Hello, I bought a 1tb seagate barracuda wth 64mb of cache.
Model number is ST1000DM010-2EP102
Serial number: Z9ADGQK8
Firmware: CC43
I got Buffer: n/a using HD Tune

I have a really old samsung hdd as well and it shows 16mb at the buffer section.

Games are kinda running bad, because of hdd issuses, I believe.
It runs at 100% sometimes, when opening programs, when gaming, etc...

I've seen the cache information somewhere else as well, dont record where. But there it showed 0k cache for my seagate hdd.

Why it is showing that information?



One more thing, in the field Standard, Supported, Active, my seagate shows, respectively: ATA/ATAPI0- SATA II, UDMA MODE 6 (Ultra ATA/133), UDMA MODE 6 (Ultra ATA/133).

but my old hdd shows: ATA/ATAPI- SATA II, UDMA MODE 7(Ultra ATA/512), UDMA MODE 6 (Ultra ATA/133).

That means my old hdd has a higher udma mode? what it does even mean?


:::: just found out that my barracuda is SATA III, not SATA II as it shows.
my motherboard(h110m c/br) supports SATA 6GB/S (SATA III), and my processor is a i5-7400.


what is happening?


here's a HD TUNE picture.

now that I posted, i finally find something about it -.-

Why does the cache size say 0MB?

If your hard drive benchmark or diagnostic software identifies the buffer size as 0MB, your drive may actually have 32MB of cache. See your drive's published specifications for a confirmation. The maximum value that could ever be stored in word 21 is FFFFh. A modern disk drive with 32MB of buffer would need one more byte to represent the buffer size: 10000h. The first two bytes of 10000h (word 21) is 0000h, or zero.

Is that information correct?

The Sata II / III question remaing, why it is showing it is a SATA II, not a SATA III as it should?
