Seagate Expands Nytro Enterprise SSD Family with 2TB M.2 XM1440

As Flash Memory Summit 2016 approaches, many major players in the SSD market are starting to announce new products. A year after introducing the Nytro XM1440 enterprise M.2 PCIe SSD, Seagate is expanding the lineup with a 2TB option. The XM1440 M.2 and XF1440 2.5" U.2 SSDs are based on the combination of Marvell's 88SS1093 PCIe 3.0 NVMe controller and Micron MLC NAND. The products are a result of a collaboration between Micron and Seagate, and are sold by Micron as the 7100 series. The 2.5" version has had a 2TB-class capacity option from the start, but the new XM1440 2TB is the first of its kind. The higher drive capacity is achieved through denser NAND packaging rather than from switching to higher-capacity 3D NAND dies.
The XM1440 and XF1440 are available in either a capacity-optimized configuration intended for read-intensive workloads and rated for 0.3 drive writes per day, or in an endurance-optimized configuration for mixed workloads and rated for 3 drive writes per day. The latter sacrifices some usable capacity for increased overprovisioning and higher random write speeds, but otherwise they are the same drive. The 2TB XM1440 M.2 will unsurprisingly be one of the capacity-optimized variants, with similar specifications to the 1920GB XF1440 2.5" U.2 SSD.
| Seagate Nytro XF1440 and XM1440 | ||||
| Drive | Endurance Optimized | Capacity Optimized | ||
| Usable capacity | 400 GB, 800 GB, 1600 GB (XF1440 only) | 480 GB, 960 GB, 1920 GB | ||
| Interface | PCIe 3.0 x4 2.5" U.2 (XF1440) PCIe 3.0 x4 M.2 22110 (XM1440) |
|||
| Sequential read | up to 2500 MB/s | |||
| Sequential write | up to 900 MB/s | |||
| Random read IOPS | up to 240K | |||
| Random write IOPS | up to 40K | up to 15K | ||
| Write endurance | 3 DWPD | 0.3 DWPD | ||
| Warranty | 5 years | |||
| Peak power | 12.5 W (XF1440), 8.25 W (XM1440) | |||
| Average read/write power | 9 W (XF1440), 7W (XM1440) | |||
Seagate is also introducing a PCIe add-in card counterpart to the XM1440 and XF1440 as the Nytro XP7102. Based on the same controller and NAND, the XP7102's model number appears to mark it as the entry-level option in a new XP7000 generation to replace the XP6000 series products that were multi-controller solutions with an on-board RAID controller. The Nytro XP7102 targets only the endurance-optimized mixed workload segment with 800GB and 1600GB as the only two capacity options, and has similar specifications to its XF1440 equivalents.
The 2TB XM1440 M.2 will be available in November 2016 and the Nytro XP7102 PCIe add-in card is already available.

Looks like plenty of Power Loss Protection capacitors too.Is that AIC x8 or x4?
DanNeely - Tuesday, July 26, 2016 - link
x8. In x4 the long segment of the connector is only about 2x as big as the short segment.bill.rookard - Tuesday, July 26, 2016 - link
Are you sure about that? Zooming on the picture it specifically says 'PCI Express x4 Gen 3'... :-/evilspoons - Tuesday, July 26, 2016 - link
I was about to say the same, but noticed you beat me to it.It's possible they put the x8 slot in to prevent damage (more physical support) but it's only electrically an x4 device.

Yeah this is exactly it. Mechanical x8, but electrically x4 -- infact if you zoom into the pic you can see that the signal pairs on the last 4 lanes are not connected to anything -- only the grounds connect to the ground plane. Also you can see the 4 lane pairs running up the board from the first 4 lanes in the connector.DanNeely - Tuesday, July 26, 2016 - link
It's a definite mechanical x8. Compare the length of the connector to a physical x4 slot (top position on the board):https://en.wikipedia.org/wiki/File:PCIExpress.jpg
or a physical x4 card:

or the amount of a mechanical x16 electrical x8 connector that has pins on it:

If it's only x4 electrically I'll admit to being puzzled about contacts for lanes 5-8 being plated even if they only wanted the longer connector for enhanced mechanical stability.

You can also count the number of shorter sense (PRSNT2#) pins... the first denotes x1, second x4, third x8, fourth x16. I'm not entirely sure whether it's the motherboard or card that uses pin1a (PRSNT1#) on the opposite side connected with the furthest back of the PRSNT2# pins to figure out how many electrical lanes to utilize, but it's how either the card or motherboard figures out how big of a card or how big of a slot they're mated to.Derek712 - Wednesday, July 27, 2016 - link
Those write IOPS are really low. I hope their price is competitive or I'll just settle for the 960 Pro when it comes out.Laststop311 - Saturday, July 30, 2016 - link
that 2TB m2 drive is looking so nice. Perfect size to eliminate all sata cabling in builds now.
