Conversion Formula
KB/s = MB/s × 1000
About Megabytes per second
Megabyte per second (MB/s) = 10⁶ B/s (SI). Standard for storage benchmarks and USB speeds. NVMe SSDs: Samsung 990 Pro (PCIe 4.0) = 7,450 MB/s; PCIe 5.0 drives = 10,000 MB/s; SATA HDD = 80-220 MB/s. USB 3.2 Gen 1 = 625 MB/s; USB4 Gen 3 = 5,000 MB/s. Memory: DDR5-4800 dual-channel = 76,800 MB/s. A 4K RAW cinema camera generates ≈1,000 MB/s. 1 MB/s = 10⁶ B/s = 8 Mbit/s.
About Kilobytes per second
Kilobyte per second (KB/s) = 1,000 B/s = 8,000 bit/s (SI). Legacy modem throughput: 56 kbit/s dial-up ≈ 7 KB/s; ISDN 128 kbit/s = 16 KB/s. RS-232 at 115,200 baud (8N1) = 11.52 KB/s. CD-ROM 1× = 150 KB/s; 52× = 7,800 KB/s. Bluetooth 2.1 EDR ≈ 300 KB/s; USB 1.1 Full Speed = 1,500 KB/s. 1 KB/s = 1,000 B/s = 8 kbit/s.
