- Before I begin... the ELS series from Quantum is _not_ replacing the LPS
- series. Quantum is still producing the LPS series, although the older
- LPS drives (52LPS, 105LPS) will be discontinued soon. The newer 120LPS
- and 240LPS are still being manufactured. From my own experience I can
- say that they are really reliable and fast drives (the older LPS drives
- were reliable, too, but much slower). One drawback... you will probably
- never again see a drive as quiet as the 52LPS.
-
- Now to the ELS series. They are more a low cost, but high tech (fewer
- parts than the LPS series) alternative to the LPS drives. From what I
- can see in advertisments they are darn cheap and are equally reliable
- to the LPS drives (same MTBF). In terms of speed they are like the
- older LPS series... that means they are still fast drives, but cannot
- approach the speed of the newer LPS drives. I have found them to be a
- bit noiser, too. In terms of "numbers" I could say 250000 hours MTBF,
- 32K cache up to 64K cache (depending on size), 1MB transfer rate per
- second on my 68030 with a GVP controller. Not capable of synchronous
- transfer rate I believe, but default is asynchronous anyway... don't
- quote me on this though.
-
- If you have a 52LPS now and add a 85ELS to it, you shouldn't see a
- difference in performance at all. If you want more speed you need to
- go with the 120LPS drive.
-
- Why should I know? I called Quantum some time ago and discussed this
- with someone over there. I also bought a 52LPS, 120LPS, 42ELS, and a
- Maxtor 120 (noisy and slow like the 52LPS; I returned it). The ELS is
- over in Germany, but my two LPS drives are running 24 hours a day with
- no problems whatsoever.
-
- Hope that helped. (I used to be awfully confused about this, too.)
