1tb 7200 RPM 32MB vs 2Tb 5400 RPM 128Mb, which would be faster

[Chris Solomon]

I am running out of space on my primary HDD (500Gb 7200RPM). I am looking at upgrade options. The first drive I was going to get (ST1000LX001 1TB SSHD 32Gb NAND) is currently unavailible due to the NAND shortage (making the larger size NAND really expensive). so i was considering using either my a Hitachi 7K1000 (1Tb 7200rpm 32Mb cache) drive i already have, or getting a larger Seagte 2Tb (ST2000LM007 2Tb 128Mb cache). My system doesn't have any issues with heat, SO it can handle the heat of a 7200 RPM drive just fine (it came with a 7200 rpm drive). but I am wondering which of the two drives, would be faster from booting windows and applications. My steam library (all 1.5 Tb's of it) is kept on the secondary drive which i already upgraded from 1Tb to 2Tb (was originally 500Gb).

I can't afford a SSD of a size that would be an upgrade in capacity to what i'm using now, So if your going to say "get a SSD" don't bother to post. I can't afford a $300-$400 drive. I am looking primarily for upgrading capacity. If the drive just happens to increase performance a little, that is a bonus.

I just need to know which drive would work for that purpose better.

Drives:

Hitachi 7k1000
Cap: 1Tb
Cache: 32Mb
RPM: 7200

Seagate ST2000LM007
Cap: 2tb
Cache: 128
RPM: 5400

They have similar performance . I would get 2TB

Looks like your right. I just looked at the seagate specs for the 2tb drive, and it says sequential read is 140MB/s and the hitachi 7k1000, is just slightly slower. I find it hard to believe, but maybe rotational speeds aren't as important as they once were?

I found a newer model of what i just recently got for my secondary drive, it has the same specs, but includes something called multi-tier caching technology. don't know anything about that, but it sounds like a sales gimick to me.

The raw speed means almost nothing

raw speed.. you mean the RPM or something else?

[76561198343548661]

Here the RPM , For processors , the frequency

sorry, it's been a long day... so you were in fact refering to the RPM speed of the drive when you said "raw speed means almost nothing."?

[76561198343548661]

Yes , just look at the benchmarks

[Chris Solomon]

the RPM of a drive used to be an important factor when chossing a HDD, that, and the size of the buffers and the cache. I know that the importance of HDD buffers has decreased. but cache size seems to be making a comeback in importance (from looking at seagates newest HDD's and SSHD's. I wouldn't think a SSD would even need much of a cache. I remember traveling all over town to find a 500Mb 7200 RPM drive for my 386SX-40 years ago (early 90's) because 7200 rpm drives were supposede to be much faster than 5400RPM drives. Guess improvements in technology have rendered measured rotational speed irelavent when choosing a new drive..

Just figure out a hdd with more read/write heads

[Chris Solomon]

according to seagate, this drive I originally wanted, Seagate ST1000LX001, is 95% faster than a 7200 RPM drive. STUPID NAND shortage....

as far as ai can tell, there are no other SSHD's that have 32Gb of nand. even some of the 1Tb+ firecuda drives which have only 8Gb's of NAND are nowhere to be found anymore. those with the 8gb of nand are supposed to be 50% faster than a 7200 rpm, but like i just said those are becoming hard to get a hold of now.

[Chris Solomon]

I guess i could use my old 7k1000 and wait a year to see if the NAND shortage ends. On the plus side, it means i don't have to spend any money atm.

There are WD Blacks that have a 128GB SSD for a SSHD but they are pricey.

If you mean the WD Black 2 (Squared) that is not any sort of SSHD at all.
Those were 2.5 inch drives that are a completely separate 120GB SSD + 1TB HDD all in a single drive.

They came up with these to help solve the storage issue that smaller Laptops would have (like an Alienware M11 or M14). This particular drive, the SSD & HDD are separate and can be used as such; like OS on SSD, HDD for storage/games, etc... It did not take off well in the market because they came out when SSD pricing was generally ridiculous, and so was this drive; which was around $299 or so, IIRC

Also have to consider that HDD speeds never actually hold up over time if you are not defragging the drive, which many folks simply do not take the time to do, or understand that there is even a need to do that.

Yeah , defrag !!! Thus it runs at max
