Hallo!

In my ET10k eSATA link has download speed about 45MB (mega bytes) per sec. and upload speed about ... 10 (ten!) MB/s (10GB movie by about 20'...). What should I do to increase speed (especially upload - to send data to external HD) to sensible value?

It's my first post - sorry for errors.

What filesystem is used? Ntfs? Ntfs is a not a very good choice in this case, because it's slow.
Ext filesystems are faster but you get problems with Windows (there are drivers available) and you have to format your disk (=erase all content).

Yes. NTFS on GPT. I need acess from Windows7. Maybe slow, but not SO slow...

I use HD in box 2xHD (Unitek Y-3355) and aditionally have problem with second HD, invisible by ET10k (it's support Port Multiplier).

I think betacentauri means access from Linux is slow. IIRC we include the version over FUSE, which means all data must run through a program in user space, which doesn't exactly make it faster.

[betacentauri]

Yes, I mean slow when using under Linux. Especially on receivers with not much CPU power.
If you have another (external) hdd with esata port try with ext filesystem and you know more.
Sorry have no experiences with esata on et10k.

[kuszmar]

Thanks for both. Tomorrow evening I'll prepare HD with ext3(or 4).

[MiLo]

Do it from the box, it wil optimize the disk for recording.

[kuszmar]

Ok. I've formated old Samsung HD161HJ by GParted (from PupyLinux 5.28) as GPT Ext4 (sorry MiLo, my be tomorrow...).

Speed eSATA (both direction, ET10k<->Unitek Y-3355): 53-58MB/s.

Speed USB2.0/3.0(ET10k->Unitek Y-3355): 23MB/s.

My 8TB disk is 75% full. 6TB is empty. But Windows doesn't cooperate with ext4. Such a situation I couldn't predict...

Never mind. Thanks for all.

[betacentauri]

There are ext2 drivers for windows (never used them). Afaik they can also read ext4.

[Erik Slagter]

And yes indeed, Windows support for ext is very lousy. For Microsoft there is no universe outside Microsoft.

[Pr2]

For Apple neither

I've found for Windows Ext2Fsd (second, Disk Internal Linux Reader read only Ext2/3/4). It installs special driver and anyone can read/write in Ext2/3/4 from Windows2k ups . I've tried to copy (Win7, eSATA) movie (2048MB file TS) from prepared yesterday HD: 70MB/s. And back: 60MB/s. Attentione for another problem: XP doesn't serve GPT partition (even not on large HDs)!

And a little ass-shelter from author:

WARNINGS:

     The driver may crash your system and ruin your data unexpectedly,
    since there might be software conflicts and I could only test it
    on some of the popular platforms. You should use it with care and
    use it at your own risk!

My migration from NTFS to Ext4 needs copy 6TB data - about 36-48 hours non-stop... Great minus.

Great plus it's increase distance from Microsoft

I am an IT lay person and maybe I misunderstood but - in Mini Tool Partition Manager you may be able to read/browse Linux (ext2/3/4) from Windows. Also from EaseUS Partition Manager...

 

If you wanna browse and/or transfer stuff, then File Zilla Client or so does the job, I think...

 

There is also a freeware proggy for reading Linux from Windows, I forgot the name...

 

Slow maybe but...

 

edit: yes, I think fsd is what I had once, long ago...

I want to have (from Windows 7) normal access (open movie files, move or copy them to another HD (NTFS or Ext4), maybe edit them) to files on partition Ext4.

[gorski]

File Zilla Client.

[kuszmar]

I've done it. Prepared in such way HD is invisible from Win7(+ext2Fsd) and Puppy Linux. I've checked Primery and Sec. GPT - Prim. GPT is empty! I've copied Sec. to Prime (with exchange Current and Backup LBA) but without success. Maybe deferences are deeper... I don't know what's going on.

[kuszmar]

File Zilla Client.

I am an IT more lay person then you, and don't understand, how FZClient can recognize files on HD invizible for OS.

[MiLo]

Default format is ext4 with large cluster support. Windows will see this as "unformatted". Requires Linux 3.x (I think >= 2.6.37 might work) or newer. You'll probably just need a newer version of your distro.

 

If I remember correctly, it only creates GPT partitions when the disk is over 3TB.

[gorski]

If you mount it (say, by a Device Manager), then FIleZilla Client will see it where it is mounted (see the attached screenshot).

 

I have done many a transfer like that.

 

Look:

 FZC.jpg   168.34KB   7 downloads

 

On the left is my laptop and on the right is Red Eagle STB with an external HDD mounted as HDD and you can easily transfer stuff to and fro...

 

In my "A pretty thorough PBNIGMA II VX guide for Ferrari 500 HD by gorski_12.12.12" - on page 29 you have info as to how to work with FZC. Transfers are easy and they work, if they are not very fast...

 

You also have detailed info how to mount a device and so on...

 

If you really are worse than me maybe this can help...

I've checked both partitions by tune2fs -l /dev/... and that "made by xtrend" has extra feature "bigalloc" and exists there clusters (64x block).  Ext2fsd for Windows doesn't support it (but extent, large_file and huge_file supports...) and other Extended Attributes (info from Project site).

So i've to resign from clusters if I want use ext4 partition from Win.
