Toshiba berichtet über aktuelle Trends und zukünftige Entwicklungen bei den Komponenten zur Datenspeicherung – Mobil, zu Hause, in den Rechenzentren und in der Cloud. Dabei werden Szenarien basierend auf Speicherung mit Tapes, Festplatten und SSD anhand der Anforderungen in Sachen Kapazität, Performance, Leistungsaufnahme, Kosten und Produktionskapazitäten miteinander verglichen. Mit einem Einblick in neue Technologien aus den Festplatten-Entwicklungslaboratorien des Konzerns und unter Berücksichtigung der oben genannten Anforderungen wird es einen Ausblick auf die Datenspeicherlandschaft der nächsten 10 Jahre geben. Ein besonderer Focus im Bereich Festplatten liegt diesmal auf der Bewertung der derzeit kontrovers diskutierten SMR („shingled magnetic recording“) Technologie. Rainer Kaese ist seit über 25 Jahren bei Toshiba. Zunächst spezialisierte er sich auf anwendungsspezifische ICs, leitete das ASIC Design Center und später das Business Development Team für ASIC- und Foundry-Produkte. Derzeit ist er für die Einführung der Enterprise HDD-Produkte von Toshiba in Rechenzentren, Cloud Computing und Enterprise-Anwendungen verantwortlich.

SMR Technology Expectations
Enterprise
Enterprise Cold/Archive Data: ‘Host-managed’ SMR Drives
• 20+TB on a 18TB CMR Model,
24TB on 20TB CMR Model
• Limited Applications, specific Systems

SMR Technology Expectations
Client
Client / System Drives & Surveillance (non-RAID): “Drive Managed SMR”
- Inexpensive way to increase capacity and reduce $/GB
- Memory & Media Cache to cover SMR drawback (“random write issue”)
- Cache even increases random writing speed (in short-burst mode)

Random Write (64kByte) Performance CMR vs SMR
CMR 2TB 7200rpm SMR 4TB 5400rpm
~130 IOPS
~135 IOPS
>1400 IOPS
• Constant Performance ~130 IOPS
• Initial high performance (RAM Buffer)
• Then Media Cache Performance ~135 IOPS
• Sharp Drop wen Buffer and Cache full

Expectations on SMR Technology (RAID / NAS)
(Drive Managed-) SMR is (so far) not suitable for RAID
- Continuous writing is not compatible with SMR
- Will need a System Approach, most likely
‘some kind of host managed SMR’

HDD vs SSD: Driving Factor No. 1: Price / Capacity
Parallel prize trends for eSSD and Enterprise Capacity HDD!
SSD capacity trend:
• Ultra high capacity
• 16 TByte  100 Tbyte  …
• Linear trend price / capacity
HDD capacity trend:
• Increasing capacity
• 8 TByte  10 TByte (Air)  14/16 Tbyte (He)
• 18/20Tbyte (MAMR)  new technologies
• At similar costs/unit
• Few 100$

Why (still HDD) - Driving Factor No. 2: Storage Capacity
Market relies on HDDs!
How much Flash Storage can be manufactured?
• 2019 Total eHDD/cHDD Capacity shipped: ~890 ExaBytes (Mio TB) in 318 Mio Units
• 2019 Total eSSD/cSSD Capacity shipped: ~153 ExaBytes in 297 Mio Units
• Only to double SSD capacity shipped in 2019, approx. 100 billions $ additional investments for Flash fabs
are required
• It would cost the NAND Industry hundreds of billions of Dollars and several years of time to construct new
fabrication plants to displace 100% of HDD’s installed in 2019
• Within the next 5 - 10 years it will be impossible to manufacture a sufficient
amount of SSDs in order to replace the installed HDD base
