I'm running Debian on a Lenovo IdeaPad with 8 GB of RAM and zram enabled. The CPU and memory are adequate, but the 2.5-inch 5400 RPM hard drive is the main bottleneck, and I can't currently afford an SSD. I've used KDE Plasma and Xfce for years. Xfce is generally responsive, but its Wayland support and some keyring/password-manager integration have been frustrating. KDE handles those features better, but booting and general performance become sluggish, especially after installing more software, and it can become buggy or unresponsive after opening several applications. I don't enjoy tiling window managers and would prefer a traditional desktop environment. Should I try something like LXQt, Budgie, or another option, or is the hard drive the real limiting factor?

There’s only so much tuning can do when the system disk is a 5400 RPM mechanical drive. You can experiment with zram settings and reduce startup applications, but increasing zram won’t speed up disk access and may even cause more compression work. I’d try LXQt or a carefully configured Xfce session for now, while treating an SSD—new or used—as the most effective upgrade. If Wayland is essential, check its current support for each desktop rather than assuming a lighter environment will support it fully.
The hard drive is probably the biggest problem here. A lighter desktop can reduce memory use, but it won’t make a 5400 RPM disk feel fast. If possible, look for a small used SATA SSD or a second-hand drive. You could keep your existing disk for /home or bulk storage and install the system on an inexpensive smaller SSD. Even a modest SSD would make booting and application launches dramatically faster.
If you like the general KDE workflow but want something lighter, Trinity Desktop Environment may be worth experimenting with. It resembles older KDE and can run comfortably on older hardware. However, it does not currently provide Wayland support, so it would not solve that particular requirement. Budgie is another traditional desktop that may perform better than GNOME or Plasma on a hard drive, although the actual result depends on the system and installed services.
LXQt would be a sensible first choice. It uses relatively few resources while still providing a normal desktop experience, and it should feel lighter than Plasma on a slow disk. A clean installation may be worthwhile if you have accumulated several desktop environments and their associated services. Just remember that applications such as web browsers can still consume far more memory and disk activity than the desktop itself.
LXQt sounds like the best one to test first. I’ll also check whether the existing desktop packages and background services are adding unnecessary overhead.
I’ll look into a used or smaller SSD and possibly keep the current disk for storage. Thanks!
