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

I have the geeks.com (delock) one, and works fine with Seagate 9.5mm 750GB 7200RPM. Not sure how/why it would put a limit on drive size since it's just a dummy pass-thru from SATA to USB.

 

It has to translate from SATA to a USB mass storage device. This enclosure seems to use the same JMicron JM20316 chip as the Startech SAT2510BU2E which I had problems with. Many other enclosures on the market use the same chip and actually quote a 500GB capacity limit.

 

Not if you use the eSATA connection. eSATA is simply a SATA pass-through and uses USB for the power.

And it's the entire point of this thread.

 

anyone experience problem wit SATA HDD to USB 2.0 port cable?

as in the adapter(esata to usb) it run USB 1.1 speed instead of USB 2.0.

 

Forgive the necromancy, but this topic is still relevant to some of us on the internet ^^; And as eSATAp ports are still being placed on laptops, this might be useful to some.


So, I just finished reading this entire thread (every post over the past 26 pages) and have some much needed clarification on the comments I'm about to make. Please let me know if I am mistaken on any of these so I might correct them.




From what I gather there are 3 eSATAp 2.5" 9.5mm enclosures out there....

The DeLOCK 42465.
The Geeks HE-2521B.
The Startech S2510PESAT.

There is no data storage limitation on these enclosures minus that of the SATA standard's inherent limitations.

Only size limitation is the physical space inside of the enclosure for the HDD to be inserted. 2.5" and 9.5mm for all three.

The DeLOCK 42465 and the Geeks HE-2521B are the same product distributed under a different name. Both coming with the eSATAp cable.

The Startech does not include the eSATAp cable, which must be purchased separately.

eSATAp only uses the USB portion of the combo port for power. All data transferring is handled via eSATA.

The DeLOCK 42483(2) still has not been released.




Geeks appears to be out of stock again, but I was able to find some reasonably priced HE-2521Bs with a google search. I'm purchasing one from amazon as we speak to put my 640GB 5400 in

 

Very good summary +1. I think you'll be pleased with it. I know I am (have geeks version). Was hoping for the refresh to fit a thicker HDD in there.

 

Hmm,

I have one of these and they are widely available.

here

Thats what you mean isnt it?

 

Those don't have USB power and eSATA in a single cable to use the eSATA combo port.

 

the Delock #42465 and #42482 was phase out for the new product #42488. It's a combo of eSATA 6Gb/s and USB 3.0 :

 

Nice, except are there any machines with an eSATA 6Gbps? I thought they all still use the 3Gbps channel? In any case, will it accept a 12.5mm height drive? Is it available anywhere in the US?

 

The 42488 is available for resellers since April, I was supposed to be their reseller in Saudi Arabia, but I moved to Chile.

I don't know about USA. If there is enough buyers interested in this product, I may be able to negotiate with them a group transaction with different shipping addresses.

Now they even have this :

 

Those are some crazy (sleek) looking enclosures and with awesome specs to boot pkhetan. I had been scouring the German Delock site without any luck finding any new products. I never thought to check their Taiwan site for their new stuff ^^; After having that realization I found the new models easily in TW.

Though, I wonder if geeks will pick it up and start making some generic 42488 and 42492. My only reason for not wanting the name brand Delock is.... everyone who has a geeks says it works great with no issues and there isn't any outrageous shipping cost attached.

I also just got done emailing Geeks suggesting that they restock their HE-2521B and pointed them toward those two Delocks mentioned above. I can only hope they grab the ball and run with it. I really hope some company steps it up. Having so few choices for this type of product makes me fear it will be the next Betamax.

 

I'm now negotiating with Delock Taiwan. If things go good, then you can order internationally via me. I hope that they will give me affordable price for retail orders

 

That would be great pkhetan. If overall product and shipping costs are reasonable, I'll probably buy one.

 

I got my Geeks HE-2521B in the mail today. All I have to say is... "Why is this not in every store across the country (US)?!?!?!?!?!?" 3x times on average faster then USB2.0, small, sleek and attractive, 1 plug does it all, all parts and cables included. I'm an instant fan, it works great and I love it! I'm so glad I came across this webpage. Thank you to everyone who contributed to this thread and helped educate me in the ways of the eSATAp!

 

Well, soon USB 3.0 will more or less replace eSATA. Similar performance, and comes powered. Doesn't require a special port like a combo eSATA port.

 

I don't share your opinion brother. As long as the SSD's are built on a SATA interface, the eSATA will be the best choice and we will see more computer manufacturers that use the eSATAp ports on their machines. the USB port advantage is it's universal usage, i.e. you can use it for storage media, networking, security device, ....etc.

By the way, DeLock has replied. The 42492 is still not commercialized, only the 42488 is available right now. But the price that they gave me for 1pc order is really high. I'll try to negotiate to have the 50pcs price for retail also.

 

Also wanted to add that the Geeks HE-2521B is back in stock as of today. Already says the supply is almost gone, so if you want one from Geeks, now is the time

 

Understanding that the DeLock 42492 "is still not commercialized", what are the differences between the 42488 and 42492? I see that the 42492's description shows "for 1 TB". Is the 42488 still only supporting 500 GB or so? Other than this, are there any other known differences that I didn't see in the specs?

 

42488 can take up to 500GB drive
42492 can take up to 1TB drive, that's all.

By the way Delock Taiwan have accorded me $38 for the 42488 + shipping. If any one is interested, let me know. The shipping charge depends on destination, express or standard, and the quantity. The more the quantity is the cheaper the shipping fee per piece is.

 

What's shipping cost to USA?

 

EMS shipping : $25 for 1-2 pcs
Standard postal service by air : $17 for 1pc, $20 for 2pc

 

Hello,

I would be interested to order one to Germany too !

Though one thing that I was interested in is the eSATAp cable hidden inside the case (you said on 15/11/2010 that it was planned for the 42482/42483):


On the 42488 and the 42492, I don't suppose that we have such kind of feature ?

Regards,

 

No in the 42488 & 42492, there is no hidden cable. The project for the enclosure in your photo was unfortunately abandoned.

 

I've been researching these eSATAp enclosures, and I have a few questions about the power capabilities for more power hungry hard drives. I have been looking at getting a WD Scorpio Blue or Black 500GB hard drive, but as I explain below, it does not look like most enclosures would be able to power the Black version because it needs more than the 1A current supplied by two USB ports (2 X 500mA).


Both the DeLOCK 42465 and unbranded HE-2521B enclosures allow you to connect them to the computer using the eSATAp (Power over eSATA) cable and have a USB "Y" cable which allows you to draw power from two USB ports.

Main Question: When you connect both the eSATAp and USB Y cable to the computer, will these enclosures be able to draw a total of 1,500 mA from these ports (2 USB, and the 1 eSATA/USB Combo; 500mA from each port)?

Example: The 500GB Western Digital Scorpio Black 2.5" laptop drive requires a peak current of 1.15A to start spinning when it turned on. ( http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-701275.pdf) If this was placed in an external enclosure that is only powered from 2 USB ports (as would be the case with the enclosures that just have eSATA and USB) it would only be able to draw a total of 1A current since each port only provides 500mA, so the hard drive would not work properly.

With these two enclosures, if they allow you to draw 500mA current from the eSATAp port in addition to the 1A from the two USB ports, this would allow you to obtain the sufficient power to be able to run this Scorpio Black hard drive in the external enclosure.

For those of you who have one of these enclosures, have you been able to use them with any 7200RPM drives that require over 1A of current?

Have you ever found that a drive would not boot up when you only use the eSATAp cable and a single USB port, instead of both USB ports (or would not boot using the USB "Y" cable without the eSATAp cable)?

Do any of you know if these enclosures consume much power in addition to what the hard drive itself uses?

--------------------------------------------------------------
[UPDATE] 9-7-11

I sent an email to the [email protected] address that I found on the website, to ask if they are the manufacturer of the HE-2521B external HDD enclosure and to ask if the HE-2521B & 42465 enclosures are able to draw a total of 1,500 mA from these ports (2 USB, and the 1 eSATA/USB Combo; 500mA from each port), as I asked above. This morning I recieved the following response.

Based on this information, it looks like even though the 3 ports are able to supply up to 1.5A, the enclosure will limit it to 1A, so any hard drives that require a higher current to spin up will not be compatible with these enclosures.

Since these Delock enclosures are limited to 1A of current, it looks like the only functional advantage to using one of these types of enclosures would be if you had a hard drive that required less than 500mA peak current, so you could power it entirely using only an eSATAp cable. If you have a hard drive that needs more than 500mA, then you would need to use a USB cable in addition to the eSATAp cable, so this would be the same number of cables and available power as if you were to use one of the many other enclosures that utilize an unpowered eSATA cable plus a USB "Y" cable.

 

Hello,

I got the Scorpio blue 640 GB and the Scorpio black 500 GB and this Delock enclosure:
Delock Gehäuse 2,5 Zoll: Amazon.de: Computer & Zubehör

The Scorpio blue works perfectly with the enclosure. I can also try the Scorpio black but this is my main drive, so I'm not sure how to handle this.
I'll let you know.

Regards,

 

Dont mean to be a prude, but I am in the market for this type of an enclosure. So I thought I would revive this gem of a thread. I have gone and read every post in the past 28 pages as well. I understand what my options are. The question is how can I get my hands on one of the DeLock 42488 or HE-2521B.

I do not see any resellers for the DeLock in the US, and the Geeks.com unbranded version is out of stock.

 

A little pricey, especially with shipping - but how about these (at www.memorydepot.com):

• External 2.5" enclosure, USB3.0/2.0 to SATA HDD 1TB - 42483 - DELOCK
• External 2.5" enclosure, eSATAp + USB3.0/2.0 to SATA HDD - 42488 - DELOCK
• External 2.5" enclosure, eSATAp + USB3.0/2.0 to SATA HDD 1TB - 42492 - DELOCK

Agreed - I really wish some mainstream US resellers would pick up on this product line. Should probably be closer to $15 including shipping. As-is, the enclosure costs almost as much as the hard drive!

 

Yea, I really appreciate you finding those links for me. The total with shipping to Texas is coming out to $50. That does seem quite a bit pricey. I guess we just have to keep digging.

 

Sorry for resurrecting a seemingly dead post, I think this is still a relevant discussion.
eSata/usb combo is probably the most cost effective solution for external storage. I still prefer my eSATAp enclosure to my USB 3.0; probably because I only have one USB 3.0 port on my laptop, but I digress.

The 19 inch eSATAp to SATA 22pin Cable from Monoprice is probably the cheapest solution. Although, you'll have to provide your own protection for your hard drive. Also, keep in mind you can't power a 3.5 in drive with this.

Furthermore, as a FYI the generic version of the DeLock USB2.0/eSATAp is back in limited stock (18 as of 6/7/13.)
It says "Supports up to 500GB," but I believe that is for USB mode, not eSATAp. I could be wrong, I've never tried a drive larger than 500 GB. The cable above for sure will work on any drive.

 

Sorry to resurrect an old thread, but I'm in the middle of purchasing a new laptop with an eSATA/USB combo port and getting a new SATA III enclosure and disk drive is a high priority.

I just ran across this:
eSATAp & USB 3.0 2.5" SATA 6Gbps Hard Drive Enclosure | HDD Enclosures | StarTech.com United Kingdom

... as it's exactly what I'm looking for. Also optional cables are listed in the Accessories tab.

 

Can I ask who still makes a laptop with an eSATA/USB combo port?

I can't understand why most manufacturers dropped this type of port 3 - 4 years ago when USB 3.0 arrived. eSATA (provided it directly connects to the drive) bypasses any extra electronics which tend to slow down data transfers. USB 3.0 needs UASP to come close.

Both the Toshiba Tecra A50-A and W50-A have eSATA/USB combo port:
Tecra Laptops | Laptop | Toshiba

 

There's on one the back of my M4800 as well.

This Dell Latitude laptop was the only one I ever saw with eSATA and USB 3.0 combo port. Pretty cool.

Additionally, this is the cable to use for single cable connectivity:
3 ft Power eSATA Cable - M/M | eSATA Cables | StarTech.com United Kingdom

It provides power to eSATA without having to connect a separate USB cable to a USB port. My only concern here is why are these cables so expensive?

 

You can always use simple & cheap cable to connect the drive directly. Oh, and a lot of Startech products are very expensive.

 

Here's something similar on Amazon UK. I used such a product in the past when I wanted to connect to a bare hard drive and this solution has the advantage that there is no intermediate chip between the eSATA port and the SATA drive.

However, it's not so convenient if wanting portability with some protection although one of these or this will help or if wanting to connect to another computer with USB 3.0 (but this can be used with a bare drive).

I just picked up a Gigabyte P27g v2 and it has the esata/usb 3 port

Now that's an interesting machine. Frankly, I'm quite impressed of the Dell Precision line; if something occurs and I have to return my new Tecra W50-A after it arrives on Wednesday, that's my next stop.

Thanks for the post. :thumbsup:
