Intel has but to launch their first CPUs supporting PCIe 4.0, however different elements of the enterprise are preserving tempo with the transition: community controllers, FPGAs, and beginning as we speak, SSDs. The first PCIe 4.Zero SSDs from Intel are primarily based on their 96-layer 3D TLC NAND flash reminiscence, slotting into Intel’s product line just under Optane merchandise and serving as Intel’s prime tier of flash-based SSDs. The new Intel D7-P5500 and D7-P5600 are codenamed Arbordale Plus, a codename Intel revealed final fall with out offering every other info besides that the unique Arbordale product was by no means launched.
The two new SSD product traces are the primary to fall into the D7 tier below the brand new naming scheme adopted by Intel in 2018. The P5500 and P5600 are closely-related merchandise that differ primarily of their overprovisioning ratios and consequently their usable capacities, write velocity and write endurance. The P5500 is the 1 drive write per day (DWPD) lineup with capacities starting from 1.92 TB as much as 7.68 TB, whereas the P5600 is the three DWPD tier with capacities from 1.6 TB to six.Four TB. These function the successors to the P4510 and P4610 Cliffdale Refresh drives, and as such we count on some follow-on fashions to introduce the EDSFF kind issue choices and QLC-based drives which might be nonetheless due for an replace.

The swap to PCIe 4.Zero allows a giant soar in most throughputs supported: from 3.2 GB/s as much as 7 GB/s for sequential reads, whereas sequential writes present a extra modest improve from 3.2 GB/s to 4.Three GB/s. Random reads now hit 1M IOPS in comparison with about 651ok IOPS from the earlier era, and random writes are nonetheless bottlenecked by the flash itself with a peak of 260ok IOPS from the brand new P5600.
Intel hasn’t shared details about the inner structure of the brand new SSDs, so we do not know in the event that they’re nonetheless utilizing a 12-channel controller design like their earlier era. Intel does tout improved QoS and a handful of recent options, together with a re-working of their TRIM implementation to scale back its interference with the efficiency of extra essential IO instructions.
