Haven't have any experience with Touro exts. Uncle Google shows the USB3 PCB board for Hitachi Touro Mobile Pro. Looks like it's a separate unit from the HDD PCB.

user posted image

It's listed as SKU #26196 for the HT parts no HTOLMNA5001ABB, HTOLMNA7501BBB & HTOMPNA10001BBB.

There's not much info available on the capability of the USB controller but seems to have a high rate of failures from the Newegg and Amazon reviews.

Hmm... but Toshiba's HDD used to be one of the most reliable in the market (think HGST comes to mind)


btw, just got myself a Seagate Backup Plus Slim 2TB from digital mall last Saturday XD

the slim drive with metal faceplate and the separated usb controller from the hdd is just thumbup.gif

think i will switch camp from WD to Seagate after I see for myself how the Seagate drives fares from now laugh.gif

Where did you get yours and for how much? You can get a ext HDD pouch to protect from bumps etc when it's not in use.

As for the Touro I think it may be more of a controller firmware issue due to the full formatting problem which a few users have also experienced.

Recently bought 2TB of Seagate Backup Plus Desktop version for RM252 from Lazada. Very very fast.

To be frank, I'm a bit disappointed with the pricing.

8 years ago, I bought my 1TB Buffalo at RM250.
Now I bought my 2TB Seagate at RM252.

The pricing just drop half. I expect more. Probably 4TB at RM250.

Pricing for hardisk are too expensive.

well, i think the price for hdd is steadily dropping albeit not "fast" as you would anticipate,

last year i bought a WD My Passport 2TB for 429, and now i bought a Seagate Backup Plus Slim 2TB for 360

But now that i saw Samsung launching their first ext SSD 1TB for almost 2k+, I am praying so damn hard for it to drop from heaven's price down to Earthlings' reachable price sweat.gif

Have you been tracking the exchange market? This morning - MYR 1.00 = USD 0.279954... down from USD 0.31776 on 28 Aug 2014, that's over 12% loss. It would be worse had BNM didn't intervene. Plus the effect of *real* inflation in Malaysia, any supposed savings have gone up in smoke. Not expecting situation to improve next quarter when GST hits.  cry.gif

BTW, be careful when you deal with Lazada. Just make sure you get the full warranty when dealing with them.
Crystaldiskinfo should show the internal HDD model.

Oh I'm long time customer of Lazada. First day Lazada is online, I already bought a few things. Probably spent more than RM10k in Lazada. Luckily haven't got any lemon yet. So I haven't test their warranty lol...

Thanks about the Crystaldiskinfo... will check tonight...

actually what is it about Lazada? They have shady sellers??? hmm.gif hmm.gif

I think Lazada is the greatest thing ever happen in Malaysia.

I bought motherboard from Hong Kong (Biostar disti Junmax). It arrived in 4 days. No warranty I think.

Beats me bro. I'll let Lazada sort that out with Dell.

I do like some of the stuffs they carry. Might be tempted to try one of these days...  smile.gif

oh.... then it is pretty much like you buy stuff off Amazon? where claiming warranty is on your own? hmm.gif hmm.gif

There has already been a lot of myths debunked on Backblaze's results. Just google them up.

The short version is, they use consumer HDDs in an enterprise environment. The HDDs are never off and are always running at maximum speed, they are never idle. If Seagate drives are so bad, then why does Backblaze keep using them? Because they are the cheapest. Just compare the other drives from WD and HGST, why so little units from them? That skews the chart entirely.

Sure their argument is that if the consumer HDDs can withstand their stressful environment, then it'll be of zero issues in a standard home usage. They also argue that Seagate drives fail but a similar drive from WD and HGST does not, that's their conclusion.

So WHY then do they NOT switch their entire cloud system to WD?! Why the HUGE disparity between units on HGST and WD in comparison to Seagate? Why then, don't they EVER use the same amount of units in the exact same stress test situation for all drives in their chart across the same platform? They never answered any of this, they just snuck their tail in between their legs and hope people forget until their next "annual" HDD failure report.

HAMR HDDs To Debut At 4TB Capacity But Reach 100TB By 2025

Heat-assisted magnetic recording (HAMR) is a novel process in which a small laser is used to apply heat to a disk so more data can be written to a standard platter. Some thought this was implausible, but Seagate says they will be introducing them next year for testing. Do you think mechanical hard drives are going to stay relevant thanks to these advancements, or will improvements in SSD capacity make them obsolete?

It seems that shipments of HAMR-based hard drives will start in 2018 after the tests started in 2016 probably end in 2017 and demonstrate whether HAMR tech is ready for mass production or not. To beat the rapid advancement of SSDs driven forward by Samsung, Seagate plans to make the new drives available only to select cloud and hyperscale datacenter customers, and only after that, the technology will move to the wide spread consumer market.

in my opinion, i think they will stay relevant as an alternative options, just like magnetic tapes still being used as backups for some companies hmm.gif

but what might shakes things up in the storage front might be next year's Intel Optane SSDs, though I am still skeptical about Intel's claim that the price would be "affordable" as new tech dont normally go with the word "affordable" sweat.gif

what i am not sure is about HAMR performance. will it end up just being another shingle hdd with good reads but not good constant writes. basically just meant for archiving purposes (e.g. videos, music, documents etc etc...)rather than for running your applications directly from (especially if it's something that runs constantly while in use like torrent client for example).

but then again for high capacity, people don't really expect performance, which they already rely on ssds for OS, games, apps... so i think the status quo will stay the same.

and yes i do think that optane ssd has a good chance to trump nand ssd because of the endurance, performance, storage capacity, the process to make is not too expensive (according to sources they speculate pricing to be somewhere between ddr4 and nand pricing. though with scale it might get cheaper).

nand recent developments are increasing the capacity size via 3d-nand, and other methods to cram in more storage space. the only way nand ssd's will still be relevant once optane comes out, is if they can produce nand ssds with high capacities and cheaper. otherwise people will just pass that over and go with octane.

then again like how people would for sure buy 1 single ssd for the os rather than hdd, people may now do the same once octane comes out. so nand ssd will have to take the place of what mechanical hdd was in that sense.

mechanical hdds seems like hamr is the next new thing after helium hdds, and shingle drives to renew the mech hdd platform. they too will be very reliant on having more space on the cheap to stay in the game.

but if you ask me, i think once nand ssds get to around 4, 6 or even 8 tb each, and cheaply, people will just get those and pop them into a NAS and use for storage. but the only downside is, they need to keep the NAS 24/7 operational, or at least scheduled to be on once every week because it was found that nand ssds begin to lose data if left without power over a few months or so. also make sure you only use ssds with some form of protection from sudden power loss, otherwise you are screwed down the line.
anyway about HAMR

https://en.wikipedia.org/wiki/Heat-assisted...netic_recording

For HAMR performance, I think the same like you, but if it is like a read-oriented drive, then I guess it can hardly pleases the crowd, but since it is aimed at enterprise at the moment, i think their endurance and reliability can be accounted for. But all these will only happen somewhere in 2018 according to kitguru, inbetween are some test production and prototypes, so still time to perfect the next drive.

Yea, I also agree on the paradigm that like how mechanical drive has shifted to secondary role as storage while faster NAND SSD would take the spotlight in running OSes and I/O intensive programs. The same would highly be happening when Optane is released, but I think unless the price is right, I doubt they would displace NAND so fast especially right now 3D V-NAND is ramping in production with Intel/ Micron, Toshiba/ Sandisk all disclosed their plans with 3D V-NAND.

Regarding the NAND SSD as NAS, I think the issue with them beginning to lose data if left without power over a few months is highly dependent on the temperature the drives are kept in. If i am not mistaken, JEDEC has outlined a few classes or minimum requirements in order for the NAND SSDs to be able to be sold. There are a few operating temperature ranges (classes) which would require the NAND SSD to hold their data (data retention) for a determined duration and if they passes those regulations, only then they are allowed to be sold.
