I've recently learned there were other FDDs for the PC and XT than the infamous Tandon TM-100. One such is the World Storage FDD-211-5. How does the quality on these drives compare? Were there other companies' drives used in the XT lifespan?

FD-55E 96 TPI 80 Track 300 RPM

40 track Teacs were used in the PC and/or XT? That's quite a surprise. Was there a version with an IBM branded bezel?

Check the PC XT Techref (MZD has a copy)--IIRC there are schematics for at least three drives there. One of which, I believe, is a CDC/MPI drive.

MPI drives can be variable in quality. Some are no better than Tandons. Some of the older ones are well-constructed (mostly with the CDC logo).

Y-E made drives for other manufacturers as well. I've got a couple of Fujitsu drives that are clearly Y-E production.

I have never seen any of the World Storage drives. Those used to be Orbis and General Systems International in the 70s and became part of Wong Electronics in the mid-80s. Someone else may have encountered them in any of the other guises.

I liked the YE-DATA drives and had bad experiences with the only MPI drive I encountered.

Y-E made drives for other manufacturers as well. I've got a couple of Fujitsu drives that are clearly Y-E production.

I have 3 Y-E drives and they are all quite good.
I've got a couple of Y-E drives that I can't get to work:
