Default Review: HDD Extern Silicon Power Armor A70

1. Introducere, prezentare, ambalaj


Compania Silicon Power Computer & Communications Inc. a fost fondata in 2003 si produce solutii de stocare externe, carduri de memorie, cititori de carduri de memorie, stickuri USB, SSD-uri si memorii DRAM pentru calculatoare.

In testul urmator va prezint o solutie de stocare externa, care poarta numele Armor A70. Cand vorbim despre hard-disk-uri externe putem sa le impartim in doua categorii. In prima categorie intra harduri cu dimensiuni mici (in cele mai multe cazuri au un HDD de 2.5" inauntru), aici accentul este pus pe mobilitate. In a doua categorie gasim harduri externe cu un HDD de 3.5" inauntru, unde accentul este pus pe viteza si pe capacitate mai mare.
Ce avantaje au hardurile 2.5" fata de 3.5" ? In primul rand cele de 2.5" sunt mai mobile, datorita faptului ca nu necesita alimentare suplimentara, este suficienta alimentarea din portul USB, au dimensiuni mai mici, asa incap si intr-un buzunar mai mare.

Asa cum ne sugereaza si numele produsului, avem de-a face cu un HDD "survivor", rezistent la apa, lovituri, socuri, presiune si praf. Aceste aspecte nu sunt numai "inscriptionate" pe cutie, ci produsul corespunde cu niste standarde, printre care "IEC 529 IPX7" (apa) si "MIL-STD-810F 516.5" (lovituri, soc).


Desi corespunde cu aceste standarde, functionalitatea produsului in conditiile extreme nu este optima si exteriorul poate sa se deterioreze chiar daca in urma impactului datele nu se vor pierde. Din acesta cauza nu am testat produsul in cazuri extreme, aruncat prin balcon, pus intr-o galeata de apa, etc, am incredere in testele care au fost facute pentru a obtine standardele respective.


HDD-ul se conecteaza la PC prin portul USB (1.1 sau 2.0) si este disponibil in capacitati de 250GB, 320GB, 500GB si 640GB. Este compatibil cu orice sistem de operare si este valabil in culori negru si rosu. Are o garantie de doi ani.

Hardul vine intr-o cutie solida, pe care putem vedea cam orice informatie despre el. Pachetul include, pe langa HDD-ul, un cablu USB (defapt doua), manual si un CD cu utilitarul SP Widget pe el.

2. Silicon Power Armor A70 500GB

Exemplarul testat are 500GB si are culoarea nearga mat, cu emblema Silicon Power pe el. Carcasa este dintr-o singura bucata de aluminiu, cu o iesire USB normala in coltul de sus, izolat ermetic cu un "dop" de cauciuc. Langa portul USB avem un LED de culoare albastra, care sta aprins cand avem hard-ul conectat la PC si palpaie rapid cand avem transfer intre HDD si PC.






Pe partea celalalta gasim un cablu USB scurt de rezerva, pentru cei care se uita acasa, pierd cablul mare. Acest cablu mic isi are locul propriu in carcasa hardului, ridicand nivelul de mobilitate al acestuia.

Carcasa de aluminiu este izolata de doua margini de plasctic (intrand ca niste "dopuri" ), la care se adauga cate o garnitura de cauciuc care nu permite intrarea apei in interior.

In interior, asa cum era si de asteptat, gasim un HDD de laptop in dimensiunea de 2.5", modelul Western Digital Scorpio Blue WD5000BEVT. Ajuns la HDD, putem observa ca si el este protejat de niste garnituri de cauciuc, de aceasta data impotriva socurilor si caderilor.

4. Concluzii

In ziua de astazi, odata cu evolutia IT-ului, creste si cantitatea datelor cu care lucram zi de zi. Fie ca folosim PC-ul pentru distractie (jocuri, filme, etc.) sau lucram pe el, ne intalnim cu cantitati mari de informatii, care dupa caz trebuie salvate, transportate sau transferate la un alt calculator. La date cu volum mai mici ne ajuta inscriptionarea lor pe un CD sau DVD, dar la date mai mari ne ajuta mai mult un hard-disk extern. Datorita faptului ca avem un dispozitiv de stocare externa, care dupa caz poate fi la fel de mare ca al unui PC, ne poate ajuta sa transportam datele importante sau neccsare cu noi.
Armor A70 nu este doar un hard-disk extern portabil, dar ne ofera si protejarea datelor impotriva loviturilor, socurilor, prafului si apei. Inginerii de le Silicon Power s-au gandit si la uituci, si au inclus langa HDD un cablu de date mai micut, care isi are locul in carcasa hardului, aceasta fiind aproape imposibil de pierdut sau uitat "acasa".

Per total mi-a placut solutia de stocare de la Silicon Power, denumit Armor A70, din mai multe motive. Primul ar fi aspectul vizual, care este unul solid, fara briz-brizuri, are culoarea neagra mat si nu este nici lucios (unde s-ar vedea amprentele). Pe langa aspectul vizual placut are si o viteza de transfer foarte buna (ce ne permite tehnologia USB 2.0), nu necesita curent separat prin vreun adaptor si nu in ultimul rand are diferite protectii impotriva factorilor externi (apa, praf, socuri) pentru protejarea datelor de pe el.

Singurul lucru care nu mi-a placut este ca nu foloseste un cablu USB - miniUSB (mai general, mai usor de gasit) pentru conectare la PC, ci un cablu USB - USB, tata pe ambele capete.

Pretul recomandat de catre producator pentru tara noastra, pentru varianta testata (500GB) este de 320 RON.

5. Bonus - Silicon Power Touch 830 8GB

Sunt sigur ca este cunoscuta situatia de toata lumea care are contact zilnic cu PC-ul, cand vrem sa luam ceva date de la un prieten, de la serviciu si nu avem la dispozitie un HDD extern, nu avem blank-uri CD sau DVD. In aceste cazuri este binevenit un stick USB in buzunar, in portofel, pe post de breloc, atasat la telefonul mobil, etc. Datorita dimensiunilor mici, aceste dispozitive, numite stick-uri USB se pot purta sau ascunde in locurile mai sus mentionate.

Dupa cum v-am spus si in introducere, firma Silicon Power produce si stick-uri USB de mai multe dimensiuni si forme.
In plus, va voi prezenta un stick USB cu un design deosebit, produs tot de firma Silicon Power, modelul Touch 830.

Stick-ul vine intr-o cutie mica si transparenta. Lantisorul inclus ne permite atasarea stick-ului in diverse locatii. Este disponibil in capacitati de 2GB, 4GB, 8GB si 16GB fiind compatibil cu orice sistem de operare. Producatorul ofera garantie pe viata pentru acest produs.

Datorita faptului ca este facut folosind arhitectura COB (Chip-On-Board), stick-ul este rezistent la apa, la virbratii si la praf. Are carcasa din otel inoxidabil, culoare argintie, o dimeniune de aproximativ 3 cm lungime si 1cm latime si o greutate de 4 grame. Conectarea la portul USB este solida, dar daca nu suntem atenti il putem conecta si invers, cauzand un scurt circuit temporar in portul USB.

MB: DFI LANParty UT X58-T3eH8,
RAM: 3x1G Crucial Ballistix D9GTS @ 1600 7-7-7-21 1T,

Dupa testare, viteza de transfer a fost de aproximativ 24-25MB/s la citire si 9MB/s la scriere pentru acest dispozitiv USB.

Am fost foarte incantat de acest stick, singurul lucru care consider ca ii lipseste este un led de activitate.

Pretul recomandat de producator pentru Romania este de 62 RON pentru varianta testata (8GB).
