Intel unveils two new lineups of datacenter SSDs

Along with its Xeon E5-2600 v4 CPUs, Intel took the wraps off two new datacenter SSD lineups today. The SSD DC P3320 and DC P3520 are Intel's first drives to use 3D NAND, while the SSD DC 3600 and DC 3700 are the company's first dual-port SSDs.

The SSD DC P3320 uses a PCIe 3.0 x4 interface and the NVMe protocol. It's meant for read-intensive applications for cloud storage and data analytics, according to Intel. That's borne out by Intel's performance specifications. The 450GB P3320 can perform sequential reads as fast as 1,100 MB/s and random reads at up to 130K IOPS. Those numbers rise to 1,600 MB/s and 365K IOPS in the 2TB version. Sequential write performance is slightly more subdued, at 500 MB/s in the 450GB drive and 1,400 MB/s in the 2TB version. Random writes ring in at just 17K IOPS in the 450GB model, while the 2TB drive manages 22K IOPS.

Intel didn't share many details about the P3520 SSDs today, but the company says those drives will deliver "significant performance and latency improvements over the DC P3320." Intel claims those improvements make the P3520 more suitable for use in storage virtualization and web-hosting enviroments.

Capacity Max sequential (MB/s) Max random (4KB IOps) Form factor
Read Write Read Write
1TB 1,800 940 450K 25K U.2, 2.5"
2TB 2,100 1,500 470K 30K


Intel SSD DC D3700 series
Capacity Max sequential (MB/s) Max random (4KB IOps) Form factor
Read Write Read Write
800GB 1,900 970 450K 65K U.2, 2.5"
1.6TB 2,100 1,500 470K 95K

The SSD D3600 and DC3700 series are meant for companies that demand high performance along with high availability. These dual-port drives are built to work with storage systems in applications like online transaction processing that demand 24/7 accessibility and failover recovery.

According to Intel, high-availability storage architectures require that at least two controllers be able to access the same drive through a multi-path topology so that a controller failure won't cause a service interruption. Intel thinks these drives will be especially appealing to companies already using SAS storage for that purpose, and it also thinks companies moving to all-flash and hybrid-flash storage arrays will want to take a look at these dual-port SSDs.

Both the SSD DC D3600 and D3700 drives use PCIe 3.0 interfaces. Intel says these are its first drives with support for the NVMe 1.2 specification, too. The company says NVMe 1.2 is designed specifically for use in high-availability storage systems. It provides the following features:

  •  80 SQ/CQ + 1 admin queue per port
  • WRR queue priority support
  • Dynamic multiple name spaces
  • Reservations
  • Scatter/Gather I/O
  • 1MB MDTS
  • CMB for Submission Queue

Intel also claims these drives will experience less than 5% performance degradation over their lives, and they'll provide 90% IOPS consistency, too.

    D3600/3700: Want. Need? Hell no – but definitely want 🙂

      Can afford? Depends on how attached I am to that second kidney…
