6000 io/s | Random I/O PerformanceSSDs are at least 15 times faster than HDDs | HDDs reach up to
400 io/s |
SSDs have a failure rate of less than
0.5% | ReliabilityThis makes SSDs 4-10 times more reliable | SSDs consume between
2 and 5 watts |
SSDs consume between
2 and 5 watts | Energy SavingsThis means that on a large server, approximately 100 watts are saved | HDDs consume between
6 and 15 watts |
SSDs have an average I/O wait of
1% | CPU PowerYou will have an extra 6% of CPU power for other operations | HDDs failure are fluctuates between
2-5% |
The average service time for an I/O request while running a backup remain below
20 ms | Input/Output Request TimesSSDs allow for much faster data access | The I/O request time with HDDs during backup rises up to 400-500 ms |
SSD backups take about 6 hours | Backup RatesSSDs allow for 3-5 times faster backup for your data | HDD backups take up to
