eSATA external hard drive enclosure that supports power from combo USB port?

It looks like it might take 2 cables if you're using eSATA, one for power through USB and the eSATA for data, but it's hard to tell for sure. The mention of being able to connect via SATA for a desktop makes it a bit confusing.

The point of the other enclosures mentioned in this thread is that they only need one cable, connected to a combo USB/eSATA port located on the notebook.

 

Oh, I see. So it's only for the special port and only for notebooks. So that's why it's so rare.

 

I got me one of these: Amazon.com: Shared eSATA Cable for 2.5" SATA Laptop Hard Drive: Electronics
Not from Amazon, but the cable looks the same at least (I guess there's a PCB on the SATA side?).

It's kind of geeky, but hopefully the SATA connectors on my 2.5" hard drives won't wear out too soon.

 

Well, it's not _only_ for notebooks, as in theory you could put a combo USB/eSATA port in a desktop, but in practical terms, this will almost never happen because desktops both tend to come with a plethora of extra ports (both eSATA and USB), and by their nature, can often easily just have the external drive use a regular AC adaptor to plug into their power strip.

 

So what is consensus so far regarding read/write speed of esata and USB 3.0. I just received my Delock 84402 | Cable eSATApd > SATA 22pin. Works great. i plugged it in two different hard drives 320gb and it worked fine. However, the speed was not spectacular.

(quick test, no benchmarks)
What i did was plugged in a USB 2.0 external hard drive along with another hard drive connected via esata. Then i proceeded to copy 5 video files (2gb total) from my main machine to the 2 hard drives. Of course the Esata transfered quicker but the speed was not exactly astounding. Again, its quicker but not exactly "impressive". Maybe i was expecting to much.

Im very curious what a similar Delock cable with USB 3.0 could do...

 

A lot will depend on the speed of the hard drives themselves in question. If those are 5400 RPM drives in there, then the maximum bandwidth of the eSATA will already usually be higher than the drive can take. Thus going up to USB 3.0 with its higher maximum bandwidth is pointless; the drive is already choking and can't take anymore. As I see it, at this point, the only major advantage of USB 3.0 is the same reason this thread exists; power and data at high rate via a single cable.

Edit - well, ok, maybe when SSDs become widespread in use as externals, but I think we're a bit of a ways off from that point still.

 

Thanks for the link I also decided to get this cable since I couldn't find an enclsoure for a good price. I also got a $5 silicon laptop drive sleeve on ebay.. free shipping

 

A few days ago I contacted Delock about getting the #42465 in the US. After being forwarded around the world (China, Germany mostly) by friendly Delock employees, I ended up in touch with a Canadian named Vincent who will soon be stocking them and shipping them to the US.

 

So I have looked through this thread and unfortunately don't speak or read German. Is the DeLock the only enclosure that supports power over eSATA??? I have been looking around for a while now, but all the enclosures that say they have power over esata, then have reviews with people talking about using a USB cable as well.

 

I haven't found anything yet either. I'm still waiting for Geeks to restock their model.

 

The Canadian said that he'd recieve his stock in a little over a week on July 22nd. I'll keep you guys posted.

 

I know that the Silverstone Raven RVS01 external HDD enclosure allows you to utilize eSATA using two USB connectors without the need for an external power adapter. I wrote a review on it at NB-C:

Editor’s Choice: Silverstone RVS01 External HDD Enclosure Review - Notebook-Cooling.com

 

There are a ton of those enclosures that need two cables or more on Fleabay with prices starting at less than $15. Try this search: Esata to SATA HDD Enclosure 2.5". Make sure to read carefully the descriptions as some do not included the eSATA cable.



What we want is an enclosure that can be connected via:

- USB.

- 1 cable via Esata port for data + 1 or 2 cables connected via USB for power.

- 1 cable via Esata port for data + a 5V 1A A/C power adapter.

- 1 power over eSATA special cable via the Esata/USB combo port found on some of our laptops for both power & data.



I have such an enclosure since several months, works fast & stays cool but can't find an other one anywhere! It's an unbranded Delock for half the price: HE-2521B.



Now Mangosango posted in this thread a report & benchmark of his StarTech S2510PESAT which is a POE enclosure. Problem is it's overpriced @ $30 considering they don't even included the POE cable which is the reason to get that enclosure in the first place but since it seems that nobody can find the HE-2521B or an alternative so I guess that's what I need to get now as I need a second enclosure. Should have bought 2 or more HE-2521B's when they were available. Dam USB 3.0 enclosures cornering the market!

 

If that delock becomes avaliable, please let me know via pm.

 

I'll try to remember to

 

I just have received and plugged in a DeLock 42465.
I like this enclosure - it's pretty compact, but very robust, thick solid cast aluminium shell. The design is pretty clever and allows using enclosure as "quick swappage" platform, if you don't put a shell on and just plug HDD in, ie. for temporary work on it.
Works like a treat both in USB and eSATAp mode.

My laptop has both eSATAp and USB 3.0 ports, but after much deliberation to choose eSATAp. Pretty much the same price, but
a) no filtering between drive and PC, ie all stuff like SMART, HDD passwords, etc. work 100% natively
b) drive seen by all OS like *native* drive, starting from BIOS screen, ie. you can actually install Windows on it and boot from it, i.e. if you want to try temporary setups or recovery stuff.

I've almost bought a Startech one, but luckily I've realised that they don't bundle eSATAp cable with it, and these cables are insanely pricey by themselves for some reason (I mean, +10 pounds for 2 additional wires - come on!)

 

May I ask where you got your DeLock 42465 & @ what price?

 

I've got one from AVIDES Media (German company, ships to UK). It did cost be approx. 30 GBP (including shipping). Not too cheap, but cheapest choice including cable that I've found.
However seems that one I've bought was the last one AVIDES had in stock.

 

<s>I'm making a list of users to contact with information once Vincent has his DeLock 42465's in stock and ready to sell. (which should be in under three days)

So far I have: cazper37, Shawnm2, mofogx</s>

Power Over eSATA Cable)
they have the power over esata cable on fleabay for under 10

 

I was thinking about buying it too, but then your hard drive enclosure must support power over eSATA too. Here is my question/answer dialogue about exactly this cable:

Q: I have an external eSATA drive and to connect it to combo USB/eSATA port in my laptop I have to use USB cable to power the drive in addition to eSATA cable for data transfer. Will this cable allow me to use it as the only cable for both data and power and get rid of the USB cable? Thanks!

A: This would work if your external drive is a combo port esata/USB however from what you have described it is not. I think the cable you need is my item 290371310623 with a mini USB or my item 290419232729 full USB A male.

So I'm thinking about buying the first item he listed. Still one Y cable (eSATAp on the laptop side -> eSATA+miniUSB on the enclosure side) is better than two (eSata on both sides + USB on both sides) cables that I have to use right now.

 

Thanks a ton! I just got my laptop delivered today so I need to get this external hardrive soon

 

Add me too! I just got my M4500 in the mail. Thanks!

 

Added.

That looks like a great laptop!

 

I'm about to get a 4TB external hd WD MyBook Studio II and planning to use eSATA/USB combo port on my Dell SXPS 1645.
I'm not really clear of how eSATA works and read somewhere that it will require a separate power or power-over-eSATA cable which WD didn't include in their 4TB package.

Can anyone help to confirm from the spec of WD Studio II whether the eSATA/USB combo port in SXPS 1645 will work? and what kind or sample of eSATA cable is required?

My Book Studio Edition II 4 TB Hard Drives ( WDH2Q40000 )

EDIT: After going through some reading, as long as we're using a desktop 3.5" external hd which will definitely also use a power adaptor, a normal eSATA cable will work just fine. But if we're using a portable 2.5" external hd, then a powered-eSATA cable will be required instead.
Is my understanding correct?

 

How I understand this:
There are essentially 3 participants involved in the process: laptop eSATA port, eSATA cable and HD enclosure with eSATA port. HD needs power operate. There are several ways to provide the power to it.
First, AC adapter connected directly to the enclosure. If this is the case - you do not care about power with eSATA cable or laptop eSATA port as you already have a power source for HD. Any eSATA port on the laptop and any eSATA cable with or without power over them would work as you already have independent power source (AC adapter) for your HD. Downside - you enclosure has 2 cords (eSATA cable and AC adapter) attached to it. And you need wall outlet for AC adapter. Still, looks like it is the only option for 3.5'' drives.
Second option is USB (full or mini). Actually it works just like AC adapter except you don't need wall outlet for it. Downside: you still use 2 cords (USB for power and eSATA for data) and 3.5'' drives are out of luck because usb does not provide enough power for them.
And finally, the third one which is discussed in this topic. When you used eSATA cable for both power and data. To make it work all 3 participants (laptop eSATA port, eSATA cable and external eSATA enclosure) have to be able to work with power over eSATA. On the laptop side of things it is solved by eSATA(data)/USB(power) combo port. Next in the chain is eSATA cable. If it is simple eSATA cable - you are out of luck, it can not transmit power from the laptop to the enclosure. If it is powered-eSATA cable you are good to go as long as the enclosure also has powered eSATA port. And this is important because majority of the enclosures do not have powered eSATA port, just regular eSATA (laptop can provide power, cable can transmit it, enclosure can not accespt it on the eSATA port - we are out of luck again). That's why people are hunting for DeLock 42465 enclosure because it does have powered eSATA port.

When I said that for USB (second option) you have to use 2 cables it was not completely true. There is another option (and I'm leaning to it because I already have external enclosure which does not have powered eSATA port). It is a cable that has powered eSATA port on one end (which plugs into eSATA/USB combo port in the laptop) and splits on the other into eSATA and USB plugs (wich plug into eSATA and USB jacks of the enclosure).Technically it is 2 cables (usb and esata) combined into one Y cable and this meets my goal of having just one physical cable.

 

Cool, that gives me much better understanding.

So in short, 3.5" will have no problem in power, port, and cable since they are mostly (maybe all) using an AC adapter to power up everything.
While for 2.5" that's where the power, port, and cable are playing their roles.

Correct?

 

Sounds about right.

 

In short 3.5" HDD uses it's own power source & will connect to the laptop for data ONLY via the eSATA part of the eSATA/USB combo port.

 

Vincent has them in stock!
<s>I'll PM everyone with whatever contact info he tells me to give out.</s>
He was happy to gain more non-eBay customers
PM me if you want his email and weren't on the list.

 

My 42465 has a tracking number
not shipped yet but... FINALLY!

 

Mine too! I can't wait to get it in the mail.

 

How much is it?

 

It's about $35, insured shipping from Canada (to the US) is about $13

 

So it's about the same price as the Delock on Amazon_UK or the Startech S2510PESAT w/o cable + a separate Power Over eSATA cable. The unbranded Delock: HE-2521B @ $14 was a better deal. I wish I bought 2 as the one I have works fine since 3 months. Thanks for the effort.

 

D:
I don't like the review on amazon.co.uk.

 

Oddball defective product as we are about a dozen owners on the Vaio_F thread w/o any problem.

From Taiwan: Tragant International Co Ltd: "Brand Delock and Navilock", exact same as my unbranded HE-2521B.

 

Good.
I re-sent the product request... That's the link I sent them before.

 

With stories like these i'm always wondering what happened next.
Did he just ask for a new one, got it, and it's still working without issues?

 

lol...i just kept misreading your post and couldn't figure out what it was that you resented

 

grrrrr doublepost

 

Added a hyphen (even though resent is correct)
Even I misread it when I read what you quoted... lol

 

please let me know as well. Thanks!

 

You need 5 posts before you can send or recieve private messages :/
If there's an email address you wouldn't mind sharing to the internet, I could send Vincent's address to you there.

 

I need a few more of these. Anybody know of anyone with some stock currently?

 

Vincent just had his new stock arive on friday

 

The unbranded Delock 42465 is back on Fleabay for $20 (I got one of those since 4 months), just search title & description HE-2521B and they ship worldwide for $34 total.

For people in the US, Geeks has it here for $14 + shipping = $20 total.

See my old post about it here w/ more photos: VAIO_F Power Over eSATA Port & ext Enclosures Benchmarks

 

Got the Geeks.com HE-2521B today. Threw in a 320GB 7200RPM Seagate Momentus I had in there, connected it to powered eSATA and works like a charm.

 

I want to thank everyone who contributed to this thread. I just got my HE-2521B from geeks.com and it's exactly what I wanted. Works beautifully.

 

Good.

Could you post an HD Tune Read benchmark default setting, 64 kb size? I would like to compare to my 7200.4 500 GB which bench higher as main drive or in ODD bay w/ an HDD caddy vs in the HE-2521B in normal Win 7 mode while it benches higher & equal to the other configurations in Safe Mode.
