Hi

I have ssd and 1TB hdd 7200 rpm.

I want to buy new hdd.

I like wd Black but it is expensive.


Now which hdd should I buy? (for lifespan, reliability, low noise)

1- Samsung 850 Evo 250GB + WD Blue 3TB WD30EZRZ

2- Samsung 850 Evo 250GB + WD Red 2TB WD20EFRX

What's it for ?

1. Here's the failure rates for consumer drives in a consumer environment for the most recent 6 month period... the relative rankings have not changed in a number of years.

http://www.hardware.fr/articles/954-6/disques-durs.html

Seagate 0,72% (contre 0,69%)
Toshiba 0,80% (contre 1,15%)
Western 1,04% (contre 1,03%)
HGST 1,13% (contre 0,60%)

2. 3 TB and larger drives have a higher failure rate than 2 TB drives... tho this is shrinking over time. As you can see the 3 TB WD Black has a rather high RMA rate ... 6.4 times higher thn the 2 TB model.

3,04% WD Black WD3003FZEX
0,45% WD Black WD2003FZEX

I would avoid the larger sizes for a few more periods.

3. If we use the 2 TB WD Balck as the...
What are the drives being used for? Both those drives are 5400 RPM, so they'll be slower than a 7200 RPM drive. If they're just being used for bulk storage of video, data and so on, that should be fine, but if you're loading things like modern games off of them, the load times could be somewhat slow. I take it your OS is going on the SSD, so that wouldn't be a problem. 5400 RPM drives generally should be quieter than a 7200 RPM drive though.

3. If we use the 2 TB WD Balck as the "bar" at which to measure all others, we can compare the individual dribe reliability data below ....note that the absence of a drive on the list isn't indicative or anything good or bad , just that it didn't sell enough units for the numbers to be statistically relevant.

2 TB Drives
2,39% Toshiba DT01ACA200
1,25% WD Red Pro WD2001FFSX
1,10% WD Blue WD20EZRZ
0,82% Seagate Barracuda 7200.14
0,81% WD Red WD20EFRX
0,77% Seagate Enterprise NAS HDD ST2000VN0001
0,74% WD Purple WD20PURX
0,72% WD Green WD20EZRX
0,56% Seagate NAS HDD ST2000VN000
0,45% WD Black WD2003FZEX
0,43% Seagate Desktop SSHD ST2000DX001
0,41% Seagate SpinPoint M9T ST2000LM003

3 TB Drives
3,04% WD Black WD3003FZEX
2,89% Toshiba DT01ACA300
2,29% Seagate Enterprise NAS HDD ST3000VN0001
2,23% WD Red Pro WD3001FFSX
2,18% WD Green WD30EZRX
1,52% Seagate Barracuda 7200.14 ST3000DM001
1,41% Seagate NAS HDD ST3000VN000
0,96% Western Red WD30EFRX
0,75% Seagate Surveillance HDD ST3000VX000

4TB drives
2,37% WD Purple WD40PURX
2,02% WD Red WD40EFRX
1,89% Seagate Desktop SSHD ST4000DX001
1,53% Seagate Desktop HDD.15 ST4000DM000
1,04% Seagate NAS HDD ST4000VN000
1,02% WD Blue WD40EZRZ
0,95% WD Green WD40EZRX
0,90% WD RE WD4000FYYZ
0,56% Toshiba MD04ACA40
0,40% Seagate Constellation ES ST4000NM0033

With the Black at over 3%, I'd be more concerned about the blue... the Red and Green are generally subject to lighter loadings.

4. What is it going to be used for ? Here's the gaming test results from THG

http://www.tomshardware.com/charts/hdd-charts-2013/-17-PCMark-7-Gaming,2915.html

Seagate Desktop SSHD (2 TB, 7,200 rpm) - 9.76 MB/sec (50% faster than anything on th elist other than the 10k raptor)
Hitachi Deskstar 7K3000 (3 TB, 7200 rpm) - 6.83
Toshiba DT01ACA300 (3 TB, 7200 rpm) - 6.68
Seagate Barracuda 7200.14 (3 TB, 7200 rpm) - 6.43
Western Digital Caviar Black WD2001FASS (2 TB, 7200 rpm) - 6.34


5. Unfortunately I can no longer bring up noise in the charts

In summary, the Red drive you listed has almost twice the failure rate of the the faster 7200 rpm WD Black.... the Blue has more than 6 times the failure rate of the 2 TB WD Black. If gaming is on the table, the SSHD is 50+% faster and the failure rate is lower than the 2 TB WD Black.

We use the Seagate 2 TB SSDs as the 7200 rpm speed and built in SSD significantly help on both our workstation and gaming boxes. After all, if it ain't on that 250 GB SSD, you get zero benefit from having one. We have nought nothing else going on 7 years and have yet to experience a single failure. If the SSHD is not attractive to you, I'd opt for the smaller WD Black 2 TB

Hope the above data is useful in making a determination.
