Listed here are the outcomes of the 2016 runtime shootout

Your debut is iFlash-Solo and iFlash-Quad, it is extremely fascinating to see how four MicroSDs are compared to full-measurement SD cards used in iFlash-Solo & iFlash-Dual [19659002] In April 2016 all SD iFlash adapters upgraded to a new platform (internally referred to as iFlash85), and this new platform, I squeezed just a little more effectivity chipset, as well as lowered power and begin-up occasions – Nevertheless, the aggressive power-saving utilized by the iPod signifies that the iFlash card sits idle more often than not, so this won’t lead to much change within the last occasions compared to the earlier platform.


The check is pretty simple – obtain each recording choice with the same music, click on play and see how long your iPod lasts. Although in follow, the utilization occasions are shorter, it nonetheless offers a really useful comparability between totally different storage media.

The check was performed with 7.5 g iPod Basic, initially included on a 160 GB arduous drive. I chose this because the original 160 GB onerous drive could be very efficient when rotating disk disks and seven.5 g is probably the most powerful iPod of this era.

Two playlists have been created, consisting of 320Kbps MP3 tracks, other Lossless m4a tracks. I made a decision to do that because the iPod reading from the storage gadget varies with the bit fee of the music – for instance, with a 320 Kbps MP3 disc, the drive is read every eight to 12 minutes, where the frequency converter is learn each 1-three minutes as with the high-bit lossless m4a. A very dramatic difference with an incredible influence on runtime results

In iFlash-Dual and iFlash-Quad checks, we made positive that playlist tracks have been spread on a number of SD cards, easily made with a disk analyzer and synchronized manually in iTunes


] I ran a few of the inverter benchmarking to get a feel for the read and write speeds of each media. Since this was a check from a computer to an iPod, the outcomes would ultimately be restricted to the maximum allowed by the bus.

mSata and HDD hit the USB2.0 restrict about. 22 MB / s is read, and above all, 32Mb / s syncing to iPod. The SOLO / DUAL routes are round right here. 23Mb / s writes and 14Mb / s reads – this is anticipated because the SD platform is restricted for 25Mb / s switch charges. The DUAL exhibits a 1Mb / s enchancment in studying velocity, which is lower than the UHS-U3 class velocity compared to the U1 class.

Unfortunately, MicroSD playing cards have not reached the same velocity as full-sized SD cards but, however Sandisk 200Gb labored properly and are the fastest examined MicroSD playing cards.

Let's check out what this does for the actual use of iPod by measuring the beginning-up time and the way lengthy each storage medium fills up – The buffer on iPod exhibits this operating time and experience when searching and looking for lengthy tracks

  Storage Access Times

Storage Entry Occasions

] Apparently, the recording read velocity appears to haven’t any effect on the boot time as much as you anticipate. Given mSata, speeds are a lot quicker than SDXC. The SDXC takes solely 2 seconds earlier than it begins – an important factor is the time that iPod takes to parse by way of the iTunes database. Referring to, the newly restored iPod will start in about 24 seconds.

Although SD cards are the slowest uncooked price, they are palms down winners in the Learn-forward and Entry Occasions check. The onerous drive is the slowest in 7.5 seconds, which was expected as a result of the spin-up of the drive takes greater than 1 second before the actual knowledge is read. MSata comes second when the time is 6.7 seconds. This is shocking, but the SATA bus really takes some time to shake arms and negotiate a link from an influence supply. The SD card is designed to be used for lower than 100 mS, and the SD card has nearly on the spot entry – leading to five.7 and 5.6 seconds of blistering.

The consumer expertise reflects the above results. remaining clean searching of hundreds of albums, near immediate album artwork display goes to SD cards … ..

Runtime Exams

In order mentioned above, we have now two playlists, one 320kbps MP3 (~ 6Mb / track) and the opposite is huge bit price lossless m4a file (~ 30 MB per track)

The iPod was absolutely charged, reset, and booted, the playlist was selected and performed. This was completed for MP3 and Lossless playlists for every recording combination. I set up a low-tech IP digital camera to take a photo of the iPod each minute, giving me the time exactly when the iPod was shut down (to the nearest minute).

 Runtime Comparison

Runtime Comparability

This was all the time the anticipated end result, mSata drives will pull fairly giant currents during startup and the iFlash 100 itself is a excessive efficiency chipset that may convert a very fast SATA bus to a slower iPod PATA bus. The onerous drive restored secure performance and sat within the center area, but has the disadvantage of its restricted capability.

Probably the most shocking component of those outcomes is in the area of ​​the SD card! The IFlash-Quad wth 4 MicroSD card has the same operating time as one full-measurement SD card. The IFlash-Dual also comes with wonderful driving occasions – all SD card-based mostly iFlash adapters return to superb occasions

iFlash-Twin & iFlash-Quad is ready to restore good driving occasions because of extremely environment friendly power-saving options. All cards that are not in standby / hibernation, so most frequently just one card is lively and used.

Power Consumption Checks

As a way to analyze runtime results, I needed to take a look at every recording choice for precise power consumption and the way much energy the totally different card mixtures eat.

On this check collection I learn the entire consecutive full space for storing when storing power consumption – outcomes are averaged

  Recording power consumption

Recording power consumption (decrease is best)

Average energy consumption figures only share a part of the story, whereas two mSata drives use comparable energy energy consumption. For instance, ph won’t be displayed during startup, 1Tb will take far more power for a 500 Gb mannequin with lower capacity.

I also needed to see how totally different individual SD playing cards various in power consumption, so each card was loaded into particular hardware where I can measure the facility consumption of the cardboard itself, the same consecutive read check was performed again

  Card power consumption

Card energy consumption

WOW! While Sandisk 200Gb MicroSD solely pulls an astonishing power of ~ 65mA whereas reading only 214 mW, the Samsung EVO 128Gb MicroSD in turn pulls an unimaginable ~ 110mA of energy consumption at 363 mW. This is even larger than the complete-measurement Kingston U1 512Gb, which solely raises ~ 95mA power consumption by just 313 mW.


I feel all of the units work nicely and supply most users loads of musical enjoyment between payments. and the way far are you from the USB charging port in your day by day life?

I want to level out that mSata drives have various ranges of energy consumption, a number of 240 GB to 256 Gb mSata drives restore runtimes which are approaching the arduous disk. Once more, the 500 Gb vary has various energy consumption levels.

iFlash-Solo, iFlash-Dual, and iFlash-Quad restored wonderful driving occasions, and any mixture of card capability, get the most effective in school

MicroSD card energy consumption figures present an fascinating opportunity that four Sandisk 200Gb MicroSD cards that offer you The cool 800GB iPod or 2, installed in the MicroSD SD Adapters in iFlash-Twin, provides you 400Gb worth. a number of hours runtime compared to one full measurement 256Gb or 512Gb !!

In fact you possibly can set up MicroSD cards with both iFlash-Dual or iFlash-Solo utilizing a passive MicroSD SD adapter if you need additional

Using mSata service, buying and selling takes one of the best worth per GB, which would be the selection in case you want the very best capability preserving prices down. Nevertheless, iFlash-DUAL and iFlash-QUAD challenge this concept – 2 x 256 Gb SDXC or even four x 128 Gb MicroSD may be purchased for lower than one 512 Gb mSata

What about CF Playing cards… .. [19659002] No Compact Flash card and iFlash alone offer you about 20% runtime progress in comparison with SDXC. But the worth of 128 GB plus capability per Gb is just too expensive. I’ve been lucky to check a number of high-capability CF card know-how samples, and located suitable together with your iPod as suspicious, many have been taken ailing LBA48 (ie 256GB CF cards), which induced the return circuit issues 7.5g's in your iPod. ]
