Less 5TB or more 4TB?

I am in the market for either a bunch of 4 or 5 TB drives.

My options right now are the
- Toshiba MD04ACA500 5TB
- Toshiba MD04ACA400 4TB 7200RPM
- HGST 4TB Deskstar Coolspin 5400rpm
- HGST 4TB Deskstar 7200rpm

Both the HGST have excellent reviews so I am feeling safe with them. But really I would prefer the 5TB size. The problem I am facing is that there is not many reviews of the Toshiba 5TB drives, they haven't been out that long, so we really don't have a big sample size to see how they are going.

I am using mostly Samsung 2TB spinpoints (about 6 from 2009 - all working a charm), and Toshiba DT01ACA300 3TB's - great also. The Toshiba are excellent so I am considering the 4TB ones too. I will be snapraiding these drives using 1 as a parity drive, hence I would rather less, but reliability matters above all else. Opinions are welcome. Thanks
 
If reliability is the #1concern then it's too soon to recomend any 5TB drive and of those listed I'd go with the 5400rpm hgst drive.

Note the hgst and Toshiba 7200rpm drives are almost identical.
 
What are your primary concerns aside from reliability? Speed? Heat? Noise? Capacity?
 
seems strange most of the >4TB drives are 7200 RPM instead of 5400
 
you should consider the Seagate NAS 4TB drives for date storage and reliability. I have 4 of them and they have run great for me. I sold my WD Red 3tb drives after a 25% failure rate.

I assume you mean some statistically insignificant quantity and not 250 drive failures out of 1 thousand drives?

I doubt HGST and Toshiba are the same, maybe in look but that's is because Toshiba got their older tech and HGST has not changed their drive look in ages.

Different company, tech, platform and facility.

HGST NAS so far have been solid, Toshiba's are one of the worst.

The reality is Toshiba should not even BE in the 7200 market, it was not necessary but the USA just had to inject it's equality BS into the game.

I haven't thought about anything other than reliability. Space is definitely what I want (since fewer drives is fewer drives to die...) but it seems the 5,6, 8 tb drives are just too new still to know how they handle. I think i will settle for the HGST coolspin, only hear good things about them.

Thanks all
 
I have a pair of 3TB and 4TB HGST NAS in my mid-tower and they have been rock solid so far.
Long transfers can slow down pretty badly, otherwise they are fairly quick for 7200.

The coolspins seem to have good reviews, probably can't go wrong with those either.

The NAS seems to be in short supply of late and their price has gone up yet again.
 
Toshiba and HGST are not identical. I think this misconception comes from the widely-quoted Anandtech article, which is wrong in many ways.

1. The article claims that Toshiba was not in 3.5" HDD business and only made 2.5" HDDs until the deal with WD/Hitachi. This is wrong. Toshiba made its own 3.5" HDD - for example, MKxx02TSKB 1TB and 2TB drives were available a good year before the deal with WD. They were just not widely known because of poor availability to retail channels.

2. The article claims that WD sold all 3.5" business of Hitachi to Toshiba. This is wrong. WD sold only a couple of designs and manufacturing facilities, namely, 1/2/3-platter Deskstar designs and Chinese factory. These ex-Hitachi HDDs are now sold by Toshiba under DT01ACAxxx model number. On the other hand, Thai factory, 5-platter designs and the entire Ultrastar product line were not transferred to Toshiba and still belong to WD/HGST.

3. Unlike DT01ACAxxx hard drives which are based on Hitachi designs and are limited to 3TB / 3 platters, Toshiba MDxxACAxxx and MGxxACAxxx hard drives (3TB/4TB/5TB) are not based on Hitachi designs, they are Toshiba's own development and are manufactured in Philippines on Toshiba's own factory. I think they are continuation of Toshiba's own MKxxxxTSKB product line. Therefore, it would be very interesting to have some reviews on them. I wonder why there are none, considering that the drives are cheaper than HGST and WD Reds, at least in my country.
 
It looks like this is a variation of the MG04ACAxxxA Toshiba Enterprise Drive.

See below a Google Translation of a review of the 5TB version from Amazon JP.
Good performance! It appears to have 128Mb cache according to a couple of sources I've found.
Available in Australia for $189 bucks for 4TB and $259 for 5TB from Pccasegear.com.au
4TB http://www.pccasegear.com/index.php?main_page=product_info&cPath=210_344&products_id=28123
5TB http://www.pccasegear.com/index.php?main_page=product_info&cPath=210_344&products_id=28124

Looks like I'll be replacing all my 3TB greens so I can go from RAID 10 to RAID 5 8x 5TB drives for 30TB. :) (2 x 4 disk RAID 5)

Amazon JP review

It was purchased or rather (which was purchased in the curiosity and a feeling of 5TB
capacity in March
HDD because it was less terrible).

It's a performance of its own way to meet only 7200RPM indeed, but the temperature is high anyway.
Or would not be higher by 4 ℃ enough average compared to the GREEN Series 4TB of WESTERN DIGITAL?
Sound so wearing also six FAN in case you do not take care ((laughs).

And for good measure... A review of the 5TB Enterprise model I referenced above. It lists a 205MB/s sustained transfer rate which all but matches the figures above from Crystal Mark for the MD04ACAxxxA model of the MG04ACAxxxA enterprise Drive. http://www.nikktech.com/main/articl...-nearline-mg04aca500a-5tb-sata-iii-hdd-review

I'm currently making a 12 drive RAID6 from MD04ACA400 - In process of buying drives, will be hooked up to Areca ARC-1284ML-24.

I have a MD04ACA200 which replaced a failed 2TB HSGT in a 16 drive array, and it's consistently running 2"C cooler than the HDS722020AL in the rest of the array. Based on that (and that its new-ish tech and hopefully fails less) I decided to make a 12 drive array of the 4TB versions.

I guess I'll find out if I trolled myself with these or not. They're around $135 here (blame garbage yen).
 
I know that this is an old thread, but I would be very interested in user reviews for MD04ACA400 and HDWE140EZSTA drives. I have for a few weeks now my first DT01ACA200, with which I am very satisfied. Faster then WD Green/Blue. About 2C lower temp vs WD Red/Green. 30% lower price and reliable so far. So, I am considering testing the 4TB drives. According to a some recherche MD04ACA400 and HDWE140EZSTA (also marketed as X300 series) may be the same drive. For the price diference of 30% against EFRX I would be willing to try them out. On the other hand I have four flawlessly reliable WD40EFRX with more then 500 work days. How does Toshiba work in mdadm raid enviroment?
