Does it make sense to use an SD card as an alternative for a slow hard drive?

Does it make sense to use an SD card as an alternative for a slow hard drive?

for example in an older laptop that still has an old slow IDE hard drive.

An SSD card always makes sense, especially at the current prices. This is faster and more durable, although I still use HDDs for backups. For example, I have had a WD Black for years and it does its job well.

Yes, an SSD is faster than an old HDD.

No, you should no longer do this on a computer that is still based on IDE connections, since we're talking about a 15-year-old system.

Are there any SSDs with an IDE connector? Had looked for it years ago and was surprised by the rather high prices.

But not with an IDE-based system… For more than 15 years only SATA disks have been used.

Yes again true, if SATA disks / HDDs.

I don't think an SD card makes so much sense… They are usually not designed for a lot of data to be written and they break quickly. There are exceptions, but I wouldn't rely on them anyway.

If you actually mean an "SD card" as written: No, it makes no sense. It is slower than a hard drive.

An SSD (solid state drive), on the other hand, does make sense.

SD card not SSD hard drive

But the Raspberry Pi also runs with an SD card, and is used by some as an office PC or for surfing.

It's about modern SD cards, not SSD hard drives. Because the cards are also used in the Raspberry Pi as hard drives

Yes, but it's about SD cards. Such as. In the Raspberry PI

Many use the modern SD cards in their Raspberry Pi as hard drives

SSD is also available for IDE, but I mean SD cards

Yes, but not everyone needs to be aware of the weaknesses in technology. Well, a little more detailed: There are different technologies for flash memories (SD cards, SSD hard drives) and the manufacturer always has to find a compromise between capacity, durability, compactness and price. SSDs tend to be more expensive, SD cards tend to be cheaper, so you have to save some money on the latter… Usually that's at least the lifespan. But there are the "High Endurance" cards, which are somewhat more robust. It is important not to let an operating system like Windows run from the card, or to outsource temporary files from Firefox, etc… This can quickly destroy the card. Linux has various setting options to protect the card.

Yes, then if I want to run Linux on it anyway. I don't leave the card in the SD slot either, but use a special IDE controller that can be equipped with SD cards. The SD card is said to be faster than a 2.5 inch IDE hard drive, but slower than an SSD. So something in between.

You can specifically look at the longevity of SD cards with Raspberry Pi. There you can get some input on what to watch out for…
