large as 8 disks. To the right is their surveillance drive offering, the SkyHawk. These are essentially NAS units with custom firmware optimized for multiple stream recording. Not mentioned above is the FireCuda, which is a rebrand of their Desktop SSHD. Those are not He-filled (yet) as their max capacity is not high enough to warrant it. We will be looking at those first two models in future pieces, but the subject of today’s review is the BarraCuda line. The base 3.5” BarraCuda line only goes to 4TB, but the BarraCuda Pro expands upon those capacities, including 6TB, 8TB, and 10TB models. The subject of today’s review is the 10TB BarraCuda Pro.

Samsung PM1633a: 15.36TB SSD for $10,000 USD

Subject: Storage | August 1, 2016 - 11:03 PM |
Tagged: ssd, Samsung, enterprise ssd

Allyn first mentioned this device last year, but they're apparently now shipping for a whopping $10,000 USD. To refresh, the PM1633a is an SSD from Samsung that packs 15.36TB into a 2.5-inch form factor. According to Samsung, it does this by stacking 16 dies, each containing 48 layers of flash cells, into a 512GB package. It's unclear how many packages are installed in the device, because we don't know how much over-provisioning Samsung provides, but the advertised capacity equates to exactly 30 packages. Update @ 11:30pm: Turns out I was staring right at it in the old press release. The drive has 32 packages, so 16384 GB, once you account for over-provisioning.

Down at CDW, they are selling them for $10,311.99 USD with the option to lease for $321.73 / month. That's only 2.1c/GB... per month... for probably three whole years. No Ryan, that doesn't count. The warranty period doesn't seem to be listed, but Samsung will cover up to 15.36TB per day in writes. I mean, we knew it would be expensive, given its size and performance. At least it's only ~65c/GB.

Even the M.2 form-factor version of the SSD includes a heatsink, which Plextor warns creates incompatibility with notebooks as the M8PeG is 4.79 mm in height with the heatsink in place.

Specifications for the drives are as follows:

  Plextor M8PeG Plextor M8PeY
Controller Marvell 88SS1093 (8-Channel)
DRAM 512MB LPDDR3 (1024MB variant)
Capacity 128 GB, 256 GB, 512 GB
NAND Toshiba 15nm Toggle 2.0 MLC
Form Factor M.2 (80 mm) PCIe card (HH, HL)
Interface PCIe 3.0 x4
Warranty 5 years

So what did Computer Base have to report with their hands-on preview of the new drive? Here's their CrystalDiskMark result:
