6000 io/s | Random I/OPerformanceSSDs 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
