Intel's Optane devices made their entrance into consumer and datacenter markets this spring, but don't think for a second that the company is neglecting its other lineups of memory products. Not only is Intel expanding its production of 3D TLC NAND, it's also releasing two new lines of datacenter solid-state drives: the DC P4500 and DC P4600 series.
Between the P4500 series and P4600 series, Intel is releasing a total of six new drives. All the models pack Intel's TLC NAND and an all-new controller developed internally. As expected of datacenter drives, these SSDs use PCI express connectivity and the NVMe protocol. All models will be available as half-height, half-length add-in cards, and some higher-capacity variants be offered as U.2 2.5" drives.
The drives in the P4600 series are the most powerful of the bunch, particularly when it comes to write speeds. According to Intel, the highest-capacity 4TB model provides sequential read speeds up to 3270 MB/s, while sequential writes can go as far as 2100 MB/s. For random operations, the P4600 drives can reach 694K IOPS on reads and are capable of 228K IOPS when writing. Available capacities are 1.6TB, 2TB, and 4TB.
As for the P4500 series, Intel reports that the drives provide read performance on par with their P4600 brethren. The 4TB P4500 drive, for example, posts sequential read speeds up to 3270 MB/s and random read speeds up to 687K IOPS. The drives fall behind the higher-end models when it comes to writes, however, offering sequential writes up to 1860 MB/s and random writes up to 62K IOPS. The P4500 series drives will be available with 1 TB, 2 TB, or 4TB of storage space.
Intel plans a second quarter launch for all of these drives, so we'd expect them to hit the shelves sooner than later. The company hasn't announced pricing, though it noted that will offer five-year warranty coverage.
