I have about 8 or 10 DDR-2 and 6 DDR-3 modules which I don't really need any more. I wonder whether there's a 5.25" SATA hard disk drive that takes DDR RAM (you can recommend for DDR-2 or DDR-3).

From the size of a 5.25" drive I'd estimate that it could have ~10 slots but 8 would also be ok, so it would be able to be a 16 GB to 20 GB disk.

From the performance, it should be able to outperform an SSD when it comes to writing speed, i.e. it should be higher than 500 MB/s.

The price should not exceed 35 €.

  • You know that ram looses all its data the moment it gets no power, don't you? – Julian Kuchlbauer Aug 17 '16 at 13:17
  • @JulianKuchlbauer: yes, sure. It would take temporary data, e.g. as a cache for video editing or similar. – Thomas Weller Aug 17 '16 at 13:38
  • you can get 32gb ram in PC and create huge ram disk safely there. Why even bother with old ddrs? Just sold them on ebay.. – JIV Aug 18 '16 at 17:29
  • @JIV: Buying 32 GB or RAM for a RAM disk is ~200 €, Next I how do I put additional 32 GB of RAM into my PC when all slots are already full? And don't forget that I need to upgrade from Windows Home edition to Windows Professional. This exceeds the total cost expectations. – Thomas Weller Aug 18 '16 at 17:34

So technically, YES, there is such a thing: The Gigabyte i-RAM (second generation).

However, its performance is limited to the SATA I spec, so you're not really going to get a whole lot of good stuff out of it. It's also incredibly rare - but sometimes they do go for cheap.

It's probably a better bet to put those guys into a computer that can use them as a RAM disk and then make that network attached storage over a gigabit ethernet line.

  • I'd not like to waste that much power by putting them into a separate PC. Also: Gigabit Ethernet is limited to 125 MB/s. – Thomas Weller Aug 18 '16 at 8:09
  • Ah, but you can team it, and it's not limited to 4gb – Adam Wykes Aug 18 '16 at 13:19
