Our have a look at the KIOXIA CD9P-R Gen5 Knowledge Middle SSD marks a primary for The SSD Assessment, and it’s a little bit of a nostalgic one. Our reference to the KIOXIA workforce stretches again a few years, all the best way to the early OCZ Revo and Vertex days. That lineage later turned Toshiba, and ultimately KIOXIA round 2018–2019. Since shifting our focus largely to retail and consumer SSDs a number of years in the past, our interactions with KIOXIA have principally come by tech occasions and European launches, particularly in our protection of the KIOXIA Exceria lineup.
Apparently, one in all our favourite previous articles ties into at the moment’s assessment. It featured a close-up cross-section of BiCS 8 NAND flash layers captured with a 1000x endoscope. That pattern showcased BiCS 8 QLC with a 32-die stack, not the 3-bit BiCS 8 218-layer 3D TLC NAND powering this new CD9P-R Gen5 SSD. Nonetheless, it was the primary time we’d ever seen actual NAND flash layers below magnification quite than a rendered diagram. Have a look:
Our report on the KIOXIA CD9P-R this morning highlights one in all two intently associated information heart SSD releases from KIOXIA: the CD9P-R and the CD9P-V. Whereas the 2 fashions share very comparable efficiency specs, the “R” model is rated for 1 Drive Write Per Day (1DWPD), whereas the “V” model carries a a lot greater 3DWPD endurance score. Consequently, the V mannequin gives decrease usable capacities because of the further over-provisioning required to realize that spectacular endurance degree.
We hope to have the CD9P-V in hand for a future side-by-side comparability, though with present NAND pricing, securing each variations of such intently associated enterprise SSDs is now not a certainty.
The KIOXIA CD9P-R is a PCIE 5.0 (Gen5) x 4 (4-lane) 1DPWD information heart SSD that follows the NVMe 2.0 working protocol and operates at speeds as much as 128GT/s. The pattern we have now in hand is of the newer E3.S kind issue and its steel shell measures roughly 4″x3″ and is just one/4″ thick.
Efficiency for the the CD9P is listed at 14.8GB/s learn and 7GB/s write with as much as 2600K IOPS learn and 450K IOPS write. This SSD is right for combined use eventualities and comes with a typical 5-year restricted guarantee. This snapshot from KIOXIA briefing supplies supplies a terrific comparable between the 2 completely different SSD efficiency specs:
Each variations of the CD9P could be excellent for purposes similar to Hyperscale computing, IoT and massive information analytics, OLTP, steaming media and content material supply in addition to virtualized environments, noting in fact the ‘V’ model is 3DWPD and has stronger 4K random write speeds.
The CD9P has further options similar to SIE/SED, performs at below 23w energetic energy, and has power-loss-protection built-in.
