Intel presents new 3D NAND solid-state drives
Apart from making chips Intel is also a major manufacturer of solid-state drives. The company has reminded us of this fact with the release of two new SSD lines called Intel SSD DC P3320 and Intel SSD DC P3520.
The two new solid-state drive lines are the first ever Intel SSDs that use multi-layer 3D NAND memory. This type of memory is 1.3 times faster than single-layer NAND flash memory and in addition to this it also offers improved reliability, higher energy efficiency and better data integrity. However, chances are you will not be able to put one of the two new Intel SSDs inside your PC since they are designed for datacenters and cloud computing. The SSDs are available with capacities of 450 GB, 1.2 TB and 2 TB and they also offer U.2 2.5-inch and PCI-E 3.0 x4 form factors (just the 1.2 TB and 2 TB models). As to performance the DC P3520 and DC P3320 reach 1600 MB/sec of sequential read speed and 1400 MB/sec of sequential write speed and 356 000 IOPS when randomly reading 4K blocks and 22 000 IOPS when randomly writing 4K blocks. The prices of the two new SSD models are unknown as of now.
Along with them Intel has presented the SSD DC D3600 and D3700 solid-state drives. They use ordinary NAND flash memory but despite this they happen to be Intel’s first SSDs that can be connected to two host controllers at the same time. Thanks to this the SSDs offer improved performance and better data safety. The D3600 SSDs are available in 800 GB and 1.6 TB capacities, while the D3700 can be had with capacities of 1 TB and 2 TB. The drives reach 2100 MB/sec of read speed and 1500 MB/sec of write speed as well as 470 000 IOPS while reading and 95 000 IOPS when writing. Unfortunately the price of both models is also unknown.
