Hitachi 7K250 HD -80GB opinions for OS drive? Only 2 MB buffer...

[kayaksurfer]

I want to buy a new primary/OS drive and got excited about the 80G 7K250 from Hitachi, until I found out it only has a 2MB buffer.
(They're really vague about it, but they say that the 1 platter drives (40/80GB I think) have a 2MB buffer, whilst the larger drives with 2/3 platters have 8MB.)

Should I really care?

Thanks!

since it's on top of storagereview's leaderboard, i say, no, you shouldn't care.

oh nm they tested the 8 meg one eh?

 

[kayaksurfer]

Yeah but they tested the 250GB 8MB SATA buffer model.

There is 8mb cache ones for this 7K250 80GB, just try another shop since this shop doesn't know much, if you check it out from Hitachi website, you can easily finds this even with SATA's which I'm using.

You can get all sizes for the SATA drives with 8MB, but for PATA you're limited to 2MB for the low capacity versions.

I guess I could get a PATA 120/160 instead, or look into getting a SATA card...

I'm just confused ever since I benchmarked my old Cheetah 10K SCSI and found out how badly its sucking compared to my cheapie IDE drives, under winXP.

Everyone is like...."omfg, did he just say 10,000 RPM?" and they are selling all their posessions and riding around the country in a bandwagon that says 10,000RPM on the side. ooh, so your rotational latency is 3ms instead of 4.17ms, thats about it.

I moved up from IDE to dual 15krpm SCSI drives a few years back and it was the best upgrade I ever made. My system runs much, much smoother.

When drives with 8MB buffer first came out all the benchmarks said there was hardly any difference between 2 and 8. I haven't bothered to look lately, but the difference is probably still not worth worrying about.

Hey Sunase, how's the noise with those drives (spinning and actuator/arm)?
