I am looking at the following two drives for a RAID device, which will be streaming normal things but also a lot of video:
- Seagate Constellation ES.3 ST4000NM0033 - hard drive - 4 TB - SATA-600
- TOSHIBA DT01ACA300 3TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5"
Will the 128 MB cache on the Seagate have an effect in my described scenario, compared to the 64 MB on the Toshiba? If so, what sort of difference can I expect?
I'm using a qnap device, if that matters.
Nobody here can tell you whether it's worth your money (except if the more expensive drive is worse in every way, but let's not assume that). You could try asking how to determine which drive is best for your use case instead, not asking for specific models... – Daniel Beck – 2012-12-17T18:39:42.987
@DanielBeck I thought I did. – johnny – 2012-12-17T18:40:36.023
I asked for video with the device specifically if 128MB cache was better than 64MB cache in the hard drive. Is it hype or a real difference worth the extra money. – johnny – 2012-12-17T18:41:53.293
I'm not sure why this was closed... It seems to me to be a legitimate hardware question, i.e. "Does extra HD cache make a difference when streaming video". We can at least present the pros and cons of large caches. He can decide if it's worth the extra cost... – BobT – 2012-12-17T18:47:41.367
@BobT Once a question gets hit for closing people jump on it. I've selected another forum but I was hoping for here. – johnny – 2012-12-17T18:49:15.537
2I removed the shopping-related parts from the question, including the prices, to make it purely about the effects of HDD cache. @johnny If you think I removed too much, do feel free to rollback to a previous revision. I also voted to reopen. – Indrek – 2012-12-17T19:44:15.953
@Indrek Thanks. I don't think anyone cares anymore since the question is older and closed, but maybe it will get opened. – johnny – 2012-12-17T20:13:15.300
