Reference performances stockage

Type	IOPS (4K)	Throughput	Latence	Prix relatif
NVMe PCIe 4.0	500K-1M	5-7 GB/s	<0.1ms	$$$$
NVMe PCIe 3.0	100K-500K	2-3.5 GB/s	<0.1ms	$$$
SSD SATA	50K-100K	500-550 MB/s	0.1-0.5ms	$$
HDD SAS 15K	150-200	150-200 MB/s	3-5ms	$$
HDD SATA 7.2K	75-100	100-150 MB/s	8-15ms	$
AWS gp3	3K-16K	125-1000 MB/s	1-2ms	$$
AWS io2	64K	1000 MB/s	<1ms	$$$$
Azure Premium P30	5K	200 MB/s	1-2ms	$$$

Formules

IOPS effectifs = (Read IOPS × Read%) + (Write IOPS × Write% × RAID penalty)
Latence = 1000 / IOPS (approximation simplifiee)
Queue Depth optimal = IOPS × Latence(s)

Conseils

Pour les bases de donnees OLTP, priorisez les IOPS
Pour l'analytics/streaming, priorisez le throughput
NVMe > SATA SSD > SAS HDD > SATA HDD
