Pros: It's a 7200 RPM drive (which means quite speedy) that runs quietly and has high capacity. It's too early to know about reliability as of yet, but so far I've had no problems or reason to believe there will be trouble down the road. HGST drives in the 4TB config have been very solid for me over the last few years, and now as size expansion becomes an issue the 5Tb drives are coming into use here. Chosen for the reliability of other HGST devices and the 7200RPM spindle speed over the slower drives available from other vendors in this size.

Cons: Keep it cool! This means making sure you have sufficient airflow; it runs right around 100F (41C) at its "temperature sensor" point in my rack, which is ~3C hotter than a 4TB Seagate next to it -- but the Seagate is a 5900rpm device. With higher rotational speed and performance comes more heat, so do make sure to keep it cool.

Other Thoughts: IMHO a good choice for media and other large-scale storage configurations where rotating rust is still the most cost-effective option, provided your installation provides sufficient airflow.

5 out of 5 eggs One Of The Few You Should Consider 06/10/2015

This review is from: Intel 730 Series 2.5" 240GB SATA 6Gb/s MLC Internal Solid State Drive (SSD) SSDSC2BP240G4R5

Pros: These drives, along with the S3500 and S3700 series, have power-loss protection for data "in-flight" *as well* as "at rest." Don't be fooled folks; power failures DO happen and SSDs without this protection can be silently corrupted if it does. Those drives are UNSAFE to use for any sort of critical data AT ALL; how companies get away with selling them is beyond me. This is not theoretical either; I've had two corrupted over the last five years this way in "desktop" PCs.

These drives are a bit slower than the S3500s but a very solid choice. They are *not* the high-endurance type of unit; if you need that then pony up for the S3700. The cautionary note on endurance in write-heavy applications (e.g. database use, etc) is to beware of write amplification; since a SSD works in 4k block sizes and to change anything in a 4k block you must rewrite the entire thing a very small write turns into a 4k one internally.

With these drives now having come down a *lot* in price there's little argument against using them in any desktop PC as a system disk, or for that matter as a boot and OS device in a large server.

Cons: None.

Other Thoughts: Enterprise-class reliability in a reasonably-priced SSD. Do you really need the last little bit of speed if obtaining it means sacrificing data integrity? I think not.

HGST Deskstar NAS 3.5

Pros: These drives are FAST. Much quicker than the Seagate 4TB DM-series drives. They're a bit more expensive, but if performance is important the difference is likely worth it.

Unlike many others I've not had reliability problems with the Seagates, but performance is always an issue with rotating media, especially on a ZFS raidz2 config where writes require multiple physical writes to complete. Then again being able to lose two drives without losing data is a major comfort when you just can't get hosed. And no, raid (ZFS or otherwise) is NOT a substitute for backups!

Time will tell on the reliability front, but my initial impressions from a performance perspective are extremely favorable. These aren't SAS disks but for a SATA drive they turn in extraordinarily nice performance numbers and are competitive for what you get.

As with all computer hardware thermal management is important. If you're stuffing a bunch of these into a cabinet pay attention to airflow for best reliability. These appear to run a bit warmer than similar Seagate 4Tb drives I already own in the same cabinet (~3 degrees Celsius or so) and approximately the same as the 3Tb Seagates. Note the 4Tb Seagates are 5900 RPM .vs. 7200 for the others.

Caution: These are "advanced format" drives, as are all beyond 2TB. This means 4k sector sizes so when you install them make sure your software (or you!) properly align your partition(s) to 4kb boundaries or performance will be materially impacted, especially for writes.

Cons: None so far. Ask me in a couple of years.
