Hi everyone, I'm trying to figure out why my WD Blue HDD is so slow with random read/write operations. After defragmenting didn't help, I realized the drive is 1TB but split into two partitions. I thought consolidating everything into one might improve things, but it wasn't possible since moving data from the second partition was too time-consuming. I've seen benchmark results showing another drive spinning at 5900RPM with similar performance, especially for random tasks. It's the same WD drive, but a faster SSD is used as the operating system drive. Any ideas on what could be causing this issue or how to fix it? Thanks!
WD Blue models employ SMR, which can lead to reduced random speed. Your Seagate also operates at 5900 RPM, not 5400.
WD Blue drives offer a balanced performance, neither outstanding nor poor. If the drive appears outdated, it might simply be retaining functionality. The SATA data cable connected to it likely has markings indicating it supports SATA 2 speeds, which could explain the issue—possibly a downgrade in speed or compatibility. Factors like the motherboard chipset, the data wire, or both may be involved.
SMR drives work for a short time before they run out of available space to store new data. Their efficiency drops once they need to manage frequent overwrites. Because the drive is limited to 1 TB, it's best to switch it to an SSD (any type) or a larger hard drive.
This output looks typical. Whether it's SMR or CMR, consistent results are hard to achieve due to their mechanical design. I've got a reference file for my 8TB Seagate drive from CrystalDiskMark—read speeds match yours, but write speeds are slightly higher, though still not exceptional.
Everyone, that clarifies things! I had no idea about SMR. It seems like the process is designed to slow things down now. Probably works better if you combine partitions and defragment properly, so data isn't overwritten unless you're using a low percentage—like under 50% or 33% based on setup. I'm not sure which part handles the distribution decision, whether it's the operating system or the disk controller, but I doubt Windows will manage it intelligently like it does with SMR.
