    Toshiba Announces Three New NVMe SSD Families

    On the eve of Flash Memory Summit (August 11-13), Toshiba has announced a full range of NVMe-based PCIe SSDs using Toshiba controllers and Toshiba MLC flash.

    Toshiba NVMe Drive Families
    Drive Series PX04P XG3 BG1
    Form Factors and Interface PCIe 3.0 x4 HHHL /
    2.5” U.2
    PCIe 3.1 x4 M.2 2280 / 2.5” SATA Express M.2 2230 /
    16mm*20mm soldered module "M.2 1620"
    Capacities 800 GB, 1600 GB, 3200 GB Up to 1024GB Up to 256 GB
    QSBC Error Correction Yes Yes No
    TCG Pyrite Security No Yes Yes
    Sequential Read 3100 MB/s ? ?
    Sequential Write 2350 MB/s ? ?
    4kB Random Read IOPS 660k ? ?
    4kB Random Write IOPS 185k ? ?

    For the enterprise market, the PX04P series complements the SAS-based PX04S drives announced last week. The PX04P is available as a 2.5” drive with a U.2 (SFF-8639) connector, or as a PCIe expansion card. In either case, the drive supports four lanes of PCIe 3.0 and can make good use of that bandwidth to offer up to 3.1 GB/s sequential read speeds. With an endurance rating of 10 drive writes per day it is intended for relatively write-heavy workloads.

    For the high-performance client market, the XG3 is available in the M.2 2280 form factor using four lanes of PCIe 3.1, or as a 2.5” drive using the two-lane SATA Express connector. If these drives make it in to the retail channel, it means that consumers whose motherboards have a SATA Express connector but no M.2 slot will finally have an easy way to get in on the PCIe storage revolution.

    For tablets and ultra-thin laptops, the BG1 is optimized for low power in very small packages. It comes as either an M.2 2230 card or a soldered-down module measuring 16mm by 20mm. The BG1's maximum capacity is only 256 GB, and given the power and size constraints it is probably not using a 4-lane PCIe connection.

    The two client drive families implement support for the Trusted Computing Group Pyrite standard, a subset of TCG Opal that includes features necessary for things like secure boot but does not include encryption.

    NVIDIA Announces Quadro M5000 & M4000 Video Cards, DesignWorks Software Suite

    Back in March at GTC 2015, NVIDIA announced the first member and flagship of their Maxwell 2 generation of Quadro cards, the Quadro M6000. Packing a fully-enabled GM200 GPU and 12GB of RAM, M6000 signaled an interesting shift from NVIDIA on the high-end of Quadro, with the company shipping what amounted to a “pure” graphics card as opposed to a jack-of-all-trades type card as they typically do at the high-end.

    Meanwhile, although the M6000 was the first Maxwell 2 based Quadro card to launch, it was not the first Maxwell 2 GPU to launch. NVIDIA has launched GM204 and GM206 late last year and early this year respectively, and of course Maxwell 1 ended up in the Quadro K2200 and a couple of other cards. As a result we have been expecting NVIDIA to refresh the rest of the Quadro lineup with Maxwell 2 after the release of the M6000, and this week at SIGGRAPH NVIDIA is doing just that with the release of the Quadro M5000 and Quadro M4000.

    4Kp60 Displays Supported 4 4 2 2

    We’ll start things off with the Quadro M5000. While NVIDIA has not announced the GPU for these new products, we believe the M5000 to be based on GM204, given the CUDA core and memory bus configuration. By those standards M5000 would be a fully enabled GM204 card, featuring all 2048 CUDA cores and the full 256-bit memory bus, essentially making this the Quadro version of the GeForce GTX 980.

    Curiously, the M5000 features DRAM soft ECC support, allowing for error correction on the DRAM. Previous 5000-series Quadro cards have also included this feature, but at a GPU level NVIDIA typically reserves this feature for their highest-tier GPUs. With that said, as it’s software based and we’ve seen NVIDIA enable it in a Kepler-based GK104 product before (Tesla K10), for the moment we believe that they have gone ahead and enabled it for this GM204 product, rather than outfitting the card with GM200.

    Paired up with the GM204 is 8GB of GDDR5 clocked at a slightly more conservative 6.6GHz. Based on these specifications it’s not clear whether NVIDIA is using 16 4Gbit chips or 8 8Gbit chips, as the latter are now available though still fairly rare (M6000 by comparison used 24 4Gbit chips). In any case this is the same amount of RAM as the previous Quadro K5200 shipped with, indicating that NVIDIA is targeting the same market segment as before.

    As for GPU clockspeeds, as is usually the case NVIDIA has not published specific clockspeeds, but in their press materials they have the card’s FP32 performance listed at 4.3 TFLOPs. This would put the maximum GPU clockspeeds at around 1.05GHz, though as this is a GPU boost product we don’t know the base clockspeeds at this time.

    NVIDIA has also published the power information for this card, and like its Kepler-based predecessor it’s a 150W card. A 150W TDP allows M5000 to more easily work in lower power workstations where only a single 6-pin PCIe power connection is available, and is actually a bit lower power than comparable desktop GeForce products. Though as a result we expect that shipping clockspeeds are below 1GHz.

    Meanwhile NVIDIA has typically gone with dual-slot blowers on their 150W Quadro cards, and M5000 will be no exception. The card is shipping with what appears to be a new blower and shroud design – and one I suspect is all plastic like the Quadro K5200’s – mimicking the original metal shroud of the M6000. At any rate this is a full size card, meaning it measures 10.5” long like NVIDIA’s other high-end cards.

    Finally, much like the M6000, the overall importance of a Maxwell release is two-fold for NVIDIA. First and foremost of course are the performance improvements from Maxwell, which achieves much better performance per CUDA core and much better energy efficiency than the preceding Kepler parts, so M5000 should achieve even better real-world performance than its already substantial on-paper specifications indicate. However the other significant benefit here is that the switch to Maxwell means that the Quadro cards gain Maxwell’s newer display controller and NVENC blocks, allowing the M5000 to drive four 4K displays – twice as many as K5200 – and real-time HEVC encoding.

    M4000

    Also launching today and below the M5000 is the M4000. This appears to be another GM204 design, forgoing some of GM204’s CUDA cores in exchange for lower costs, performance, and power consumption. Like the M5000 we don’t have the clockspeed information for the card, but we do know it features 1664 active CUDA cores, making it analogous to the GeForce GTX 970. Also like the M5000 this features 8GB of VRAM – twice as much as the K4200 – this time clocked at 6GHz, however without the soft ECC support of the higher-end Quadro cards.

    Compared to the M5000 the TDP on the M4000 is down by 30W to 120W. The previous Quadro K4200 was a 105W card, so power consumption is up slightly, but in turn the M4000 features the Maxwell family improvements and more CUDA cores than the K4200. The card is rated for 2.6 TFLOPs of FP32 performance, which puts the maximum clockspeed at around 780MHz, so we expect that performance will be greatly improved over the K4200.

    Meanwhile like past Quadro 4000-series cards, the M4000 is a single slot design. To the best of our knowledge this is a new PCB design for NVIDIA, and taking advantage of the lower power requirements brings the length of the card down to 9.5”. In order to get everything down a single slot NVIDIA has done away with the DVI port – a first for the 4000 series – making M4000 a 4x DisplayPort design. As we mentioned with M5000, the Maxwel display controller improves 4K support to allow 4 such displays off of a single card, and this is a scenario NVIDIA is clearly looking to enable with the M4000.

    Finally, as is usually the case for NVIDIA, the company is not publishing any official prices for these cards, leaving pricing up to their partners and vendors. That said, at this point we expect pricing to be similar to the Quadro K5200 and K4200, which would put street prices on the cards at around $2000 and $1000 for the M5000 and M4000 respectively.

    NVIDIA Launches DesignWorks

    Along with the release of their latest Quadro cards, NVIDIA is also announcing a new software suite at SIGGRAPH: DesignWorks. The latest Works project, DesignWorks, is partially a collection of new software and partially a branding exercise for the company. Following in the footsteps of GameWorks for game development, NVIDIA is collecting most of their tools and libraries for professional graphics development under the DesignWorks brand, and going forward will be releasing new tools under this brand as well.

    Along with collecting previous disparate tools like Iray and OptiX, the announcement of DesignWorks also marks the introduction of some new tools for NVIDIA. Of particular note here is NVIDIA vMaterials, a library of digitized, real world materials for use in applications that can interface with NVIDIA’s Material Design Language, MDL. Also premiering with DesignWorks is a version of NVIDIA’s VR technology optimized specifically for professional use, aptly named DesignWorks VR.

    Meanwhile NVIDIA’s technology focus for the DesignWorks launch is on Physically Based Rendering (PBR), a realistic rendering technique the company has been promoting for much of the last year now. PBR is very GPU intensive – always a plus for someone in the business of selling GPUs – but in turn is designed to offer more photo-realistic results (but not necessarily more accurate results) by focusing on simulating the properties of the materials of the surrounding world itself. This focus on PBR goes hand-in-hand with the NVIDIA vMaterials announcement in particular, as a big part of enabling PBR is creating the material representations themselves.

    Finally, as part of their PBR push over the past year, NVIDIA has been showing off various images under the Real or Rendered tagline. For SIGGRAPH the company has put together an admittedly impressive render of a DeWalt drill, which is close to the real thing, though not identical to it.

    StarTech.com 8-bay USB 3.0 / eSATA Removable Hard Drive Enclosure Review

    Network Attached Storage (NAS) devices have become quite popular over the last five years or so, but Direct Attached Storage (DAS) units were the go-to devices for consumers looking to store large amounts of data before that. The interfaces for these DAS units have evolved from USB 2.0 and Firewire to eSATA and nowadays, USB 3.x and Thunderbolt. What sort of performance numbers and features can we expect in a modern multi-bay DAS unit? What are the use-cases enabled by them in the modern computing ecosystem? Our review of the StarTech.com S358BU33ERM 8-bay USB 3.0 / eSATA hard drive enclosure provides some answers.

    Seagate Introduces New Nytro PCIe SSDs: XP6500 & XF/XM1440

    After acquiring SSD controller designer SandForce, LSI took the quick route towards creating high-performance PCIe SSDs by putting multiple SandForce controllers and an LSI RAID controller on a single expansion card, branding the resulting product as the Nytro. This Nytro product line was transferred to Seagate along with the SandForce division in May 2014, and it's now getting both a refresh and a major expansion.

    The new Nytro XP6500 succeeds the Nytro XP6302 and offers improved write latency and improved write endurance. Write throughput suffers slightly, but the XP6302's original performance specifications were inflated by testing at 28% over-provisioning rather than the default of 17% that is implied by the listed capacities. Meanwhile the XP6500 4TB model is listed as optimized for 8kB rather than 4kB random accesses, so its IOPS numbers aren't directly comparable to the others.

    Seagate Nytro XP6000 Series
    Drive XP6500 4TB XP6500 1.5TB XP6302
    Usable capacity 3.4TB 1.3TB 1.3TB, 1.75TB, 3.5TB
    Interface PCIe 3.0 x8
    Sequential read 4 GB/s
    Sequential write 2.2 GB/s 1.5 GB/s 2.3 GB/s
    Random read IOPS 275K (8KB) 300K (4KB) 296K (4KB)
    Random write IOPS 85K (8KB) 100K (4KB) 148K (4KB)
    Write latency 14µs 33µs
    Write endurance 20 PB 8 PB 6.6-11.7 PB
    Required airflow 550 LFM 300 LFM

    Peak power consumption isn't listed but is likely significantly increased over the XP6302's 39W, based on the increase in required airflow from 300LFM to 550LFM for the same operating temperature range. The Nytro XP6500 supports a supercapacitor bank to protect data in its large (2-4GB) DRAM cache. The XP6500 is available either as a full-height expansion card with built-in supercapacitors, or as a half-height card with an optional tethered supercapacitor module. Seagate has announced immediate availability of the Nytro XP6500.

    Expanding the Nytro brand into new territory are the XF1440 and XM1440 NVMe drives, in 2.5" U.2 (SFF-8639) and M.2 22110 form factors respectively. They're split in to two tiers: “Endurance Optimized” (3 drive writes per day) and “Capacity Optimized” (0.3 DWPD).

    Seagate Nytro XF1440
    Drive Endurance Optimized Capacity Optimized
    Usable capacity 400 GB, 800 GB, 1600 GB 480 GB, 960 GB, 1800 GB
    Interface PCIe 3.0 x4 SFF-8639
    Sequential read 2700 MB/s
    Sequential write 600-1200 MB/s
    Random read IOPS 200K
    Random write IOPS 34K 3K–7K
    Write endurance 3 DWPD 0.3 DWPD
    Warranty 5 years
    Peak power 12.5 W
    Average read/write power 9 W

    Performance specifications for the Nytro XM1440 weren't available, and we aren't assuming that they will be the same as for the Nytro XF1440. The XF is listed as using eMLC (Enterprise MLC) but the XM is using MLC+, a term often used to refer to higher-binned consumer-grade MLC. Maximum power consumption is significantly lower for the XM, and the XM will be released later (early 2016, when the XF1440 will ship at the end of October), which suggests that there may also be controller differences.

    Seagate Nytro XM1440
    Drive Endurance Optimized Capacity Optimized
    Usable capacity 400 GB, 800 GB 480 GB, 960 GB
    Interface M.2 PCIe 3.0 x4
    Write endurance 3 DWPD 0.3 DWPD

    Peak power 8.25 W
    Average read/write power 7 W

    SanDisk Announces Second Generation CloudSpeed Ultra SATA Enterprise SSD

    At Flash Memory Summit today SanDisk announced the second generation of their CloudSpeed Ultra enterprise drive. This is the sibling to the gen. 2 CloudSpeed Eco that was announced in June.

    As with the Eco gen. 2, the Ultra gen. 2 transitions from 19nm to 15nm MLC and brings a reduced endurance rating but increased performance. The Ultra model continues to be geared for mixed read/write workloads while the Eco is for more read-intensive uses.

    4kB Random Write IOPS 32k 14k 30k
    Endurance Rating 1.8 DWPD 0.6 DWPD 3 DWPD

    SanDisk is already supplying the CloudSpeed Ultra gen. 2 to several major customers for large-scale deployments and it will be more broadly available later in 2015, where it will be competing against drives like Samsung's SM863 and Intel's DC S3610. Pricing will be under $1/GB, but we don't know by how much. It probably won't be undercut by Intel's DC S3610, but to be competitive it will need to be down near Samsung's $0.66/GB for the SM863.
