I had a SparQ drive - I did the sums, and it was the most cost-effective. A whole gigabyte per cartridge! Room for everything! I still have it in a box somewhere. It has some weird old connection… ah, parallel port according to Wikipedia.

The mad thing about it was that the drive malfunctioned a few months after I bought it. I took it back to the retailer and discovered it had been discontinued. But they still had one out the back, so the assistant swapped it for my defective one. Phew! In hindsight I should have asked for a refund. But hey, with two 1Gb cartridges I had enough storage for a lifetime!
