Is a 128MB hard drive cache worth the extra price over 64MB?

Is the 128MB cache on a hard drive worth the extra money over a 64mb cache? I am using a qnap for video. Thanks. 64mb is much cheaper.

edit: this is also raid 5.

Not unless all you do is large sequential reads, and then it would be a minor improvement. And nice choice -- I love QNAP boxes.

I would go with the 64mb cache drive, like I have the past few dozen that I've built.

And welcome to Tomshardware.

where are you seeing the drives? i don't see any hard drives on newegg with a 128MB cache. i found one on amazon but its a 4TB drive that's $250.

What do you think about synology? I like the sas option.

Synology are also excellent boxes, I tend to use PCIe cards (Adaptec, LSI) more often but for NAS drives both are great options. I don't see SAS as a huge plus for typical home/small office users in an NAS box, but the flexibility between SAS and SATA is nice.

be sure you can use more that 2TB of space in those boxes. I've ran into a couple that the larger drives would work but limited you to 2tb.
