[SOLVED] Does having no DRAM in your SSD only affect write speeds or does it affect read speeds too?

And does it affect sequential reads or only random reads?

It's mostly useful for write speed during a short period of quick burst (maximum performance mode).

In normal working condition, the DRAM cache has no significant advantage vs DRAM-less version, especially if your computer is slow (for example you use SATA 3 SSD on computer with SATA 2).

So I have a SATA II port in my PC and am think of getting a 520 MB/s DRAM-less SSD thats SATA III. So it will still be faster than the stock 100 MB/s HDD?

yes. even a dramless ssd will feel much faster for day to day usability vs a hard drive.

however, if you can, get a better quality drive with dram

Sure, even an Enterprise grade HDD spinning @15,000rpm can't be as fast as the cheapest SSD.

Even though SATA II locks it to 240-300 MB/s?

SSD will be faster, but id reccomending spending just a little bit more for a better drive with dram.

A better drive should only be $5-10 more but its well worth your investement.

The SSD is the only drive that is capable of reaching that transfer rate, I don't know of any consumer HDD that can be that fast.
