I love my 2 Hitachi 2tb &amp; wish to use as a internal data drive via Sata 3 connector. Are these "NAS" drives just as good as any Hitachi desktop drive?

As far as I know, there is no official standards body for the publication of hard drive standards. However, manufacturers have begun to classify their drives using three grades: Desktop, NAS (Network Attached Storage), and Datacenter. In general, Desktop graded drives are not designed to operate on a 100% duty cycle (turned on 24/7). NAS drives are the lowest grade specified for use in devices that are in continuous use. Datacenter drives are also graded for continuous use, but with an even longer MTBF (Mean Time Before Failure). In general the higher the grade of the drive, the longer the term of the manufacturer's warranty. However, be careful about judging the warranty because some drives are sold on the "gray market" and are not covered by the manufacturer's warranty. With all of that said, I should point out that a cynic might suggest that these drive "grades" are merely an invention of the marketing departments and that the extended warranty for the higher grades is merely a statistical risk which is completely offset by the higher price. In any case, if you purchase the Hitachi drive, before you install it check the warranty status on the Hitachi web site using the serial number. If the warranty doesn't meet your expectations, return the drive before you unpack it. I, myself, have three Hitachi NAS drives installed for desktop use. I highly recommend them.

I believe you can. Enterprise drives are more expensive than non-enterprise drives because they are more reliable which is needed in a NAS and has a longer warranty from the manufacturer (5 years). I've used non-enterprise drives on my NAS and believe me, after about a year, I'm replacing each as it "conks" out on me.

ABSOLUTELY. I have been using a pair of 3TB, a pair of 4T and a pair of 1 TB seagates for some time with no problems. I do not use any of their special back-up software. (KIK, Ph.D.)

The red ones are the cheap ones right? Because the cheaper versions are definitely the ones I got. I thought about getting the base model (without the hard drives), but just figured I could upgrade later, as they begin to fail. One at a time hopefully. I love my Synology Disk Station!

Kinda prefer hard drive docking stations actually. Especially ones straight up and down. Easier on the motor. One I'm using is Vantec e-sata in white. Think it only goes to 3TB so when I go to 4 TB I gotta look for a new one. I mostly prefer it because I can stick a 3-4 inch mini fan behind it if it gets too warm. And cases don't do much for heat dissipation even the ones that are supposed to. Only one that did they don't make anymore :(

Ya know, I've just not tested that. I'm using mine with three Hitachi NAS drives. I'm pretty sure the consumption would vary by the drives. 7200 rpm drives will certainly draw more power than 5400 rpm drives. I'd suggest you email their tech department. They are very responsive I'm happy to report.

I use both WD and Seagate for storage - I have a Blue Face WD10 EARS model, I've had that for about 7 years, I abuse it daily. On my other system, I bought a low-speed (5400 rpm?) Seagate ST1000DL - Which got some nasty reviews on Amazon - But I've had that for 2 years and no trouble, it's only for storage so I don't need the speed. I don't have any SATA3 HDD's at all, I don't have any motherboards that support it. I'll have to get an Add-on Card

In my single bay QNAP NAS I see a range of between 110* F and 118* or so. I see temp changes more from ambient room temp than operating load actually. In the winter the room where my equipment is is cooler, and probably its warmest now, as its in the 70's outside and there is no AC on. In my 4 bay QNAP NAS I have 3 WD and one HGST (an older 2TB model) and the Hitachi always runs about 4-6 degrees warmer (about 110-116*F) than the WD's but its a faster drive. As long as your enclosure has a good cooling setup I wouldn't worry about the temps much, but I probably wouldn't put one (or any other drive that wasn't a SSD for that matter) in a passively cooled enclosure. For what its worth I typically rotate out my drives from service by 4-5 years of use. I have had lots of Seagates and WD drives grenade well before that amount of time passes, but I have never had a Hitachi HD not still be going strong when I swapped it out. Hope this helps.

I purchased the 2-drive version, but if the same thing applies to this as other 4-drive NAS's, you'll want to install them at least in pairs (if doing RAID 0 or 1). If you're going to want RAID 5 (and if the 4-drive unit supports it, which I assume it does), you'll want to install all 4 for best results. Edit: The 4-drive NAS's I've used only allow for 2 arrays, so don't plan on having 4 separate single-drive arrays.

No. FYI---I had problems using two Seagate 3 TB drives that were on the recommended drive list, support got them working but they stopped after 1 day of use. I know that this unit has gotten good reviews and is an inexpensive unit. Not like other NAS, you'll need to install the software that's included on each computer that you want to use the storage with. Buy the way, Iomega support said Western Digital drives worked more consistently with it than Seagates.

I have 4 Western Digital Red 3TB drives in mine. It has been running non-stop since I bought it. The best investment I've made in computer hardware in long time. Segate and Western digital will both work in it. Not sure if differnt size drives will work though.

Jeffrey: 1st .. SAS drives do not come with USB cables. You do NOT use a USB interface with them. Your need a Raid or HBA controller. Many motherboards have on-board SATA raid controllers which are not designed for SAS drives. There are some "enterprise class" mobos with SAS controllers but they are very pricey. Most discreet Raid / HBA controllers (LSI / Adaptec are the best) use an 8087 internal host connector which branches out to (4) connectors on the hdd end. The hdd end connectors are dependent on whether your drives are internal / external. More info at: http://www.elpeus.com/categories/sas-mini-sas/external-sas-cables.html The biggest differences between SATA & SAS is that all SAS drives are enterprise class and designed for Raid whereas most SATA drives are not designed for Raid. SAS can read / write simultaneously and SATA can only do one or the other. For most SOHO applications the motherboard SATA raid will suffice. WD makes some very good enterprise class SATA NAS hdds. You will find better performance from SAS but the Raid controller / cables are not cheap. I hope this helped. Good Luck & have fun:) Oh, by the way, I'm still running my Seagate SAS drives with no problems. I'm a happy camper.

I personally have a 2TB installed, so i cannot speak for that. But i don't think it's an issue, since it's just a normal SATA to USB adapter, i don't think that there's going to be an issue with using a 3TB Drive or larger.

Yes. I did exactly that when I purchased my Synology NAS. The BlackArmor NAS was a piece of crap, but the drives are fine and the Syno. NAS will play well with them.

First, I must say, I am No expert on computer hard drives. That being said, I believe the Seagate Desktop 1 TB Solid State Hybrid Drive should be significantly faster than the Hitachi hts727575a9e364 drive. There are several important differences between these two drives which, Will effect the performance of these drives... 1) The Hitachi Drive you are referring to is a 2.5" Laptop drive; The Seagate Desktop 1 TB Solid State Hybrid is a 3.5" Desktop Drive. I recommend you compare your Hitachi drive with the Seagate ST1000LM014 1TB Solid State Hybrid Drive SATA 6Gbps 64MB Cache 2.5-Inch Laptop drive (if this for a Laptop). 2) Cache Memory - The general rule of thumb here is: 'the more cache you have, the better your drive performs.' Hitachi: 16MB vs Seagate Solid State Hybrid: 64 MB 3)Interface: Hitachi: SATA 3.0GB/s v.s.: Seagate Solid State Hybrid: SATA 6 GB/s 4) The Seagate Solid State Hybrid Drive includes 8GB NAND Flash Memory and utilizes Seagate flash management technology to deliver SSD-like performance. I definitely recommend buying the Seagate Solid State Hybrid Drive over the Hitachi hts727575a9e364.

Dr. Bozarth, I take all reviews with a grain of salt of course. I also noticed the disparity in the ratings between the two sites. I usually frequent thehomeservershow.com. Many of the forum members are I.T. Professionals, or like myself, a medical professional with a keen interest in technology. The Western Digital Green Drives were the go to drives in the past, but were not ideal for NAS/RAID situations. Many of the members have had good luck with the RED drives, but still recommend a program such as SpinRite or HD Tune Pro to evaluate the drive before putting it into service. I can only recall one situation where a member reported a DOA Red Drive, and many more situations where the Green drives presented problems. The recommended drives for your scenario would be the WD Red drives or the Seagate NAS drives. RAID-1 would be a good solution, and a cloud backup such as CrashPlan on top of that. I have personally purchased two 3TB Red drives and have had no problems with them in the 6-12 months I have owned them. Hope this helps.

I know nothing about the 2TB one. I bought the 3TB and that has been the first one I purchased from Micronet. So far, it works fine.
